First distribute
a(b+c)=ab+ac
y(x+z)=yx+yz
3z(x+y)=3zx+3zy
so now we have
yx+yz=3zx+3zy
make all x's on one side
subtract 3zy frm btohs ides
yx-3zx+yz=3zy
subtract yz frmo both sides
yx-3zx=3zy-yz
undistribute the x on the left side
x(y-3z)=2zy
divide both sides by (y-3z)
x=
Answer:
Step-by-step explanation:
a. Given p=0.15.
-The mean of a sampling proportion of n=5000 is calculated as:
-The standard deviation is calculated using the formula:
Hence, the sample mean is μ=750 and standard deviation is σ=0.0050
b. Given that p=0.15 and n=1000
#The mean of a sampling proportion of n=1000 is calculated as:
#-The standard deviation is calculated as follows:
Hence, the sample mean is μ=150 and standard deviation is σ=0.0113
c. For p=0.15 and n=500
#The mean is calculated as follows:
#The standard deviation of the sample proportion is calculated as:
Hence, the sample mean is μ=75 and standard deviation is σ=0.0160

answer is 100 pages per hour
Answer:
Yes
Step-by-step explanation:
There is a proportional relationship between x and y it's 5.
Think about it when x is 1 y is 5
When x is 2 y is 10
When x is 5 y is 25
When x is 7 y is 35
To get this for this question all you have to do is multiply x by 5 to get y.
That's how you know it's proportional.
Hope this helps!!!
Y-intercept is (0,-7) x-intercept is (14,0)
