Naddik [55]

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

$\frac{64+69+73+x}{4}=70 \\
\frac{206+x}{4}=70 \ \ \ \ \ \ \ \ \ \ \ \ |\times 4 \\
206+x=280 \ \ \ \ \ \ \ \ |-206 \\
x=74$

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:

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

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

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.
