Kareem stepped to the free throw line for two shots. if the probability of making each shot is 3/4,what is the probability that

EastWind [94]

To calculate the probability of making both shots you will multiply the probability of making .one by the same probability.

3/4 x 3/4 = 9/16

The probability of Kareem making both shots is 9/16.

Solve -3x=2x^2-4 using quadratic formula

frozen [14]

Answer:

$x=-2.35078, 0.850781$

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I

Standard Form: ax² + bx + c = 0
Quadratic Formula: $x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}$

Step-by-step explanation:

Step 1: Define equation

-3x = 2x² - 4

Step 2: Rewrite into Standard Form

0 = 2x² + 3x - 4

Step 3: Define variables

a = 2

b = 3

c = -4

Step 4: Find x

Substitute: $x=\frac{-3\pm\sqrt{3^2-4(2)(-4)} }{2(2)}$
Evaluate: $x=\frac{-3\pm\sqrt{9-4(2)(-4)} }{2(2)}$
Multiply: $x=\frac{-3\pm\sqrt{9+32} }{4}$
Add: $x=\frac{-3\pm\sqrt{41} }{4}$
Evaluate: $x=\frac{-3\pm6.40312}{4}$
Evaluate: $x=-2.35078, 0.850781$

And we have our final answer!
