Answer:

f(x)=120+15x

Step-by-step explanation:

Given : Emerson has $120

             Each week, he saves an additional $15.

To Find: Write a function f(x) that models the total amount of money Emerson has after x weeks.

Solution:

He saves in 1 week = $15

He saves in x weeks = $15x

He already has $120

So, total amount of money = 120+12x

So, Function: f(x)=120+15x

Hence  a function f(x) that models the total amount of money Emerson has after x weeks is f(x)=120+15x .

Which set of ordered pairs could be generated by an exponential function ?
lawyer [7]

Answer:

The third choice is the correct answer

Step-by-step explanation:

The set of ordered pairs which could be generated by an exponential function is

(1,\frac{1}{2}),(2,\frac{1}{4}),(3,\frac{1}{8}),(4,\frac{1}{16})

If we examine the y-values of this set of ordered pairs, we can see that they have a common ratio of

r=\frac{1}{4}\div \frac{1}{2}

r=\frac{1}{4}\times 2

r=\frac{1}{2}

This makes it exponential.

Contact [7]

Answer:  a. n= 1068

b. n= 164

Step-by-step explanation:

The formula to find the sample size :

n=p(1-p)(\dfrac{z^{*}}{E})^2

, where p=prior population proportion , z* = critical z-value and E = Margin of error.

Here , let p=proportion of computers that use a new operating system.

Given : Confidence level = 95%

i.e. z* = 1.96  [by z-table]

Margin of error : E = 3% =0.03

a. If p is unknown , then we assume p=0.5

Then, n=(0.5)(1-0.5)(\dfrac{1.96}{0.03})^2=1067.11111\approx1068

i.e. n= 1068

b. p=0.96

Then, n=(0.96)(1-0.96)(\dfrac{1.96}{0.03})^2=163.908266667\approx164

i.e. n= 164.
