Answer: What is the measure of ∠ DAB?

And we get that the measure of angle is 32 degrees.

Step-by-step explanation:

Answer: -4x

Using the normal distribution, it is found that:

a) There is a 0.0228 = 2.28% probability that a randomly chosen salary exceeds $35,000.

b) There is a 0.3085 = 30.85% probability that a randomly chosen salary is less than $22,500.

c) There is a 0.4938 = 49.38% probability that a randomly chosen salary lies between $25,000 and $37,500.

d) The 15th percentile of the sociology salaries is of $19,825.

e) The salaries are $20,800 and $29,200.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem:

Item a:

The probability is 1 subtracted by the p-value of Z when X = 35000, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{35000 - 25000}{5000}[/tex]

[tex]Z = 2[/tex]

[tex]Z = 2[/tex] has a p-value of 0.9772.

1 - 0.9772 = 0.0228.

There is a 0.0228 = 2.28% probability that a randomly chosen salary exceeds $35,000.

Item b:

The probability is the p-value of Z when X = 22500, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{22500 - 25000}{5000}[/tex]

[tex]Z = -0.5[/tex]

[tex]Z = -0.5[/tex] has a p-value of 0.3085.

There is a 0.3085 = 30.85% probability that a randomly chosen salary is less than $22,500.

Item c:

This probability is the p-value of Z when X = 37500 subtracted by the p-value of Z when X = 25000, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{37500 - 25000}{5000}[/tex]

[tex]Z = 2.5[/tex]

[tex]Z = 2.5[/tex] has a p-value of 0.9938.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{25000 - 25000}{5000}[/tex]

[tex]Z = 0[/tex]

[tex]Z = 0[/tex] has a p-value of 0.5.

0.9938 - 0.5 = 0.4938

There is a 0.4938 = 49.38% probability that a randomly chosen salary lies between $25,000 and $37,500.

Item d:

This is X when Z has a p-value of 0.15, so X when Z = -1.035.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]-1.035 = \frac{X - 25000}{5000}[/tex]

[tex]X - 25000 = -1.035(5000)[/tex]

[tex]X = 19825[/tex]

The 15th percentile of the sociology salaries is of $19,825.

Item e:

Due to the symmetry of the normal distribution, it is the 20th percentile and the 80th percentile, that is, X when Z = -0.84 and X when Z = 0.84.

20th percentile:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]-0.84 = \frac{X - 25000}{5000}[/tex]

[tex]X - 25000 = -0.84(5000)[/tex]

[tex]X = 20800[/tex]

80th percentile:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]0.84 = \frac{X - 25000}{5000}[/tex]

[tex]X - 25000 = 0.84(5000)[/tex]

[tex]X = 29200[/tex]

The salaries are $20,800 and $29,200.

There's only two outcomes (true or false) and one correct answer.

Therefore, the probability is 1/2 = 0.50 = 50%

Or you could say the odds are 50 50, ie there's a 50% chance of getting it right vs a 50% chance of getting it wrong.

Reason:

Use the inscribed angle theorem. Central angle DCE subtends the arc DE, so angle DCE = 84 degrees. Inscribed angle EFD is also subtending this same arc (DE), meaning we cut the arc/central angle measure in half to get 84/2 = 42.

Answer:

Rounding up to the nearest hundredth, 907.49

Step-by-step explanation:

10% of 824.99 is 82.499 so all you have to do is 824.99 + 82.499 which will get you 907.48900 and rounding to the nearest hundreth will get you 907.49

Step-by-step explanation:

10% of 824.99 = 82.499

then 824.99 +82.499= 907.489

rounded off = 907.49

SA = 76 yd²

Step-by-step explanation:

Use the formula given:

The units are yards²

SA = 76yd²

-Chetan K

The surface area of the rectangular prism is 76 square yards

The dimensions of the rectangular prism are given as:

Length (l) = 4 yards

Width (w) = 2 yards

Height (h) = 5 yards

The surface area (SA) is calculated as:

SA =2lw + 2lh + 2wh

So, we have:

SA = 2 * 4 * 2 + 2 * 4 * 5 + 2 * 2 * 5

Evaluate the expression

SA = 76

Hence, the surface area of the rectangular prism is 76 square yards
