slope = (y2-y1)/(x2-x1)

1/4 = (y--1)/(6-10)

1/4 = (y+1)/(-4)

multiply by -4 on each side

-1 = y+1

subtract 1 from each side

-2 = y

The probability that a randomly selected score is greater than 334 will be 0.02275.

<h3>What is a normal distribution?</h3>

The Gaussian Distribution is another name for it. The most significant continuous probability distribution is this one. Because the curve resembles a bell, it is also known as a bell curve.

The z-score is a statistical evaluation of a value's correlation to the mean of a collection of values, expressed in terms of standard deviation.

The GRE is an entrance exam that many students are required to take in order to apply to graduate school. In 2014, the combined scores for the Verbal and Quantitative sections were approximately normally distributed with a mean of 310 and a standard deviation of 12.

Then the probability that a randomly selected score is greater than 334 will be

The z-score is given as

z = (x - μ)/σ

z = (334 - 310)/12

z = 24/12

z = 2

Then the probability will be

P(x > 334) = P(z > 2)

P(x > 334) = 1 - P(x<334)

P(x > 334) = 1 - 0.97725

P(x > 334) = 0.02275

More about the normal distribution link is given below.

I will show you how to do the first one.....we are finding the GCF...the largest number that goes into each number (same for variables)

1.)  20yx , 80x³  ( factor each number and variable)

20  =  2, 4, 5, 10, 20
y    =  y
x     =  x
80  =  2, 4, 5, 8, 10, 16, 20, 40, 80
x³  =  x, x, x

what is the largest number that 20 and 80 have in common?    20...
how about the variables?    x

so, the Greatest Common Factor (GCF is 20x)
