Answers

Answer:

Two

Step-by-step explanation:

3,5 or 7 out of possible 12 spins

3 / 12  of the time she will win

$ 4 is   8 spins

8 spins * 3/12 = 2 wins

ANSWER
2 prizes

Step-by-step explanation:

$4 ÷ $0.5 = 8

Total points on spinner = (1,2,3,4,5,6,7,8,9,10,11,12)

Required for winning = (3, 5, 7)

5+7 = 12

3/12

P(win) = 3/12 simplified is  1/4

(1/4) × (8) = 2

Therefore, the answer is two prizes

Which figures demonstrate a single translation?

Select each correct answer.

Answers

Translation of a figure is the situation when a figure is moves from one place to another place. The size of the figure does not changes in translation. The figure does not rotate in the translation. As the option 3 (below the first option) and 4 demonstrate the single translation hence, option 3 and 4 is the correct option.

Given-

Given option shows the different translation and rotation of the original figure. It has to be known about the translation before checking the correct option.

What is translation?

Translation of a figure is the situation when a figure is moves from one place to another place. The size of the figure does not changes in translation. The figure does not rotate in the translation.

In option 1 the object flips to the opposite side of the figure figure. Thus the option 1 does not demonstrate the single translation.In option 2 (right to the first option) the figure flips to the opposite side of the original figure and then translate to other location. Thus the option 2 does not demonstrate the single translation.In option 3 (below the first option) the figure moves to southeast direction to its position. Thus the option 4 demonstrate the single translation. Therefore option 4 is the correct option.In option 4 the figure moves to right from its location. Thus the option 3 demonstrate the single translation. Therefore option 3 is the correct option.

As the option 3 (below the first option) and 4 demonstrate the single translation hence, option 3 and 4 is the correct option.

Veronica is running in a charity run. She raised d dollars for the charity
by asking people to sponsor her. On average, each person gave $28.
If Veronica had 12 people sponsor her, what was the total amount she
raised?

Answers

Answer:

$336

Step-by-step explanation:

On average each person gave $28 dollars, if 12 people sponsored her, what did she raise?

how to find this is very simple, she raised d =(total amount of money raised) in dollars, average means we assume that with any amount of people one person gave 28 dollars each.

Our problem would read out to be d(total amount she raised) is equal to $28 times x(amount of people who sponsored her) or d = 28 * x

If 12 people sponsored her

original equation:

d = 28 * x

equation with x known(12 people)

d = 28 * 12

to solve all we do is multiply 28 times the amount of people who sponsored her, in this case, its 12.

d = 336

we know that if 12 people sponsor her d, or the total amount she raised, is equal to $336

If 12 persons sponsored her and each gave her 28
You multiply 28x12 and you will get 336
So the amount she earned was $336

Graph the following pair of quadratic functions and describe any similarities/differences observed in the graphs.
f (x) = 2 x squared. G (x) = negative 2 x squared
a.

f opens downward; g opens upward; both pass through different y-intercepts
b.

both open downward; both pass through (0, 0)
c.

both open upward; both pass through different y-intercepts
d.

f opens upward; g opens downward; both pass through (0, 0)

Answers

The function f(x) opens upwards, while g(x) opens downwards, and both functions pass through (0, 0), so the correct option is d.

What are the similarities/differences observed?

Here we have the two functions:

[tex]f(x) = 2x^2[/tex]

[tex]g(x) = -2x^2[/tex]

Notice tat g(x) = -f(x), which means that g(x) is a reflection across the x-axis of f(x).

The graphs of these functions can be seen below, the one that opens upwards is f(x), the one that opens downwards is g(x).

Then we can conclude that the true statement is:

"f opens upward; g opens downward; both pass through (0, 0)"
