The centroid divides each <span>median </span><span>in a </span>ratio<span> of 2:1

</span><span>A. If CY = 10, find PC and PY
PC = 2(10) = 20
PY = 10 + 20 = 30

</span><span>B. If QC = 10, find ZC and ZQ
ZC = 10/2 = 5
ZQ = 10 + 5 = 15

</span><span>C. If PX = 20 find PQ
PQ = 2(20) = 40</span>

A store has 80 modems in its inventory, 30 coming from source a and the remainder from source

Mrrafil [7]

The number of defective modems in the inventory is 20%⋅ 30 + 8%⋅ 50 = 10 (out of 80). Note that the number of defectives in the inventory is fixed, i.e., we are not told that there is 1 8 probability that a modem in the inventory is defective, but rather that exactly 1 8 of all modems are defective. The probability that exactly two modems in a random sample of five are defective is = 0.102

Give the following equations determine if the lines are parallel perpendicular or neither

GaryK [48]

In order to determine whether the equations are parallel, perpendicular, or neither, let's simply each equation into a slope-intercept form or basically, solve for y.

Let's start with the first equation.

$\frac{6x-5y}{2}=x+1$

Cross multiply both sides of the equation.

$6x-5y=2(x+1)$ $6x-5y=2x+2$

Subtract 6x on both sides of the equation.

$6x-5y-6x=2x+2-6x$ $-5y=-4x+2$

Divide both sides of the equation by -5.

$-\frac{5y}{-5}=\frac{-4x}{-5}+\frac{2}{-5}$ $y=\frac{4}{5}x-\frac{2}{5}$

Therefore, the slope of the first equation is 4/5.

Let's now simplify the second equation.

$-4y-x=4x+5$

Add x on both sides of the equation.

$-4y-x+x=4x+5+x$ $-4y=5x+5$

Divide both sides of the equation by -4.

$\frac{-4y}{-4}=\frac{5x}{-4}+\frac{5}{-4}$ $y=-\frac{5}{4}x-\frac{5}{4}$

Therefore, the slope of the second equation is -5/4.

Since the slope of each equation is the negative reciprocal of each other, then the graph of the two equations is perpendicular to each other.

15 POINTS EACH!!!~<br> Please See If You Know The Answer To Both Thank You!

valentina_108 [34]

Answer:

p(green) = 3/10

p(red) = 5/10

(you can of course reduce)

Step-by-step explanation:

Probability is just a big word for a simple concept

Probability of green marbles = number of green marbles over total number of marbles.

Probability of red marbles = number of red marbles over total number of marbles.

Don't over complicate it :)
