y = total cost

x = the number of miles traveled

Rent a Truck: y = 0.20x + 40

[they rent a moving truck for $40(upfront charge) plus $0.20 per mile(x)]

Moving R Us: y = 1x or y = x

[they rent a moving truck for only $1.00 per mile(x) with not upfront charge]

To find when the cost will be the same, set the equations equal to each other:

[Rent a Truck = Moving R Us]

0.20x + 40 = x Subtract 0.20x on both sides

40 = 0.80x Divide 0.80 on both sides

50 = x x = 50 miles

[proof]

Rent a Truck:

y = 0.20x + 40 Plug in 50 for x

y = 0.20(50) + 40

y = 10 + 40

y = 50 $50

Moving R Us

y = x Plug in 50 for x

y = 50 $50

Answer:

x = 50 miles

Step-by-step explanation:

Equation One: y = 40 + 0.2x

Equation Two: y = $1x = x

All you need to do is equate the two ys which represent the total cost for each company. Your question is when are they equal? So make them equal, and you will find out.

x = 40 + 0.2x Subtract 0.2x from both sides of the equation.

x - 0.2x = 40 Combine like terms

0.8x = 40 Divide both sides by 0.8

0.8x/0.8 = 40/0.8

x = 50 miles.

BRAINLIEST AND 39 POINTS

You have 10 numbers to choose from, and you're choosing 4 from that pool. Order of the numbers matters, because having 1234 as a PIN is not the same having it be 1324, so we're counting the number of permutations of 10 digits taken 4 at a time. So there are

$4!\dbinom{10}4=4!C(10,4)=4!C^{10}_4=\dfrac{10!}{(10-4)!}=5040$

possible PINs that can be made.

Using the p-value rule, if a null hypothesis is rejected at a significance level of 0.01, it will ________ be rejected at a sign

igomit [66]

Answer:

<u>always</u>

Step-by-step explanation:

For this hypothesis test:

<u>The Decision rule: </u> To reject the null hypothesis $H_o$ if the p-value is lesser than < the significance level.

At the level of significance 0.01, the null hypothesis is rejected.

So, p-value < 0.01 and this typically shows that p-value is < 0.05.

Therefore, it will <u>always</u> be rejected at ∝ = 0.05

Find the value of x

AveGali [126]

Answer:

x = 120

Step-by-step explanation:

Since they are supplementary, they add up to 180 degrees.

So, you can say x + x/2 = 180

Then, you would solve it like an algebra problem.

Multiply both sides by 2

2x + x = 360

Simplify

3x = 360

Divide both sides by 3

x = 120

Mai uses Triangle A and says the slope of this line is `\frac{6}{4}.` Elena uses Triangle B and says no, the slope of this line

nikdorinn [45]

Answer:

I agree with both of them because they are both correct

Step-by-step explanation:

See attachment for complete question;

Slope (m) is calculated using the following formula:

$m = \frac{Rise}{Run}$

Where

$Rise = Vertical\ Distance$

$Run = Horizontal\ Distance$

From the attachment, we have the following:

Triangle A

$Rise = 6\ units$

$Run = 4\ units$

So:

$m = \frac{Rise}{Run}$

$m = \frac{6}{4}$

<em>In this case, Mai is correct:</em>

Triangle B

$Rise = 1.5\ units$

$Run = 1\ units$

So:

$m = \frac{Rise}{Run}$

$m = \frac{1.5}{1}$

$m = 1.5$

<em>In this case, Elena is also correct:</em>
