Rochelle deposits $5,000 in an IRA. What will be the value of her investment in 25 years if the investment is earning 8% per yea

Iteru [2.4K]

Answer:

$\$36,945.28$

Step-by-step explanation:

we know that

The formula to calculate continuously compounded interest is equal to

$A=P(e)^{rt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

e is the mathematical constant number

we have

$t=25\ years\\ P=\$5,000\\ r=8\%=8/100=0.08$

substitute the values in the formula

$A=5,000(e)^{0.08*25}$

$A=5,000(e)^{2}$

$A=\$36,945.28$

Step-by-step explanation:

The supervisor is asking for an expense form of a <u>total (?) </u>when you return.

Given the charges given in the word problem, it is only logical to assume the supervisor wants a expense form of how much you spent (total) on the trip. Thus, you add!

Carl scored 32 on the ACT mathematics Test and 730 on the mathematics portion of the SAT. If the ACT Math Test had a mean score

Shtirlitz [24]

Answer:

Carl's ACT grade had a higher z-score, which means that he earned a better score with respect to his peers on the ACT test.

Step-by-step explanation:

Z-score

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

On which exam did Carl earn a better score with respect to his peers?

On whichever exam he had the higher z-score.

SAT

Scored 730, mean 516, standard deviation 116. So

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{730 - 516}{116}$

$Z = 1.84$

ACT

Scored 32, mean 21, standard deviation 5.3. So

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{32 - 21}{5.3}$

$Z = 2.08$

Carl's ACT grade had a higher z-score, which means that he earned a better score with respect to his peers on the ACT test.

Isaac had lots of candy. He ate the same number of pieces each day, and the amount remaining can be modeled by the equation y =

zlopas [31]

Answer:

1. he eats 5 per day (5 less every day)

2. he starts with 83 pieces of candy

3. 53

4. on day 11

Step-by-step explanation:

1. self explanatory

2. self explanatory

3. 6*-5=-30 -30+83=53

4. put y as 28

28=-5x + 83 now solve for x

subtract 83 both sides

-55=-5x

divide -5 from both sides

11=x
