To get the answer, you should first find the slope; its equation is 1--1/1--1 (Second y-value minus first y-value divided by second x-value minus first x-value). the slope would be 2. Now slope-intercept form is y=mx+b. We found slope which is two and for the x and y plug one of the y-value into y and one of the x-value into x. It would then be 1=2(1)+b. Solve the equation by multiplying 2 by 1 ti get 2 and divide 2 from each side. b= 1/2. b means the y-intercept.

Y= 1x+1 because 1 is the yintercept

Which complex number has a distance of √17 from the origin on the complex plane?

guapka [62]

Let the complex number be x + iy

Then by the pythagoras therem

17 = x^2 + y^2

D will satisfy this equation

4^2 + (-1)^2 = 17

answer is D 4 - i

3 in the power of ten word form

Ludmilka [50]

3 in the power of ten means "10^3."

$10^3$

How to solve exponents is to multiply the number as many times as it's exponent. So in this case you will have to multiply ten, three times.

$10\times10\times10=1000$

Which would mean that....

$10^3=1000$

The answer is 10^3.

Hope this helps.

The following list contains the average annual total returns (in percentage points) for 9 mutual funds. The mutual funds appear

VladimirAG [237]

Answer:

Mean =25.78

Median =20

Step-by-step explanation:

given that the following list contains the average annual total returns (in percentage points) for 9 mutual funds. The mutual funds appear in an online brokerage firm's "all-star" list.

40, 30, 6, 10, 30, 18, 15, 20, 36

Let us find the sum of these 9 entries

Sum = 205

a) Mean = $\frac{205}{9} =22.78$

b) Median of this data set is the middle entry after arranging in ascending order

Here it would be the 5th entry

6,10, 15, 18,20, 30, 30, 36, 40

Median = 20

Answer:

<QPR = 98.5 degrees

Step-by-step explanation:

a line = 180 degrees

7x + 4 + 9x - 40 = 180

16x - 36 = 180

16x = 216

x = 13.5

<QPR = 7x + 4 = 7(13.5) + 4 = 98.5
