Unit price means the cost per unit.

I'll provide an example.

If 4 bars of soap cost $2.35, find the unit price. Round to the nearest cent if necessary.

Remember that the unit price is the cost per unit which in this case is the cost per bar of soap. Since $2.35 is the cost for 4 bars of soap, to find the cost per bar of soap, we divide 4 into $2.35.

When we do this, we get an answer of 0.587 which rounds up to 59 cents.

Therefore, the unit price for soap is 59 cents.

Suppose that the walking step lengths of adult males are normally distributed with a mean of 2.5 feet and a standard deviation o

Hitman42 [59]

Answer:

0.0668 = 6.68% probability that an individual man’s step length is less than 1.9 feet.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score 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 p-value, we get the probability that the value of the measure is greater than X.

Normally distributed with a mean of 2.5 feet and a standard deviation of 0.4 feet.

This means that $\mu = 2.5, \sigma = 0.4$

Find the probability that an individual man’s step length is less than 1.9 feet.

This is the p-value of Z when X = 1.9. So

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

$Z = \frac{1.9 - 2.5}{0.4}$

$Z = -1.5$

$Z = -1.5$ has a p-value of 0.0668

0.0668 = 6.68% probability that an individual man’s step length is less than 1.9 feet.

Tina's gross pay is $2680. How much of her gross pay will be deducted for FICA taxes?

Burka [1]

<span>2680 * 6.2% = $166
Make sure you add the amount that is supposed to be deducted when you attempt to solve your problems, I'm a visual learner and I usually find it best to write everything out to see where to go next. <3 do well my dear</span>

error analysis: a contractor purchases 7 dozen pairs of padded work gloves for $99.12. she incorrectly calculates the unit price

chubhunter [2.5K]

Answer:

Unit Price= $1.18

The error is that the contractor divided $99.12 by 7 and didn't multiply the 7 by the dozen (12) first, which lead to a mistake.

Step-by-step explanation:

To find the unit price:

1) multiply 7x12 = 84

to get the total amount of gloves

2) divide 99.12 by 84

to get the unit price

Find the slope between<br> the following points:<br> (1,12) and (-7,-10)

OLEGan [10]

Answer:

11/4

Step-by-step explanation:

To find the slope of a line given two points, we use the formula

m = (y2-y1)/(x2-x1)

= (-10-12)/(-7-1)

=-22/-8

=11/4
