Answer 1

Answer:

Answer:

Option B. 6

Step-by-step explanation:

Jalen is buying a new car. His options are below:

Model : Compact, luxury, sport = 3 options

Transmission : automatic, manual = 2 options

Color : red, blue, black, yellow = 4 options

Jalen decides that he wants a yellow car.

Now he has total number of choices = 3 × 2 = 6 choices

Option B. 6 choices is the answer.

Answer 2

Answer: The total number of choices Jalen has is six

What is the mean of 72,73,86,59,75,58,50,55

Answers

MEAN

Mean is the average. To find the mean of a data set, you have to add all the numbers and divide the sum by the amount of numbers you added.

In this equation, you have 8 numbers. That means you will be dividing by 8.

The first thing you need to do is add all the numbers. Add:

$72+73+86+59+75+58+50+55 = \bf 528$

Now that you have added all the numbers and got the sum, divide by 8. Remember that you will be dividing by 8 since you added 8 numbers.

Divide:

$528 / 8 = \bf 66$

The mean is 66

If you have any questions, feel free to ask in the comments! :)

The answer is 66.

Step by step explanation:
First, add all of the numbers together.
Then, divide the sum of the numbers by the number of entries you see.

Since there’s 8 numbers, you divide it by 8.

Last graph (D)

Step-by-step explanation:

$f(x)=x(x-2)(x+4)$

Find the zeros:

$f(x)=0\iff x(x-2)(x+4)=0\iff x=0\ \vee\ x-2=0\ \vee\ x+4=0\n\n\boxed{x=0}\ \vee\ \boxed{x=-2}\ \vee\ \boxed{x=-4}$

A graph with that x-intercepts is the last graph.

The second and third graphs are graphs of the quadratic function.

We have the function third degree (graph A and D).

How do you solve 9(2x --8) =5x-7 ?

Answers

9(2x --8) =5x-7
step 1: simplify 18x - 72 = 5x - 7
23x = -79
step 2: solve it x = -3.43

First use distrib. property of mult.
9(2x-8) = 5x - 7 so
18x - 72 = 5x -7
18x-5x = -7+72
13x = 65
13/13x = 65/13
x = 5
Check Ans: 18*5 -72 = 5*5-7
18 = 18 √

Which values are in the solution set of the inequality -9/4x+12≥-8? Select all that apply. A. 6 B. 7 C. 8 D. 10 E. 11

Answers

Answer: A, B, C

Step-by-step explanation:

To solve for the inequality, we would solve it as if it had an equals sign.

$-(9)/(4) x+12\geq -8$ [subtract both sides by 12]

$-(9)/(4) x\geq -20$ [multiply both sides by -4/9, remember to flip inequality]

$x\leq (80)/(9)$

Now, we know that the solution is less than or equal to 80/9, which is approximately 8.89.

Looking at the answer choices, A, B and C are the answers since they are both less than 8.89.

Final answer:

The solution to the inequality is all x that are less than or equal to 8.89. Therefore, from the given options A. 6, B. 7, and C. 8 are in the solution set.

Explanation:

To find the values in the solution set of the inequality -9/4x+12≥-8, we need to isolate x by subtracting 12 from both sides of the inequality giving us -9/4x≥-20. Then, we can solve for x by dividing both sides of the inequality by -9/4, remembering to reverse the inequality symbol because we are dividing by a negative number. This gives us x≤(20)(-4/9), which simplifies to x≤80/9. Now, we can check which values from the options A, B, C, D, and E are less than or equal to 80/9.

A. 6: 6 is less than or equal to 80/9.
B. 7: 7 is less than or equal to 80/9.
C. 8: 8 is less than or equal to 80/9.
D. 10: 10 is not less than or equal to 80/9.
E. 11: 11 is not less than or equal to 80/9.

Therefore, the values in the solution set of the inequality are A, B, and C.
