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

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

Answer:

We will split the trapezoid into right angle triangle and rectangle

Traingle with base 3cm and height 10 - 6 = 4cm

Area of traingle

= $\frac{1}{2}*base *height = \frac{1}{2} * 3 * 4 = 6cm^{2}$

Area of rectangle with sides 6cm and 3cm

= $6 * 3 = 18cm^{2}$

Therefore, area of the trapezoid

= $6+18 = 24cm^{2}$

Area of the semi circle with radius 3/2 = 1.5cm

= $\frac{1}{2}\pi r^{2} = \frac{1*\pi *1.5*1.5}{2} = 1.125\pi cm^{2}$

$Total area = 24 + 1.125\pi =27.53cm^{2}$

Israel added $120 to his savings. This added amount represents 1/6 of his total savings. If s represents the total savings, whic

oee [108]

Calculista Ambitious

the correct question in the attached figure

Let

s----------> total savings

case a) Israel added $80 to his savings

we know that

80=(1/8)*s-------> multiply by 8 both sides------> s=$640

the answer case a) is

the equation is

80=(1/8)*s

case b) Israel added $120 to his savings

we know that

120=(1/8)*s-------> multiply by 8 both sides------> s=$960

the answer case b) is

the equation is

120=(1/8)*s
