Answer:

B=5,0.

Step-by-step explanation:

It's not that hard. It's just that it might throw you off a bit with the R and the other things. Functions if you don't remember are where the coordinates don't have the same x and y. So since the y1 and y2 are different then to make it not a function, you have to make x1 and x2. To make it that b would have to be = to 5 and 0.

Answer:

A. p(hat) = .139

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

B. 1.62 million

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

C. No

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.

Find the missing value.-7/13 = m/104

exis [7]

$answer = - 56 \\ solution \\ \frac{ - 7}{13} = \frac{m}{104} \\ or \: 13 \times m = 104 \times ( - 7) \\ or \: 13 \: m = - 728 \\ or \: m = \frac{ - 728}{13} \\ m = - 56 \\ hope \: it \: helps \\ good \: luck \: on \: your \: assignment$
