a plate has a raduis of 3 inches what is the best approximation for the circumference of the plate ? use 3.14 to approimate pi.

kozerog [31]

Answer:

Best approximation for the circumference of the plate = 18.84 inches

Step-by-step explanation:

Given in the question,

radius of a plate = 3 inches

π = 3.14

To find,

circumference of the plate.

As we know that formula to calculate circumference of a circle given radius

2 (π) (3)

2 (3.14) (3)

18.84 inches

So the circumference or perimeter of area = 18.84 inches

abruzzese [7]

Not sure about the weird echo in the question but I think we're being ask to evaluate

4 - 0.25g + 0.5h

when g=10, h=5

That's

4 - 0.25(10) + 0.5(5) = 4 - 2.5 + 2.5 = 4

An experiment involves selecting a random sample of 256 middle managers at random for study. one item of interest is their mean

Nitella [24]

The standard error of the mean is 128.125.

The formula for standard error is:

$\sigma_M=\frac{\sigma}{\sqrt{N}}$

With our information, we have:

$\sigma_M=\frac{2050}{\sqrt{256}}=128.125.$

Division A reports the following data: Sales = $180,000, Net income = $18,000, Average'assets

Karolina [17]

Company A is operating more efficiently

Step-by-step explanation:

Given parameters:

Division A:

Sales = $180,000

Net income = $18,000

Average assets = $72,000

Division B:

Sales = $60,000

Net income = $9,600

Average assets = $48,000

Unknown:

Division operating more efficiently = ?

Solution:

Efficiency measures the relationship between the output from a business and the input into it. Here, the efficiency is the relationship between the net income and the average assets. it can be expressed as a percentage or ratio.

The net income is the profit derived from sales of a company's products.

The higher the value the more efficient a company is.

Efficiency = $\frac{net income}{Average assets}$ x 100

Efficiency of division A = $\frac{18000}{72000}$ x 100 = 25%

Efficiency of division B = $\frac{9600}{48000}$ x 100 = 20%

Division A has a higher efficiency compared to B
