Answer:

Step-by-step explanation: The mean of a dat set is equal to the sum of the set of numbers divided by how many numbers are in the set. Let's look at an example of a data set and find the mean.

Data set ⇒ 15, 24, 49, 8, 50

To find the mean of the data set shown here, let's begin by adding the numbers.

15 + 24 + 49 + 8 + 50 = 146

Now, 146 will be divided by how many numbers are in the set which is 5.

146 ÷ 5 = 29.2

Therefore, the mean of the data set shown here is 29.2.

Kaylee invested $910 in an account paying an interest rate of 2.6% compounded

Nikitich [7]

Answer:

$1,179

Step-by-step explanation:

Lets use the compound interest formula provided to solve this:

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

P = initial balance

r = interest rate (decimal)

n = number of times compounded annually

t = time

First, lets change 2.6% into a decimal:

2.6% -> $\frac{2.6}{100}$ -> 0.026

Since the interest is compounded quarterly, we will use 4 for n. Lets plug in the values now:

$A=910(1+\frac{0.026}{4})^{4(10)}$

$A=1,179.21$

The account balance after 10 years will be $1,179

Find the slope of the given line, if it is defined.

il63 [147K]

Answer: A. The slope is $-\dfrac{4}{3}$ .

Step-by-step explanation:

The slope of a line helps to specify the direction of the line.

The slope of a line that passes through (a,b) and (c,d) is given by :-

$\text{Slope}=\dfrac{d-b}{c-a}$

Then the slope of a line passes through origin i.e. (0,0) and (-9,12) is given by :-

$\text{Slope}=\dfrac{12-0}{-9-0}\\\\\Rightarrow\ \text{Slope}=\dfrac{12}{-9}\\\\\Rightarrow\ \text{Slope}=-\dfrac{4}{3}$

Hence, the slope is $-\dfrac{4}{3}$ .

Min knows that Pi times r = 9.42 centimeters. What would she need to do to find the area?

Alinara [238K]

Answer:

The area of the circle is 28.26.

Step-by-step explanation:

πr =9.42

Using that, we can find the radius, which will help us find the area of the circle.

9.42/π = 3 (I used 3.14 for π)

The formula for area of a circle is:

πr^2

Plug our values in.

π(3^2)

9π

28.26

The area of the circle is 28.26.

To sum, Min would need to first figure out the radius of the circle, and then use the radius to find the area of the circle. She can figure out the radius by dividing 9.42 by π, and find the area with the formula πr^2.
