scoray [572]

Answer:

mean =503.75

median=400

mode=400

range=691

Step-by-step explanation:

mean= 211+351+359+400+400+659+748+902=4030/8= 503.75

range= highest number -lowest number = 902-211=691

median= 400+400 =800/2= 400

A doctor's prescription calls for a daily intake containing 50 mg of vitamin C and 10 mg of vitamin D. Your pharmacy stocks two

blagie [28]

Setup
0.8x + 0.4y = 50
0.1x + 0.2y = 10 - Multiply by -2 and add

get
0.6x = 30
x = 50 mg compound A

.1 (50) + .2y = 10
5 + .2y = 10
.2y = 5
y = 25 mg compound B

What is the slope of (-3,2) and (6,1)

evablogger [386]

Answer: -1/9

Step-by-step explanation:

Find the Slope (−3, 2) and (6, 1)

Slope is equal to the change in y over the change in x, or rise over run.

$m=\frac{change in y}{change in x}$

The change in x is equal to the difference in x-coordinates (also called run), and the change in y

is equal to the difference in y-coordinates (also called rise).

$m = \frac{y_2-y_1}{x_2-x_1}$

Substitute in the values of x and y into the equation to find the slope.

$m = \frac{1-(2)}{6-(-3)}$

Simplify the numerator. Tap for more steps...

$m=\frac{-1}{6-(-3)}$

Simplify the denominator.

$m=-\frac{1}{9}$
