Answer:
The population mean is 5 volts
Step-by-step explanation:
Output voltage is assumed to be normally distributed, with standard deviation 0.25 Volts
s=0.25
n = 8
Sample mean = 
Since n < 30 and population standard deviation is unknown
So, we will use t test
Formula : 
t=-1.69
Refer the t table for p value
Degree of freedom = n-1 = 8-1 = 7
So,
P value >α
So, We are failed to reject null hypothesis
Hence The population mean is 5 volts
Answer: x= 8\sqrt{3} over 3, x= 8 \sqrt{3} over 3
Step-by-step explanation:
Answer:
2 1/4 gallons or 2.25 gallons
Step-by-step explanation:
3/4 is 1/3 of the wall
then 9/4 is all of the wall
so 9/4 simplified is
2 and 1/4 gallons
Answer:
5
Step-by-step explanation:
10 = 2 * 5
125 = 5 * 5 * 5
Taking out the duplicates from the 2 lists :- GCF = 5
Answer:
y = 5x
Step-by-step explanation:
since y varies directly as x then the equation connecting them is
y = kx ← k is the constant of variation
to find k use the condition y = 60 when x = 12, then
k = 
= 
= 5
y = 5x ← is the equation of variation
