A group of friends wants to go to the amusement park. They have no more than $425 to spend on parking and admission. Parking is $14.75, and tickets cost $18.75 per person, including tax. Which inequality can be used to determine x, the maximum number of people who can go to the amusement park? 425 18.75(x + 14.75), 425 14.75 +18.75x 4252 14.75 +18.75, 425 18.75(x + 14.75)​

Answers

Answer:

14.75 + 18.75x ≤ 425

Step-by-step explanation:

Total amount they have is $425

Parking for the entire group = $14.75

If x is the number of persons in the group, the cost of x tickets at $18.75 per head
= 18.75x

The total cost incurred
= Parking Cost + Ticket Cost

= 14.75 + 18.75x

This has to be less than equal to 425

So the inequality is

14.75 + 18.75x ≤ 425

Apply the Empirical RuleA 3-column table has 1 row. The first column is labeled Age with entry 7 years. The second column is labeled Mean with entry 49 inches. The third column is labeled Standard Deviation with entry 2 inches. According to the empirical rule, 68% of 7-year-old children are between inches and inches tall.

Answers

The empirical norm therefore states that 68% of 7-year-old kids are between 47 and 51 inches tall.

What does a table column mean?

A column in a table is a collection of cells which are arranged vertically. A field, like the received field, is a sort of element that contains only one item of data. A column in a table usually contains the values for just a single field.

The empirical rule states that in a normal distribution, 68% of the data fall within one average standard deviation. In this instance, the mean difference is 2 inches, while the average height of 7-year-old kids is 49 inches.

We must identify the range among heights that is within one average standard deviation in order to apply the scientific rule. To accomplish this, we can add and subtract the standard variance from the median as follows:

Mean ± (Standard Deviation) = 49 ± 2

As a result, the height range which falls within the standard deviation from the average is between 47 and 51 inches.

What is the height (in inches) of a triangle with an area of 720
square inches and base of 32 inches?

Answers

The height (in inches) of a triangle with an area of 720 square inches and base of 32 inches is 45 inches.

The height of a triangle can be found using the formula for the area of a triangle: A = (1/2)bh, where A is the area, b is the base, and h is the height.

In this case, we are given the area (720 square inches) and the base (32 inches) and are asked to find the height.

First, we can plug in the given values into the formula:

720 = (1/2)(32)(h)

Next, we can simplify the equation by multiplying both sides by 2:

1440 = 32h

Finally, we can solve for the height by dividing both sides by 32:

h = 45 inches

Therefore, the height of the triangle is 45 inches.

On a certain route, an airline carries 9000 passengers per month, each paying $150. A market survey indicates that for each$1 decrease in the ticket price, the airline will gain 50 passengers. Express the monthly revenue for the route, R, as a function of the ticket price, x.

Answers

The monthly revenue for the route, R, as a function of the ticket price, x, can be expressed as R(x) = (9000 + 50(150 - x))x.

The airline carries 9000 passengers per month, and each pays $150, so the initial monthly revenue is R(150) = 9000 x $150 = $1,350,000.

If the ticket price is decreased by $1, the airline will gain 50 passengers, so the new monthly revenue can be calculated by adding the revenue gained from these additional passengers to the initial revenue, and subtracting the revenue lost from the decrease in ticket price. The revenue gained from the additional passengers is 50(x - $150), since each passenger pays the new ticket price x instead of $150. The revenue lost from the decrease in ticket price is 9000($150 - x), since each of the 9000 passengers pays $150 - x instead of the initial price of $150.

Putting these together, we get:

[tex]R(x) = R(150) + 50(x - $150) - 9000($150 - x)[/tex]

R(x) = (9000 x $150) + 50x - 50($150) - 9000($150) + 9000x[tex]R(x) = R(150) + 50(x - $150) - 9000($150 - x)[/tex]

[tex]R(x) = (9000 + 50(150 - x))x[/tex]

Thus, the monthly revenue for the route, R, as a function of the ticket price, x, is [tex]R(x) = (9000 + 50(150 - x))x[/tex]

Looking at the bookshelf in the library Neil notices that the number of books that he
has read is

of the books he did not read. If he reads one more book from the
bookshelf and puts it back this fraction becomes 1. How many books are there on
the bookshelf?
6

Answers

There are 14 books on the bookshelf as a result.

How was the number of books on the shelf determined?

Assume that there are x total books on the bookshelf. Neil has read 7 out of a total of 7 + (x-7) = x-0 books, which means that he has read 7/14 of the books, according to the problem. This is reduced to 1/2.

Now that he has read 8 out of 15 books, his percentage of books read will be 8/15 if he reads one more (the original 7 books he read plus the one he read now). This implies:

8/15 = 8/(x+1)

In order to find x, we can cross-multiply:

8(x+1) = 15(8) (8)

8x + 8 = 120

8x = 112

x = 14

There are 14 books on the bookshelf as a result.

