Suppose that 950 couples each have a baby find the mean and standard deviation for the number of boys in the 950 babies

Mathematics

The mean and standard deviation for the number of boys in the 950 babies are 475 and 15.41, respectively

<h3>How to determine the mean and the standard deviation?</h3>

From the complete question, we have:

P(boy)= 0.5

Sample size = 950

The mean is then calculated as:

\bar x = np

This gives

\bar x = 950 * 0.5

Evaluate

\bar x = 475

The standard deviation is calculated as:

\sigma = \sqrt{np(1 - p)

This gives

\sigma = \sqrt{950 * 0.5(1 - 0.5)

Evaluate

\sigma = 15.41

Hence, the mean and standard deviation for the number of boys in the 950 babies are 475 and 15.41, respectively

  • b. 9 and -4
  • c. -7 and 3
  • d. 5 and 2
  • e. -7 and -4
  • f. 7 and 9

<h3>What numbers are required?</h3><h3 />

The question requires two numbers that can be added to get the first number and multiplied to get the second.

When 4 and 2 are multiplied, they get 8 and when added they get 6.

When 9 and -4 are added, they get 5 and when multiplied they get 36.

When -7 and 3 are multiplied, they get -21 and when added they get -4.

When 5 and 2 are added, they get 7 and when multiplied they get 10.

When -7 and -4 are multiplied, they get 28 and when added they get -11.

When 7 and 9 are added, they get 16 and when multiplied they get 63.

What is the measure of angle b
ArbitrLikvidat [17]

Answer:

(C) 102 degrees

Step-by-step explanation:

All angles in a triangle must add up to 180 degrees. If you know 2 angles, you must know the last one by subtracting the other two from 180. If you subtract 50 and 28, the two known angles in this situation, from 180, you get 102. Therefor, the last angle must be 102 degrees, or choice C.
