Answer:

C) f(x) = 6.25x + 3

Step-by-step explanation:

In order to know which one of the functions could produce the results in the table we simply need to substitute the number of candy bars for x in the function and solve it to see if it provides the correct total weight shown in the table. If we do this with the functions provided we can see that the only one that provides accurate results would be

f(x) = 6.25x + 3

We can input the # of candies for x and see that it provides the exact results every time as seen in the table.

f(x) = 6.25(1) + 3 = 9.25

f(x) = 6.25(2) + 3 = 15.50

f(x) = 6.25(3) + 3 = 21.75

f(x) = 6.25(4) + 3 = 28

PLEASE HELPPPPP!!!! (answer in decimal)

Answer:

$\approx 0.482659$

Step-by-step explanation:

The experimental probability is the chance of an event happening based on data, or rather the experiment results, and not on a theoretical calculation. In essence, a theoretical calculation can be described by the following formula:

$\frac{desired}{total}$

However, the experimental probability can be described with the following formula:

$\frac{number\ of\ desired\ outcomes}{number\ of \ trials}$

The number of trials is the sum of the number of outcomes. In this case, the desired outcome is tails. Therefore, the experimental probability can be described using the following formula:

$\frac{tails}{total}$

One can also rewrite the formula as the following. This is because the total is the sum of the number of the two outcomes:

$\frac{tails}{heads+tails}$

Substitute,

$\frac{167}{167+179}$

Simplify,

$\frac{167}{346}$

Rewrite as a decimal:

$\approx 0.482659$
