It is 14% as you add up all of the numbers and divide 10 by that number and finally multiply by 100 for a percent

Answer:

A-14%

Step-by-step explanation:

We are given a table as

Color                Red   Blue   Green   Purple

Frequency        10      16      28          18

Relative frequency is calculated as

           \dfrac{frequency}{sum of frequencies}\times 100

Hence, relative frequency for red=

      \dfrac{10}{10+16+28+18}\times 100

=     \dfrac{10}{72}\times 100

=   13.88%

≈  14%

Hence, the correct option is:

A- 14%

Which situation could be represented by an exponential function select each correct answer
ANTONII [103]

Answer:

The first and third options are the examples of exponential functions.

Step-by-step explanation:

When a quantity is compounded after a certain interval of time at a certain rate, then we can assume that the situation can be represented by an exponential function.

In the first option:  An event organizer finds each year's attendance for the past five years is about \frac{4}{5} of previous year's attendance.

So, here the total attendance is compounding every year by a factor \frac{4}{5} of previous year's attendance.

Again, in the third case: The total population is increasing by about 7.5% each year.

Hence, the population is compounded every year by 7.5% of the previous year's population.

Therefore, the first and third options are examples of exponential functions. (Answer)

Please help which should I choose
Aleksandr [31]
<h3>Answer: Choice A. Graph (1)</h3>

Reasoning:

If it is at all possible to draw a single vertical line through more than one point on the curve, then the graph is not a function. With graphs (2), (3) and (4), we can draw a vertical line through more than one point on those curves, so they aren't functions. Graph (1) is the only thing left. This graph is a function because it is not possible to draw a single vertical line through more than one point. It passes the vertical line test. Any input (x) leads to exactly one and only one y output.

Nice work on getting the correct answer when you chose "graph (1)".
