Answer: 2p - 2q

Step-by-step explanation:

(3p-10q)-(p-8q) is simply an algebraic expression.

To solve it, you first open the brackets

i.e 3p - 10q - p + 8q (the minus sign between the brackets have multiplied the next minus sign, so it becomes plus sign)

Now, collect the like terms of i.e common terms

= 3p - 10q - p + 8q

= 3p - p - 10q + 8q

= 2p - 2q

Thus, the final expression is 2p - 2q since it cannot be further simplified.

Elena L [17]

The trinomial did she factor is $\rm x^2-4x-12$ .

Given

Leonora is factoring a trinomial.

The factors of the trinomial are shown on the model.

<h3>Quadratic equation</h3>

It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there.

Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.

Algebra tiles are tiles used to represent variables or numbers and are rectangular or square-shaped.

1 is labeled + x squared, this gives x².

And 6 are labeled negative. 3 tiles are in the Factor 2 spot:

1 is labeled x and 2 are labeled. 0 tiles are in the Product spot.

-6x + 2x -12

Therefore

The trinomial did she factor is;

$\rm x^2-4x-12$

Hence, The trinomial did she factor is $\rm x^2-4x-12$ .

More about the quadratic equation link is given below.

Legalize Marijuana, Part II. As discussed in Exercise 6.12, the 2010 General Social Survey reported a sample where about 48% of

kvv77 [185]

Answer:

Around 2397 Americans must be surveyed to get a margin of error of 2%.

Step-by-step explanation:

We are given the following in the question:

Proportion of US residents who thinks marijuana should be made legal = 48%

$\hat{p} = 0.48$

We have to construct a 95% confidence interval.

Margin of error = 2% = 0.02

Formula for margin of error =

$z_{stat}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$

$z_{critical}\text{ at}~\alpha_{0.05} = 1.96$

Putting values, we get,

$0.02 = 1.96\times \sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}\\\\0.02 = 1.96\times \sqrt{\dfrac{0.48(1-0.48)}{n}}\\\\\sqrt{n} = 1.96\times \dfrac{\sqrt{0.48(1-0.48)}}{0.02}\\\\\sqrt{n}=48.96\\n = 2397.0816\approx 2397$

Thus, around 2397 Americans must be surveyed to get a margin of error of 2%.
