A plane leaves Singapore airport at 07:45 to fly to Sydney. The plane flies at an average speed of 757.2 km/h. The distance from Singapore to Sydney is 6310 km. The time in Sydney is 2 hours ahead of Singapore time. Calculate the local time when the plane arrives in Sydney. Give your answer in the form hours:minutes using the 24-hour clock.​

Answers

Answer 1

The  local time in Sydney when the plane arrives will be 18:58, or 6:58 PM on a 24-hour clock.

How to find arrival time for the plane?

The time difference between Speed and Sydney is 2 hours, and the plane will take some time to fly from Singapore to Sydney at an Speed of 757.2 km/h over a distance of 6310 km.

The time it takes the plane to fly from Speed to Sydney can be calculated as:

time = distance / Speed= 6310 km / 757.2 km/h = 8.33Speed

So the plane will take 8.33 hours to fly from Singapore toSpeed

Now we need to add the 2-hour time difference between Singapore and Sydney to determine the local time in Sydney when the plane arrives.

07:45 (Singapore time) + 8.33 hours (flight time) + 2 hours (time difference) = 18:58

Therefore, the local time in Sydney when the plane arrives will be 18:58, or 6:58 PM on a 24-hour clock.

Answers

The  evaluated probability that Sue travel to France this summer is 0.67, under the condition that she just returned from her winter vacation in Mexico.

For the required problem we have to apply  Bayes' theorem.

Let  us consider that A is the event that Sue goes to France in the summer and B be the event that Sue goes to Mexico in the winter.

Now,

P(A and B) = P(B) × P(A|B)

= 0.40

P(B) = 0.60

Therefore now we have to find P(A|B),  which means the probability that Sue traveled to France after coming from Mexico

Applying Bayes' theorem,

P(A|B) = P(B|A) × P(A) / P(B)

It is given that P(B|A) = P(A and B) / P(A), then

P(A|B) = (P(A and B) / P(A)) × P(A) / P(B)

P(A|B) = P(A and B) / P(B)

The coach recorded the time it took 14 students to run a mile. The times are as follows: 9:23, 8:15, 9:23, 9:01, 6:55, 7:20, 9:14, 6:21, 7:12, 7:34, 6:10, 9:15, 9:18. Use the data set to complete the frequency table. Then use the table to make a histogram

Answers

The histogram for the frequency table is illustrated below.

To create the frequency table, we need to count how many times each time appears in the data set. The time 9:23 appears twice, so we would put a frequency of 2 in the row corresponding to 9:23. We do this for each time in the data set.

Here is the completed frequency table:

Time Frequency

6:10 1

6:21 1

6:55 1

7:12 1

7:20 1

7:34 1

8:15 1

9:01 1

9:14 1

9:15 1

9:18 1

9:23 2

As you can see, each time appears only once or twice in the data set. This tells us that there is no dominant time that most students ran the mile in.

To create the histogram, we'll draw a bar above each time on the x-axis with a height equal to the frequency of that time. For example, there are two times of 9:23, so we'll draw a bar above 9:23 with a height of 2.

As you can see, the histogram shows a relatively even distribution of times. The most common times are around 9 minutes, but there are also several times below 8 minutes and one time below 7 minutes.

find the extremum of each function using the symmetry of its graph. Classify the etremum of the function as maximum or a minimum and state the of x at which it occurs k(x)(300+10x)(5-0.2x)

Answers

The extremum of the function is a minimum at x = -2.5

The given function is k(x)(300+10x)(5-0.2x).

To check for symmetry about the y-axis, we replace x with -x in the given function and simplify as follows:

k(-x)(300-10x)(5+0.2x)

To check for symmetry about the x-axis, we replace y with -y in the given function and simplify as follows:

k(x)(300+10x)(5-0.2x) = -k(x)(-300-10x)(5+0.2x)

To find these points, we set the function equal to zero and solve for x:

k(x)(300+10x)(5-0.2x) = 0

This equation has three solutions:

x = 0

x = -30

x = 25.

The midpoint of the line segment connecting these points is

(x1+x2) ÷ 2 = (-30+25) ÷ 2 = -2.5.

To determine the type of extremum at this point, we need to check the sign of the second derivative. The second derivative of the function is:

k(x)(-1200+x)(0.2x+15)

Since the function is symmetric about the x-axis, the second derivative will be negative at the extremum if it is maximum and positive if it is a minimum.

