Let cheese pizza be c and mushroom pizza be m3c + 4m = 12.503c + 2m = 8.50

Subtract Equation 2 from Equation 1.

3c + 4m - 3c - 2m = 12.50 - 8.502m = 4.00m = $2.00(2) $2.00

Answer:

(2)  $2.00

Step-by-step explanation:

Jack's order

3 slices of cheese pizza and 4 slices of mushroom pizza = $12.50

Grace's order

3 slices of cheese pizza and 2 slices of mushroom pizza = $8.50

The difference between the two orders is 2 slices of mushroom pizza.

The difference between the cost of the two orders is:

$12.50 - $8.50 = $4.00

Therefore, 2 slices of mushroom pizza costs $4.00

So the cost of 1 slice of mushroom pizza is:

$4.00 ÷ 2 = $2.00

In the given question, to approach this, we should have a little understanding of what is a random variable. The random variable here is the distance travelled by the tee shots in a golf.

What is a Random Variable?

A random variable is a numerical description of the outcome of a statistical experiment. A random variable that may assume only a finite number or an infinite sequence of values is said to be discrete; one that may assume any value in some interval on the real number line is said to be continuous.

We are given two scenarios in which we are to identify the random variable here.

The number of hits for the players of a baseball teamThe distance travelled by the tee shots in a golf

In the above scenarios, the random variable here is the distance travelled by the tee shots in a golf. The reason is that we can never give an exact value the distance and would lead to an assumption of a finite number of value or an infinite sequence of values to determine this.

use the dots for one and two. what is the difference between the ranges


a. 20 points
b. 5 points
c. 10 points
d. 35 points

Answers

Answer:

a. 20 points

Step-by-step explanation:

Range = Largest given value - Smallest given value.

Identifying the range of test 1

Looking at the dot plot the lowest test grade appears to be 50 while the highest is 90.

So range of test 1 = 90 - 50 = 40

Identifying the range of test 2

Looking at the plot the lowest test grade appears to be 40 while the highest appears to be 100

So range = 100 - 40 = 60

Identifying the differences between the ranges

Test 1 range : 40

Test 2 range : 60

Difference between the two : 60 - 40 = 20 points

Answers

The height of the skyscraper is 201.5 meters, if the angle of elevation to the top of a prominent skyscraper to be 36º

What is trigonometry?

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

We have:

Angle of elevation = 36 degree

Horizontal distance of 275 meters from the base of the skyscraper

From the tan ratio:

tan36 = x/275

x = 275(tan36)

x = 199.79 meters

The height of the skyscraper = 199.79+ 1.69 = 201.48 ≈ 201.5 meters

Thus, the height of the skyscraper is 201.5 meters if the angle of elevation to the top of a prominent skyscraper to be 36º

The pole casts a 12-foot shadow when the sun is at a 40° angle of elevation. Which equation could Kim use to find x, the length of the pole?

Answers

Answer: Therefore the  length of the pole in  10.1 foot (approx) .

Step-by-step explanation:

To proof

As given

The pole casts a 12-foot shadow when the sun is at a 40° angle of elevation.

x represented the length of pole .

As shown in the diagram

By using the trignometric identity

tan40° = 0.839099631 ( approx )

x = 12 × 0.839099631

x = 10.1 foot (approx)

Therefore the  length of the pole in  10.1 foot (approx) .

The length of time it takes a worker to assemble a large product is assumed to be normally distributed. a random sample of 25 workers a were selected, and their times to assemble the product were recorded. the mean and variance for this sample were 3 and 0.5 hours, respectively.

the 90 percent confidence interval for the mean length of time (in hours) it takes a worker to assemble the product _____ hours to ______ hours

Answers

Using the t-distribution, it is found that the 90% confidence interval is of  2.71 hours to 3.29 hours.

What is a t-distribution confidence interval?

