Answer:

A. 16

Step-by-step explanation:

We have to find rate of change of function from x=3 to x=5

The average rate of change for the interval a≤x≤b is given by:

Rate of change=  (f(b)-f(a))/(b-a)

In our question,

a=3

and

b=5

We can see from the table that at x = 3, the value of function is 18

So,

f(a)=18

and

At x=5, the value of function is 50

f(b)=50

Rate of change=(50-18)/(5-3)

=32/2

=16

So the rate of change of function between x=3 and x=5 is 16 ..

The median is 133.5, the first quartile is 128, the third quartile is 139, and the interquartile range is 11.

It is the middle value of the given set of numbers after arranging the given set of numbers in order.

We have,

To find the median, first we need to order the data set from least to greatest:

106, 127, 129, 132, 135, 138, 140, 158

There are 8 data points, so the median is the average of the 4th and 5th numbers:

Median = (132 + 135) / 2 = 133.5

To find the quartiles, we need to divide the data set into four equal parts. Since there are 8 data points, the first quartile (Q1) is the median of the first half of the data set, and the third quartile (Q3) is the median of the second half of the data set.

Q1 = median of {106, 127, 129, 132} = (127 + 129) / 2 = 128

Q3 = median of {135, 138, 140, 158} = (138 + 140) / 2 = 139

The interquartile range (IQR) is the difference between the third quartile and the first quartile:

IQR = Q3 - Q1 = 139 - 128 = 11

Therefore,

The median is 133.5, the first quartile is 128, the third quartile is 139, and the interquartile range is 11.

Final answer:

The median of the given data set is 133.5, with the first quartile (Q1) at 128 and the third quartile (Q3) at 139. The interquartile range (IQR) is 11, and the range is 52.

Explanation:

To find the median, first quartile (Q1), third quartile (Q3), and interquartile range (IQR) of a set of data, we first need to list the data in ascending order. The given data is: 106, 127, 129, 132, 135, 138, 140, 158.

The median is the middle number when the data set is ordered. Since there are 8 numbers, the median will be the average of the 4th and 5th numbers: (132 + 135) / 2 = 133.5. So the median is 133.5

To find the first quartile, which is the median of the lower half of the data (excluding the median if the number of data points is odd), we look at the first four numbers: 106, 127, 129, 132. The median of this subset is (127 + 129) / 2 = 128. So Q1 is 128.

Similarly, Q3 is the median of the upper half of the data. For the numbers 135, 138, 140, 158, the median is (138 + 140) / 2 = 139. So Q3 is 139.

The IQR is the difference between Q3 and Q1, so IQR = 139 - 128 = 11.

The range of the data is the difference between the max and min values, which is 158 - 106 = 52.

QUES 1)

Let x denote the gig of data used.

and y denote the monthly charge for use of data

We know that the equation of a line with given slope "m" and y-intercept "c" is given by:

       y=mx+c

Runfast--

The monthly charge is: $ 8

and the cost of per gig of data is: $ 8

Since, the cost per gig represent the slope and fixed monthly charge represent the y-intercept.

Hence, the equation that is given by this set of information is:

             [tex]y=8x+8---------(1)[/tex]

BA & D--

The monthly charge is: $ 15

and the cost of per gig of data is: $ 4

Hence, the equation that is given by this set of information is:

             [tex]y=4x+15-----------(2)[/tex]

QUES 2)

We will substitute the value of y from equation (1) in equation (2) as follows:

 8x+8=4x+15

i.e.  8x-4x=15-8

i.e.   4x=7

i.e.   x=7/4=1.75

and the value of y is:

y=8×1.75+8

i.e.    y=22

Hence, the cost of both the companies are equal when 1.75 gigs of data is used and the cost is: $ 22

Answer:

12 5 dollar bills

20 50 dollar bills

Step-by-step explanation:

Let x = number of five dollar bills

Let y = number of fifty dollar bills

We have a total of 32 bills

x+y = 32

The total amount is 1060

5x+50y = 1060

We have 2 equations and 2 unknowns

x+y = 32

5x+50y = 1060

Multiply the first equation by -5 so we can eliminate x

-5x -5y = -5*32

-5x -5y =-160

Add this to the second equation

5x+50y = 1060

-5x -5y =-160

------------------------

45 y    = 900

Divide each side by 45

45y/45 = 900/45

y = 20

There are 20 50 dollar bills

x+y = 32

x+20 = 32

Subtract 20 from each side

x+20-20 = 32-20

x = 12

There are 12 5 dollar bills

Answer:

Given graph represents function.

