Answer:

(x, y, z) = (90, 75, 105)

Step-by-step explanation:

In a parallelogram, adjacent angles are supplementary, and opposite angles are congruent.

(x -15) +(x +15) = 180

2x = 180

x = 90

Angles y and (x-15) are opposites, so ...

y = x -15 = 90 -15 = 75

Similarly, for z ...

z = x +15 = 90 +15 = 105

The values of x, y, and z are 90, 75, and 105, respectively.

gretchen and Ezia received equal scores on a test made up of multiple choice questions and an essay. Gretchen got 18 multiple ch

timurjin [86]

The multiply choice were worth 4 points.
Gretchen= 18x+19
Ezia= 15x+31

So basically you can enter any number. At first I picked 3 and then I did the math and I got 73 points for Gretchen and 76 points for Ezia.

Then I pick four and then I got 91 points for them both. This is how I got the answer:

18x+19=15x+31
18(4)+19=15(4)+31
72+19=60+31
91=91

Suppose a bag contains many marbles, 54% of which are purple. You draw 5 marbles from the bag with replacement.

dolphi86 [110]

Part A

Use the binomial probability distribution formula.

p = 0.54 = probability of getting a purple marble

n = 5 = sample size

x = 2 = number of purple we want to get

$P(x) = \frac{n!}{x!(n-x)!}*p^x*(1-p)^{n-x}\\\\P(2) = \frac{5!}{2!(5-2)!}*0.54^2*(1-0.54)^{5-2}\\\\P(2) = 10*0.54^2*0.46^3\\\\P(2) = 0.283831776\\\\$
