X - the score he must earn
The average of n numbers is the sum of these numbers divided by n.

\frac{64+69+73+x}{4}=70 \\&#10;\frac{206+x}{4}=70 \ \ \ \ \ \ \ \ \ \ \ \ |\times 4 \\&#10;206+x=280 \ \ \ \ \ \ \ \ |-206 \\&#10;x=74

He must earn a score of (at least) 74.

Which is a stretch of an exponential decay function? f(x) = one-fifth (one-fifth) superscript x f(x) = one-fifth(5)x f(x) = 5one
vitfil [10]

The exponential function that represents a stretch of a decay function is given as follows:

f(x) = \frac{5}{4}\left(\frac{4}{5}\right)^x

<h3>What is an exponential function?</h3>

An exponential function is modeled by:

y = ab^x.

In which:

  • a is the initial value.
  • b is the rate of change.

It represents a stretch if a > 1, and a decay function if b < 1. Researching the problem on the internet, the correct option is given as follows:

f(x) = \frac{5}{4}\left(\frac{4}{5}\right)^x

12345 [234]

Answer:

Kofi spent the most money.

Step-by-step explanation:

We have been given that Kofi and Ella each have the same amount of money to spend on food shopping. Kofi spends 3/4 of his money and Ella spends 63% of her money.

Let us convert 3/4 into percent.

\text{3/4 as a percent}=\frac{3}{4}\times 100\%

\text{3/4 as a percent}=0.75\times 100\%

\text{3/4 as a percent}=75\%  

We can see that \frac{3}{4} is equal to 75%.

Since both have the same amount of money, so 75% will be greater than 63% of same amount. Therefore, Kofi spent the most money.
