Answer:

the answer would be c.

Step-by-step explanation:

in order to be a function the x axis cannot repeat itself. after process of elimination you are left with c which is the only option in which x does not repeat.

================================================

Explanation:

Consider the set {x1,x2,x3,...,xn}. The numbers 1,2,3,...,n represent the index of each x value. So we have n numbers we want to find the average.

The sum of those values is

S = x1+x2+x3+...+xn

When dividing that over n, we get the average A

A = S/n

A = (x1+x2+x3+...+xn)/n

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

Now consider adding 4 to each x value

We have this new set

{x1+4, x2+4,x3+4,...,xn+4}

The new sum T is

T = (x1+4)+(x2+4)+(x3+4)+...+(xn+4)

T = (x1+x2+x3+...+xn) + (4+4+4...+4)

T = S + 4n

Divide both sides by n

T/n = (S+4n)/n

T/n = (S/n) + (4n/n)

T/n = (S/n) + 4

T/n = 47+4

T/n = 51

The new average T/n is 4 larger compared to the old average S/n. So we just add 4 to the old average 47 to get 51 as the new average.

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

If we shift every value the same amount, then the standard deviation and variance will not change. This is because both of those items measure how spread out a distribution is. Shifting each item the same amount, keeps the same spread and shape of the distribution. If only affected some of the items, then the standard deviation and variance would change.

Note that,

variance = (standard deviation)^2

variance = (14)^2

variance = 196

Answer:

x= 1

Step-by-step explanation:

y= -2 + 1

3x - 2y = 5

substituting method:

substituting y= -2+1 in equ. 3x-2y=5

=> 3x - 2(-2 + 1) = 5

=> 3x +4 -2 = 5

=> 3x + 2 = 5

=> 3x = 5 -2

=> 3x = 3

=> x = 3/3

=> x = 1

Answer:

Step-by-step explanation:

1) Order the numbers using the data from 2001-2004

70,60,81,19

2) Add them all together

70+60+81+19= 230

3) Divide the answer you got by the amount of numbers there are

70,60,81,19=4 numbers

230/4 = 57.5

4) Therefore the average rate of change between 2001-2004 is 58 employees (since you can't have a fraction of a person you would have to round)

Answer:

f^-1 (x)= x/18 - 7/54

Step-by-step explanation:

The inverse function of h(x) is x/18 - 7/54

The inverse function is defined as a function obtained by reversing the given function.

Given function h(x) = 18x+7/3

Let g(x) function is the inverse function of h(x)

Suppose y = h(x)

y = 18x+7/3  

y-7/3 = 18x

y/18 - 7/54 = x

g(x) = x/18 - 7/54

Hence g(x) = x/18 - 7/54 is the inverse function of h(x)

The ratio shows how many times one value is contained in another value.

3/2 ≠ 9/8

The ratios are not the same in their simplest form so 3:2 and 9:8 are not equivalent ratios

The ratio shows how many times one value is contained in another value.

Example:

There are 3 apples and 2 oranges in a basket.

The ratio of apples to oranges is 3:2 or 3/2.

We have,

3:2 and 9:8

We will simplify it in its simplest form.

3:2 = 3/2

This is the simplest form.

9:8 = 9/8

This is in its simplest form.

So,

3/2 is not equal with 9/8

If the two ratios are the same we can call them equivalent ratios.

Thus,

3/2 ≠ 9/8

The ratios are not the same in their simplest form so 3:2 and 9:8 are not equivalent ratios.

x=16

Step-by-step explanation:

3 times 16 equals 48 minus 9 equals 39

Answer:

16

Step-by-step explanation:

To solve the equation you must isolate the variable.

3x-9=39

So first, add 9 to both sides

3x-9+9=39+9

3x=48

Then divide both sides by 3

3x/3=48/3
