The correct answer would be A. The correct relationship when the variation of the input and output is inverse would be Output=Constant/Input. We can see that as input increase, the output would increase accordingly. The variation would be the same when one variable is decreased.

Find the z-score such as 88% of the area under the normal curve is to the left of the z-score
jok3333 [9.3K]
If you have a calculator with statistical functions, that's the way to go.

On my TI-83, I typed in  invNorm(0.88) and got the result z = 1.17.

88% of the area under the normal curve is to the left of z = 1.17.

I need algebra help.....
Lubov Fominskaja [6]

Answer:

y=4(3)^x

Step-by-step explanation:

From the table given in the question,

x            y              Difference                  Ratio

1            12                     -                             -

2           36              36-12 = 24              \frac{36}{12}=3

3          108            108-36 = 72             \frac{108}{36}=3

4          324            324-108 = 216        \frac{324}{108}=3

5          972            972-324 = 648      \frac{648}{216}=3

There is a common ratio of 3 in each successive term.

Therefore, data given in the table will represent an exponential function.

y=a(b)^x

For a point (1, 12),

12=a(b)^1

ab=12 ------(1)

For another point of the table (2,36),

36=a(b)^2

ab^2=36 --------(2)

Equation (2) divided by equation (1)

\frac{ab^2}{ab}=\frac{36}{12}

b=3

From equation (1),

3a=12

a=4

Therefore, exponential function will be,

y=4(3)^x
