A candidate for mayor wants to know how strong her support is among voters, so she posts an online survey on her campaign websit

maks197457 [2]

1) A. Biased because the population could be uneven. Too many of one ethnicity, too many of one gender, etc.

2) I believe this one is C. because there are not enough people. You need to survey the majority of parents instead of a selected few.

3) There are 80 green marbles per 500, therefore calculate the percentage. $\frac{80}{500}=0.16$ or $16$ percent. Multiply $16$ percent or $0.16$ times 25. It gives you $4$ .

4) This one is a probability thing too. For every 500 batteries, there are 3 that are defective, therefore, $\frac{3}{500}= 0.006$ .

$0.006*12000 = 72$

5) Yet another one. Add up all the nuts and you get $48$ . The chance of getting a cashew from these $48$ is: $\frac{9}{48}=0.1875$ .

Therefore: $0.1875*32=6$

2x+3=-7 What is the answer?

Mashcka [7]

Hi there! With equations like this we want to get our variable on one side and and our constant on the other.

So with 2x + 3 = -7 you'd subtract the constant 3 from both sides of the equal sign to get 2x = -10, then you'd divide both sides by 2 to get x = -5. If you double check your work by replacing x in the original equation with our answer we'd find that 2(-5) + 3 = -7 is correct.

Hope you find this helpful :)

Que How does your tessellation with triangles relate to hexagons and tessellating the plane? Type your response in the space bel

madreJ [45]

For a regular tessellation, the shapes can be duplicated infinitely to fill a plane such that there is no gap. The only shapes that can form regular tessellations are equilateral traingle(all sides are equal. This means that it can be turned to any side and it would remain the same), square and regular hexagon. Looking at the given options, we have

Shape Tessellate?

Octagon No

Hexagon Yes

Pentagon No

Square Yes

Triangle No(unless it is specified that it is an equilateral triangle)

Pls help me help me help me

Ganezh [65]

Answer:

C. -3/2

Step-by-step explanation:

Perpendicular lines have negative reciprocal slopes.

We know that line m is perpendicular to line l.

Line l has a slope of 2/3. To find the slope of line m, find the negative reciprocal of 2/3.

Negative: switch the sign

2/3 --> -2/3

Reciprocal: switch the numerator (top number) and denominator (bottom number)

-2/3 --> -3/2

Line m has a slope of -3/2 and C is correct.
