Step-by-step explanation:

The equation line of the of the road in slope-intercept form is; y = 2·x - 10

The standard form of the equation of a line is Ax + Bx + C, where A, B, and C are constants and A and B are nonzero numbers.

The parameters for the new road are;

The road will be parallel to village way with points (0, 5), and (-4, -3)

The road will pass through the intersection  of Gray Dr and Canon Rd., which is the point with coordinates (3, -4)

Required; The equation of the road

Since the new road is parallel to Village Way, which has slope;

m = (5 - (-3))/(0 - (-4)) = 8/4 = 2

The slope of the new road will also be 2.

Let the equation of the new road be y = m·x + c, where m = 2 is the slope we just found. To find c, we use the fact that the road passes through the point (3, -4);

y - (-4) = 2 × (x - 3)

y = 2·x - 6 - 4 = 2·x - 10

y = 2·x - 10

Therefore, c = -10

Therefore, the equation of the new road in slope-intercept form, therefore is; y = 2·x - 10

Step-by-step explanation:

It is found that the Statement 1 is true. The Statement 2 is false. The Statement 3 is true.

Function is a type of relation, or rule, that maps one input to specific single output.

Given that V (T) represent the value of a bank account, and thousands of dollars, T years after the account is open at the bank.

The following statements can be considered true or false in the case;

V(0) = 2 means that the value of the bank account when it is opened is; $2000. Thus, it is TRUE

V(5) = 2.2 means that 2.2 years after the bank account is opened, its value is; $5000. Thus, it is FALSE

V(10) – V(5) = 0.4 means that the bank account grows by, $400 between 5 and 10 years after its opening. Thus, it is TRUE

The function takes the form as given below.

The missing value of y such that the point (1, y) is equidistant from the points (5, 1) and (10, - 3) is - 9.125.

In this problem we have two points that are equisdistant to a third point, then we must solve the following Pythagorean form:

(1 - 5)² + (y - 1)² = (10 - 1)² + (- 3 - y)²

16 + (y - 1)² = 81 + (- 3 - y)²

(y - 1)² - (- 3 - y)² = 65

(y² - 2 · y + 1) - (9 + 6 · y + y²) = 65

- 8 · y - 8 = 65

y = 73 / - 8

Answer:

x=4, y=3.

Step-by-step explanation:

Solving for x,

⟿ 3x-1=11

⟿ 3x=11+1

⟿ 3x=12

⟿ x=12/3

⟿ x=4.

Solving for y,

⟿ 5y=15

⟿ y=15/5

⟿ y=3.

Therefore, x=4 and y=3.

1) a. mean =  4.164 b. standard deviation = 0.7792
2) a. mean =  $20.82 b. standard deviation = $3.896

To calculate the mean of the number of hours, we multiply each possible value by its probability and then add them up,

Mean = (1)(0.229) + (2)(0.113) + (3)(0.114) + (4)(0.076) + (5)(0.052) + (6)(0.027) + (7)(0.031) + (8)(0.358) = 4.164

Therefore, the mean number of hours that cars are parked is approximately 4.164.

To calculate the standard deviation of the number of hours, we use the formula,

SD = sqrt[(1/n) * sum(p(x)*(x - mean)^2)]

where n is the sample size, p(x) is the probability of each possible value, mean is the mean of the distribution, and x is each possible value.

Plugging in the values,

SD = sqrt[(1/8) * ((1-4.164)^20.229 + (2-4.164)^20.113 + (3-4.164)^20.114 + (4-4.164)^20.076 + (5-4.164)^20.052 + (6-4.164)^20.027 + (7-4.164)^20.031 + (8-4.164)^20.358)]

SD = sqrt[(1/8) * (2.4212)]

SD = 0.7792

To calculate the mean and standard deviation of the revenue generated per car, we simply multiply the mean and standard deviation of the number of hours by the cost per hour:

Mean revenue per car = 4.164 * $5 = $20.82

Standard deviation of revenue per car = 0.7792 * $5 = $3.896

Answer:

QR = 7.6 cm

Step-by-step explanation:

By theorem of tangents drawn from an external point to a circle,

"Tangents drawn from an external point to a circle are equal in measure"

By this property,

PQ = PT = 3.8 cm

And PR = PT = 3.8 cm

Since, QR = PQ + PR [By segment addition postulate]

QR = 3.8 + 3.8

QR = 7.6 cm

The number of full revolutions that Liz's front wheel completed is  16,037 full revolutions.

