Well, 340/8=42.5
So you're pumping 42.5 gallons per minute.
42.5×20=850
It pumps 850 gallons in 20 minutes.

Answer:
y = 3x-2
Step-by-step explanation:
We can find the slope using the equation for slope
m = (y2-y1)/(x2-x1)
= (13-4)/(5-2)
= 9/3
= 3
We know the slope and a point, so we can use point slope form to make an equation
y-y1 = m(x-x1)
y-4 = 3(x-2)
Distribute
y-4 = 3x-6
Add 4 to each side
y-4+4 = 3x-6+4
y = 3x-2
This is in slope intercept form (y= mx+b)
Answer:
For a bilateral test the p value would be:
Step-by-step explanation:
Information given
n=225 represent the sample selected
X=87 represent the households with incomes below the poverty level
estimated proportion of households with incomes below the poverty level
is the value that we want to test
z would represent the statistic
represent the p value
System of hypothesis
We want to check if the true proportion is equal to 0.32 or not.:
Null hypothesis:
Alternative hypothesis:
The statistic is given bY:
(1)
Replacing we got:
For a bilateral test the p value would be:
