Hey!
I assume you're talking about percentage. What was the percentage increase from 86 books to 150.
Using the formula to find percentage increase, we will solve this:
{(86 - 150) / 86} × 100 = 74.42
So, the percent increase from 86 books to 150 is 74.42%
Answer:
a) 62%
b) 44%
Step-by-step explanation:
Beforehand we have the information that the amount of shoppers, let`s call it n= 150.
To answer the first question, we need to know the amount of shoppers that do not possess an email account: this is the sum= 18`+75 (both the shoppers without and with access to a computer at home buth without an email). Lets call it a.
The percentage is defined by:
%of shoppers that dont have and email account= a/n*100= (18+75)*100/150= 62%
The next question is the percentage of shoppers with computer access at home, thus the sum of 48+18, both who have and dont have an email account but the have computer access at home. Lets call it b.
So
%of shoppers that have computer access at home = b/n*100= (48+18)*100/150= 44%
Answer:
Part a
The regression equation is, 
Part b
The number of crimes for a city at 20 police officers was appointed is approximately 10.
Step-by-step explanation:
<u>x y xy x² y²</u>
15 17 255 225 289
17 7 119 289 49
17 13 221 289 169
12 21 252 144 441
25 5 125 625 25
11 19 209 121 361
27 7 189 729 49
22 6 132 484 36
146 95 502 2906 1419
Therefore,


The calculation of the intercept coefficient is as follows:


The regression equation is, 
b)
The calculation is as follows:

≅ 10
The number of crimes for a city at 20 police officers was appointed is approximately 10.
The number of crimes for a city at 20 police officers was appointed is approximately 10.
That is, the number of polices increases then the number of crimes will be decreases.
So i think what you do is if you make a number line like this:
1...2...3...4...5...6...7...8
you have to find out how many numbers are in between 4 and 7, so I would be 3 because there are 3 numbers I between 4-7.
so
a) 3
b) 6
c) 14
d) 8
2752 is this because this is hard ending as
