3(n+5) < 3/4(n)
The three is multiplied by n+5. Whenever you see "is equal to/greater/less than," that is where you put your =, >, or < signs. Your variable, "n" represents the number. So three-fourths of the number is the same as multiplying the number by three-fourths.
Answer:
So the answer for this case would be n=737 rounded up to the nearest integer
Step-by-step explanation:
We have the following info given:
the sample mean
the sample deviation
represent the sample size
The degrees of freedom are given by:
The margin of error is given by this formula:
(a)
And on this case we have that ME =0.25 and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(5)
The confidence level is 95% and the critical value for this case would be given by 
, replacing into formula (5) we got:
So the answer for this case would be n=737 rounded up to the nearest integer
Answer:
glookin for da points brotha
Step-by-step explanation:
The answer to 2 is <span>√30/5 or 1.09545
First, you multiply the numerator and denominator by </span>√5.
√6x<span>√5=√30
</span>√5x<span>√5=5 (when a square root of an expression is multiplied by itself, the result is that expression) Therefore, the answer is </span><span>√30/5 or 1.09545
</span>
