On an exam, Mafuyu scored in the 20th percentile. If there were 50 students in the class, how many students scored lower than he
Reptile [31]

Using the percentile concept, it is found that 10 students scored lower than he did.

<h3>What is the meaning of the percentile of a measure?</h3>

When a measure is in the xth percentile of a data-set, it is greater than x% of the measures and lesser than (100 - x)%.

In this problem, he scored on the 20th percentile, that is, higher than 20% of the 50 students. Then:

0.2 x 50 = 10.

10 students scored lower than he did.

Help me out 3 i need some help :(
Alenkinab [10]

Answer:

The first one

Step-by-step explanation:

Since only the first session is $10, it wouldn't be 10x.

The second session is $5, and it will never be $10 again, so $5 sessions are unlimited which would be 5x.

So the answer is y = 10 + 5x

(sorry if i didnt explain well)

Vanessa throws a tennis ball in the air. the function h(t) = -16t2 + 45t + 7 represents the distance, in feet, that the ball is
antiseptic1488 [7]
Given that height, h(t) of a tennis ball is modeled by the equation h(t)=<span>-16t^2 + 45t + 7, the time taken for the ball to reach maximum height will found as follows:
at maximum height:
h'(t)=0
but from the equation:
h'(t)=-32t+45=0
solving for t we get
t=45/32
t=1.40625~1.4 seconds
Thus the time taken to reach maximum height is 1.4 seconds
