Grayson charges $35 per hour plus a $35 administration fee for tax preparation. Ian charges $45 per hour plus a $15 administrati
frosja888 [35]

Answer:

h less-than 2

Step-by-step explanation:

Let

h ---> the number of hours

y ---> the total charge in dollars

we know that

The linear equation is slope intercept form is equal to

y=mh+b

where

m is the slope or unit rate of the linear equation

b is the y-intercept or initial value of the linear equation

we have

<em>Grayson</em>

The slope is equal to m=\$35\ per\ hour

The y-intercept is b=\$35

so

The total charge is equal to

y=35h+35 ----> equation A

<em>Ian</em>

The slope is equal to m=\$45\ per\ hour

The y-intercept is b=\$15

so

The total charge is equal to

y=45h+15 ----> equation B

For what number of hours does Grayson charge more than Ian?

The inequality that represent this situation is

35h+35 > 45h+15

solve for x

Group terms

35-15 > 45h-35h

20 > 10h

Divide by 10 both sides

2 > h

Rewrite the expression

h< 2\ hours ----> h less than 2 hours

According to these measures, is it possible that the heaviest piece of fruit in the two samples was an orange? Explain why or wh
aleksley [76]

Answer:

Yes,

Step-by-step explanation:

The measures given which are median and interquartile range have no effect on what the maximum value of a certain distribution will be.

In essence, the information given about the samples of fruits and apples do not point to which fruit sample should possess the sample with maximum weight as the information only gives a general description of each distribution. This means that either samples of orange or apple could have the heaviest piece of fruit.

A bag contains 10 white, 12 blue, 13 red, 7 yellow, and 8 green wooded balls. A ball is selected from the bag and kept. You then
Juli2301 [7.4K]

Answer:

0.096

Step-by-step explanation:

The bag contains 10 white , 12 blue, 13 red , 7 yellow and 8 green balls.

All the events of drawing a ball will be independent

so selecting one ball white and one red will be

using the multiplication rule of probability we get

P= P(blue)* P(white) + P(white)*P(blue)

as its said to get one blue and one white but does not specify to get which ball at which place  

P= \frac{12}{50}*\frac{10}{50} + \frac{10}{50}*\frac{12}{50}

P= \frac{240}{2500} = 0.096
