Answer:
To solve an equation in which a variable is divided by a number, you use the inverse of division, multiplication, to isolate the variable and solve the equation
Step-by-step explanation:
Solve: 3x+4=-8.
x=-4
Solve: 5a+3=-37.
a=-8
Let X be the number of cell phone minutes used by high school seniors.
X follows Normal distribution with mean μ = 500 and standard deviation σ =50.
The probability that students uses between 400 and 500 minutes is
P(400 < X < 500) = ![P(\frac{400-500}{50} < \frac{x -mean}{standard deviation} < \frac{500-500}{50} )](https://tex.z-dn.net/?f=%20P%28%5Cfrac%7B400-500%7D%7B50%7D%20%20%3C%20%5Cfrac%7Bx%20-mean%7D%7Bstandard%20deviation%7D%20%3C%20%5Cfrac%7B500-500%7D%7B50%7D%20%20%29%20%20)
= P( -2 < Z < 0)
= P(Z < 0) - P(Z < -2)
= 0.5 - 0.0228
P(400 < X < 500) = 0.4772
The probability that student uses between 400 and 500 minutes is 0.4772
