a) Approximately 29.50% of brake pads will contain less than 32.5% copper. b)  The approximate distribution of the sample mean copper percentage is a normal distribution with mean 34 and standard error 0.7.

a)To solve this problem, we can use the z-score formula to standardize the value of 32.5 using the mean and standard deviation given:

z = (x - μ) / σ

where x is the value we are interested in (32.5), μ is the mean (34), and σ is the standard deviation (2.8).

Substituting these values, we get:

z = (32.5 - 34) / 2.8 = -0.536

Using a standard normal distribution table or calculator, we can find the probability of a z-score less than -0.536, which is approximately 0.2950 or 29.50%. Therefore, approximately 29.50% of brake pads will contain less than 32.5% copper.

b) The sample mean copper percentage of 16 pads will also follow an approximate normal distribution with mean μ = 34 and standard deviation σ/√n = 2.8/√16 = 0.7, where n is the sample size.

Therefore, the approximate distribution of the sample mean copper percentage can be expressed as:

X ~ N(34, 0.7)

where X is the sample mean copper percentage.

The mean of this distribution is equal to the population mean μ, which is 34. The standard error of the mean (also known as the standard deviation of the sampling distribution) is given by σ/√n, which is 0.7 in this case.

The rate of decrease of the side of the cube with a side of 6 cm is 0.25 cm per second.

The rate of decrease of the side of an ice cube can be calculated by considering the volume of the cube. The volume of the cube is decreasing at a rate of 1.5 cm3 per second. Therefore, the rate of decrease of the side of the cube is proportional to the cube's volume.

To calculate the rate of decrease of the side of the cube, we need to use the formula for the volume of a cube, which is: V = s3, where V is the volume and s is the side of the cube.

Since we know that the volume of the cube is decreasing at a rate of 1.5 cm3 per second, we can calculate the rate of decrease of the side of the cube by substituting the value of the rate of decrease of the volume and the current side of the cube (6 cm) into the formula.

Therefore, the rate of decrease of the side of the cube is equal to 1.5 cm3 per second divided by 6 cm3, which is equal to 0.25 cm per second.

In conclusion, the rate of decrease of the side of the cube with a side of 6 cm is 0.25 cm per second.

The coordinates for the dilated triangle is obtained as A'(-1, 8), B'(-7, 6), and C'(-7, -4).

What is dilation?

Resizing an item uses a transition called dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. The initial shape should be stretched or contracted during a dilatation.

The coordinates point of the triangle is given as -

A (-1,6)

B (-4,5)

C (-4,0)

To dilate triangle ABC by a scale factor of 2 about the point (-1, 4), we can follow these steps -

Translate the triangle so that the center of dilation is at the origin.

We can do this by subtracting (-1, 4) from each vertex -

A' = (-1, 6) - (-1, 4) = (0, 2)

B' = (-4, 5) - (-1, 4) = (-3, 1)

C' = (-4, 0) - (-1, 4) = (-3, -4)

Dilate the translated triangle by multiplying the coordinates of each vertex by the scale factor of 2 -

A'' = 2(0, 2) = (0, 4)

B'' = 2(-3, 1) = (-6, 2)

C'' = 2(-3, -4) = (-6, -8)

Translate the dilated triangle back to its original position by adding (-1, 4) to each vertex -

A'B'C' = A'' + (-1, 4) = (-1, 8)

B'' + (-1, 4) = (-7, 6)

C'' + (-1, 4) = (-7, -4)

Therefore, the coordinates of the dilated triangle A'B'C' are (-1, 8), (-7, 6), and (-7, -4).

If triangles 1 and 2 are similar, the ratio relates a side length of triangle 1 to the corresponding side length of triangle 2 is 2:3.

Since Triangles 1 and 2 are similar, their corresponding sides are proportional. This means that the ratio of the length of any corresponding pair of sides in the two triangles will be equal.

To determine the ratio of the side lengths of triangle 1 to the corresponding side lengths of triangle 2, we can choose any two corresponding sides and divide their lengths.

Let's choose side AC of triangle 1 and side DF of triangle 2. We know that these two sides are corresponding because they are both opposite angles that have the same measure.