The confidence interval is:

[tex]\overline{x} \pm t\frac{s}{\sqrt{n}}[/tex]

In which:

[tex]\overline{x}[/tex] is the sample mean.t is the critical value.n is the sample size.s is the standard deviation for the sample.

The critical value, using a t-distribution calculator, for a two-tailed 95% confidence interval, with 25 - 1 = 24 df, is t = 2.0639.

The other parameters are given as follows:

[tex]\overline{x} = 3, s = \sqrt{0.5} = 0.707, n = 25[/tex]

Hence the bounds of the interval are given as follows:

[tex]\overline{x} - t\frac{s}{\sqrt{n}} = 3 - 2.0639\frac{0.707}{\sqrt{25}} = 2.71[/tex]

[tex]\overline{x} + t\frac{s}{\sqrt{n}} = 3 + 2.0639\frac{0.707}{\sqrt{25}} = 3.29[/tex]

h = 290-5t, where t is the time in hours. Which of the following
statements are true? Select all that apply.
the initial

Answers

Answer:

below

Step-by-step explanation:

• We know that the initial height of Candle A is 201 millimeters and of Candle B is 290 millimeters which means the first statement is not true.

• To find the rate at which the Candle A is decreasing, we simply have to divide 201 - 177 with 4.

24 / 4 = 6

       As we can see Candle A is decreasing at a faster rate of 6 than the rate of decreasing of Candle B which is 5. This means that second statement is true.

• To find out after how many hours will the Candle B burn out we simply have to divide the initial value with the rate of change which is 5.

290 / 5 = 58

       Candle B will burn out after 58 hours. This statement is true.

• We simply have to multiply the rate of change with 10 and after that subtract the value that we get from the initial value of Candle A.

10 x 6 = 60

201 - 60 = 141

After 10 hours the height of Candle a will be 141 millimeters. This statement is true.

• We know that Candle A is burning out at a faster rate and that the Candle B was higher at start which means that

       Candle A will burn out before Candle B. This statement is true.

Answer: $54.45

Step-by-step explanation:

      First, we will find the price of one towel.

-> We will divide the cost by the towels bought.

$39.60 / 8 = $4.95

     Now, we can find the price of 11 towels.

-> We will multiply the cost of one towel by 11 to find the total cost.

$4.95 * 11 = $54.45

Answer:

$54.45

Step-by-step explanation:

Given:

Number of towels = 8

Money spent on towels = $39.60

Can someone help me with the steps to create the formula? It involves quadratics​

Answers

The formula of the quadratic function passing through the points (-2,0), (8,0) and (2, -24) is f(x) = x² - 6x - 16

How to create the formula?

The points are given as:

(-2,0) , (8,0) and (2, -24)

The points (-2,0) and (8,0) are the zeros of the function.

So, we have:

f(x) = a(x + 2)(x -8)

Substitute (2, -24) in the above equation

-24 = a(2 + 2)(2 -8)

Evaluate the sum and the difference

-24 = a(4)(-6)

Divide both sides by -24

a = 1

Substitute a = 1 in f(x) = a(x + 2)(x -8)

f(x) = (x + 2)(x -8)

Expand

f(x) = x² + 2x - 8x - 16

Evaluate the like terms

f(x) = x² - 6x - 16

Hence, the formula of the quadratic function is f(x) = x² - 6x - 16

For a charity initiative, 420 t-shirts were made; in the morning 1/3 of the t-shirts is sold and in the afternoon 4/7 of the remaining ones. How many shirts are left to sell at the end of the day?

Answers

1/3 * 420 = amount of t-shirts sold in the morning

1/3 * 420 = 420/3 = 140 t-shirts

140 t-shirts were sold, so remaining is 420 - 140

420 - 140 = 280 remaining t-shirts

4/7 * 280 = amount of t-shirts sold in the afternoon

4/7 * 280 = (280/7) * 4 = 40 * 4 = 160 t-shirts

160 t-shirts were sold, so remaining is 280 - 160

the remaining t-shirts = 120 t-shirts

120 t-shirts are left to sell at the end of the day
