Answer 1

Answer:

For every 7 books Ethan read, Sadie read 3 books.

Step-by-step explanation:

For every 21 books Ethan read, Sadie read 9 books.

Unsimplified Ratio = 21:9

21 and 9 have a common factor of 3.

Because 21 and 9 share a common factor we can simplify the ratio

21 / 3 = 7

9 / 3 = 3

The new ratio is 7 to 3

So for every 7 books Ethan read, Sadie read 3 books.

Answer:

D. The company's chocolate bars weigh 3.2 ounces on average.

Step-by-step explanation:

The company took many large samples, and each time the mean weight of the sample was within the 95% confidence interval.

Definition of 95% confidence level: 95% confidence level means a range of values that you can be 95% certain contains the true mean of the population.

Thus by considering definition we can conclude that The company's chocolate bars weigh 3.2 ounces on average.

Thus Option D is correct.

the volume of a sphere is 4851 cubic cm find its diameter​

Answers

Answer:

The diameter is 21 cm

Step-by-step explanation:

The formula for the volume of a sphere is V = (4/3)πr³, or (in terms of the diameter)  V = (4/3)π(d/2)³.  This simplifies to

       4πd³          πd³

V = ----------- = -----------

        3·8               6

Now equate V = (πd³/6) to 4851 cm³.  We must first solve this for d³ and then take the cube root of the result:

πd³ = 4851(6) = 29106.

Dividing this result by π yields 9264.7,

and taking the cube root of this is 21.  The diameter is 21 cm
