Mr. Bloss made 36 out of 48 free throws while practicing for basketball. What percent of his free throws did he make?

Answers

Answer:

75%

Step-by-step explanation:

We can see that our fraction is 75/100, which means that 36/48 as a percentage is 75%.

Answer:

75%

Step-by-step explanation:

To find the percentage of successes, simply divide the number of successes by the number of tries. Hence 36/48=.75. Then, multiply by 100% to get the percentage value --> .75x100%=75%

Answers

Can you show more information please?

Answer:

Using technology, the linear regression equation which models the data of the relationship between the number of customers served and tips received is :

y = 1.87x + 3.66

predicted amount of tip for 100 customers = $191

The predicted amount of tips received of 100 customers are served :

y = 1.87x + 3.66

x = 100 ; substitute x = 100 into the equation

y = 1.87(100) + 3.66

y = 187 + 3.66

y = 190.66

Hence, about $191 would be received on tips if 100 customers are recorded.

Using a regression calculator to make prediction from a data table :

Enter the x and y axis data into the appropriate column so that the calculator can display the actual data model. Hence, given a certain value of either variable, the predicted value of the required variable can be calculated from the model.

Jacob sells homemade skateboard decks for a profit of $27 per deck. He is considering switching to a new type of material that will increase his profit, as expressed by the function y = 32x, where x is the number sold and y is the amount of profit.

How many more dollars will Jacob earn on each skateboard deck if he switches to the new material? Explain how you found your answer. (5 points)

Answers

Answer: I think that it is 32

Step-by-step explanation: I think this because in your equation it says (y=32x) which 32 will mean how much he is charging for each skateboard, x will be how many he sells, and y would be how much he makes from selling them. So if he sold 2 skateboards you would do 32 x 2 which equals 64 soo that would be (64=32x2) so it is 32

Answer:

-1/2x-2

Step-by-step explanation:

Distribute the negative sign from the right side to make the equation positive

1/4x - 7 + (-1)(3/4x) + (-1)(-5)

(basically multiplying -1 to 3/4x and -5 to eliminate it)

1/4x - 7 + -3/4x+ 5

Make the equation similar

(1/4x + -3/4x) + (-7 + 5)

combine like terms

1/4x + -3/4x = -2/4x --> Simplifies to -1/2x

Do the other integers

-7 + 5 = -2

Put it together
