This table shows the input and output values for an exponential function f(x) . what is the ratio of outputs for any two inputs that are one value apart? −2 −12 4 2 x −3 −2 −1 0 1 2 3 f(x) −18 −14 −12 −1 −2 −4 −8

Step-by-step explanation:

1) Rewriting the table below:

(Check the graph below)

2) Inputs( x-values) and the outputs are dependent variables (y).

Picking two points

3) Similarly to a Geometric Sequence. Looking to the f(x) row to find the ratio, we need always to divide the later term over the previous one:

4) Hence,

i do not know the answer

step-by-step explanation:

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
