Leon charged $75 at an interest rate of 12.5%. How much will Leon have to pay after one month if he makes no payments

pav-90 [236]

I believe that the question is assuming this is taking place over one month here is what I think you would do.

1) 75/12.5 = 6
2) add that answer to 75, so 75+6, and you get 81

Find the slop from the given equation. 2x + 4y + 7 = 0

antiseptic1488 [7]

The slope of the line would be -1/2.

To find the slope we need to make the line in the form y = mx + b:

2x + 4y + 7 = 0

2x + 4y = -7

4y = -2x - 7

÷ 4

y = (-2/4)x - (7/4)

-2/4 simplifies to -1/2.

I hope this helps!

The mean annual income for adult women in one city is $28,520 and the standard deviation of the incomes is $5600. The distributi

pshichka [43]

Answer:

$E(\bar{x}) = 28520$

Standard error of mean = 689

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = $28,520

Standard Deviation, σ = $5600

Mean of sampling distribution =

$E(\bar{x}) = \mu = 28520$

As per Central Limit Theorem, if the sample size is large enough, then the sampling distribution of the sample means follow approximately a normal distribution.

Sample size, n = 66

Since the sample size is large, we can use normal distribution for approximation.

Standard error of mean =

$\displaystyle\frac{\sigma}{\sqrt{n}} = \frac{5600}{\sqrt{66}} = 689.31 \approx 689$
