Answer:

d=4

Step-by-step explanation:

Agency 1:

Total cost of renting a car=24.50d + 15.99

Agency 2:

Total cost of renting a car=27.50d + 3.99

Where, d=No. of days of renting the car

Which equation could be used to find the number of days, d, at which the rental fee is the same for both agencies?

The equation is by equating agency 1 and agency 2 equation

24.50d + 15.99 = 27.50d + 3.99

Collect like terms

24.50d - 27.50d = 3.99 - 15.99

-3d = -12

Divide both sides by -3

d= -12 / -3

=4

d=4

Check

Agency 1:

24.50d + 15.99

= 24.50(4) + 15.99

= 98 + 15.99

= 113.99

Agency 2:

27.50d + 3.99

= 27.50(4) + 3.99

= 110 + 3.99

= 133.99

Answer:

24.5d + 15.99 = 27.5d + 3.99

Answer:

(x + 87)/4

Step-by-step explanation:

"a quarter" = 0.25 by numerical value.

"the sum of a number (x) and 87" = x + 87

Combine the two terms:

"the sum of a number (x) and 87" + "a quarter of the sum..." = (x + 87) * 0.25 = (x + 87)/4

(x + 87)/4 is your answer.

Answer:

t = [tex]\frac{1}{5}[/tex]

Step-by-step explanation:

Since the points are collinear they lie on the same line.

Thus the slopes between any of the 3 points are equal.

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 8, 5) and (x₂, y₂ ) = (2, - 1)

m = [tex]\frac{-1-5}{2+8}[/tex] = [tex]\frac{-6}{10}[/tex] = - [tex]\frac{3}{5}[/tex]

Repeat using

(x₁, y₁ ) = (- 8, 5 ) and (x₂, y₂ ) = (0, t) and equate to previous m

m = [tex]\frac{t-5}{0+8}[/tex] = [tex]\frac{t-5}{8}[/tex] = - [tex]\frac{3}{5}[/tex] ( cross- multiply )

5(t - 5) = - 24 , that is

5t - 25 = - 24 ( add 25 to both sides )

5t = 1 ( divide both sides by 5 )

t = [tex]\frac{1}{5}[/tex]

Answer:

EF = 2 units

Given:

Line segment DF and point E on it.

DF = 11 unit

DE = 9 Unit

Find:

EF

Computation:

We know that,

DF = DE + EF

11 = 9 + EF

EF = 11-9

EF = 2 units

Answer:

D; b = -20.75

Step-by-step explanation:

Here in this question, we want to find solution to the given linear equation.

The linear equation is;

-83 = b4

Now, to find the value of b, we will need to divide both sides by its coefficient.

Looking at the question, the coefficient of b is 4

Mathematically, that would be :

-83/4 = b4/4

b = -83/4

b = -20.75

Answer:

b = -20.75

Step-by-step explanation:

Given:

-83 = b4

It can also be written as

-83 = 4b

divide both sides by the coefficient of b which is 4

-83 / 4 = 4b / 4

-20.75 = b

Therefore,

b = -20.75

Check:

-83 = b4

-83 = -20.75(4)

-83 = -83

Answer:

The answer for this question is A

Answer:

A

Step-by-step explanation:

● -7x > 21

Divide both sides by 7

● -7x/7 > 21/7

● -x > 3

Multiply both sides by -1 and switch the sign since you have multiplied by a negative number.

● x < -3

The representation is A since -3 is represented by an empty dot ○ wich means it's out the solutions

The solution to the given inequality -7x/7 > 21/7 is x < -3 which is the correct answer that would be option (A).

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

The inequality is given in the question

⇒ -7x > 21

Divide both sides by 7 both sides of the above inequality

⇒  -7x/7 > 21/7

⇒  -x > 3

Multiply both sides by -1 and because we multiplied by a negative quantity, flip the sign.

⇒  x < -3

The representation is A because -3 is represented by an empty dot which shows the solution of the graph.

The required graph has been attached which represents the solution to the given inequality -7x/7 > 21/7 is x < -3

Hence, the correct answer would be an option (A).

Arranging the data in ascending order:

8 , 8 , 10 , 11 , 13 , 13 ,13 , 14 , 14 , 15 , 16 , 17 , 18 , 18 ,

In the case of discrete data, mode can be found just by inspection, i.e just by taking an item with highest frequency.

Here, 13 has the highest frequency

So, Mode = 13

Step-by-step explanation:

A student divided the given number by 100 that resulted to 28.003 in his chart. So what we are looking for in the given situation is that the value of the number before it was divided by 100.

To get the desired value, we can simply multiply the obtained result by 100

=> 28.003 x 100

=> 2800.3

So, by dividing 100 to the given number, we simply move the value to the right in a value of hundreds.

Answer:

The correct option is a.

Step-by-step explanation:

The standard deviation of the sampling distribution of sample mean ([tex]\bar x[/tex]) is known as the standard error. It is denoted by [tex]\sigma_{m}[/tex].

The formula to compute the standard error is:

[tex]\sigma_{m}=\frac{\sigma}{\sqrt{n}}[/tex]

As the population standard deviation is divided by the square root of the sample size, the standard error can never be more than the population standard deviation, σ.

Also, since the population standard deviation is directly proportional to the standard error, the value of [tex]\sigma_{m}[/tex] is affected by the value of σ.

And since the sample size is inversely proportional to the standard error, the value of [tex]\sigma_{m}[/tex] decreases as the value of n increases.

The sample mean is a statistic, i.e. it represents a specific characteristic (here, the average) of the sample.

The standard deviation of any statistic measures the variability of the statistic.

So, the standard error measures the variability in sample means.

Thus, the correct option is a.

Answer:

The triangle is not equilateral.

Step-by-step explanation:

Distance formula:

[tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

Distance from (a, a) to (-a, -a):

[tex] d_1 = \sqrt{(-a - a)^2 + (-a - a)^2} [/tex]

[tex] d_1 = \sqrt{(-2a)^2 + (-2a)^2} [/tex]

[tex] d_1 = \sqrt{8a^2} [/tex]

Distance from (-a, -a) to (-3a, 3a):

[tex] d_2 = \sqrt{(-3a - (-a))^2 + (3a - (-a))^2} [/tex]

[tex] d_2 = \sqrt{(-2a)^2 + (4a)^2} [/tex]

[tex] d_2 = \sqrt{20a^2} [/tex]

Distance from (-3a, 3a) to (a, a):

[tex]d_3 = \sqrt{(-3a - a)^2 + (3a - a)^2}[/tex]

[tex]d_3 = \sqrt{(-4a)^2 + (2a)^2}[/tex]

[tex]d_3 = \sqrt{20a^2}[/tex]

The three sides do not have the same length, so the triangle is not equilateral.
