1. 22 students is 40% of 55

2. 24 red marbles is 40% of  60 marbles

3. 15% of $9 is $1.35

4. 12 is 6% of 200

5. Bethany sent 9 text messages to her friend yesterday.

6. There where 17.01 people in the survey.

7. The sales tax rate is 6.5%.

8. There were 10(0.1) from 18-29 that voted in the election.

9. There were 35(0.35) from 50-64 that voted in the election.

10. There were 25(0.25) of over 64 year old's that voted in the election.

11. Sahli  is incorrect because there is 30 people within ages 30-49. I think he came up with that answer so quickly because 30 + 49 = 1470 and divided by 14 = 105 with this you add 30 and get 135.

Monthly water bills for a city have a mean of $108.43 and a standard deviation of $36.98. Find the probability that a randomly s
GaryK [48]

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 :

P(Z=\frac{X-\mu}{\sigma}>\frac{a-\mu}{\sigma})=P(Z>\frac{173-108.43}{36.98})\\\\\implies P(Z>1.75)

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.
