Answer: $8.75 for 250 vitamins.

Step-by-step explanation:

To find how much each vitamin costs we can divide $5.25 by 150.

5.25/150 = 0.035. So each vitamin is equal to $0.035.

We can then multiply the cost of 1 vitamin by 250.

0.035 x 250 = 8.75 or $8.75.

We can also make an equation for this problem. Let the total cost be equal to y and each vitamin equal to x.

y = 0.035x

So the equation above states that the total cost, y, is the amount of vitamins that are bought.

The letters of the word S U M M E R were placed in a bag. What is the probability of choosing an R?
lawyer [7]

There is only one R in the bag

So the probability would be 1/6

1/6 as a decimal is 0.16

Thus, your answer would be option D

A) The pointer lands on an even number more often than expected
fgiga [73]

Answer:

The correct answers are A, D, and E.

Step-by-step explanation:

The expected probability of the spinner landing on an even number is 50%, or 125 times. However, it lands on an even number 135 times, which is equal to 54%. This is more than expected. The actual probability is the probability after an experiment has been conducted, therefore the actual probability of landing on an odd number is 46%. The expected probability is the probability before an experiment is conducted, so it is 50%. It is equally likely for the spinner to land on an even or odd number, because each spin is an independent event.

I hope this helps!

A polynomial function can be written as (x + 2)(x + 3)(x − 5). What are the x-intercepts of the graph of this function? (1 point
Marizza181 [45]

Answer:

(-2, 0), (-3, 0), and (5, 0)

Step-by-step explanation:

The x-intercept is found when <em>y = 0</em>.

So, we have to find x when <em>(x + 2)(x + 3)(x - 5) = 0</em>

We can do that by pulling apart all parts, because if one part = 0, the whole thing will have to be too (multiplication property of identity).

1. When x + 2 = 0, x = -2

2. When x + 3 = 0, x = -3

3. When x - 5 = 0, x = 5

That gives us (-2, 0), (-3, 0), and (5, 0)
