Original price $45.00; markdown 22%

1 answer:

4 0

First convert 22 to decimal form. You do this by dividing the percent by 100.
22 / 100 = .22

Then multiply the dollar amount by the percentage in decimal form.

$45 * .22 = $9.9

So 22% of $45 is $9.9.

Then you subtract $9.9 from $45.

$45 - $9.9 = $35.1

Currently a product has a gear ratio of 17:5, driver:driven. If the company wants to change the product to have the same gear ra

Sedbober [7]

Answer:

10 teeth must go on the driven gear

Step-by-step explanation:

Let the number of teeth be x

In order for the new product to maintain the same ratio as the old the ratio must remain the same. This means that

17:5 = 34:x

$\frac{17}{5} = \frac{34}{x}\\Now\ let\ us\ cross-multiply\\17 \times x = 5 \times 34\\17x = 170\\dividing\ both\ sides\ by\ 17 \\x = \frac{170}{17} \\x = 10$

∴ 10 teeth must go on the driven gear

hence ratio = 34:10

MATH HELP!?

Debora [2.8K]

The correct answers are: 
1) C
2) A
3) D

Explanation: 
1) Voluntary deductions are amounts that you elect to come out of your paycheck every pay period. Federal tax is not voluntary; neither is state tax, nor Social Security. The only voluntary deduction in this list is health insurance. You are not obligated to pay for your health insurance by automatically withholding it from your check.

2) FICA is the tax that goes towards Social Security and Medicare. It is involuntary, and it is deducted as a percentage of your gross (pre-withholding) pay.

3) A fixed expense would be one that is the same from month to month. The only one of these expenses that would be the same amount monthly is a mortgage.

Suppose a normal distribution has a mean of 48 and a standard deviation of 2. What is the probability that a data value is betwe

stepan [7]

Answer:

Choice D. 15.2%

Step-by-step explanation:

We have a normal...

mean u = 48

standard deviation s = 2

We want P(43 < X < 46)

We standardize.

Consider P(43 < X) = P( (43 - 48)/2 < Z) = P(-2.5 < Z)

P( X < 46) = P( Z < (46 - 48)/2 ) = P(Z < -1)

We want P( -2.5 < Z < -1)

Look at Z-scores.

P( Z < -2.5) = 0.0062

P(Z < -1) = 0.1587

so P(-2.5 < Z < -1) = P(Z < -1) - P(Z < -2.5) = 0.1587 - 0.0062 = 0.1525 = 15.2%
