The return received after 30 months on an investment of $6000 will be $1800.
According to the question,
We have the following information:
You invest $6000 in a restaurant. The investment has a return of 12% per year.
We know that the following formula is used to find the simple interest on the amount:
Simple interest = principal*rate*time/100
Now, we have the following values in this case which we will put in the formula:
Principal = $6000
Rate = 12%
Time = 2.5 years
Simple interest = (6000*12*2.5)/100
Simple interest = $1800
Hence, the amount received after 30 months on an investment of $6000 will be $1800.

b. How much will you save in a year if you replace the bulb with an LED bulb that provides the same amount of light
using only 15 watts of power?
a. The daily cost of keeping lit a 60-watt light bulb for 10 hours each day is $
(Round to three decimal places as needed.)
b. The yearly savings of replacing the 60-watt light bulb with a 15-watt light bulb is $
(Round to two decimal places as needed.)
Answer: a) $78 per day
b) $21,352.50
Step-by-step explanation:
a) 60x10=600
600x0.13= $78 per day
b) 15x10=150
150x0.13=$19.50 per day
19.50x365= $7,117.50 per year (with a 15watts lightbulb)
$78x365=$28,470 per year (with a 60watts lightbulb)
$28,470-7,117.50= $21,352.50
The area of the right triangle shown is 24 square feet. Which equations can be used to find the lengths of the legs of the triangle? Select three options. 0.5(x)(x + 2) = 24 x(x + 2) = 24 x2 + 2x – 24 = 0 x2 + 2x – 48 = 0 x2 + (x + 2)2 = 100
The equation that is used to find the length of the legs of the triangle is
0.5(x)(x + 2) = 24 , x² + (x + 2)² = 100 and x² + 2x – 48 = 0
The area of the triangle is 24 square feet.
We know that the area of a triangle is given by the formula
1/2 × base × height.
Now in the attached figure we can see that the length of the base is x feet
The height of the right-angled triangle is (x+2) feet.
So the area of the triangle will be:
area = 1/2 · (x) · (x+2)
or, area = 0.5x(x+2)
But the area of the triangle is 24 square feet. Therefore the Equation to find the legs will be 0.5x(x+2) = 24.
Now if we use the properties of Pythagoras theorem we can write the formula as
hypotenuse² = sum of squares of legs
10² = x² + (x+2)²
Therefore we get the second equation.
Now simplifying the above equation we get:
10² = x² + (x+2)²
or, 2x² + 4x - 96 = 0
or, x² + 2x - 48 = 0
This is the third option.
Therefore the required equation are:
0.5(x)(x + 2) = 24 , x² + (x + 2)² = 100 and x² + 2x – 48 = 0 .

An orange juice producer buys oranges from a large orange grove that has one variety of orange. The amount of juice squeezed from these oranges is approximately normally distributed, with a mean of 4.10 ounces and a standard deviation of 0.20 ounce. Suppose that you select a sample of 16 oranges.
a. What is the probability that the sample mean amount of juice will be at least 4.03ounces?
b. The probability is 74% that the sample mean amount of juice will be contained between what two values symmetrically distributed around the population mean?
c. The probability is 78% that the sample mean amount of juice will be greater than what value?
The measures, using the normal distribution and the central limit theorem, are given as follows:
a) Probability of at least 4.03 ounces: 0.9192 = 91.92%.
b) Probability of 74% that it is between 4.04 ounces and 4.16 ounces.
c) Probability of 78% that it is greater than 4.06 ounces.
Normal Probability DistributionThe z-score of a measure X of a variable that has mean symbolized by [tex]\mu[/tex] and standard deviation symbolized by [tex]\sigma[/tex] is obtained by the rule presented as follows:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score represents how many standard deviations the measure X is above or below the mean of the distribution, depending if the obtained z-score is positive or negative.Using the z-score table, the p-value associated with the calculated z-score is found, and it represents the percentile of the measure X in the distribution.The parameters regarding the amount of juice squeezed from these oranges are given as follows:
[tex]\mu = 4.10, \sigma = 0.2, n = 16, s = \frac{0.2}{\sqrt{16}} = 0.05/tex]
The probability that the sample mean amount of juice will be at least 4.03 ounces is one subtracted by the p-value of Z when X = 4.03, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
Z = (4.03 - 4.10)/0.05
Z = -1.4.
Z = -1.4 has a p-value of 0.0808.
1 - 0.0808 = 0.9192.
Considering the symmetry of the normal distribution, the middle 74% of the measures is bounded by:
The 13th percentile, which is X when Z = -1.125.The 87th percentile, which is X when Z = 1.125.Hence the lower bound is:
[tex]Z = \frac{X - \mu}{s}[/tex]
-1.125 = (X - 4.10)/0.05
X - 4.10 = -1.125 x 0.05
X = 4.04.
The upper bound is:
[tex]Z = \frac{X - \mu}{s}[/tex]
1.125 = (X - 4.10)/0.05
X - 4.10 = 1.125 x 0.05
X = 4.16.
The probability is 78% that the sample mean amount of juice will be greater than the 22th percentile, which is X when Z = -0.77, hence:
[tex]Z = \frac{X - \mu}{s}[/tex]
-0.77 = (X - 4.10)/0.05
X - 4.10 = -0.77 x 0.05
X = 4.06 ounces.

How to find a trend line for the data?In order to determine a linear equation of the trend line (line of best fit) that models the data points contained in the table, we would have to use a scatter plot.
In this scenario, the number of games would be plotted on the x-axis of the scatter plot while the profit (in dollars) would be plotted on the y-axis of the scatter plot.
On the Excel worksheet, you should right click on any data point on the scatter plot, select format trend line, and then tick the box to display an equation for the trend line on the scatter plot.
From the scatter plot (see attachment) which models the relationship between the data points in the table, a linear equation of the trend line is given by:

A cherry muffin costs 350 shillings
A blueberry muffin costs 210 shillings
An apple costs 140 shillings

How to determine the cost of eachThe information given in the question is interpreted as below
A cherry muffin = 350 shillings
A blueberry muffin = 3 * damson ones
An apple + a blueberry muffin = 1 cherry muffin
A cherry muffin + 2 damson ones = 2 apple + 1 blueberry
from: 1 blueberry muffin, B = 3 * damson ones, D
D = B / 3
Also, An apple, A + B = 1 cherry muffin, C
A = C - B
C + 2D = 2A + B
substituting the values
350 + 2 * (B/3) = 2 * (350 - B) + B
350 + 2B/3 = 700 - 2B + B
collecting like terms
2B/3 + B = 700 - 350
5B/3 = 350
5B = 1050
B = 1050/5
B = 210
