Andru [333]

Answer:

The unit rate is 1.25 seconds per jump.

Step-by-step explanation:

Given:

Will can jump rope at a rate of 8 jumps for every 10 seconds.

Now, to find the unit rate:

So, by dividing we get the unit rate.

At the rate of 8 jumps Will takes 10 seconds.

Thus, for the rate of 1 jump he will take = $10\div 8=1.25\ seconds.$

Therefore, the unit rate is 1.25 seconds per jump.

o-na [289]

Answer:

542

Step-by-step explanation:

We are required to find the sample size at 98% confidence interval in this question

E = 0.04

P* = 20% = 0.20

n = p* x (1-p)(Zα/2÷E)²

α = 1 - 0.98

= 0.02

To get Critical value

= 0.02/2 = 0.01

The critical value at 0.01 is 2.33

Inserting values into formula:

O.2 x 0.8(2.33/0.04)²

= 0.8 x 0.2 x 58.25²

= 542.89

The value of n must be an integer therefore the answer is 542.
