Delvig [45]3 years ago
8 0

Answer:

Step-by-step explanation:

AC = 50 cm

BC = 14 cm

Pythagorean theorem,

AB² + BC² = AC²

AB² + 14² = 50²

AB² + 196 = 2500

AB² =  2500 - 196

AB² = 2304

AB = √2304

AB = 48 cm

Sense there's only a y, you'd assume y is 1 or 1y.

you'd make the 1 a negative 1 to get rid of the subtraction sign.

you'd add together the 2 ys making it 2y. then add -1 + 3, which would be 2.

so, the answer would be 2y + 2.

number of interval that involve the mean for 95% confidence interval is calculated as

We know that when we measure the 99 percent confidence interval, 99 outof 100 confidence interval are required to provide the mean population.

similarly

Assuming we measure a confidence interval of 95 percent, then we  should expect 95 out of 100 confidence interval to provide the mean population therefore, answer is 95
