Answer:

Option B

Step-by-step explanation:

For answering this question we must understand what is a function.

A function is different from mapping.

Mapping is just a subset of AxB where A and B are two sets.

But function is constrained to the point that elements of I set will have unique image in second set.

We find From the options

But in option B,, we find that 1 has two images 3.3 and 4.5.  i.e. 1 does not have unique image. Hence not a function.

All other options the first element in ordered pair have a unique image.

Hence all other options are functions.

Only option B is not a function.

The range is the difference between the highest number and the lowest number.

The lowest number is 5, the highest number is 13.

The range is 13 - 5 = 8 runs.

The correct answer for the range is: "5 to 13 runs" with a median of 8  and here is why:

The range of a set of numbers is what values could have or could be based on the lowest and highest values. The range is not the same as the average or the median. 5 runs was the least amount of runs that happened during one game and 13 was the most in another.

The average is calculated by adding all of the numbers added together and then divides by how many numbers that you added together.

The median is found by removing the lowest number and then the highest number. You repeat this process until you are left with only one number.

There are other things to find as well, but I think you understand now

Range: 5-13 ; 8

Average: 9

Median: 8

Also here is the definition from Dictionary.com on what range is:

range   rānj/Submit

noun

1.the area of variation between upper and lower limits on a particular scale.

ex: "the cost is thought to be in the range of $1-5 million a day"

The correct option is:   B.  length: 14 cm, width: 6.4 cm

Explanation

The actual length of Lake Superior is 350 miles and the width is 160 miles.

The scale is given as:  1 cm = 25 miles

Suppose, the length and width of the lake on the map are  [tex]x[/tex] cm and [tex]y[/tex] cm respectively.

First, the equation according to the ratio of scaled length to the actual length will be....

[tex]\frac{x}{350}=\frac{1}{25}\\ \\ 25x=350\\ \\ x=\frac{350}{25}=14[/tex]

Now, the equation according to the ratio of scaled width to the actual width will be....

[tex]\frac{y}{160}=\frac{1}{25}\\ \\ 25y=160\\ \\ y=\frac{160}{25}=6.4[/tex]

Thus, the length and width of the lake on the map will be 14 cm and 6.4 cm respectively.

Answer:

The value of k is 5.

Step-by-step explanation:

Since we know we can convert function's quadratic form to vertex form by completing the square.

f(x)=x2?6x+14

We will add and subtract 9 to our equation in order to complete the square.

[tex]1(x^{2} ?6x+9)-9+14[/tex]

Upon completing the square and combining like terms we will get,

[tex]1(x?3)^{2} +5[/tex]

Upon comparing Willie's vertex form with our expression we can see that k is 5.

Therefore, the value of k is 5.

The fraction is 7/8  is really close to 1, so you could estimate that the water level

changes by approximately -5 inches per month. The total change in the water

level at the end of the 3 month period would be approximately -15 inches.

Answer:

If the water level at the lake is decreased by the rate r each month, then the total change in water level at the end of the 3 month period is -3r.

Step-by-step explanation:

It is given that the water level at the lake continued to change at the same rate for 3 months in a row.

Let the water level at the lake is decreased by the rate r each month.

Change in the water level for 1 month period = -r units

Change in the water level for 2 month period = -2r units

Change in the water level for 3 month period = -3r units

So, we conclude that if the water level at the lake is decreased by the rate r each month, then the total change in water level at the end of the 3 month period is -3r.

Answer:

Connor ordered 5 toppings on his pizza.

Step-by-step explanation:

17.50 + (2.35 * x) = 29.25

Remove the parentheses

17.50 + 2.35x = 29.25

Subtract 17.50 from both sides

2.35x = 29.25 - 17.50

Subtract

2.35x = 11.75

Divide both sides by 2.35

x = 5

Answer:

29.25 - 17.50 = 11.75

11.75 divided by 2.35 = 5

So that he had 5 toppings on his pizza.

Step-by-step explanation:

To graph 24x + 25 = -6y + 7, first rearrange it to the form y = mx + b. In our case, y = -4x -3. Plot the y-intercept (0, -3) first, then use the slope (-4) to find a second point (1, -7). Connect these points to form the graph.

To graph the equation 24x + 25 = -6y + 7, the first step is to rewrite the equation in slope-intercept form, or y = mx + b, where m is the slope of the line and b is the y-intercept (where the line crosses the y-axis).

Add 6y to both sides of the equation 24x + 25 = -6y + 7 to get 6y = 24x + 25 - 7. Then, rearrange the equations and divide all terms by 6 to get y = -4x - 3.

Now, we can identify the slope and y-intercept. The slope (m) is -4 and the y-intercept (b) is -3. Using these, we can plot two points on a graph. The first point is the y-intercept which is at (0, -3), the point where the line crosses the y-axis.

The slope of -4 means for every step to the right on the x-axis, we go down 4 steps. Therefore, our second point would be at (1, -7). Connect these two points with a straight line, and you have graphed the equation.

The distance between A and B is d = |B - A|

We have d = 3 and A = 12.

[tex]|B-12|=3\iffB-12=3\ \vee\ B-12=-3\qquad|\text{add 12 to both sides}\\\\B=15\ \vee\ B=9[/tex]

[tex]\dfrac{7}{12}x-\dfrac{1}{3}=\dfrac{1}{2}+\dfrac{3}{8}\\\\LCM(12,\ 3,\ 2,\ 8)=24\\\\\text{multiply both sides by 24}\\\\24\cdot\dfrac{7}{12}x-12\cdot\dfrac{1}{3}=12\cdot\dfrac{1}{2}+24\cdot\dfrac{3}{8}\\\\2\cdot7x-8=12+3\cdot3\\\\14x-8=12+9\\\\14x-8=21\qquad|\text{add 8 to both sides}\\\\14x=29\qquad|\text{divide both sides by 14}\\\\x=\dfrac{29}{14}[/tex]

To solve the equation, convert all fractions to have the same denominator. Then simplify the equation, and finally divide the obtained number by the coefficient of x to get the value of x.

To solve the equation 7/12x-1/3=1/2+3/8, we first need to simplify both sides of the equation by converting all the fractions to have the same denominator, which, in this case, is 24.

So we obtain the equation:(14/24)x-8/24=12/24+9/24. After simplifying this equation, we get: (14/24)x = 29/24. Diving 29/24 by 14/24 will give us the value of x.

This process is very similar to the one used for solving linear equations, you must combine like terms and isolate the variable on one side of the equation to find the solution.
