Answer:

The equation is y = x + 9.

Step-by-step explanation:

We need to equation of SR

Slope = slope of UV = 3/2

= 1.

One point on SR is (-2, 7) so using the point-slope form of the equation:

y - y1 = m(x - x1)

Here m = 1, x1 = -2, y1 = 7:

y - 7 = 1(x - (-2))

y - 7 = x + 2

y = x + 9

The scores of 1000 students on a standardized test are normally distributed with a mean of 50 and a standard deviation of 5. wha
ra1l [238]
We are looking to find P(X>60 students)

X is normally distributed with mean 50 and standard deviation 5

We need to find the z-score of 60 students 
Z= \frac{60-50}{5}=2

To find the probability of P(Z>2), we can do 1 - P(Z<2)
So we read the probability when Z<2 which is 0.9772, then subtract from one we get 0.0228

The number of students that has score more than 60 is 0.0228 x 1000 = 228 students
