Answer:

P = number of adults who have shopped at least once on the internet / number sampled adults

Step-by-step explanation:

Step 1

Let X be the number sampled adults

Let Y be the number of adults who have shopped at least once on the internet.

Let P be the probability that a randomly selected adult has shopped on the Internet.

Step 2

P = number of adults who have shopped at least once on the internet / number sampled adults

P = Y/X

An example:

If X is 1000 adults and Y is 200 adults therefore P = 200/1000 = 0.2

One can therefore infer that approximately 0.2 of the population surfs the internet at least once in a week.

Okay, my prior answer got deleted for no work, apparently.
I'll re-post it though.

That word problem translates to:
8n -4=0 \\ +4 \\  \\ 8n=4 \\ /8 \\  \\ n=1/2

On a trip, you had to change your money from dollars to euros. You got 450 euros for 600 dollars. Which is a unit rate that desc
chubhunter [2.5K]
The number of Euros received against 600 dollars = 450
Then
For 1 dollar, the number of euros = (450/600) euros
                                                       = (45/60) euros
                                                       = ( 3/4) euros
                                                       = 0.75 euros
So the unit rate that describes the exchange rate is 0.75 euros per dollar. So the correct option among all the options given in the question is option "A". I hope the procedure for getting to the correct result is clear enough for you to understand. In future you can use this procedure for solving similar problems.

A researcher determines that the number of bacteria increase at a rate modeled by =25*2^x. What is the growth rate?
dolphi86 [110]

Answer:

100%

Step-by-step explanation:

An exponential equation with a growth rate can be expressed as: f(x)=A(1+r)^x where r is a positive number, and represents the growth rate.

In this case since the base of the exponent equals 2, that means r=1, since 1+1=2. This means it has a growth rate of 100%, which makes sense, since the base is 2, meaning it doubles or increases by 100% every time x increases by 1.
