Answer:

Hours inequality (solution set): 0 ≤ x ≤ 7

Cost inequality: $2 ≤ y ≤ $100

Step-by-step explanation:

The babysitter charges $14 dollars per hour + bus fare

Price per hour = $14

Bus fare = $2

Mr. Tyler wants to spend no more than $100

Subtract the bus fare from the total amount, as that will not contribute to the babysitter's hours

$100 - $2 = $98

Divide by $14 per hour

$98 ÷ $14 = 7 hours

The maximum amount of time that Mr. Tyler could hire the babysitter for is 7 hours

This means that the hours cannot be greater than 7. It is given that x cannot be less than 0, because the babysitter cannot work negative hours.

0 ≤ x ≤ 7

This inequality shows that the Mr. Tyler will not have the babysitter work for less than 0 hours, or more than 7 hours. He will have to pay $2 minimum, or $100 max. Below is the inequality to represent this:

(y represents amount Mr. Tyler will pay)

$2 ≤ y ≤ $100

Hope this helps :)

A company produces packets of soap powder labeled "Giant Size 32 Ounces." The actual weight of soap powder in such a box has a N
Stolb23 [73]

Answer:

0.0764

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

\mu = 33, \sigma = 0.7

What proportion of boxes is underweight (i.e., weigh less than 32 oz)?

This is the pvalue of Z when X = 32. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{32 - 33}{0.7}

Z = -1.43

Z = -1.43 has a pvalue of 0.0764, which is the correct answr
