If you want an equation to be zero at two specific numbers p and q, you can write it as . In this case, your numbers will be
Note that a percentile tells us how many percents of numbers that are above the number at the percentile. So the 70th percentile tells us that 70% of the students are taller than Jake. That means 30% of the students are either at the same height or shorter than Jake.
30% of 1100 would be 0.3*1100 = 330.
So there are 330 students that are either at the same height or shorter than Jake.

ANSWER
EXPLANATION
We want to find the value of a for which the binomial, 2a-1 is smaller than the value of the binomial 7-1.2a by 7.
This means that, when we subtract 2a-1 from 7-1.2a, we should get 7.

Divide both sides by -3.2,
Answer:
The length of the focal width of the parabola is 1.
Step-by-step explanation:
Suppose we have a parabola with the following equation:
The centre is at point .
The length of the focal width is of |4p|.
In this question:
We want to place in the general format. So
Comparing, we have that 4p = 1. So the length of the focal width of the parabola is 1.