Step-by-step explanation:

We have been given a graph. Now we need to find if the given graph represents function or not.

To check if any graph represents function or not, we apply vertical line test. That means if there exists any vertical line that crosses the given graph more than once then the given graph is not a function.

Now if you draw vertical lines then you won't find any such vertical line which crosses graph more than once.

Hence given graph represents function.

Answer:

[tex]f(x=\sqrt{x}-2[/tex].

Step-by-step explanation:

We have been given graph of a function. We are supposed to find the function formula.

Upon looking at our given function, we can see that it is transformed form of a square root function.

We know that square root parent function is in form [tex]f(x)=\sqrt{x}[/tex].

We can see that our given graph is shifted down along y-axis. The rule for shifting a graph down along y-axis is: [tex]f(x)\rightarrow f(x)-a[/tex], where graph of [tex]f(x)[/tex] is shifted down by a units.

So our function will be in form [tex]f(x=\sqrt{x}-a[/tex].

From our attached file, we can see that value of 'a' is 2.

Therefore, our required function would be [tex]f(x=\sqrt{x}-2[/tex].

Answer:

x > 12

Answer for 2/3>8

Answer:

x within the domain (-∞,0) ∪ (0,1/12) ∪ (1/6,∞)

Step-by-step explanation:

Let's find the solution by modifying the conditions like this:

First condition:

2/3x > 8

Notice that x needs to be a positive number because if x is negative number the expression 2/3x is always negative, and the given condition will be false. Also, x can't be 0 because dividing by 0 is not allowed.

Multiplying the first condition in both sides by (3x/2) we obtain:

(2/3x)*(3x/2) > 8*(3x/2) equal to:

1 > 12x, which dividing by 12 in both sides is:

1/12 > x, which means a domain: (0,1/12)

Second condition:

2/3x < 4

Notice that if x is negative, the expression (2/3x) is always negative, so the second condition will be always true, so negative numbers are not a problem for this conditions.

Let's find the highest positive number which allows the second condition to be a true statement.

Multiplying the second condition in both sides by (3x/2) we obtain:

(2/3x)*(3x/2) < 4*(3x/2) equal to:

1 < 6x, which dividing by 6 in both sides is:

1/6 < x which means a domain: (-∞,0) ∪ (1/6,∞), notice that 0 is not in the domain because dividing by 0 is not allowed, but also as mentioned before negative numbers makes the statement true.

Notice that the problem uses the word OR (condition one or condition two), which means that we need to create a domain for x which allows that always at least one condition is true.

Adding the x domains for the two conditions we obtain:

(-∞,0) ∪ (0,1/12) ∪ (1/6,∞); notice that all the boundary numbers are not included.

In conclusion, the statement 2/3x>8 or 2/3x<4 is true for x within the domain (-∞,0) ∪ (0,1/12) ∪ (1/6,∞).

ANSWER

B. Domain is (-∞,∞) and Range is (-∞,∞).

The given function is

[tex]f(x) = \sqrt[3]{x - 6} + 5[/tex]

This is function is obtained by shifting the base cubic root function 6 units to the right and 5 units up.

This function is defined for all real values of x.

Therefore the domain is all real numbers.

The range is all real numbers.

The domain for this function becomes the range for the inverse function and the range becomes the domain.

Hence the domain is (-∞,∞) and the range is (-∞,∞).

Given that PQ = QR, JK = 3x + 23, and LM = 9x - 19, we can find PK by adding JK and LM together since they are all part of the same line. So, PK = JK + LM = (3x + 23) + (9x - 19). Now simplify the expression by combining like terms: PK = 3x + 9x + 23 - 19 = 12x + 4.
