The answer is 21 because I added 8 + 10+3=and I got 21
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
The inequality that represents this phrase is n+6 > 31.
Answer:
x = -12/14 is the required solution for the given expression.
Step-by-step explanation:
Here, the given expression is:
5 – 6 x = 8 x + 17
Now, here solving the expression for the value of x, we get:
5 – 6 x = 8 x + 17
⇒ 5 - 17 = 8 x + 6 x
⇒- 12 = 14 x
or, x = -12 / 14
Hence, x = -12/14 is the required solution for the given expression.
