Answer: 6*Q= 6Q or 6*Q= y

Step-by-step explanation:

The product is the answer to a multiplication problem, therefore 6*Q will be the first part.

The second part will be the answer. Normally, this would be represented just by 6Q, but you can use another letter to represent it. We'll use y for an example.

6*Q= 6Q

or

6*Q= y

Answer:

You would expect for 35 people to have consumed alcoholic beverages.

Step-by-step explanation:

For each person, there are only two possible outcomes. Either they consumed alcoholic beverages, or they did not. The probability of a person having consumed alcoholic beverage is independent of any other person. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

Probability of exactly x successes on n repeated trials, with p probability.

The expected value of the binomial distribution is:

$E(X) = np$

We learned in Exercise 3.25 that about 70% of 18-20 year olds consumed alcoholic beverages in 2008.

This means that $p = 0.7$

We now consider a random sample of fifty 18-20 year olds.

This means that $n = 50$

How many people would you expect to have consumed alcoholic beverages

$E(X) = np = 50*0.7 = 35$

You would expect for 35 people to have consumed alcoholic beverages.

What I the slope of a line that is perpendicular to the line 2y-3x=8

Zolol [24]

<u>ANSWER</u>

$- \frac{2}{3}$

<u>EXPLANATION</u>

The given given equation is

$2y - 3x = 8$

We need to rewrite this equation in the slope-intercept form:

$y = mx + b$

We add 3x to both sides.

$2y - 3x + 3x=8 + 3x$

$\implies \: 2y = 3x + 8$

We divide through by 2 to get,

$y = \frac{3}{2}x + 4$

The slope of this line is

$m = \frac{3}{2}$

Let the slope of the line perpendicular to this line be 'n' .

Then the product of the slopes of two perpendicular lines is always negative 1.

$m \times n = - 1$

$\implies \: \frac{3}{2} n = - 1$

$\implies \: \frac{2}{3} \times \frac{3}{2}n = - 1 \times \frac{2}{3}$

$n = - \frac{2}{3}$

Therefore the slope of the new line is

$- \frac{2}{3}$

What are the coordinates of Point A after the

Flura [38]

Answer:

A' (-3,7)

B' (0,10)

C' (12,10)

D' (-2,-4)

Step-by-step explanation:

A' (-6+3 , 3+4) = (-3,7)

B' (-3+3 , 6+4) = (0,10)

C' (9+3 , 6+4) = (12,10)

D' (-5+3 , -8+4) = (-2,-4)
