Answer:
A. The y-intercept is 8 and the slope is 
.
Step-by-step explanation:
We have been given graph of line of best fit. We are asked to find the y-intercept and slope of our given line.
We know that y-intercept of a graph is the point, where line intersects y-axis. upon looking at our given graph, we can see that our line touches y-axis at point (0,8), therefore, y-intercept is 8.
Let us find slope of our given line using points 
as:
Therefore, the slope of our given line is and option A is the correct choice.
Answer:
y=61, x=112
Step-by-step explanation:
119+y=180
180-119=y
61=y
131+56+61+x=360
248+x=360
360-248=x
112=x
Answer:
113.1

C=2πr
Answer: 50 %
Step-by-step explanation: 4/8 is 50% and 1/2 is 50% so it is a 50% chance
Answer:
<u>Height = 3 inches and Base length = 7 inches</u>
Step-by-step explanation:
1. Information provided to answer the question correctly:
Base of the triangle = x+ 4
Height of the triangle = x
Area of the triangle = 10.5 inches²
2. Find the base length and height
Let's recall the formula of the area of a triangle:
Area = (Base * Height)/2
Replacing with the values we know:
10.5 = x (x + 4)/2
21 = x² + 4x
x² + 4x - 21 = 0
(x + 7) (x - 3) = 0
(x₁ + 7) = 0 ⇒ x₁ = -7
(x₂ - 3) = 0 ⇒ x₂ = 3
We take x₂ as the answer because x₁ = -7 is not a valid height.
<u>Height = 3 inches and Base length = 7 inches</u>
