Answer:

340

Step-by-step explanation:

We can see in the sample that 18/50 people bring lunches to school. If we divide 18 by 50 we get 0.36 now we know that 36% of people bring their lunches in the sample. Now we take that number and multiply it by 942.

0.36*942= 339.12 which we can round to 340

18. what is the midpoint of PQ P(-2, 2.5), Q(1.4, 4)​
scoray [572]

Mid point of the points PQ is (₋0.3 , 3.25)

Given points are:

P(₋2 , 2.5)

Q(1.4 , 4)

midpoint of PQ = ?

A location in the middle of a line connecting two points is referred to as the midpoint. The midpoint of a line is located between the two reference points, which are its endpoints. The line that connects these two places is split in half equally at the halfway.

The midpoint calculation is the same as averaging two numbers. As a result, by adding any two integers together and dividing by two, you may find the midpoint between them.

Midpoint formula (x,y) = (x₁ ₊ x₂/2 , y₁ ₊ y₂/2)

we have two points:

P(₋2,2.5) = (x₁,y₁)

Q(1.4,4) = (x₂,y₂)

Midpoint = (₋2 ₊ 1.4/2 , 2.5₊4/2)

= (₋0.6/2 , 6.5/2)

= (₋0.3 , 3.25)

Hence we determined the midpoint of PQ as (₋0.3 , 3.25)

Using division, what is the quotient (2x3 − 2x − 12) ÷ (x − 2)?
topjm [15]

Answer:

2x^2 + 4x + 6

Step-by-step explanation:

First, we need to write the polynomial in descending order, since we have a missing term (x^2) we need to fill with zero:

2X^3+0x^2-2x-12

Then, grab the term with the highest  power from the polynomial and divide it by the term with highest power from the polynomial located at the other side of the division symbol (this polynomial would be x-2)

The result (2x^3 / x) = 2x^2

This term will be part of the solution, and will be use to start the process of division.

This process start with the previous obtained term (2x^2), which will be multiplied by the polynomial from the other side of the division symbol (x-2).

The result another is another polynomial

This new polynomial will be multiply by negative 1

The new polynomial is then added to the poly (2X^3+0x^2-2x-12)

The result will constitute a new poly, that will be use as the remaining of the division.

Since, our remaining differs from zero, and we still have member to simplify, we repeat the step 1 using the remaining as the new poly that needs to be divided by (x-2).

The attached picture explains the whole procedure.
