the final exam for miguel's math class is worth 120 points and will be comprised of an assortment of 50 multiple choice and free response question. each multiple choice is worth 2 points and each free response question is worth 3 points

Data set 2 is not a function, while data set 1 is a function. To turn the data set that is not a function into a function, the point (3,0) can be changed so the x-value is not equal to 1, 3, 5 or 7.

To verify whether a relation represents a function, we need to observe if each input is mapped to only one output.

In input-output format, the points in these relations are given as follows:

(x,y).

Hence a data-set will represent a function if each value of x is mapped to a single value of y.

This means that data-set 1 represents a function, while data-set 2 does not, as the value of x = 3 is mapped to both y = 2 and y = 0.

The data-set 2 will represent a function if one of the x-coordinates of 3 is changed to another x-coordinate, that is also different of the other x-coordinates of the table.

The next year's population will be 140,014. The solution has been obtained by using arithmetic operations.

What are arithmetic operations?

For all real numbers, there are four fundamental mathematical operations that are:

1. The sum of the numbers is achieved through addition ('+').

2. Subtraction with the sign "-," which yields the numbers' differences.

3. Multiplication('×') when the result is the product of the numbers.

4. Division ('÷'), which yields the numbers' quotient.

We are given that the population of a city increases by 2.2% per year and this year's population is 137,000.

Let the population of next year be 'x'

A vertex (plural: vertices) is a point where two or more line segments meet. It is a Corner.

The width and length of the rectangle is 4.5ft and 12ft.

Width of a rectangle = b = x ft.

If the graph only touches the x-axis at the x-intercept, then it is said to "touch" the x-axis. This indicates that the graph does not pass through the x-axis at the x-intercept, but rather just touches it.

The x-intercept of a graph is the point at which the graph crosses the x-axis. It is also known as the abscissa. The x-coordinate of the x-intercept is the value where the graph intersects the x-axis.

The x-intercept of a graph is the point at which the graph crosses (or, in some cases, touches) the x-axis. A graph can have one or more x-intercepts. If the graph only crosses the x-axis once, then it has only one x-intercept. If the graph crosses the x-axis twice or more, then it has multiple x-intercepts. In either case, the x-intercepts can be described as either "crosses" or "touches" the x-axis.

These are the specified parameters:

Radius (r) = 5.1 m

Cone height (h) = 10.9 m

Find the length of the cone painter's line (s)

A function can be obtained from the table provided with the values of x and y in the form of a y=mx+b equation.

The above equation can be solved by plotting the graph or from table itself and after calculating its y-intercept, the value of y in the form of y= mx+ b can be obtained. Suppose the table has values of x and y as follows:

x: 0   1   2  3

y: 2  4   6  8

However, it can be seen that when x=0, y= 2, so the y-intercept i.e. the value of y obtained at x=0 is 2. And the slope can be calculated as:

Answer: 25q and 3d

Step-by-step explanation:

23 dimes and 17 quarters equal $6.55.

To find the number of dimes and quarters which equals $6.55, we can use the following method:

Let D = number of dimes

Let Q = number of quarters

40 coins  ==>  D + Q = 40  ==>  D = 40 - Q

$6.55 total  ==>  10*D + 25*Q = 655

After the value for D is substituted in the second equation,

10*(40 - Q) + 25*Q = 655

400 - 10*Q + 25*Q = 655

15*Q = 255

Q = 17

i.e., D = 40 - 17 = 23

Check:  23 dimes = $2.30

           17 quarters = $4.25

           Total = $6.55 

Therefore, 23 dimes and 17 quarters equal $6.55.

Answer:

Step-by-step explanation:

Unfortunately, without more information, it is not possible to accurately predict the number of pounds someone would be overweight if they spent 8 hours per day using a computer. The graph provided does not provide enough data to make an accurate prediction. It is possible, however, to make an educated guess based on the graph. Looking at the graph, it appears that someone who spends 8 hours per day on the computer would likely be somewhere between 20 and 40 pounds overweight.

I) we can substitute x + d = 2x + 1 and x + 2d = 11 into the equation for d:

x - 1 = 2x + 1 - x = 2x - x + 1 = x + 1

x = 0

II) The 30th term of this arithmetic sequence is 29.

To solve this problem, we can use the fact that in an arithmetic sequence, the difference between consecutive terms is constant.

(i) Let's call the common difference d. Then we can set up the equation:

x + d = 2x + 1

d = x - 1

Since we know that x; 2x + 1; 11 are three consecutive terms of an arithmetic sequence, we can substitute x + d = 2x + 1 and x + 2d = 11 into the equation for d:

x - 1 = 2x + 1 - x = 2x - x + 1 = x + 1

x = 0

(ii) To find the 30th term, we can use the formula for the nth term of an arithmetic sequence:

an = a1 + (n - 1)d

where a1 is the first term, d is the common difference, and n is the number of the term we want to find.

Substituting the known values into this formula:

a30 = x + (30 - 1)d

a30 = 0 + (29)(1)

a30 = 29

So the 30th term of this arithmetic sequence is 29.

$60 / 6 barbecue sticks = $x / 1 barbecue stick

Where x is the value of 1 barbecue stick.

To find the value of x, we can cross-multiply and divide by 6:

$60 = 6 barbecue sticks * $x/1

$60 = $6x

$x = $10

So, $10 will equal 1 barbecue stick, if $60 = 6 barbecue sticks.

We know that you earned $300, so we can substitute that into the proportion:

$60 / 6 barbecue sticks = $300 / n barbecue sticks

We can cross-multiply and divide by 60:

6 barbecue sticks * $300 = $60 * n barbecue sticks

n barbecue sticks = $300 * 6 / $60

n barbecue sticks = 30

Therefore, you sold 30 barbecue sticks.

The probability of getting 1st even and second odd is 9/36 = 1/4

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has included probability to forecast the likelihood of certain events. The degree to which something is likely to happen is basically what probability means. You will understand the potential outcomes for a random experiment using this fundamental theory of probability, which is also applied to the probability distribution. Knowing the total number of outcomes is necessary before we can calculate the likelihood that a certain event will occur.

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can vary from 0 to 1, with 0 being an impossibility and 1 denoting a certainty. For pupils in Class 10, probability is a crucial subject since it teaches all the fundamental ideas of the subject. One is the sum of the probabilities of all the events in a sample space.

Number of outcomes with 1st even and second odd is 9

Total number of outcomes = 36

Consequently, the yield to maturity of a P7000 bond purchased at 90 with 15 years left to maturity is approximately 6.769%.

The rate of return an investor will receive if they hold the bond until maturity is known as the yield to maturity (YTM) of the bond. We need to know a bond's face value, coupon rate, market price, and time until maturity in order to determine its YTM.

Here,

Given :

Face value (FV) equals P7,000

Discount rate is 6%.

Market price as of today (CP) is $90.

15 years is the time to maturity (T).

To determine the YTM, we can use the bond pricing formula:

CP is equal to (FV * C) / (1 + r)T plus (FV / (1 + r)T)

Where:

(FV * Coupon Rate) / 2r = YTMT = time to maturity in years, where C is the annual coupon payment.

The result of solving the equation is 6.769% for the YTM.
