Step-by-step explanation:

(1/6²)⁵ = 1/6¹⁰ = 6^-10

because in the case of exponent of an exponent the exponents are multiplied with each other.

and 1/n = n^-1

(6^-5)² = 6^-10

because as above the exponents are multiplied with each other.

6^-3 / 6⁷ = 6^(-3 - 7) = 6^-10

a^n × a^m = a^(n+m)

a^n / a^m = a^(n-m)

the others are not 6^-10 :

6^-5 × 6² = 6^(-5 + 2) = 6^-3

6⁵×6^-3 / 6^-8 = 6^(5 - 3 - -8) = 6^(5 ‐ 3 + 8) = 6¹⁰

the radius of a disk is given as with a maximum error of . use differentials to estimate the relative error in the calculated area of the disk. please enter your answer in decimal format with three significant digits after the decimal point.

Answers

Using differentials to estimate the relative error in the calculated area of the disk of disk with radius 15 cm is equals to the 3.192%.

We have, a disk with radius of 15 cm.

Maximum error = 0.25

We have to determine the area of the disk. Area is a two dimensional quantity. It is defined as the space occupied by figure or any two dimensional shape. Here, formula for area of disk, A = πr² --(1)

here, r = 15 cm , dr = 0.25

Relative error is defined as the ratio of absolute error in measurement to the oringnal measurement. Differentating the equation (1) with respect to r, dA = d( πr²)

=> dA = 2πr dr

Substitutes the known values, in above formula, dA = 2× π × 15 ×0.25

=> dA = 7.50 × π = 23.55

So, absoulte error in area = 22.55

Original value of area = π(15)² = 706.5 cm²

Now, relative error % = (∆A/A)×100

= (22.55/706.5)×100

= 0.031917 × 100

= 3.1917 ~ 3.192 %

Hence, required value is 3.192%.

you want to obtain a sample to estimate a population proportion. at this point in time, you have no reasonable estimate for the population proportion. you would like to be 99.5% confident that your estimate is within 4% of the true population proportion. how large of a sample size is required?

Answers

The sample size required to estimate a population proportion with a desired level of confidence and margin of error depends on the size of the population and the confidence level desired. In this case, the population proportion is unknown and the desired confidence level is 99.5% with a margin of error of 4%.

To determine the sample size required, we can use the formula:

n = (Z² * p * q) / E²

where n is the sample size, Z is the Z-score corresponding to the desired level of confidence (which for a 99.5% confidence level is 2.81), p is the estimated population proportion (which is 0.5 as we have no reasonable estimate), q is 1-p, and E is the margin of error (which is 0.04).

Plugging in these values, we get:

n = (2.81² * 0.5 * 0.5) / 0.04² ≈ 1381

Therefore, a sample size of at least 1381 is required to estimate the population proportion with 99.5% confidence and a margin of error of 4%.

The bell tower of the cathedral in Pisa, Italy, leans 5.6° from the vertical. A tourist stands 105 m from its base, with the tower leaning directly toward her. She measures the angle of elevation to the top of a the tower to be 29.2°. Find the length of the tower to the nearest meter.

Answers

the tower leans 5.6° from the vertical, so we can draw a line perpendicular to the ground from the top of the tower to find the height. Let's call the height "h". the length of the tower is approximately  [tex]57 meters[/tex] (rounded to the nearest meter).

What is the angle of elevation?

We know that the angle of elevation from the tourist to the top of the tower is [tex]29.2^\circ[/tex]  , so we can label that angle as 29.2°. We also know that the angle between the perpendicular line and the ground is 5.6°, so we can label that angle as 5.6°.

Using trigonometry, we can find the value of h:

[tex]tan(29.2^\circ) = h/105[/tex]

[tex]h = 105^\circ tan(29.2^\circ)[/tex]

[tex]h \approx 55.05[/tex]

So the height of the tower is approximately   [tex]55.05[/tex] meters.

