A coffee business sells a pound of coffee for $ 9.75. Monthly expenses are $ 4,500 plus $ 4.25 for every pound of coffee sold. a

hram777 [196]

Answer:

a. IT = 9.75 * X

b. GT = 4500 + 4.25 * X

c. G = 9.75 * X - 4500 - 4.25 * X

Step-by-step explanation:

With the data of the statement we can get a function. Let X be the number of pounds sold.

to. Monthly income

IT = 9.75 * X

b. Monthly expenses

GT = 4500 + 4.25 * X

c. Monthly Earnings (Monthly Income - Monthly Expenses)

G = 9.75 * X - (4500 + 4.25 * X)

G = 9.75 * X - 4500 - 4.25 * X

18. A set of data has a sample mean of 65.4 and a standard deviation of 1.2. If the sample size is 45, what is the 99% confidenc

Agata [3.3K]

Given:

Sample mean = 65.4

Standard deviation = 1.2

Sample size = 45

Confidence level = 99%

To find:

The confidence interval.

Solution:

The formula for confidence interval is

$CI=\overline{x}\pm z^*\dfrac{s}{\sqrt{n}}$

where, $\overline{x}$ is sample mean, z* is confidence value, s is standard deviation and n is sample size.

Confidence value or z-value at 99% = 2.58

Putting the given in the above formula, we get

$CI=65.4\pm 2.58\times \dfrac{1.2}{\sqrt{45}}$

$CI=65.4\pm 0.46$

$CI=65.4-0.46\text{ and }CI=65.4+0.46$

$CI=64.94\text{ and }65.86$

Therefore, the correct option is D.

If Leo is 6 years old and Max is 12 years older, in how many years wil Max be 3 times older than Leo?

Sergio039 [100]

Answer:

in 36 years

Step-by-step explanation:

in 36 years, Max will be 54 YEARS OLD and Leo will be 18 YEARS OLD.

54÷18= 3

this means that when max is 54, he will be 3 times older than leo

it can also be when Leo is 6 and Max is 18 because:

18÷6=3 means max is already 3 times older than leo

What is the unit rate for the proportional relationship represented by the equation y=4/5x

slava [35]

Answer:

<em>the unit rate is 0.8x per unit y</em>

<em></em>

Step-by-step explanation:

the proportional relationship is y = $\frac{4x}{5}$

this means that the constant of proportionality k = $\frac{4}{5}$ = 0.8

re-writing, we have

<em>y = 0.8x</em>

<em>therefore, the unit rate is 0.8x per unit y</em>