First, we need to find the circumference of the wheel. The formula for the circumference of a circle is C = 2πr, where r is the radius of the circle. In this case, the radius of the wheel is 54 cm, so we can plug that into the formula:

C = 2π(54 cm) = 108π cm

Next, we need to convert the total distance traveled from kilometers to centimeters, so that we can divide by the circumference of the wheel in centimeters.

There are 100,000 centimeters in a kilometer, so we can multiply the distance traveled in kilometers by 100,000 to get the distance in centimeters:

54.82 km * 100,000 cm/km = 5,482,000 cm

Now we can divide the total distance traveled by the circumference of the wheel to find the number of full revolutions:

5,482,000c m / 108π cm = 16,037.35

So, Liz's front wheel completed approximately 16,037 full revolutions.

Linear equations are often organized in slope-intercept form: \(y=mx+b\)

To find a linear equation, we often first solve for the slope, and then solve for the y-intercept algebraically.

To find the slope of a perpendicular line, we must find the negative reciprocal of the slope of the reference line.

We're given:

1) Find the slope of the reference line

We can rewrite the reference line to be clearer in slope-intercept form:

\(y=-1x+0\)

This means that -1 is the slope.

2) Find the slope of the perpendicular line

The negative reciprocal of -1 is 1. Therefore, the slope of the perpendicular line is 1. Plug this into slope-intercept form:

\(y=x+b\)

3) Solve for the y-intercept of the perpendicular line

\(y=x+b\)

Plug in the given point (-8,2) and solve for b:

\(2=-8+b\\b=2+8\\b=10\)

Therefore, the y-intercept of the perpendicular line is 10. Plug this back into our original equation:

\(y=x+10\)

\(y=x+10\)

Sample space of randomly selecting a US state is 50, the probability that the US state begins with M is 4/25, and the probability that it doesn't begin with a vowel is 2/5.

a. What is the sample space?The sample space for randomly selecting one of the 50 US states is 50, i.e., the list of the 50 states.

b. What is the probability that it begins with M?The number of states that begin with M is 8. Therefore, the probability that the randomly selected US state begins with M is 8/50 or 4/25.

c. What is the probability that it doesn't begin with a vowel?There are 20 US states that don't begin with a vowel. Therefore, the probability that a randomly selected US state doesn't begin with a vowel is 20/50 or 2/5.

Randomly selecting a US state requires knowing the sample space, which in this case is 50. A sample space represents all possible outcomes of a random experiment. Therefore, the sample space for this problem represents the list of all 50 US states that can be randomly selected. The probability that a randomly selected US state begins with M can be calculated by dividing the number of states that begin with M by the total number of states. There are 8 US states that begin with M, hence, the probability of selecting a state that begins with M is 8/50 or 4/25. Finally, the probability that the randomly selected US state doesn't begin with a vowel is 20/50 or 2/5.

In conclusion, the sample space of selecting a US state randomly is 50, the probability that it begins with M is 4/25, and the probability that it doesn't begin with a vowel is 2/5.

The equation representing the given situation is, 250 = 70x + 35, where x is the number of cars washed by the company.

In the question, we are given that Scarlett made a profit of $250.00 with her mobile car wash company. She charged $75.00 per car wash and received $35.00 in tips, but also had to pay $5.00 in cleaning supplies per car.

We are asked to represent the situation with an equation.

We assume the number of cars washed by the company to be x.

Charge for washing 1 car = $75.00.

Cost for cleaning supplies for 1 car = $5.00.

Thus the profit on the wash of 1 car = $75.00 - $5.00 = $70.00.

The total profit received by the company, on washing x number of cars = $70x.

The tips received = $35.00.

Thus, the total profit of the company = $(70x + 35).

But, the total profit is given to be $250.00.

Thus, we get an equation, 250 = 70x + 35.

Thus, the equation representing the given situation is, 250 = 70x + 35, where x is the number of cars washed by the company.