When x = -2.5, the second derivative is positive, which means that the function has a minimum at x = -2.5.

In △abc , m∠b=20° and m∠c=40°. the angle bisector at a intersects side bc at point d. find the difference between bc and ab if ad = 1

Answers

In the △ABC, the  the difference between bc and ab if ad = 1 is found to be 0.709.

We can use the angle bisector theorem to solve this problem. Let's denote the length of segment BD as x and the length of segment CD as y. Then, we can write,

BD/DC = AB/AC

Using the angle bisector theorem, we know that AB/AC = BD/DC, so we can substitute to get,

x/y = AB/AC

We can solve for AB by multiplying both sides by AC,

AB = x/y * AC

Now, we can use the law of sines to find the length of AC. We have,

sin(20°)/AB = sin(140°)/AC

Solving for AC, we get,

AC = AB * sin(20°) / sin(140°)

Substituting the expression we found for AB, we get,

AC = x/yACsin(20°) / sin(140°)

Simplifying, we get,

y = xsin(140°) / (sin(20°) - sin(140°))

We know that AD = 1, so we can use the Pythagorean theorem to find BC:

BC² = BD² + CD²

Substituting the expressions we found for BD and CD, we get,

BC² = x² + y²

Substituting the expression we found for y, we get,

BC² = x² + (xsin(140°) / (sin(20°) - sin(140°)))²

Simplifying, we get,

BC² = x²(1+sin²(140°)/(sin²(20°)-2sin(20°)sin(140°)+sin²(140°)))

Using the identity sin(140°) = sin(180° - 40°) = sin(40°), we can simplify further.

Now, we can substitute x = AD = 1 and sing a calculator, we can evaluate this expression to get,

BC² ≈ 2.917

Taking the square root, we get,

BC ≈ 1.709

Therefore, the difference between BC and AB is 0.709.

Answers

Type I error in this situation would mean option a. Concluding that the bags are being under filled when they actually aren't.


A Type I error occurs when the null hypothesis (in this case, that the true mean net weight is 14 ounces) is rejected when it is actually true. In other words, it is the error of concluding that there is evidence for the alternative hypothesis (that the true mean net weight is less than 14 ounces) when there is not.

In this situation, if a Type I error is made, it would mean that the bags are being under filled (i.e. the true mean net weight is less than 14 ounces) when in reality they are not. This would lead to incorrect conclusions and potentially negative consequences for the manufacturer.

It's important to note that the probability of making a Type I error can be controlled by choosing an appropriate level of significance (usually denoted by alpha) for the hypothesis test. For example, if alpha is set at 0.05, there is a 5% chance of making a Type I error.

In summary, a Type I error in this situation would mean incorrectly concluding that the bags are being under filled when they actually are not, and the probability of making such an error can be controlled by choosing an appropriate level of significance for the hypothesis test.

Answers

The volume of the large box is 200 cubic inches. The volume of the small box is 150 cubic inches. The difference in the volumes of the two boxes is 50 cubic inches. The units that should be used for each of these answers is cubic inches.

To find the volume of each box, we'll use the formula for the volume of a rectangular prism: Volume = Length × Width × Height.

For the larger box, the dimensions are:
Length = 8 inches
Width = 2.5 inches
Height = 10 inches

Volume of large box = 8 × 2.5 × 10 = 200 cubic inches

For the smaller box, its length is 75% of the larger box's length:
Length = 0.75 × 8 = 6 inches

The width and height remain the same, so the dimensions are:
Length = 6 inches
Width = 2.5 inches
Height = 10 inches

Volume of small box = 6 × 2.5 × 10 = 150 cubic inches

The difference in the volumes of the two boxes is:

The terminal side of angle λ intersects the unit circle at point (-0. 358, 0. 934). Based on these coordinates, what is the approximate decimal value of cot(λ)

Answers

If the terminal side of angle λ intersects the unit circle at point (-0. 358, 0. 934), the approximate decimal value of cot(λ) is -0.383.

