QveST [7]3 years ago

Answer:

If we used the quadratic formula to solve the equation we can say:

-b = -5

b² - 4ac = 13

2a = 2

Solving the first and last equations we get b = 5 and a = 1. Substituting these values into the second equation we get:

25 - 4c = 13

Solving this we get c = 3 so the answer is x² + 5x + 3.

finlep [7]

Answer:

The answer to your question is: # of times = 60.7

Step-by-step explanation:

data

7.4 billion people

each person occupied 13 inches

Earth circumference = 25000 miles

length of the lines = 13 in x 7.4 billion people

                               = 13 x 7 400 000 000

                              = 9.62 x 10 ¹⁰ in

Convert in to miles

                     1 mile  --------------- 63360 in

                     x mi     ---------------  9.62 x 10 ¹⁰  in

     x = 1518308.1 mi

Now divide, the line of people by the circumference

         # of times =  1518308.1 mi /  25000 mi = 60.7

The third choice - 65.3%.

He made 66 successful attempts out of 101 total free throws. To find the experimental probability, it will be 66 divided by 101.

66 successful / 101 total attempts = 0.6534

Rounded off to the nearest tenth of a percent - 65.3%
The experimental probability that you make a free throw is 65.3%.