To find the length of the tower, we can use the Pythagorean theorem:

[tex]h^2 + x^2 = (105/cos(5.6^\circ))^2[/tex]

[tex]x^2 = (105/cos(5.6^\circ))^2 - h^2[/tex]

[tex]x \approx 56.67[/tex]

So the length of the tower is approximately [tex]56.67[/tex] meters.

Therefore, the length of the tower is approximately [tex]57[/tex] meters (rounded to the nearest meter).

a laboratory scale is known to have a standard deviation of 0.005 in repeated weightings. scale readings in repeated weightings are normally distributed, with the mean of all possible measurements equal to the true weight of the specimen. a specimen weighted 4 times on this scale. the average weight is 4.53 grams. suppose that we needed a 95% confidence interval for this specimen using this data. what would the margin of error be?

Answers

The margin of error for a 95% confidence interval for this specimen is 0.008 grams. Then the 95% confident specimen's true weight is 0.008 grams of the sample mean of 4.53 grams.

To find the margin of error for a 95% confidence interval, we need to determine the standard error of the mean. The  standard error of the mean formula can be written as:

SE = σ/√n

where:

SE = standard error of the mean,

σ = the standard deviation of the population

n = the sample size.

the standard deviation of the laboratory = 0.005

sample size = 4.

calculating the standard error of the mean:

SE = 0.005/√4

= 0.0025

Next, we need to find the critical value for a 95% confidence interval. the sample size is small (n < 30), then we need to use a t-distribution.

Critical value = 3.182.

The formula for calculating the margin of error is:

ME = t*SE

where :

ME = margin of error

t = critical value = 3.182.

SE = standard error of the mean = 0.0025

By substuting the values, we get:

ME = t*SE

= 3.182*0.0025

= 0.008 grams

Therefore, the margin of error for a 95% confidence interval for this specimen is 0.008 grams. Then the 95% confident specimen's true weight is 0.008 grams of the sample mean of 4.53 grams.

What do you understand by the term Corresponding Angle?

In geometry, corresponding angles are pairs of angles that have the same relative position and the same degree of rotation, in two different geometric figures that are being compared.

More specifically, when two lines are crossed by another line, the angles on one side of the crossing line that are in the same relative position to each other (i.e., they are on the same side of the crossing line and are either both interior angles or both exterior angles), are corresponding angles.

According to question

∠CFE = 72°

In given diagram

DC ║ EF ║ AB and CB is transversal

∴ ∠CFE + ∠BFE = 180° ( Linear pair )

72° + ∠BFE = 180°

∠BFE = 180 - 72

∠BFE = 108°

∵∠DCF = ∠BFE ( Corresponding equal angle )

∠DCF = 108°

∠C = 108°

∠CFE = ∠B (  Corresponding equal angle )

72° = ∠B

∴∠B = 72°

if x^2 + y^2 = m and xy = n, find the value of 16m + 32n

Answers

Answer:

x^4 - mx^2 + n^2 = 0

Step-by-step explanation:

We can use algebraic manipulation to solve for m and n. First, we can square the equation xy = n to get:

(x^2)(y^2) = n^2

Since we also have x^2 + y^2 = m, we can substitute y^2 with m - x^2 to get:

x^2(m - x^2) = n^2

Expanding the left side of the equation, we get:

mx^2 - x^4 = n^2

Multiplying both sides by 16, we get:

16mx^2 - 16x^4 = 16n^2

Adding 32xy to both sides, we get:

16mx^2 + 32xy - 16x^4 = 16n^2 + 32xy

Substituting n for xy, we get:

16mx^2 + 32n - 16x^4 = 16n^2 + 32n

Rearranging the equation, we get:

16mx^2 - 16x^4 - 16n^2 = 0

Dividing both sides by -16, we get:

x^4 - mx^2 + n^2 = 0

Answer:

(4x+4y)²

Step-by-step explanation:

Given x²+y² = m ,xy=n.

