Given circle O, angle A has a measure of 36° and the radius is 10 cm, find the area of sector BOC.

Fed [463]

Answer:

The area of the sector BOC is A' = 31.4 $cm^{2}$

Step-by-step explanation:

Radius of the circle = 10 cm = 0.1 m

Angle of sector $\theta$ = 36°

Area of the circle A = $\pi r^{2}$

A = 3.14 × $0.1^{2}$ = 0.0314 $m^{2}$

Now area of the sector BOC is

$A' = A (\frac{\theta}{360} )$

$A' = 0.0314 (\frac{36}{360} )$

A' = 0.00314 $m^{2}$ = 31.4 $cm^{2}$

Therefore the area of the sector BOC is A' = 31.4 $cm^{2}$

Suppose the time it takes for a purchasing agent to complete an online ordering process is normally distributed with a mean of 8

Luba_88 [7]

Answer: 0.4

Step-by-step explanation:

We know that the standard deviation of the sampling distribution of mean is given by:-

$\sigma_x=\dfrac{\sigma}{\sqrt{n}}$

Given : Standard deviation : $\sigma= 2\text{ minutes}$

Sample size : n= 25

Then, the standard deviation of the sampling distribution of mean times will be :-

$\sigma_x=\dfrac{2}{\sqrt{25}}\\\\\Rightarrow\ \sigma_x=\dfrac{2}{5}=0.4$

Hence, the standard deviation of the sampling distribution of mean times=0.4

a plumber uses the expression 48+25h to determine the number of dollars to charge each customer. If h=4, how much does the custo

Elis [28]

Answer:

$148

Step-by-step explanation:

We are given the expression:

48+25h

We are also given h=4. Since we know what h is equal to, we can substitute 4 in for h.

48 + 25h (h=4)

48 + 25(4)

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition and Subtraction.

First, multiply 25 and 4.

48+ (25*4)

48+100

Next, add 48 and 100

48+100

148

The customer will have to pay $148
