Emily and her twin sister Erica were each given $500 for their birthday. Emily deposits her money in an account that pays 4.75% interest compounded annually. Erica deposits her money in a 5% simple annual interest account. After 10 years how much more money will Emily have in her account?
A $22.41
B $45.26
C $250.00
D $295.26

Answers

Answer:

B $45.26

Step-by-step explanation:

After 10 years

Emily will have 500 * 1.045^10 = $795.26

Erica will have 500 + 10*0.05*500 = 500 * 1.5 = 750$

Emily will have $45.26 more.

A backpack is on sale for $51.00. This is 75% of the original price. What was the original price?

Answers

Original price= $204.

100%-75%= 25% or 0.25.

51 = 0.25 * n (original price)

Divide 0.25 on both sides

51/0.25 = 204

N=204

That is indeed a very expensive backpack.

O g(x) = 35-4;> 0

Answers

The answer choice which correctly describe s the function g (x) for a restricted domain as required to be determined in the task content is; g (x) = ³√(x + 4) , x ≥ -4.

Which function correctly represents the function g (x) for a restricted domain?

As evident in the task content, the function which correctly represents the function g (x) for a restricted domain is to be identified.

By observation of the function;

g (x) = ³√(x + 4) , x ≥ -4.

As evident in the task content; the lowest value of g(x) is; 0.

By checking; when x = -4; the corresponding value of g (x) is;

g (-4) = ³√(-4 + 4)

g (-4) = 0.

On this note, the required function is; g (x) = ³√(x + 4) , x ≥ -4.

Step-by-step explanation:

A company that produces white bread is concerned about the distribution of the amount of sodium in its bread. The company takes a simple random sample of 100 slices of bread and computes the sample mean to be 103 milligrams of sodium per slice. Construct a 99% confidence interval for the unknown mean sodium level assuming that the population standard deviation is 10 milligrams.

Answers

Answer:

The 99% confidence interval for the unknown mean sodium level is between 100.42 milligrams of sodium per slice and 105.58 milligrams of sodium per slice.

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.99}{2} = 0.005[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.005 = 0.995[/tex], so Z = 2.58.

Now, find the margin of error M as such

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

[tex]M = 2.58\frac{10}{\sqrt{10}} = 2.58[/tex]

The lower end of the interval is the sample mean subtracted by M. So it is 103 - 2.58 = 100.42 milligrams of sodium per slice.

The upper end of the interval is the sample mean added to M. So it is 103 + 2.58 = 105.58 milligrams of sodium per slice.

The 99% confidence interval for the unknown mean sodium level is between 100.42 milligrams of sodium per slice and 105.58 milligrams of sodium per slice.
