Translate the statements into a confidence interval for p. Approximate the level of confidence. In a survey of 8451 U.S. adults,

Sedaia [141]

Answer:

The confidence interval is $0.304 < p < 0.324$

Step-by-step explanation:

From the question we are told

The sample proportion $\r p = 0.314$

The margin of error is $E = 0.01$

The confidence interval for p is mathematically represented as

$\r p - E < p < \r p + E$

=> $0.314 - 0.01 < p < 0.314 + 0.01$

=> $0.304 < p < 0.324$

Jim has received scores of 72 72 and 77 77 on his first two 100 point tests. what score must he get on his third 100 point test

Alisiya [41]

77+72=149
149/2=74.5
through the process of elimination, I found that Jim needs to get an 88 or higher to receive an average of 79 or greater.

77+72+88=237
237/3=79

Which set of three numbers could represent the lengths of the sides of a right triangle?

Lubov Fominskaja [6]

Answer=5,12,13

Just plug all of these values into the pythagorean theorem. If they work, then they could represent a right triangle.

For example:
5²+12²=13²
25+144=169
169=169
