Answer:

You have not added the options, therefore, I cannot provide an exact answer. However, I can help you with the concept.

In any fraction, the denominator cannot be equal to zero because this would make the fraction undefined.

Excluded values are the values that would make the denominator equal to zero.

We are given that the excluded values are 2 and 5, this means that the factors of the denominator are (x-2) and (x-5)

This means that the denominator is x² - 7x + 10

Pick the fraction which has this denominator.

Hope this helps :)

At a local restaurant, the amount of time that customers have to wait for their food is normally distributed with a mean of 18 m

anyanavicka [17]

Answer:

95% of the customers have to wait between 10 minutes and 26 minutes

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 18 minutes

Standard Deviation, σ = 4 minute

We are given that the distribution of amount of time is a bell shaped distribution that is a normal distribution.

Empirical Formula:

Almost all the data lies within three standard deviation from the mean for a normally distributed data.
About 68% of data lies within one standard deviation from the mean.
About 95% of data lies within two standard deviations of the mean.
About 99.7% of data lies within three standard deviation of the mean.

Now, we can write:

$10 = 18-2(4) = \mu - 2(\sigma)\\26 = 18+2(4) = \mu + 2(\sigma)$

Thus, by empirical formula, 95% of the data lies within two standard deviations of the mean.

Thus, 95% of the customers have to wait between 10 minutes and 26 minutes

ory has designed a special table with a circular cutout in the center to be filled with glass. The radius of the cutout is 7 inc

irakobra [83]

Based on the area of the tabletop with the inner circle, the area after the inner circle has been cut out is 12,309 inch².

<h3>How do we find the new area of the tabletop?</h3>

We are told that the area of the tabletop is 12,463 inch².

We then need to find the area of the circlular cutout as:

= π x radius x radius

= 3.14 x 7 x 7

= 154 inch²

The new area after the cutout is removed is therefore:

= Current area - area of circular cutout

= 12,463 - 154

= 12,309 inch ²

Rest of the question:

Area of table including the cutout is 12,463 square inches.

Samuel solved the equation h - 234 = 1,192 and found the solution to be h = 958. Is he correct? If not, why not?

prohojiy [21]

Answer:

Step-by-step explanation:

h -234 = 1,192

-234 is a negative and if you add a negative number with a positive you have subtract and the remaining is your answer.

1,192+234=1,426

1,426-234=1,192

h=1,426
