We can actually deduce here that when sketching a parabola, use <u>FOIL</u> to make both sides even and avoid extra calculations.

<h3>What is FOIL in mathematics?</h3>

In mathematics, FOIL is actually known to be an acronym that stands for First, Outer, Inner and Last. It is used to multiply two binomials which are seen as numbers.

We can see that FOIL can be used to make the both sides of a parabola even and to avoid extra calculations.

Reptile [31]

Answer:

The histogram of the sample incomes will follow the normal curve.

Step-by-step explanation:

According to the Central Limit Theorem if we have an unknown population with mean <em>μ</em> and standard deviation <em>σ</em> and appropriately huge random samples (<em>n</em> > 30) are selected from the population with replacement, then the distribution of the sample mean will be approximately normally distributed.

In this case the researches wants to determine the monthly gross incomes of drivers for a ride sharing company.

He selects a sample of <em>n</em> = 200 drivers and ask them their monthly salary.

As the sample selected is quite large, i.e. <em>n</em> = 200 > 30, the central limit theorem can be applied to approximate the sampling distribution of sample mean by the Normal distribution.

Thus, the histogram of the sample incomes will follow the normal curve.

A quarterback throws an incomplete pass. The height of the football at time t is modeled by the equation h(t) = –16t2 + 40t + 7.
Nostrana [21]
Indicated here when h(t) = 0, we are to find for the time where the football has reached a certain height. 


Then, the values of t would be -0.2 and 2.7.

Since we are to look for the time, it is impossible for us to have an answer that has a negative value. So based from our answer, the solution that we will eliminate is the -0.2 one. Since its value is negative.

So, the correct value would be the 2.7 sec. one.
