Answer:
The upper bound is 399.5
Step-by-step explanation:
Let's start by calculating the mean value of the distribution as the addition of all values given divided by 12:
Average = 289.75.
If the standard deviation is 56, then the upper bound in 95% the confidence interval for the mean price of the phones is going to be given by the mean value added to 56 times 1.96 (since 95% of the population is withing 1.96 times the standard deviation)
That is: 289.75 + 56 * 1.96 = 399.51
which rounded to one decimal place gives: 399.5

Answer:
Multiply each side by −5, add 25 to each side
Step-by-step explanation:
-1/5(x-25) = 7
Multiply each side by -5/1 to clear the fraction
-5/1* -1/5(x-25) = 7*-5/1
x-25 = -35
Then add 25 to each side
x-25+25 = -35+25
x = -10
Answer:
