A store sells 4 types of chocolate bars and surveyed 50 customers at random

Zanzabum

Hi there! The answer is D. 8%

To find the percentage of the customers who preferred the hazelnut bar we need to know two things:

First we need to know the total amount of customers, which is 50.
Second we need to know how many of these customers preferred the hazelnut bar. This bar is preferred by 4 people.

Now we can fill in the following formula, in order to find our percentage:
$\% = \frac{part}{total} \times 100 \% = \frac{4}{50} \times 100 \% = 0.08 \times 100 \% = 8 \%$

Hence, the answer is D. 8%

WHATS THE SLOPE <br> FAST CORRECT ANSWER = Thanks + Brainliest + 5 stars + 8 points

umka2103 [35]

Answer:

The slope of g(x) is: $m=0$

The slope of f(x) is: $m-1$

Step-by-step explanation:

For this exercise you need to know that:

1. By definition the slope of any horizontal line is zero ( $m=0$ )

2. The slope of a line can be calculated using the following formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

In this case, you can observe in the graph of the function g(x) given in the exercise that it is an horizontal line. Then, based on the explanation given before, you can conclude that its slope is:

$m=0$

To find the slope of the function f(x) shown in the table attached, you need to follow these steps:

- Choose two points from the table:

$(0,3)$ and $(4,-1)$

- You can say that:

$y_2=-1\\y_1=3\\\\x_2=4\\x_1=0$

- Substitute values into the formula $m=\frac{y_2-y_1}{x_2-x_1}$ :

$m=\frac{-1-3}{4-0}$

- Finally, evaluating, you get:

$m=\frac{-4}{4}\\\\m=-1$

Peggy practices her gymnastics routine for a total of 21 hours. Each practice session is 1 3/4 hours. How many practice sessions

Phoenix [80]

12 sessions.
EXPLANATION:
each session is 1 3/4 hours.
We need enough sessions for 21 hours.

the equation is 1 3/4 x f = 21

using the multiplication property of equality, we can do 21 divided by 1 3/4

The answer is 12 sessions.

Hope it helps!