To find the approximate decimal value of cot(λ), we first need to determine the values of x and y on the unit circle. Since the given point (-0.358, 0.934) lies on the unit circle, we can use the Pythagorean theorem to find the missing side:

x² + y² = 1
(-0.358)² + (0.934)² = 1
0.128 + 0.872 = 1
1 = 1

Therefore, we have x = -0.358 and y = 0.934. Since cot(λ) = cos(λ)/sin(λ), we can use the values of x and y to calculate the cosine and sine of λ:

cos(λ) = x = -0.358
sin(λ) = y = 0.934

Substituting these values into the formula for cot(λ), we get:

cot(λ) = cos(λ)/sin(λ) = -0.358/0.934 ≈ -0.383

Therefore, the approximate decimal value of cot(λ) is -0.383.

Step-by-step explanation:

remember the original trigonometric triangle inside the norm circle (radius = 1).

sine is the up/down distance from the triangle baseline or corresponding circle diameter.

cosine is the left/right distance from the center of the circle (and the point of the angle).

for larger triangles and circles all these function results need to be multiplied by the actual radius (which we skipped for the norm circle, as a multiplication by 1 is not changing anything).

when you look at the triangle with K representing the angle, we have 10 a the cosine value, 24 as the sine value and 26 as the radius.

so,

10 = cos(K) × 26

cos(K) = 10/26 = 5/13

how many paths are there from point (0,0) to (90,160) if every step increments one coordinate and leaves the other unchanged and you want the path to go through (80,70)?

Answers

There are 4.097 x [tex]10^43[/tex] paths from (0,0) to (90,160) that pass through (80,70).

To calculate the number of paths from (0,0) to (90,160) while passing through (80,70), we need to break down the problem into smaller steps.

First, we can calculate the number of paths from (0,0) to (80,70) and then

multiply that by the number of paths from (80,70) to (90,160).

To go from (0,0) to (80,70), we need to take 80 steps to the right and 70 steps up, which gives us a total of 150 steps. The order in which we take these steps doesn't matter, so we can think of it as choosing 70 steps out of 150 to be up. This can be calculated using the binomial coefficient, which gives us (150 choose 70) = 2.364 x  [tex]10^43[/tex]

To go from (80,70) to (90,160), we need to take 10 steps to the right and 90 steps up, which gives us a total of 100 steps. Using the same method as above, the number of paths from (80,70) to (90,160) is (100 choose 10) = 17,310,309.

Multiplying these two values together, we get the total number of paths from (0,0) to (90,160) that pass through (80,70):

(2.364 x 10^34) x (17,310,309) = 4.097 x  [tex]10^43[/tex]

Answers

The cost of one apple is $2.15.

To find the cost of one apple, we can set up a system of equations with the given information. Let's use A for the cost of one apple and B for the cost of one banana:

1) 4A + 9B = $12.70
2) 8A + B = $17.70

Now, we can solve this system of equations. We can multiply equation 1 by 2 to match the number of apples in equation 2:

1) 8A + 18B = $25.40

Now subtract equation 2 from the modified equation 1:

(8A + 18B) - (8A + B) = $25.40 - $17.70
17B = $7.70

Now, divide by 17 to find the cost of one banana:
B = $7.70 / 17 = $0.45

Now that we know the cost of one banana, we can substitute B in equation 2 to find the cost of one apple:

8A + ($0.45) = $17.70
8A = $17.25
A = $17.25 / 8 = $2.15

Answers

Mario can afford to buy a maximum of 12 hamburgers from the local store.

How to find the number of hamburgers Mario can afford to buy given certain prices and a budget?

Let's assume Mario can buy "h" hamburgers.

The cost of each hamburger is $2.90, and Mario wants to buy "h" hamburgers, so the total cost of hamburgers would be 2.90h.

He is also buying one packet of hamburger rolls, which costs $4.75.

Therefore, the total amount he can spend at the store must be less than or equal to his budget of $39.55.

Putting it all together, the inequality representing this situation is:

2.90h + 4.75 ≤ 39.55

To find out how many hamburgers Mario can afford to buy, we need to solve the inequality:

2.90h + 4.75 ≤ 39.55

Subtracting 4.75 from both sides of the inequality:

2.90h ≤ 34.80

Next, divide both sides of the inequality by 2.90:

h ≤ [tex]\frac{34.80 }{ 2.90}[/tex]

substitute c = 3 into either of the 2 equations and solve for a

substituting into (1)

4a + 3 = 33 ( subtract 3 from both sides )

4a = 30 ( divide both sides by 4 )

a = 7.5

2.1.2. What is the sum of handshakes that will be made by the first and second ​

Answers

67 is the sum of handshakes given by the first and second participants.