The length of side AC in triangle 1 is given as 17, and the length of side DF in triangle 2 is given as 25.5. Therefore, the ratio of the length of side AC to side DF is:

AC/DF = 17/25.5 = 0.6667 or 2/3

So the ratio of the length of a side in triangle 1 to the corresponding side in triangle 2 is 2:3. This means that if we multiply any side length in triangle 1 by 2, we will get the length of the corresponding side in triangle 2.

The winner of the election got 26320 votes.

Let's first find the total number of votes cast in the election. We know that 2/3 fraction of the electors voted for the first candidate and 1/4 of the electors voted for the second candidate. Therefore, the remaining 1/12 of the electors voted for the third candidate. So, we have:

2/3 + 1/4 + 1/12 = 8/12 + 3/12 + 1/12 = 12/12 = 1

This means that all the electors voted, and the total number of votes cast is equal to the total number of electors.

Now, let's find the number of votes the third candidate got, which is 1/12 of the total number of votes. We know that this is equal to 3290. So, we have

1/12 x Total Number of Votes = 3290

Multiplying both sides by 12, we get:

Total Number of Votes = 3290 x 12 = 39480

Now, we can find the number of votes the first candidate got, which is 2/3 of the total number of votes. We have:

It took 5 seconds for the thunder to be heard, the lightning was 343 * 5 = 1715 meters away.

The distance between the lightning flash and hearing the thunder can be calculated using the speed of sound. The speed of sound in air at 20°C is 343 meters/second.

Explanation: When lightning strikes, the initial flash travels at the speed of light, which is 299,792,458 meters per second. The sound wave created by the flash, however, travels at a much slower speed.

The speed of sound in air at 20°C is 343 meters per second.

To calculate the distance of the lightning, we multiply the speed of sound by the amount of time it took to hear the thunder. In this case, the amount of time was 5 seconds, so the lightning was 1715 meters away (343 * 5 = 1715).

To determine the sample size needed to compute the 90% confidence interval for the population proportion with a margin of error of 0.08, we can use the formula:

n = (z^2 * p * (1 - p)) / E^2

where n is the sample size needed, z is the z-score for the desired confidence level (90% confidence level has a z-score of 1.645), p is the estimated proportion (since no prior estimate is available, we use 0.5 as a conservative estimate), E is the margin of error (0.08)

Substituting the given values, we get:

n = (1.645^2 * 0.5 * (1 - 0.5)) / 0.08^2

n = 180.99

Rounding up to the nearest whole number, we get:

A correlation coefficient of 21.34 is an impossible value.

In statistics, correlation is defined as the degree of association between two or more variables. Correlation research helps to establish whether a relationship exists between two variables, and if so, to what extent. The correlation coefficient is a statistical measure used to quantify the degree of association between two variables.

The correlation coefficient, which ranges from -1 to +1, indicates the strength of the relationship between the two variables. When the correlation coefficient is 0, it indicates that there is no correlation between the two variables. When the correlation coefficient is positive, it indicates that the two variables are directly related, whereas when the correlation coefficient is negative, it indicates that the two variables are inversely related.

In this case, a correlation study reported a linear correlation coefficient of 21.34, which is not possible. Correlation coefficients range from -1 to +1. The value of the correlation coefficient ranges from -1 to +1, where a value of 0 indicates no correlation, a value of 1 indicates perfect positive correlation, and a value of -1 indicates perfect negative correlation. Therefore, a correlation coefficient of 21.34 is an impossible value.

In this case, it is likely that the correlation coefficient was misreported or that a different statistical measure was used. It is important to carefully examine and verify statistical findings before drawing any conclusions or making decisions based on the results.

where A is the final amount, P is the principal amount (initial investment), e is the constant 2.71828..., r is the annual interest rate as a decimal, and t is the time in years.

In this case, we want to solve for the initial investment P, given that the teacher wants to retire with at least $125,000 in the account after 40 years, and the annual interest rate is 6.95% compounded continuously. Therefore, we have:

A = $125,000

r = 0.0695 (annual interest rate as a decimal)
