Answer:

Tennessee

Step-by-step explanation:

First, let's find out how much tax he paid...

$695.49-$649.99=$45.50

We can use this to set up an equation...

x%(649.99)=45.50

We can convert x% to x/100 since any percentage is just that number over one hundred...

$\frac{x}{100}*649.99=45.50\\\\\frac{649.99x}{100}=45.50$

Multiply 100 to both sides

$649.99x=4550$

Divide both sides by 649.99

$x$\approx$6.92$

This is closest to 7 (our answers is not exact since you can only have two decimal places in money), therefore he lives in D. Tennessee

As part of the underwriting process for insurance, each prospective policyholder is tested for high blood pressure. Let X repres

xxTIMURxx [149]

Answer:

0.053

Step-by-step explanation:

This is a geometric distribution problem.

I'm geometric distribution problem,

E(X) = 1/p

Where;

E(X) is expected value and p is probability of success

Thus;

1/p = 12.5

p = 1/12.5

p = 0.08

Now, to find the probability that the sixth person tested is the first one with high blood pressure, we will use the probability formula in geometric distribution which is;

P(X = k) = qⁿ•p

q = 1 - p

q = 1 - 0.08

q = 0.92

Thus;probability that the sixth person tested is the first one with high blood pressure will be expressed as;

P(X > 5) = (0.92^(5)) × 0.08

P(X > 5) = 0.053

nikklg [1K]

Answer:

t(3u)

Step-by-step explanation:

First we have to triple (x3) u, which is what gets us 3u. Then we multiply that result by t.

This gives us: t(3u)

Remember, this problem is asking for you to write an expression, not and equation. That is why there is not an equal sign included in the answer.

How much money should be deposited today in an account that earns 8% compounded monthly so that it will accumulate to 13,000 tho

gladu [14]

Answer:

$10,234.31

Step-by-step explanation:

A suitable financial calculator or spreadsheet can evaluate the future value function for you. It will tell you that $10,234.31 must be deposited today to have $13,000 in three years, when interest is 8% compounded monthly.

You are solving for P:

13000 = P(1 +0.08/12)^(12×3)

P = 13000/(1 +0.08/12)^36 ≈ 10,234.31
