K(x) = 5x-6
(k+k)(x) = k(x) + k(x) = 5x-6 +5x-6
just plug in x = 4,
(k+k)(4) = 5(4) -6 + 5(4) -6
thats your answer, the last option.
50/8
Simply divide 8 into 50. That is 6. Because 8 *6 = 48.
There would be a remainder of 2.
So 50/8 = 6 whole number 2/8.
So the answer = 6 whole number 2/8. As mixed fraction.
You can reduce the 2/8 to 1/4.
So 6 whole number 1/4 is also correct.
Answer:
The bill size can be considered usual.
Step-by-step explanation:
Mean (μ) = $108.43
Standard deviation (σ) = $36.98
Now, consider the distribution to be normal distribution :

Now, finding values of z-score from the table. We get,
P(Z > 1.75) = 0.9599
⇒ 95.99%
So, only 4.01 % of the people in the city wastes water.
Hence, the bill size can be considered usual.