Now 16m+32n = 16(m+2n)

= 16(x²+y²+2xy) = 4²(x+y)²[ x²+y²+2xy= (x+y)²]

(4x+4y)².

The area of the trapezoid is 42square kilometers. What is the trapezoid's height, h?

Answers

the height of the trapezoid is 8.4 kilometers. To find the height, h, of a trapezoid when given the area, A, we need to use the formula:

A = ([tex]b_{1} + b_{2}[/tex])h/2

where b1 and b2 are the lengths of the two parallel bases of the trapezoid.

Given that the area of the trapezoid is 42 square kilometers, we can write:

42 = ([tex]b_{1} + b_{2}[/tex])h/2

We can simplify this equation by multiplying both sides by 2:

84 = ([tex]b_{1} + b_{2}[/tex]) h

Now we need to find the values of b1 and b2. Unfortunately, the problem does not provide us with these values. Without them, we cannot find the exact value of h. However, we can provide an example to show how to solve the problem if we have the values of b1 and b2.

Let's say that b1 = 4 km and b2 = 6 km. We can substitute these values into the equation:

84 = (4 + 6)h

Simplifying:

84 = 10h

Dividing both sides by 10:

h = 8.4 km

So, in this example, the height of the trapezoid is 8.4 kilometers.

In general, to find the height of a trapezoid when given the area, we need to know the values of both bases. Once we have those values, we can use the formula above to solve for the height. If we are not given the values of the bases, we cannot find the exact value of the height.

(c) if you have learned that 30 vehicles have already failed in under 2 years, what is the approximate probability that no more than 10 of the rest of them fail in their first 2 years?

Answers

a) We would expect approximately 0.2325 × 200 = 46.5 vehicles

to fail in their first 2 years. Since we cannot have a fraction of a vehicle

failing, we would expect around 46 or 47 vehicles to fail in their first 2

years.

b) The approximate probability that 50 or more vehicles fail in

the first 2 years is 0.0004.

c) The approximate probability that no more than 10 of the remaining

vehicles fail in their first 2 years, given that 30 have already failed, is 0.0002.

a) The average lifespan of the vehicle is 8 years, and it follows an

exponential distribution, which has a probability density function of

[tex]f(x) = (1/θ) \times e^(-x/θ)[/tex],

where θ is the mean of the distribution. Thus, θ = 8.

The probability that a vehicle fails in the first 2 years can be found by

integrating the exponential probability density function from 0 to 2:

P(X ≤ 2) = ∫[0,2] f(x) dx = ∫[0,2] (1/8) × e^(-x/8) dx

Using a calculator or a table of integrals, we can find this probability to

be approximately 0.2325.

b) The number of vehicles that fail in the first 2 years follows a Poisson

distribution with parameter λ = 200 × P(X ≤ 2) = 200 × 0.2325 = 46.5.

The probability that 50 or more vehicles fail in the first 2 years can be

found using the Poisson distribution with parameter λ = 46.5:

P(X ≥ 50) = 1 - P(X < 50)

Using a Poisson distribution table or a calculator, we can find that P(X <

50) is approximately 0.9996.

Thus, P(X ≥ 50) = 1 - 0.9996 = 0.0004 (approximately).

c) Given that 30 vehicles have already failed in under 2 years, we need

to find the probability that no more than 10 of the remaining 170 vehicles

fail in their first 2 years.

The number of vehicles that fail in the first 2 years follows a Poisson

distribution with parameter λ = 170 × P(X ≤ 2) = 170 × 0.2325 = 39.525

(rounded to 40).

Thus, we need to find P(Y ≤ 10), where Y is a Poisson random variable

with parameter λ = 40.

Using a Poisson distribution table or a calculator, we can find that P(Y ≤

10) is approximately 0.0002.

The total number of ways to assign the guests to the rooms is 126 ways

We can solve this problem by using a combination. We have 5 friends and 5 rooms, so we can think of the friends as stars and the rooms as bars that separate them. The number of ways to assign the friends to the rooms is equal to the number of ways to arrange the 5 stars and 4 bars (since there are 4 spaces between the bars).

