<u>Answer:</u>
<u>Step-by-step explanation:</u>
- -3(-3x - 7) = 48
- => 9x + 21 = 48
- => 9x = 48 - 21
- => 9x = 27
- => x = 3
<u>Conclusion: </u>
Therefore, the answer is 'x = 3'.

Answer:
y=26, x=-3
Step-by-step explanation:
3x+y=17
3x+y-y=17-y
3x=17-y
Divide both sides by 3
Simplify
\frac{17-y}{3}+2y=49
\frac{17-y}{3}\cdot \:3+2y\cdot \:3=49\cdot \:3
17-y+6y=147
17+5y=147
17+5y-17=147-17
5y=130
\frac{5y}{5}=\frac{130}{5}
y=26
x=\frac{17-26}{3}
x=-3

Answer: 0.9996
Step-by-step explanation:
Given : The monthly electrical utility bills of all customers for the Far East Power and Light Company are known to be normally distributed with a mean 
Standard deviation : 
Sample size : n=100
Let X be the random variable that represents the electricity utility bill for a randomly selected month .
z-score : 
For X = $75.00

Now, the probability that the average bill for those sampled will exceed $75.00 will be :-

Hence, the probability that the average bill for those sampled will exceed $75.00 =0.9996
