<u>Answer:</u>

The correct answer option is 'Every tenth student in the main hallway between class.'

<u>Step-by-step explanation:</u>

Every tenth student in the main hallway between class would best represent the sample population since majority of the students transit this hallway unlike the rest of the options.

For instance, polling every tenth student in the library at lunch would result in the favor of views of students who frequently visit the library and polling every tenth student in the student section at the school football game would go in favor of those who prefer sports.

Solve 10 + 6(–9 – 4x) = 10(x – 12) + 8.
Luden [163]

Answer: x = 2

Step-by-step explanation:

<em>first, we remove the parentheses. </em>

10 - 54 - 24x = 10x - 120 + 8

<em>then, we just calculate that out.</em>

-44 - 24x = 10x - 112

<em>next, we move the terms.</em>

-24x - 10x = -112 + 44

<em>then, we collect the like terms and calculate it.</em>

-34x = -68

<em>finally, we divide both sides.</em>

x = 2

14. Two parallel lines l and m are intersected by a transversal t. If the interior angles on same side of transversal are (2x−8)
nlexa [21]

Answer:

70° and 110°

Step-by-step explanation:

It is given that, two parallel lines l and m are intersected by a transversal t.

The interior angles on same side of transversal are (2x−8)° and (3x−7)°.

We need to find the measure of these angles.

We know that, the sum of interior angles of the same side of the  transversal is equal to 180°. So,

(2x−8)° + (3x−7)° = 180°

⇒ 5x-15=180°

⇒5x=180°+15

⇒5x=195

⇒x=39

Put x = 39 in (2x−8)°,

(2x−8)° = (2(39)-8)°

=70°

Again put x = 39 in (3x−7)°,

(3x−7)° = (3(39)-7)°

=110°

So, the measure of these angles are 70° and 110°.

Which is the best estimate of the correlation coefficient for the scatter plot?
leva [86]

The best estimate for this correlation would be B) 0.9.

We can see that the number is constantly going up, which would throw out the D answer.

We can also see that for every time the x goes up 1, the y goes up a little less than one. We can see that in the ordered pairs that exist on the graph such as (3, 2), (8, 6) and (2.1, 1.9).

Since the y values are just lower than the x, the correlation would be just under one. Therefore, 0.9 is an accurate estimation.
