Total number of times rolled = 360
Total number of 2s and 3s = 31 + 49 = 80
P(2 or 3) = 80/360 = 2/9 = 0.22 (nearest hundredth)
Answer: 0.22
Answer:
3 inches up per foot across
Step-by-step explanation:
The rate of change:
( y2 - y1 ) / (x2 - x1) = ( 18 in - 12 in ) / ( 6 ft - 4 ft ) =
= 6 in / 2 ft = 3 in / 1 ft
Answer:
x=-1,-2
Step-by-step explanation:
Multiply the given equation with (x+1) on both sides. We'll get,
x+2/x=-3
or,x^2+2=-3x
or,x^2+3x+2=0
or,x^2+2x+x+2=0
or,x(x+2)+1(x+2)=0
or,(x+2)(x+1)=0
or,x=-2,-1
Answer:

x= 8 , -3
<h3>What is Quadratic Equation?</h3>
Given:
x² - 5x -24 =0
x² - 8x + 3x -24=0
x(x-8) + 3(x- 8)=0
(x-8)(x+3)=0
x= 8 , -3
