Answer:
I cant solve number 1 but I can for number 2
Calculate GCF for each
You can learn how to use the prime factorization method to do this
GCF(12, 18, 40, 45) = 1
So I dont get what the problem is because there are no numbers for #2. So either I dont understand the problem or it is a trick question whereas the answer is UNDEFINED/IMPOSSIBLE.
Answer:
Step-by-step explanation:
We define X the random variable that represent the heights of a population for ten year old children, and for this case we know the distribution for X is given by:
Where 
and 
We want to find this probability:
We can use the z score formula to solve this problem given by:
Using this formula we have:
And we can find this probability with this difference
We can use tables for the normal standard distribution, excel or a calculator and we got this
Amelia can make 9 bracelets in 25 mins
Step-by-step explanation:
45 - 20 = 25
The value of 0-((5)(-1)+(5)(-2)+(5)(-3)+(5)(-4)) is -40
<h3>What are integers?</h3>
An integer is a whole number (not a fractional number) that can be positive, negative, or zero.
Given:
0-((5)(-1)+(5)(-2)+(5)(-3)+(5)(-4))
= 0+5-10-15-20
=5-25-20
= -40
Hence, value of 0-((5)(-1)+(5)(-2)+(5)(-3)+(5)(-4)) is 40.
