There are three executives in an office, ages 56, 57, and 58. If a 57-year-old executive enters the room, the

Answer:

option (c) The mean age will stay the same but the variance will decrease

Step-by-step explanation:

Case I: For 3 executives of ages 56, 57 and 58

Number of executives, n = 3

Mean = $\frac{\textup{56 + 57 + 58 }}{\textup{3}}$

Mean = 57

Variance = $\frac{\sum{(Data - Mean)^2}}{\textup{n-1}}$

Variance = $\frac{(56 - 57)^2+(57-57)^2+(58-57)^2}{\textup{3-1}}$

Variance = $\frac{1+0+1}{\textup{2}}$

Variance = 1

For Case II: For 4 executives of ages 56, 57, 58 and 57

Number of executives, n = 4

Mean = $\frac{\textup{56 + 57 + 58 + 57 }}{\textup{4}}$

Mean = 57

Variance = $\frac{\sum{(Data - Mean)^2}}{\textup{n-1}}$

Variance = $\frac{(56 - 57)^2+(57-57)^2+(58-57)^2+(57-57)^2}{\textup{4-1}}$

Variance = $\frac{1+0+1+0}{\textup{3}}$

Variance = 0.67

Hence,

Mean will remain the same and the variance will decrease

Hence,

The correct answer is option (c) The mean age will stay the same but the variance will decrease

Joey works 20 hours a week. If he works for 10 months continually, how many hours will he have worked? (1 month = 4 weeks)

Tcecarenko [31]

800 because 20*4*10=800 which means he works 80 weeks a month for 10 months

Which special version of the Pythagorean Theorem can you use to find the length of any squares diagonal, d, using only the lengt

EleoNora [17]

The square's diagonal is the triangle's hypotenuse.

The Pythagorean theorem is = $a^{2}+b^{2}=c^{2}$

Here, 'c' is the hypotenuse and 'a' and 'b' are the two sides of the triangle.

As the side is given 12 inches, so this becomes

$12^{2}+12^{2}=d^{2}$

$144+144=d^{2}$

$d^{2}=288$

$d=\sqrt{288}$

$d=16.97$ inches
