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: The answer is 5 but all of them are five but on the number line it’s going to the right with no fill in, it’s just a circle going to the right. Also it gives you a clue it says more than meaning greater than so it’s going this way > but the line is going this way 0———————-> on the number line with no black fill in.
Step-by-step explanation:
Answer: -2,000,000
Step-by-step explanation:
Think of it as -3,000,000 + 1,000,000
100-45+22= 77
you will have 77 percent of battery on your phone
Given:
Principal = <span>£100
Interest rate = 6%
Interest = </span><span>£12
Simple Interest is computed by multiplying the principal by its interest rate and term
Interest = Principal * rate * term
12 = 100 * 0.06 * term
12 = 6 * term
12/6 = term
2 = term
It will take 2 years for </span>£100 to earn <span>£12 at 6%</span>
