Answer:
we say the number of samples is 4
Step-by-step explanation:
Given data
sample = 100
total sample conduct = 4 time
to find out
What is the number of samples
solution
we know that sample size for each month is 100
4 time sample taken January, march, June and September.
so that no of people sample is = 4 × 100 = 400
so that for number is sample is 400 /100
so we say the number of samples is 4
This looks like: 
To solve this problem, you'll want to use the AC method to factor x^2+7x-30.
After factoring your expression will look like this:

Cancel out the x+10 because they are common factors, so you are just left with the simple x-3.
Answer is:
x - 3
That's written as 5.6 x 10⁻¹⁷ .
(To change 5.6 into the original number, you'd need to
move the decimal point 17 places backwards.)
Answer:

Step-by-step explanation:
we are given
y varies directly as x
so, we can write equation as

where
k is constant of proportionality
We have
at x=-1 , y=6
so, we can use it to find k

so, we get

now, we can plug it back

now, we can plug x=5
and we get