Let n be the total number of participants in the workshop venue.

i.e, here n= 35

For the first participant, the number of handshakes is = (n-1)

= (35-1)

= 34

The number of handshakes by the second participant is also same as that of the first participant = 34

The number of handshakes given by the first and second participants together = (first participant handshake + second participant handshake - 1)

= (34 + 34 -1)

= 68-1

= 67

Hence 67 is the sum of handshakes given by the first and second participants.

The sides of the base of a right square pyramid are 3 meters in length, and its slant height is 6 meters. if the lengths of the sides of the base and the slant height are each multiplied by 3, by what factor is the surface area multiplied?

a. 12

b. 3^3

c. 3^2

d. 3

Answers

If the base and slant height both are divided by a factor of 3, the surface area will get multiplied by factor, option b, 3².

Here we are given that the square pyramid has a base of 3m and a slant height of 6 m.

The surface area formula for a square pyramid with square edge a and slant height h is

a² + 2a√(a²/4  + h²)

Here, a = 3 and h = 6. Hence we get

3² + 2X3√(3²/4  + 6²)

= 46.108

Now the base and slant height are multiplied by 3. Hence we will get

9a² + 6a√(9a²/4  + 9h²)

414.972

Now, dividing both obtained we will get

414.972/46.108

= 9

= 3²

Hence, it should be multiplied by 3².

13. the area of a rhombus is 484 square millimeters. one diagonal is one-half as long
as the other diagonal. find the length of each diagonal.

Answers

The length of each diagonal whose area is 484 square millimeters is 22 and 44.

Area of rhombus = 484 square millimeters

Let one diagonal of rhombus = p

other diagonal of rhombus = q

The length of one diagonal of rhombus is one-half as long as the other diagonal of rhombus

p = q/2

Area of diagonal = [tex]\frac{1}{2}d_{1}d_{2}[/tex]

Area of diagonal = [tex]\frac{1}{2}pq[/tex]

Area of diagonal = [tex]\frac{1}{2}\frac{q}{2}q[/tex]

484 = [tex]\frac{1}{4}q^{2}[/tex]

q² = 1936

q = 44 millimeter

p = q/2

p = 44/2

p = 22 millimeter

The length of each diagonal p and q is 22 mm and 44 mm respectively

In circle P with m \angle NPQ= 104m∠NPQ=104 and NP=9NP=9 units find area of sector NPQ. Round to the nearest hundredth

Answers

To find the area of the sector NPQ, we first need to find the measure of the central angle that intercepts the arc PQ. We know that the measure of angle NPQ is 104 degrees, and since it is an inscribed angle, its measure is half the measure of the central angle that intercepts the same arc. Therefore, the central angle measure is 208 degrees.

To find the area of the sector, we use the formula:

Area of sector = (central angle measure/360) x pi x radius^2

We know that the radius of circle P is NP = 9 units. Plugging in the values, we get:

Area of sector NPQ = (208/360) x pi x 9^2
= (0.5778) x 81pi
= 46.99 square units

Rounding to the nearest hundredth, the area of the sector NPQ is 47.00 square units.

Calculating the relative frequencies from the data given in the table. Choose all that correctly describe an association between favorite subject and grade

Answers

From the given data, the statement "A higher percentage of 8th graders than 7th graders prefer Math/Science" is correct. So, correct option is C.

To calculate the relative frequencies, we need to divide the frequency of each category by the total number of responses.

For 7th grade:

Relative frequency of English: 38/116 = 0.3276

Relative frequency of History: 36/116 = 0.3103

Relative frequency of Math/Science: 28/116 = 0.2414

Relative frequency of Other: 14/116 = 0.1207

For 8th grade:

Relative frequency of English: 47/182 = 0.2582

Relative frequency of History: 45/182 = 0.2473

Relative frequency of Math/Science: 72/182 = 0.3956

Relative frequency of Other: 18/182 = 0.0989

From the data, we can see that a higher percentage of 8th graders prefer Math/Science than 7th graders. Therefore, the statement "A higher percentage of 8th graders than 7th graders prefer Math/Science" correctly describes the association between favorite subject and grade.

The statements "A higher percentage of 8th graders than 7th graders prefer History" and "A higher percentage of 7th graders than 8th graders prefer English" are incorrect as the relative frequencies for these subjects are similar in both grades.

Overall, we can conclude that the choice of favorite subject is not strongly associated with the grade level of the students.

So, correct option is C.
