The function f(h)=8.5h+320 models the amount of money Amy has in her savings after each hour of work.
Ksenya-84 [330]

Answer:

a) h: Number of hours

b) Slope of function

c) y-intercept

Step-by-step explanation:

We are given the following in the question:

f(h)=8.5h+320

The above function tells us about amount of money Amy has in her savings after each hour of work.

a) value of "h"

The above function tells us about the money saved by Amy after each hour of work.

Thus, h here stands foe the number of hours.

b)  meaning of the coefficient h

Comparing the given function to a linear function:

f(h) = mh + c

Thus, coefficient of h is the slope of the function and tells the change in amount of money saved by Amy per unit hour or it tells the change in amount of money when there is a unit increase in hour.

c) meaning of constant

The constant is the y-intercept and tells the amount of money saved by Amy after she have worked for zero hours.

Suppose 5 men and 7 women are on a crowded elevator. At the next floor, four people get off the elevator. Find the probability t
Svetach [21]

Answer:    \bold{\dfrac{1}{99}}

<u>Step-by-step explanation:</u>

There are 5 men and 7 women, which is a total of 12 people.  Finding the probability that none of the four people are women is the same as saying that all four people are men.

\dfrac{5\ men}{12\ total\ people}\ and\ \dfrac{4\ men\ remaining}{11\ people\ remaining}\ and\ \dfrac{3\ men}{10\ people}\ and\ \dfrac{2\ men}{9\ people}\\\\\\=\dfrac{5\times 4\times 3\times 2}{12\times 11\times 10\times 9}\\\\=\dfrac{(4\times 3)\times (2\times 5)}{12\times 11\times 10\times 9}\\\\=\dfrac{1}{11\times 9}\\\\=\dfrac{1}{99}

liq [111]

Answer:

Yes

Step-by-step explanation:

( {12.5)}^{2}  = 156.25...(1) \\ ( {7.5)}^{2}  + ( {10)}^{2}    \\ = 56.25 + 100  = 156.25...(2) \\ from \: equations \: (1) \: and \: (2) \\ ( {12.5)}^{2}  =( {7.5)}^{2}  + ( {10)}^{2}   \\  \therefore \: given \: side \: lengths \: form \: right \: \\triangle \\ (by \: converse \: of \: pythagorean \:  \\ theorem)
