Answer:

angle 1: 51 angle 3: 123, angle 2: 18, angle 4: 39

Step-by-step explanation:

First lets find angle 1: We can see that the triangle already has 2 angles filled in, so remember that triangles are 180 degrees total. Now we take 72+57=129 degrees. Now 180-129=51 degrees that were missing.

Angle 3: angle 57 and angle 3 will add up to 180 degrees, because it is a line. So all we need to do is subtract 180-57=123 degrees.

Angle 2: We see that there is a right angle on that corner, so we already have 72 degrees. Take 90-72= 18 degrees.

Angle 4: We know angles 3 and 2, so add them up: 123+18=141. Triangles add up to 180 degrees, so 180-141=39 degrees for the missing angle.

Naya [18.7K]

An example for #1 would be that: 15 is divisible by 3, but not 9. every third multiple of 3, (9, 18, 27,...) is divisible by 9 because 9 is three times the size of 3.

For part two the first number that I thought of is 23.

HELP A line passes through two points with coordinates (6,-8) and (-3,7).
FromTheMoon [43]

Answer:

<em>3y+5x=6</em>

Step-by-step explanation:

<u>Equation of the Line</u>

The equation of a line passing through points (x1,y1) and (x2,y2) can be found as follows:

\displaystyle y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)

The line passes through the points (6,-8) and (-3,7), thus:

\displaystyle y+8=\frac{7+8}{-3-6}(x-6)

\displaystyle y+8=\frac{15}{-9}(x-6)

Simplifying:

\displaystyle y+8=-\frac{5}{3}(x-6)

Multiplying by 3:

3(y+8)=-5(x-6)

3y+24=-5x+30

Moving all the variables to the left side:

3y + 5x = 30 - 24

3y + 5x = 6

Debora [2.8K]

Answer:

a) 0.0885 = 8.85% probability that the mean annual return on common stocks over the next 40 years will exceed 13%.

b) 0.4129 = 41.29% probability that the mean return will be less than 8%

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the z-score of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean \mu and standard deviation \sigma, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \mu and standard deviation s = \frac{\sigma}{\sqrt{n}}.

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Mean 8.7% and standard deviation 20.2%.

This means that \mu = 8.7, \sigma = 20.2

40 years:

This means that n = 40, s = \frac{20.2}{\sqrt{40}}

(a) What is the probability (assuming that the past pattern of variation continues) that the mean annual return on common stocks over the next 40 years will exceed 13%?

This is 1 subtracted by the pvalue of Z when X = 13. So

Z = \frac{X - \mu}{\sigma}

By the Central Limit Theorem

Z = \frac{X - \mu}{s}

Z = \frac{13 - 8.7}{\frac{20.2}{\sqrt{40}}}

Z = 1.35

Z = 1.35 has a pvalue of 0.9115

1 - 0.9115 = 0.0885

0.0885 = 8.85% probability that the mean annual return on common stocks over the next 40 years will exceed 13%.

(b) What is the probability that the mean return will be less than 8%?

This is the pvalue of Z when X = 8. So

Z = \frac{X - \mu}{s}

Z = \frac{8 - 8.7}{\frac{20.2}{\sqrt{40}}}

Z = -0.22

Z = -0.22 has a pvalue of 0.4129

0.4129 = 41.29% probability that the mean return will be less than 8%
