Answer:

They are dependent

Step-by-step explanation:

A dependent event is one in which its chances of happenning greatly relies on another event. An independent event which is the opposite is one in which its chances of happening is unaffected by another event. In the event described in the question above returning the rented movie after the due date would result in receiving a late fee.

One of the events- receiving a late fee, depends on when the rented movie is returned. This means that the events are dependent.

Answer:

190

Step-by-step explanation:

19 × 10 =190

if you multiply it it will be ten times larger

Answer:

190

Step-by-step explanation:

Answer:

$120

Step-by-step explanation:

$120-75% is $30. 1/4 of $120 is $30, so 3/4 is $90. $120-$90 is $30. To find the answer to future equations like this, just multiply the sales price by 4 if the percentage is 75.

It is not $52.50, because 75% of that is $39.375, making that one's sales price 13.125.

Answer:

$52.50 is the original price

Step-by-step explanation:

In order to find the answer, multiply $30 * 0.75 which equals $22.50 and add $30 + $22.50 which would equal $52.50

Answer:

1.5 hours

Step-by-step explanation:

Number of miles = 25 miles

Average speed = 7.4 miles per hour

Break after 13.9 miles

How many more hours does he run

Speed = distance / time

Total time for 25 miles :

Time = distance / speed

Time = 25 / 7.4

Time = 3.378 hours

Total time to cover 13.9 miles :

Time = 13.9 / 7.4

Time = 3.378 hours

Time = 1.878 hours

Difference = (3.378 - 1.878) hours = 1.5 hours

Hence, he to ran for 1.5 hours after taking a break

The total time required for the 25 miles run is 3.378 hours and he will run for 1.5 hours after the break.

Given information:

Roberto runs 25 miles.

The average speed is 7.4 miles per hour.

He takes a break after 13.9 miles.

Now, speed is defined as the ratio of distance and time.

So, the time taken by him to run first 13.9 miles will be,

[tex]s=\dfrac{d}{t}\\7.4=\dfrac{13.9}{t_1}\\t_1=1.878[/tex]

So, he ran for 1.878 hours to cover 13.9 miles.

Now, the total time of the 25 miles run will be,

[tex]T=\dfrac{25}{7.4}\\T=3.378[/tex]

So, the total time of the run is 3.378 hours.

After the break, he will run for 3.378-1.878 hours = 1.5 hours.

Therefore, the total time required for the 25 miles run is 3.378 hours and he will run for 1.5 hours after the break.

Step-by-step explanation:

Given

Represent acceptable with A and defective with D

[tex]A = 70\%[/tex]

[tex]B = 30\%[/tex]

Required

Determine the probability that three selected are acceptable

This can be represented as:

[tex]Probability = AAA[/tex]

Substitute values for A

[tex]Probability = 70\% * 70\% * 70\%[/tex]

[tex]Probability = 34.3\%[/tex]

Answer:

Step-by-step explanation:

Distance = speed * time

For Ben:

speed = 3mi/hr

Time = (x+1.5)hr

Distance = 3 * (x+1.5)

Distance = 3(x+1.5)

For Amanda:

Speed = 7mi/hr

time = 1x

Distance = 7x

Since they cover the same distance then:

3(x+1.5) = 7x

3x + 4.5= 7x

3x-7x = -4.5

-4x =-4.5

x = 4.5/4

x =  1.125 hr

The time taken  by Amanda is 1.125 hr

Answer:

80 milligrams

Step-by-step explanation:

The volume of bottle is 16-ounce, and the amount of vitamin C in the bottle is 200 mg.

Since the 16-ounce bottle of orange juice says it contains 200 milligrams of vitamin C, which is 250% of the daily recommended allowance of vitamin C for adults. Then for 100% of the daily alowence, we need to multiply 200/250 by 10. We get 80. The picture shows a dubble number line for paper homework. Good luck!

Answer:

y = -2x + 4  

Step-by-step explanation:

We are given that a line has a slope (m) of -2 and passes through (5, -6).

We want to write the equation of the line.

There are three ways to write the equation of the line:

Any of these forms will work, however let's put it into slope-intercept form as that is the most common way.

As we are already given the slope, we can immediately plug that into the equation.

Substitute m with -2.

y = -2x + b

Now, we need to solve for b.

As the equation passes through (5, -6), we can use its values to help solve for b.

Substitute 5 as x and -6 as y.

-6 = -2(5) + b

Multiply.

-6 = -10 + b

Add 10 to both sides.

4 = b

Substitute 4 as b.

y = -2x + 4  

Answer:

C. The amount of gas left in Steve's car at his next visit to the gas

station is a function of the distance he drove.

Step-by-step explanation:

From the question, the car starts with a full tank of gas and the more the distance covered, the less gas will be left in the car at the next visit to the gas station.

The variables to take note are the distance travelled and the amount of gas left in the car at next visit to the gas station.

This means the farther he drives, the less gas will be left in the car because longer distances travelled consumes more gas in the car thus less gas will be left when the next visit to the gas station occurs.

Answer:

x=20

Step-by-step explanation:

Complementary = 2 angles which = 90 degrees

so 2x+10 + x+20 =90

combine like terms

3x+30=90

    -30  -30

3x=60

x=20

lets check!        (2(20)+10) + (20+20)

                           50       +        40  =90 degrees

Answer:

x = 20

angle 1 = 50

angle 2 = 40

Step-by-step explanation:

complementary angles add up to 90

so, you can make this equation:

2x + 10 + x + 20 = 90

combine like terms

2x + x + 10 + 20 = 90

3x + 30 = 90

subtract 30 from both sides of the equation

3x + 30 - 30= 90 - 30

3x = 90 - 30

3x = 60

divide both sides of the equation by 3

3x/3 = 60/3

x = 60/3

x = 20

now, plug x into the angles:

2x + 10

2 * 20 + 10

40 + 10

the first angle is 50°

x + 20

20 + 20

the second angle is 40
