Answer: B and D or 2 and 4

Step-by-step explanation:

1. is NOT correct as the mean absolute deviation is 22 not 15

2. is CORRECT the mean absolute deviation is 18

the mean of A is 216

the mean of B is 215

one tenth of 215/216 is 21.5/21.6 that is about the absolute mean deviation which 18/22

Which makes one tenth the wrong answer.

This is also makes one twentieth the correct answer

Write the exponential function.
sertanlavr [38]

Answer:

f(x) = 10*(b)^x

Step-by-step explanation:

exponential function : y=a*(b)^x

where a = y intercept and b = factor ( what you multiply by )

looking at the table the y intercept is at (0,10) so a = 10

so we now have y = 10 * (b)^x

to find the factor we simply plug in one of the ordered pairs.

note that the ordered pair chosen does not effect the outcome

i chose (2,250)

we have y = 10 * (b)^x

(x,y) = (2,250)

250 = 10 * (b)^2

divide both sides by 10

25 = b^2

take the square root of both sides

5 = b

the final equation would be f(x) = 10 * (b)^x