Answers

Answer:

Alice paid for the 4 packs of cards with 4 x $2 = $8.

She used 3 ten dollar bills, which is 3 x $10 = $30.

Therefore, the cost of the 2 jigsaw puzzles is:

Total cost of the purchase - Cost of the packs of cards

= ($30 + $4 change) - $8

= $26

So, the total cost of the 2 jigsaw puzzles was $26.

The answer is (D) $26.

Answer:

The equations y1 = 2x + 1 and intersect at a point. After three cycles of successive approximation, without rounding the answers, the approximate x-value of the point of intersection is

Answers

The intersection point on the graph has an approximate x-value of 1a.

Describe graphs?

Making the curve that represents a function on a coordinate plane is the process of graphing a function. If the curve (or graph) represents the function, then each point on the curve will satisfy the function equation.

The line, also called the "curve," has a point at each point that fulfils the function.

The three lines are contemporaneous if they all cross at the same point.

From the second equation,

x = 8y + 19

Putting value of x,

2(8y + 19) + 3y = 0                              9(8y + 19) + 5y = 17

16y + 38 + 3y = 0                                 72y + 171 + 5y = 17

19y = -38                                                77y = -154

 y = -2                                                      y = -2

You'll see that the y value for the answer is the same for the two equations. Simply evaluate the second equation now to find x. Hence, we are aware that the y-coordinate is negative two at some x number.

x = 8(-2) + 19

x = -16 + 19

x = 3

The single point that these three equations share is (3, -2).

4x - 3y = 13                     eq1

-6x + 2y = -7                   eq2

Use the elimination method. Multiply eq1 by eq2 and multiply eq2 by eq3.

8x - 6y = 26                eq1

-18 + 6y = -21              eq2

Adding the equations to eliminate the y terms.

-10x = 5

 x = -1/2

Substituting this value of x into any of the equations to solve for the value of y.

Substituting the first equation into the second equation. In terms of x, this will translate the second equation. From that freshly created equation, find x. Once you solved for x, substitute that value of x into the first equation to solve for y.

You have a vertical line that passes all points that have the x coordinate 7 and you have a horizontal line that passes all point that have the y coordinate -5.

If you were to graph these two lines, they will be intersecting at (7, -5).

Now, draw the following lines on a coordinate system:

i) A vertical line passing through the points (3, 0).

ii) A horizontal line passing through the point (0, 6).

iii) A line passing through the points (0,0) and (1, -3).

Once you have drawn these lines, look for 3 points of intersection.

Area = (base × height) / 2

Lines that have the same slope never intersect.  Put both equations in y=mx+b  form where the slope is the coefficient of x.

2x + 3y = > 3y = -2x + 23

y = (-2 / 3) x + 23/3

7x + py = 8

py = -7x + 8

y = (-7 / p) x + 8/p

Set the slopes equal to each other.

-2 / 3 = -7 / p

Look for a pattern in the table. Find the missing addends and sums

Answers

Looking at the table, we can see that the addends follow a pattern where each subsequent pair of addends adds up to 1/5. Specifically, the missing addend is 2/5 - 3/10, which equals 1/10. The missing sums are 1/2 and 4/10.

The addends in the table are as follows:

1/10 + 1/5 = 3/10, 1/5 + 1/5 = 2/5

3/10 + 1/5 = 1/2

We can observe that the first two pairs of addends add up to 1/5 less than the subsequent sums. This pattern indicates that the missing addend must be

1/5 - 1/10 = 1/10

which would make the third pair of addends add up to

1/2 - 1/10 = 4/10

Therefore, the missing sums are 1/2 and 4/10, respectively. This pattern can be helpful in solving similar problems where pairs of addends add up to a specific sum or difference.

Sharon is interested in learning about the returns to schooling. She finds a dataset with information on earnings, education, gender, age, experience and quarter and year of birth collected from a random sample of individuals. She uses this data to estimate the following Mincer earnings regression using ordinary least squares: Log Y = a + b*S + c*female + d* experience + h*experience2+u Where S is the individual's years of schooling; female takes the value of 1 if the individual is female and 0 if female. Experience is in years. The Table below provides the coefficients and standard errors that she obtained. Coefficient Std error a 6.561 2.650 b 0.074 0.025 c -0.121 0.041d 0.075 0.033 h -0.021 0.013 a) Sharon shows you this table and asks for your help in interpreting the coefficients. From this table, what is the magnitude of the OLS estimate of the return to an additional year of schooling? Is this statistically significant at the 5% level of significance? Note that the critical value for the t-distribution for a two- sided test with 5% level of significance is 1.96. (10 marks) b) Sharon thinks that this is the true return to schooling. Is she correct?