We can choose any 4 positions out of 9 (5 stars and 4 bars) to place the bars, so the number of ways to assign the friends to the rooms is equal to the binomial coefficient.

mr balewa works at a bakery every Monday he uses 4 1/2 cups of flour to make six dozen cookies every Friday he makes 12 dozen cookies

Answers

In the proportion, Mr.Balewa needs  9 cups to makes 12 dozen cookies.

What is proportion?

A percentage is created when two ratios are equal to one another. We write proportions to construct equivalent ratios and to resolve unclear values. a comparison of two integers and their proportions. According to the law of proportion, two sets of given numbers are said to be directly proportional to one another if they grow or shrink in the same ratio.

Here  

He uses 4 1/2 cups of flour to make six dozen cookies then to makes 12 dozen cookies the x cups of flour .

Now using proportion,

= (4 1/2) / 6 = x / 12

= (9/2) / 6 = x/12

x = (9*12)/(2*6) = 9

= 9 cups.

Hence Mr. Balewa needs  9 cups to makes 12 dozen cookies.

please help, i cant figure this out!!​

Answers

Answer:

a = 127° , b = 12° , c = 115°

Step-by-step explanation:

a and 53° are same- side interior angles and sum to 180° , that is

a + 53° = 180° ( subtract 53° from both sides )

a = 127°

c and 115° are alternate angles and are congruent , then

c = 115°

53° , b and c lie on a straight line and sum to 180°

53° + b + c = 180°

53° + b + 115° = 180°

b + 168° = 180° ( subtract 168° from both sides )

b = 12°

then a = 127° , b = 12° , c = 115°

Answer:

a = 127; b = 12; c = 115

Step-by-step explanation:

c =115

b = 180 - 115 - 53

b = 12

a = b + c

a = 12 + 115

a = 127

Determine the values of the parameter s for which the system has a unique solution, and describe the solution.
5sx1 + 9x2 = -3
5x1 + sx2 = 4

Answers

The solution for the given system is x1 = (23/5s - x2)/4s, x2, where s ≠ -360/49 and x2 can be any non-zero

Determine the values of the parameter s?

The values of the parameter s

for which the system has a unique solution are s ≠ -45/8. Let's understand how to find the solution and the values of s:

Given equation of the system is,5x1s + 9x2 = -3 ...(1)

5x1 + sx2 = 4 ...(2)

Now, let's solve the given system of equations using the elimination method:

Multiply equation (2) by 5, we get:25x1 + 5sx2 = 20 ...(3)

Now, we'll subtract equation (1) from equation (3) as:

25x1 + 5sx2 = 20- (5x1s + 9x2 = -3)20x1 + 5sx2 = 23 ... (4)

Let's divide equation (4) by 5s, we get:

4x1 + x2/s = 23/5s ... (5)

Multiply equation (2) by 9 and subtract equation (1) from it. We get:40x2 + 9sx2 = 39

Simplifying the above equation, we get:(49s+360)x2 = 39 ... (6)

Now, we have two equations:(5) 4x1 + x2/s = 23/5s(6) (49s+360)

x2 = 39The given system of equations will have a unique solution only if x2 ≠ 0. So, let's consider the value of x2.If x2 ≠ 0, then from equation (6)

we get,49s+360 ≠ 0 or s ≠ -360/49

This means that s ≠ -360/49 is necessary for the given system to have a unique solution.

Now, let's solve the equation (5):4x1 + x2/s = 23/5s

If we multiply both sides of the equation (5)

by s, we get:

4sx1 + x2 = 23/5If x2 ≠ 0, then we can solve this equation for x1 as:

x1 = (23/5s - x2)/4s

Therefore, the solution for the given system is x1 = (23/5s - x2)/4s, x2, where s ≠ -360/49 and x2 can be any non-zero value.
