Suppose that X has the normal distribution for which the mean is 1 and the variance is 4. Find the value of each of the following probabilities: a. Pr(X ≤ 3)
b. Pr(X > 1.5)
c. Pr(X = 1)
d. Pr(25)
e. Pr(X ≥ 0)
f. Pr(−10.5)
g. Pr(|X| ≤ 2)
h. Pr(1≤−2X + 3 ≤ 8)

Use the quadratic formula to solve the equation. if necessary, round to the nearest hundredth. x^2 - 8 = -6x a. –7.12, 1.12 b. 7.12, –1.12 c. 7.12, 1.12 d. –7.12, –1.12

Wich statement could be used to explain why the function h(x)= x^3 has an inverse relation that is also a function

Ms.ortiz sells tomatoes wholesale. the function p(x)=-80x^2+320x-10, graphed below, indicates how much profit she makes on a load of tomatoes if she makes on a load of tomatoes if she sells them for 4-x dollars per kilogram. what should ms.ortiz charge per kilogram of tomatoes to make on a load of tomatoes?
