5.2+4.8= 10
So it has to be 20 I think
Answer:
A) N + Q = 9
B) .05 N + .25 Q = 1.45
Multiplying A) by -.25 we get
A) -.25 N -.25Q = -2.25 then adding B)
B) .05 N + .25 Q = 1.45
-.2N = -.80

Answer:
Step-by-step explanation:
we know that
The height of Justin’s rocket is modeled by the equation
This is the equation of a vertical parabola open downward
The vertex is a maximum
where
The coefficient of t^2 represent the acceleration
The coefficient of t represent the initial velocity
The constant of the equation represent the initial height
Remember that
Elena launched his rocket from the same position, but with an initial velocity double that of Justin’s
so
Now the initial velocity is
substitute
The height of Elena’s rocket is the equation
Answer:
Median: 52
Mode: 52
Explanation:
The mode is the element that occurs most in the data set.
Arrange the data in ascending order and the median is the middle value. If the number of values is an even number, the median will be the average of the two middle numbers.
