The difference of twice a number and seven is 17. Find the number.

Answer:

negative one over two is the right answer

Answer:

is 2 because 4 plus 3 equals 7 and c equals 3

The mathematical expression of the give algebraic expression is,

⇒ (c - 7) / 4

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The algebraic expression is,

'' The quotient of 7 subtracted from a number, c, and 4''.

Now,

Here, The algebraic expression is,

'' The quotient of 7 subtracted from a number, c, and 4''.

So, We can formulate;

''7 subtracted from a number c'' means that;

= c - 7

So, 'The quotient of 7 subtracted from a number, c, and 4' is written as;

⇒ (c - 7) / 4

Thus, The mathematical expression of the give algebraic expression is,

⇒ (c - 7) / 4

Answer: 2(x- 6)(x - 1)

Step-by-step explanation:

The equation that has a constant rate of change of 25 is

25x = y

Option B is the correct answer.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

We have,

A)

x + 25 = y

When x = 1, y = 26

When x = 2, y = 27

The constant rate of change.

= (27 - 26)/(2 - 1) = 1/1 = 1

B)

25x = y

When x = 1, y = 25

When x = 2, y = 50

The constant rate of change.

= (50 - 25)/(2 - 1) = 25/1 = 25

C)

x - y = 25

When x = 1, y = -24

When x = 2, y = -23

The constant rate of change.

= (-23 + 24)/(2 - 1) = 1/1 = 1

D)

5x = y

When x = 1, y = 5

When x = 2, y = 10

The constant rate of change.

= (10 - 5)/(2 - 1) = 5/1 = 5

Thus,

25x = y has a constant rate of change of 25.

Answer:

(about) 11.18034

Step-by-step explanation:

Use the distance formula to find the distance:

d = sqr (x2 - x1) + (y2 - y1)

Fill in the variables with what you know:

d = sqr ((6 - (-4)) + (2 - (-3)))

(Honestly it doesn't matter what order you put the x and y, as long as x2 and y2 make up the coordinates of one point and x1 and y1 make up the coordinates of the other)

 = sqr ((6 + 4)^2 + (2 +3)^2)

 = sqr ((10)^2 + (5)^2)

 = sqr (100 + 25)

 = sqr (125)

 = (about) 11.1803

Answer: MAD= 3

Step-by-step explanation:

Find the mean of the data set

31+24+32+28+29+36/6= 30

subtract EACH data by the mean, find the absolute value of the answer

31-30= 1 (absolute value)

24-30= 6 (absolute value)

32-30= 2 (absolute value)

28-30= 2 (absolute value)

29-30= 1 (absolute value)

36-30= 6 (absolute value)

Now find the mean of the values

1+6+2+2+1+6/6=3

Simplify again for 4(7-9): -8

Therefore,

-4> -8 The solution is true.  

#7 is B, the trapezoid is reflected across the x axis

#8 is C, unlike D, answer C is still the same shape as triangle A. Answer A is just the same triangle in the same position, can't tell if it moved or not bc it never showed us. B is a reflection, it's flipped.

#9 is D, nothing has changed except it's position; it's been moved to the right

#10 is C, the points of the triangle are at different positions, and it didn't look like it flipped over the x or y axis, so it's reflection. It's also moved to the right, so translation

Answer:

$58.50

Step-by-step explanation:

It is given that the student council pays

For per french fry = $0.85

For per soda fry = $1.20

Discount on the combo of  fries and soda = $0.75

Total revenue for one combo = $0.85 + $1.20 - $0.75 = $1.30

Since the total revenue for one combo is $1.30, therefore the total revenue for 45 combo is

Total revenue for 45 combo = 45 × $1.30 = $58.50

Therefore, they will make $58.50 if they sell 45 combos.

Answer:

(a) Let the probability drivers are drunk = P(D) = 0.08

The probability that drivers in the area never drink and drive, but are simply bad drivers = P(B) = 0.32

The probability that drivers in the area never drink and drive, and are good drivers = P(G) = 0.60

Let S = event that the police stops the driver.

(b) The probability that a randomly selected driver will be stopped at the checkpoint is 0.2016.

(c) The probability that a driver who is stopped at the checkpoint is drunk is 0.337.

Step-by-step explanation:

We are given that 8% of drivers on New Years' Eve have a blood-alcohol level that is above the legal limit. It is also known that 32% of drivers in the area never drink and drive, but are simply bad drivers. The remaining 60% of drivers never drink and drive and are good drivers.

At this particular checkpoint, the police stop 85% of the drunk drivers, stop 38% of the bad drivers, and stop 2% of the good drivers.

(a) Let the probability drivers are drunk = P(D) = 0.08

The probability that drivers in the area never drink and drive, but are simply bad drivers = P(B) = 0.32

The probability that drivers in the area never drink and drive, and are good drivers = P(G) = 0.60

Let S = event that the police stops the driver

These are the four events stated in the question.

(b) So, the probability that the police stop the drunk drivers = P(S/D) = 0.85

The probability that the police stop the bad drivers = P(S/B) = 0.38

The probability that the police stop the good drivers = P(S/G) = 0.02

Now, the probability that a randomly selected driver will be stopped at the checkpoint is given by = P(S)

    P(S) = P(D) [tex]\times[/tex] P(S/D) + P(B) [tex]\times[/tex] P(S/B) + P(G) [tex]\times[/tex] P(S/G)

             = (0.08 [tex]\times[/tex] 0.85) + (0.32 [tex]\times[/tex] 0.38) + (0.60 [tex]\times[/tex] 0.02)

             = 0.068 + 0.1216 + 0.012  

            = 0.2016

Hence, the probability that a randomly selected driver will be stopped at the checkpoint is 0.2016.

(c) Now, the probability that a driver who is stopped at the checkpoint is drunk is given by = P(D/S)

       P(S/W) =  [tex]\frac{P(D) \times P(S/D)}{P(D) \times P(S/D)+P(B) \times P(S/B)+P(G) \times P(S/G)}[/tex]

                    =  [tex]\frac{0.08\times 0.85}{0.08\times 0.85+0.32\times 0.38+0.60\times 0.02}[/tex]

                    = [tex]\frac{0.068}{0.2016}[/tex] = 0.337

Hence, the probability that a driver who is stopped at the checkpoint is drunk is 0.337.

Answer: 7 x 3 = 21
