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

vova2212 [387]

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

or

Mean = 57

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

or

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

or

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

or

Variance = 1

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

Number of executives, n = 4

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

or

Mean = 57

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

or

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

or

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

or

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

Mr. Smith offered to stay after school for an extra help session. The day after the

marissa [1.9K]

Answer:

132 students

Step-by-step explanation:

Mr Smith offers to take extra help session for students after school

The day after the help session 11 of his students were talking and found out that only 2 had stayed up for the help session

= 2/11

There were actually a total number of 24 students that stayed

We are asked to find the number of student that Mr Smith teaches throughout the day

Let x represent the number of students that were taught during the day

Therefore, the number of student that Mr Smith teaches during the day can be calculated as follows

2/11=24/x

Cross multiply both sides

2 × x = 24 × 11

2x= 264

Divide both sides by 2

2x/2=264/2

x= 132

Hence Mr Smith teaches 132 students during the day.
