14x+7
b
(-13n)-(17-5n)
-13n-17+5n
-8n-17

c
(4y-7)-(y-7)
4y-7-y+7
3y

d
(-w+0.4)-(-w-0.4)
-w+0.4+w+0.4

Answer:

Confidence interval is 0.7 ≤ p ≤ 0.8

The margin of error is 7.1 %

Step-by-step explanation:

We have to calculate a 98% confidence interval for the proportion.

The sample proportion is p=0.75.

The standard error of the proportion is:

Here we have, the proportion or point estimate given by

= 150/200 = 0.75

Sample size, n = 200

The formula for confidence interval, CI, given a proportion, is;

At 98% z = ±2.326348

Plugging in the values of, , z and n we get;

CI = 0.6787704 ≤ p ≤ 0.8212296

To one decimal place, we have

CI = 0.7 ≤ p ≤ 0.8

What is the ratio of the least common multiple of 180 and 594 to the greatest common factor of 180 and 594

kherson [118]

Answer:

Step-by-step explanation:

least common factor of 180 and 594 is 5940.

greatest common factor of 180 and 594 is 18.

so, the ratio of the least common factor to the greatest common factor will be;

ratio = $\frac{5940}{18}$

= 330
