IgorLugansk [536]

Answer:

9(4 +5)

Step-by-step explanation:

there is a common factor of 9 in both 36 and 45

9*4 = 36

9*5 = 45

by factoring 9 out of both 36 and 45, we get 9(4 + 5)

15 people received an email and sent it to 3 different friends each, who in turn each sent it to 2 new people. What percent of t

pashok25 [27]

The original 15 people are 10% of the total number of people who received the mail.

Step-by-step explanation:

Given,

Number of people who received mail = 15

Mail further sent to 3 more friends;

Number of people who received mail from 15 people = 15*3 = 45 people

Number of people who received mail from 45 people = 45*2 = 90 people

Total number of people = 15+45+90 = 150 people

Now,

Percent of original people = $\frac{Number\ of\ original\ people}{Total\ number\ of\ people}*100$

Percent of original people = $\frac{15}{150}*100=10\%$

The original 15 people are 10% of the total number of people who received the mail.

A production supervisor at a major chemical company wishes to determine whether a new catalyst, catalyst XA-100, increases the m

zheka24 [161]

Answer:

a. n= 47

b. n= 128

Step-by-step explanation:

Hello!

The objective of this experiment is to test if the new catalyst, XA-100, increases the mean hourly yield of a chemical process, that is known to be μ=750 (pounds per hour) with the current process.

You need to calculate the sample size to estimate the population with determined error margins.

To do so, since you have no population information, only that it is approximately normal distributed, you'll use the Student t statistic to get the sample size.

The formula of the margin of error (d) is:

d= $t_{n-1: 1-\alpha/2}$ * ( $\frac{S}{\sqrt{n} }$ )
