Answer:
Step-by-step explanation:
we have
This is the equation of the line in point slope form
where
The slope is m=1
The point is (4,8)
Convert to slope intercept form
Isolate the variable y
Adds 8 both sides
Combine like terms
Convert to function notation
Answer:
70.56
Step-by-step explanation:
The variance is the standard deviation squared.
σ² = (8.4)² = 70.56
Answer:
x=88
Step-by-step explanation:
That third line is a transversal, making 92 and x supplementary to each other.
92+x=180
x=88
Answer:
There are 180 marbles in the jar
Step-by-step explanation:
Let x = number of marbles in the jar
x * 25% = number of red marbles
x * .25 = 45
Divide each side by .25
x *.25/.25 = 45/.25
x =180
There are 180 marbles in the jar
