Mr. and Mrs. Hodges are shopping for
a new vehicle. They found these prices
for cars that suit their family's needs:
26,500 23,400, 19,950, 47,800 16,800 18,400
What are the mean and median of the
prices they found?
Answer:
See below
Step-by-step explanation:
Arrange the list in ascending order
16 800 18400 19 950 23 400 26 500 47 800
MEDIAN is the middle number ...since there are TWO in the middle it is the average of the two (19950 + 23400) /2 = 21675
MEAN is the average...add all of the numbers and divide by 6
= 25475
A business advertises that everything in the store is an additional 10% off the already reduced prices. marcus picks out 2 shirts that are on a 30% off rack. if the shirts are originally priced at $28.99 and $30.29 and there is 6% sales tax, how much does marcus end up paying for them? a. $39.59 b. $37.70 c. $37.35 d. $35.57
The amount that marcus end up paying for the two shirts originally priced at $28.99 and $30.29 is given by: Option A: $39.59
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
[tex]\dfrac{a}{100} \times b[/tex]
For this case, we're given that:
Cost of two shirts originally is $28.99 and $30.29
30% is off on each of them, so we get:
New price of each shirt = Old price of each shirt - 30% of old price of each shirt
New price of each shirt = [tex]28.99 - \dfrac{28.99}{100} \times 30[/tex] and [tex]30.29- \dfrac{30.29}{100} \times 30[/tex]
This sums up to $41.496
Now, at this price, there'd be application of 10% additional discount.
That will make the new price as:
[tex]41.496 - \dfrac{41.496}{100} \times 10 =37.3464[/tex]
Now, on this price, there'd be applied 6% sales tax
So, the amount he paid for 2 shirts = discounted price + 6% tax on discounted amount
= [tex]37.3464 + \dfrac{37.3464}{100} \times 6 \approx 39.59 \: \rm dollars[/tex]
Thus, the amount that marcus end up paying for the two shirts originally priced at $28.99 and $30.29 is given by: Option A: $39.59

what is BOC? please help me!
OA, OB, and OC are all radii of the circle so they have the same length, 12 in. ∆ AOB is therefore isosceles, so the angles at the vertices A and B are congruent. The interior angles of any triangle sum to 180° in measure, so
30° + 2 m∠A = 180° ⇒ m∠A = 75°
Draw an altitude in ∆ AOB that connects the vertex O to the midpoint of AB; this is the height h of ∆ AOB and bisects ∆ AOB into two 15°-75°-90° right triangles. Solve for h and the length of the base AB using trigonometry:
sin(15°) = (AB/2) / (12 in) ⇒ AB = (24 in) sin(15°) ≈ 6.212 in
sin(75°) = h / (12 in) ⇒ h = (12 in) sin(75°) ≈ 11.591 in
Then the area of ∆ AOB is
1/2 (AB) h = (144 in²) sin(15°) sin(75°)
= (72 in²) (cos(60°) - cos(90°))
= 36 in²
where we use the identity
sin(x) sin(y) = 1/2 (cos(x - y) - cos(x + y))
Let m∠BOC = θ. Then
(area of sector BOC) / θ = (area of ⊙O) / 360°
Solve for θ :
θ = (area of sector BOC) / (area of ⊙O) • 360°
θ = (36 in²) / (π (12 in)²) • 360°
θ = (90/π)° ≈ 28.648°
A researcher decides to split scores on an exam into quartiles. She determines that a score of 64 is at the 25th percentile, a score of 74 is at the 50th percentile, and a score of 80 is at the 75th percentile. What is the interquartile range (IQR) for these data
Answer: IQR = 16
Step-by-step explanation:
The given data is 25 th percentile is 64, 50th percentile is 74 and 75 th percentile is 80.
percentage : 25 50 75
score : 64 74 80
Median:- The median is obtained by first arranging the data in ascending or descending order and applying the following rule.
If the number of observations is odd, then the median is observation
term
If the number of observations is even, then the median is observation and observations.
given n=3, middle term is '74'
In this given data the median is (M) = 74
Interquartile range IQR = median of upper half-median of lower half
= 80-64
= 16
IQR = 16
Determine the equation of the line with the following characteristics.
Slope 3, passing through (2,3) and (-1,9)
Answer:
y = 3x - 3
Step-by-step explanation:
Given, (2,3) and (-1,9), m = 3
Equation of a straight line is y = mx + c
Here, y = 3, x = 2 and m = 3
Substituting the values in y = mx + c we get,
3 = 3(2) + c
c + 6 = 3
c = 3 - 6
c = -3
So, the equation of the line is y = 3x - 3 (Answer).

Given that a randomly chosen US Airways (US) flight arrives in Denver (DEN), what is the probability that it arrives on time?
Using the stated percentage, it is determined that it has a 0.877 = 87.7% chance of arriving on time.
The number of desired outcomes divided by the total number of outcomes yields a probability.
A percentage can be regarded as a probability over a big sample.
In this question, 87.7% of flights arrive on time in Atlanta, based on a significant number of flights. As a result, there is a 0.877 = 87.7% chance that it will arrive on time.
Answer: 86.1%

Answer:
A: (x, y) → (x + 1, y + 2); (-2, 6)
Step-by-step explanation:
The A vertex started at (-3, 4), [ x = (-3) , y = 4 ]The triangle translates two units up meaning y+2The trinalge also translates one unit to the right meaning x+1, but if it was to the left it would be minus, since we are basically graphing x and y.Equation needs to have x + 1 and y + 2 which is only found in the answer A equation. (x + 1, y + 2)Verify X and Y final vertex. x originally equalled (-3), if we take that integer and +1 we get (-2). and the same for y, y originally equalled 4, if we take that number and +2 we get 6.which makes (-2, 6)Which perfectly equals our selected equation. The answer is A.

There are seven cows in a pasture and five of those cows are red. What
fraction of the cows are red?
Answer:
5/7
Step-by-step explanation:
Since we have 7 cows in total our denominator would be 7 for now. 5 of the cows are red, so 5/7. Since we can't simplify 5/7 that is our final answer.

What is the probability that if a coin lands on heads and the number cube shows 5
Answer:
Not sure
Step-by-step explanation:
Well I’m just guessing these numbers but…
For the coin it is one minus the probability of the coin landing on tails minus the tiny probability of the coin landing on its edge and balancing there. So something like (1 - 0.499 999 5 - 0.000 001), or 0.499 995; call it as near 0.5 as makes no difference.
For the number cube it is one minus the probability of the cube landing on one, three or five minus the tiny probability of the coin landing on an edge or the even tinier probability of it landing on a corner and balancing there. So something like (1 - 3 * 0.166 666 - 12 * 0.000 000 36 - 8 * 0.000 000 08) , or 0.499 998; call it as near 0.5 as makes no difference.
So the joint probability is the first probability times the second. So 0.5 * 0.5 which is 0.25 for all intents and purposes
