An Ice Cream Machine Offers Three Flavors: Vanilla, Chocolate, And Strawberry. Each Flavor Can Be Served

Answers

Answer 1
Each section of the tree diagram (in this case the branches that say vanilla chocolate and strawberry) must add up to 1

so to answer you should do 0.45+0.35= 0.8
then 1-0.8 =0.2

so Z is 0.2
Answer 2

The value of z = 0.2

What is probability?

"Probability is a branch of mathematics which deals with finding out the likelihood of the occurrence of an event."

Sum of probabilities:

"The sum of the probabilities of all outcomes must equal 1."

For given situation,

An ice cream machine offers three flavors: vanilla, chocolate, and strawberry. Each flavor can be served as a milkshake, in a cone, or in a cup.

The probability of customers choosing Vanilla flavor = 0.45

The probability of customers choosing Chocolate flavor = 0.35

We need to find the probability of customers choosing Strawberry flavor i.e., to find the value of z.

The sum of the probabilities of all outcomes must equal 1.

From given tree diagram,

⇒ 0.45 + 0.35 + z = 1

⇒ 0.8 + z = 1

⇒ z = 1 - 0.8

z = 0.2

Therefore, the correct answer is option (A)

Debbie's town voted on a new speed limit. Out of 17 votes, 17 were in favor of the new speed limit. What percentage of the votes were in favor of the new speed limit?

Answers

Answer: The percentage of the votes were in favor of the new speed limit = 100%

Step-by-step explanation:

Given:  Total votes = 17

Total votes favored the new speed limit = 17

The percentage of the votes were in favor of the new speed limit [tex]=\dfrac{\text{Number of votes in favor}}{\text{Total votes}}\times100\\\\=\dfrac{17}{17}\times100\%=100\%[/tex]

Hence, the percentage of the votes were in favor of the new speed limit = 100%

Explanation
To solve the equation, you would substitute x and y for 5 and 8.
-Ex: 5(4)+8(2)=36
The numbers in the parentheses get multiplied by the numbers on the outside. Making ‘5(4)’=20 and ‘8(2)’=16
So 5(4)+8(2)=36

They are not traveling at the same speed (Graph attached)

Step-by-step explanation:

(Assuming that the graph and table are the two different cars)

If you look at the graph and the table, you can already see that the value for 8 in the graph is 2, when the value for 8 in the table is 1, meaning that they are not at the same speed.

To graph the table, you need to find the equation first, which is y = 8x because the corresponding value for 1 in the table is 8 and the slope (or the value next to x) is equal to the unit rate, or the value corresponding to 1. Next, you can graph it by finding two points, (0,0) and (1,8), and putting a straight line through them (or use an online graphing calculator).

The slope of line formed by given two points is undefined as the denominator becomes zero.

Step-by-step explanation:

Given points are:

(2,4) and (2,-2)

Here

[tex]x_1 = 2\\y_1 = 4\\x_2 = 2\\y_2= -2[/tex]

Slope is defined as the steepness of a line in the plane.

It is denoted by m and is given by the formula:

[tex]m = \frac{y_2-y_1}{x_2-x_1}\\[/tex]

Putting the values we get

[tex]m = \frac{-2-4}{2-2}\\m = \frac{-6}{0}\\m = \infty[/tex]

The slope of line formed by given two points is undefined as the denominator becomes zero.

Answers

Answer: You are correct, the solution is:

-2 + (-4) + 2 = -4

Step-by-step explanation:

We start at position -2, then we get 4 in the first dice, the first dice tell us how many units we move to the left, and at the left we have the negative side of the numberline then we need to subtract 4 to the starting position. This is:

-2 - 4

Or we can rewrite this as:

-2 + (-4)

Now we got a 2 in the second dice, this dice tell us how many units we move to the right, and we know that the right is the positive side of the numberline, then we need to add 2.

The equation becomes:

-2 + (-4) + 2 = -4

So you are correct.
