Answer: The average speed is 3 mph.
Step-by-step explanation:
You would divide the distance by the amount of time it would take to get there. So in this case,
1.5/0.5=3
Answer:
at 0 the amount is 5
1 is 7.5
2 is 10
3 is 12.5
the initial value is the y intercept when the value ox x=0
the initial value is 5
the rate of change is the total change of a function of the out put (y) divided by the change of the input (x)
f(x2)-f(x1)/x2-x1
10-7.5/2-1
2.5/1=2.5
or m=y2-y1/x2/x1=10-7.5/2-1=2.5
y=2.5x+5
Answer:
The first answer choice.
Step-by-step explanation:
The scatterplot has both points (2,2) and (3,2) and the other options do not include the choices.
Answer:
(1) 0.4207
(2) 0.7799
Step-by-step explanation:
Given,
Mean value,
Standard deviation,
(1) P(X ≥ 17.5) = 1 - P( X ≤ 17.5)
( By using z-score table )
= 0.4207
(2) P(14 ≤ X ≤ 18) = P(X ≤ 18) - P(X ≤ 14)
= 0.9918 - 0.2119
= 0.7799
The answer is c.
-5(2x-10)=
Distribute
-10x+50
-10(x-5)= -10x+50
