If y=15 when x=12, find y when x=32

Answers:

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

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:

1/40

Step-by-step explanation:

Multiplication of fractions is just multiplying the numerators and denominators. 1 x 1 = 1

5 x 8= 40

So your answer is 1/40.

1/5 x 1/8 = 1/40

Hope this answer helps you on your math test and good luck.

Answer:

Step-by-step explanation:

If you turn the big one the same way the small one is turned, you will see how hg = zy and how gf = yx

Answer:

69°+72°=141°

180°-141°=39°

x=39°

180°-69°=111°

111°+27°=138°

180°-111°=69°

y=69°

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.

Answer:

The slope is 0

Step-by-step explanation:

Slope can be found using the expression [tex]\frac{y2-y1}{x2-x1}[/tex]

In this case,

y2 = 4

y1 = 4

x2 = 0

x1 = 2

[tex]\frac{4-4}{0-2}[/tex]  = 0/-2 = 0

Answer:

kei = kelvin\_kei(x) evaluates an approximation to the Kelvin function kei x. The function is based on several Chebyshev expansions. For large x, kei x is so small that it cannot be computed without underflow and the function fails.

The correct answer is 26.5ft

The distance between the stick and Lisa is C) 45.6 ft.

The sine rule for triangle ABC is a/sinA = b/sinB = c/sinC.

Given, Lisa and Molly are standing on a bridge and see a tree sticking out of the water.

m∠M = 103°, m∠L = 54°, and the side opposite to ∠L is l which is 22 feet and m is the side opposite to ∠M.

∴ 22/sin54° = m/sin103°.

22/0.8 = m/0.97.

m = 26.67 feet.

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:

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
