Mei Mei invested $1700 in an account that pays 3% interest compounded annually.

algol [13]

Answer:

$2728

Step-by-step explanation:

Use compound interest formula:

$A = P(1 + \frac{r}{n})^{nt}$

P = 1700, r = 0.03, n = 1, t = 16

Plug in numbers:

$A = 1700(1 + \frac{0.03}{1})^{(1)(16)}$

Simplify:

$A = 1700(1.3)^{16$

Use calculator:

$A = 2728$

Given that z is a standard normal random variable, find z for each situation. The area to the right of z is .1314. (Round to two

Mumz [18]

Answer:

$P(Z>0.1314) = 1-P(Z$

We can use the following excel code: "=1-NORM.DIST(0.1314,0,1,TRUE)" or the standard normal table

$P(Z$

We can use the following excel code: "=NORM.DIST(0.75,0,1,TRUE)" or the standard normal table.

$P(Z>0.01) = 1-P(Z$

We can use the following excel code: "=1-NORM.DIST(0.01,0,1,TRUE)" or the standard normal table

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Solution to the problem

$P(Z>0.1314) = 1-P(Z$

We can use the following excel code: "=1-NORM.DIST(0.1314,0,1,TRUE)" or the standard normal table

$P(Z$

We can use the following excel code: "=NORM.DIST(0.75,0,1,TRUE)" or the standard normal table.

$P(Z>0.01) = 1-P(Z$

We can use the following excel code: "=1-NORM.DIST(0.01,0,1,TRUE)" or the standard normal table

Your school raised 125% of its fundraising goal. The school raised $6750. What was the goal?

lozanna [386]

Let, the Goal = x
It would be: x * 125% = 6750
x * 1.25 = 6750 [ 125% = 1.25]
x = 6750 / 1.25
x = 5400

In short, Your Answer would be $5400

Hope this helps!

Select the relations that are functions.

liraira [26]

Answer:

option A, C and D

Step-by-step explanation:

Each relation is a function if each input has only one output

{a, 1), (6, 1), (C, 1)

This relation is a function because each input has only one output

{a, a),(a, b),(a, c)}

This relation is not a function because input 'a' has only three output

{(1, a), (2, a),(3, a)}

This relation is a function because each input has only one output

{a, a), (b, b), (C, c)}

This relation is a function because each input has only one output
