In a sporting goods store, the ratio of footballs to soccer balls in stock is normally 8: 5. If there are 320 footballs in stock in the store, how many soccer balls are in the store?​

Answers

Answer 1

Answer:

200 soccer balls

Step-by-step explanation:

Proportion:

8/5 = 320/x

Cross Multiply:

320 x 5 = 1600

8 x X = 8x

Divide:

8x = 1600

x = 1600 / 8

x = 200

Alyssa performed an experiment to measure the acceleration of a falling ball. She ran the experiment many times. Her results were distributed normally, with a mean of 9.75 meters per second and a standard deviation of 0.08 meters per second. Alyssa can be 95% sure that her next measurement will fall between the values of and meters per second.​

Answers

Answer:

Alyssa can be 95% sure that her next measurement will fall between the values of  9.59  and  9.91  meters per second.

Step-by-step explanation:

I just took the test and got it right

The 95% measurement will fall between  9.59 m/s and 9.91 m/s

Given;

the mean of the normal distribution, m = 9.75 m/s

standard deviation from the mean, d = 0.08 m/s

To find:

the range of Alyssa's 95% data

let this range = X

The 95% of the data will fall within 2 standard deviation below and the above the mean.

2 standard deviation below the mean = m - 2d

2 standard deviations above the mean = m + 2d

From the given values,  m - 2d = 9.75 - 2(0.08) = 9.59 m/s

                                       m + 2d = 9.75 + 2(0.08) = 9.91 m/s

Thus, the range of the 95% data = 9.59 m/s < X < 9.91 m/s

Solve for e 0.75(8+e)=2-1.25e

Answers

0.75(8 + e) = 2 - 1.25e

0.75(8) = 6

6 + 0.75e = 2 - 1.25e

Add 1.25e on both sides

6 + 2e = 2

Subtract 6 on both sides

2e = -4

Divide the whole thing by 2

e = -2
0.75(8+e)=2-1.25e
0.75(8)+(0.75)(e)=2+-1.25e
6+0.75e=2+-1.25e
0.75e+6=-1.25e+2
0.75e+6+1.25=-1.25e+2+1.25e
2e+6=2
2e+6-6=2-6
2e=-4
2e/2=-4/2
e=-2

Dustin decides to try selling whole-wheat muffins and bagels at his farm stand. He has $60 to spend on ingredients and 8 hours to prepare the muffins and bagels that he will sell on opening day. One dozen muffins costs $10 and takes 1 hour to make, while one dozen bagels costs $15 and takes 3 hours to make. Graph all possible combinations of the food that meets his goal. Which combination of bagels and muffins would meet Dustin's goal?
A. 4 dozen bagels and 3 dozen muffins
B. 2 dozen bagels and 6 dozen muffins
C. 3 dozen bagels and 1 dozen muffins
D. 1 dozen bagels and 3 dozen muffins

Answers

Answer:

The correct answer is D.

Step-by-step explanation:

Option A establishes that 4 dozen bagels and 3 dozen muffins will be prepared, thus spending $ 30 and 3 hours on muffins and $ 60 and 12 hours on bagels. In total, $ 90 and 15 hours will be spent, so this option is not correct.

Option B establishes that 2 dozen bagels and 6 dozen muffins will be prepared, thus spending $ 60 and 6 hours on muffins and $ 30 and 6 hours on bagels. In total, $ 90 and 12 hours will be spent, so this option is not correct either.

Option C states that 3 dozen bagels and 1 dozen muffins will be prepared, which will spend $ 10 and 1 hour on muffins and $ 45 and 9 hours on bagels. In total, $ 55 and 10 hours will be spent, so this option is not correct.

Finally, option D establishes that 1 dozen bagels and 3 dozen muffins will be prepared, thus spending $ 30 and 3 hours on muffins and $ 15 and 3 hours on bagels. In total, $ 45 and 6 hours will be spent, with which this option is within the predetermined parameters, that is, the expense is less than $ 60 and the time is less than 8 hours.
