5 0

Answer:

233.75

Step-by-step explanation:

if 220 is 100% of the number we need to know how much 6.25% is so we would multiply 220 and 6.25 together then divide by 100 and we would get 13.75, so 13.75 id 6.25% of 220. We would then add 220 and 13.75 together and get 233.75

WILL AWARD BRAINLIEST!!!
Anna007 [38]

Answer:

<u>A. p(hat) = .139</u>

We divide our sample population by the amount who tested positive. 14851/107109 = .139.

<u>B. 1.62 million</u>

We just multiply the p times the population. 11.69 M * .139 = 1.62 M

<u>C. No</u>

It depends upon the sample method. From what I can tell, I assume all conditions are met and it was not biased.

If it wasn't random, that is a problem, but we aren't given this information.

We can test if it's small enough. It can't be larger than 10% of the population. 107109 * 10 < 11.69 million, so it's small enough.

We can also test if it's large enough. np and nq must be greater than 10. 107100 * .139 > 10, 107100 * .861 > 10.

1. Three apples, a, and two peaches, p, sell for $1.25.
Simora [160]

Answer:

$0.25

Step-by-step explanation:

You can use systems of equations to solve this.

3a+2p = 1.25

5a+p = 1.5

Multiply the second equation by 2.

3a+2p = 1.25

10a+2p = 3

Subtract the bottom from the top

-7a= -1.75

Divide by -7

a= 0.25

Each apple is $0.25 (in this case, the peach also costs $0.25)
