Mr. Jones has to invest in three types of stocks, low-risk, medium-risk, and high-risk. He invests according to three principles. The amount invested in low-risk stocks will be at most more than the amount invested in medium-risk stocks. At least will be invested in low- and medium-risk stocks. No more than will be invested in medium- and high-risk stocks. The expected yields are % for low-risk stocks, % for medium-risk stocks, and % for high-risk stocks. How much money should Mr. Jones invest in each type of stock to maximize his total expected yield?
Answers
Answer:
Since the numbers are missing, I looked for a similar question:
Mr. Jones has $9000 to invest in three types of stocks: low-risk, medium-risk and high-risk. He invests according to the following rules: the amount invested in low-risk stocks will be at most $1000 more than the amount invested in medium-risk stocks. At least $7000 will be invested in a combination of low- and medium-risk stocks. No more than $7000 will be invested in a combination of medium- and high-risk stocks. The expected annual returns are 6% for low-risk stocks, 7% for medium-risk stocks, and 8% for high-risk stocks. How much should he invest in each type of stock to maximize his total expected yield?
let:
L = low risk stocks
M = medium risk stocks
H = high risk stocks
maximize 0.06L + 0.07M + 0.08H
L + M + H ≤ 9000
L ≥ M + 1000
L + M ≥ 7000
M + H ≤ 7000
using solver, the optimal solution = 4,000L + 3,000M + 2,000H , which yields a maximum profit = $610
Mr. Jones should invest $4,000 in low risk stocks, $3,000 in medium risk stocks and $2,000 in high risk stocks.

To convert a Unit Rate into another, we have to add or subtract a Unit Ratio to the original Unit Rate.
To convert a Unit Rate into another, we have to multiply the original Unit Rate by one or two Unit Ratios.
To convert a Unit Rate into another, we have to obtain a denominator different than one.
It is no possible to convert a Unit Rate into another.
Answers
Answer: To convert a Unit Rate into another, we have to multiply the original Unit Rate by one or two Unit Ratios.
Step-by-step explanation:
Unit rates are usually convertible to other units using multiplication and division attributes to ensure equivalence depending on preference or units being converted. Once the ratio or proportion between the two units (original and target) have been obtained, the original Unit is multiplied by the ratio of the two units to obtain the target unit rate. This way both units are equivalent to each other.
the histogram to the right displays the height of 122 trees and Mr. Maciag's subdivision. He is very excited about autumn and the leaves changing colors. Height ranged between 108 cm and 345 cm.

Answer: 50
Step-by-step explanation:

Is asking, "What is the frequency (number of trees) that have a height of 250"
Look at the graph to see that when x = 250 (height), y = 50 (trees).

Find the error and and the correct answer
Answers
Answer:
Error: Multiplied both sides by 3/4 instead of 4/3.
Solution: x = 16
Step-by-step explanation:
The error is that you multiplied both sides by [tex]\frac{3}{4}[/tex] instead of dividing both sides by [tex]\frac{3}{4}[/tex].
This is an error because:
[tex]\frac{3}{4} *\frac{3}{4} x\neq x[/tex]
Actually:
[tex]\frac{3}{4} *\frac{3}{4} x=\frac{9}{16} x[/tex]
What you want to do instead is divide both sides by [tex]\frac{3}{4}[/tex]. Remember, dividing both sides by [tex]\frac{3}{4}[/tex] would be the same as multiplying both sides by [tex]\frac{4}{3}[/tex].
Now, lets find the correct answer:
[tex]\frac{3}{4}x=12[/tex]
Multiply both sides by 4/3.
x = 16
So the correct answer would be x = 16.

Andrew purchased some drinks and some chips. Each bag of chips cost $2.00 and
each drink cost $2.50. The expression 2x + 2.5y gives the total amount of money
spent by Andrew on chips and drinks. What is the meaning of the term 2.5y?
Answers
Answer:
2.5y=amount spent on drinks
Step-by-step explanation:
If chips are $2 and drinks are $2.50 and we do not know how many he bought of each, we put this into an equation which is
2x+2.5y
x=number of bags of chips while the 2 is two dollars per bag
so, if he bought 2 bags of chips 2(2)= $4 spent.
y= number of drinks and 2.5 is $2.5 per drink, so if he bought 4 drinks:
2.5(4)= $10 spent on drinks.

The Johnson family income is
estimated to be $125,000 per year. Mary wanted to write this number
in scientific notation. If she wrote
1.25 x 10" , what value of n should
she use?
Answers
Answer:
The value of n would be 5
Step-by-step explanation:
This is understanding how to take numbers and writing them in scientific notation.
125,000 = 1.25 x 10⁵
First of all.
125,000 = 125,000.0 (See that decimal point?)
We want that decimal point behind the number 1 as seen in the scientific notation. All you have to do is move that decimal point to the left until you reach the ones place.
125000. → 1.25
(You're not finished yet)
Since we moved the decimal five times, then we must put an exponential value of 5 above the 10
In conclusion:
125,000 = 1.25 x 10⁵

A dog trainer is trying to find a triangular area behind his house that encloses 1800 square feet for his dog to run. He has the first two fence posts at (6, 0) and at (0, 25). The final fence post is on the property line at x = 30. Find the point where the trainer can place the final fence post.
Answers
Answer:
[tex]C = (30,500)[/tex]
Step-by-step explanation:
Given
[tex]Area = 1800ft^2[/tex]
[tex]A = (6,0)[/tex]
[tex]B = (0,25)[/tex]
[tex]C(x,y) = (30,y)[/tex]
Required
Determine the coordinates of C
The area of triangle is calculated as thus:
[tex]Area = \frac{|A_x(B_y - C_y) + B_x(C_y - A_y) + C_x(A_y - B_y)|}{2}[/tex]
This gives:
[tex]1800= \frac{|6(25 - y) + 0(y - 0) + 30(0 - 25)|}{2}[/tex]
[tex]1800= \frac{|6(25 - y) + 30(0- 25)|}{2}[/tex]
[tex]1800= \frac{|6(25 - y) + 30(-25)|}{2}[/tex]
[tex]1800= \frac{|150 - 6y -750 |}{2}[/tex]
[tex]1800= \frac{|150 -750- 6y |}{2}[/tex]
[tex]1800= \frac{|-600- 6y |}{2}[/tex]
Multiply through by 2
[tex]2 * 1800= |-600- 6y|[/tex]
[tex]3600= |-600- 6y|[/tex]
[tex]3600= |-(600+ 6y)|[/tex]
[tex]3600= 600+ 6y[/tex]
Solve for 6y
[tex]6y = 3600 - 600[/tex]
[tex]6y = 3000[/tex]
Solve for y
[tex]y = 3000/6[/tex]
[tex]y = 500[/tex]
Hence:
The point is:
[tex]C = (30,500)[/tex]

A rectangular athletic field is twice as long as it is wide. If the perimeter of the athletic field is yards, what are its dimensions 76
Answers
Answer:
The length is 25.3 yards, while the width is 12.7 yards.
Step-by-step explanation:
Perimeter of a rectangle, P = 2(l + w)
where l is its length and w the width.
Given that:
perimeter = 76 yards
It is twice as long as its wide, length = 2w
width = w
Then,
P = 2(l + w)
76 = 2(2w + w)
divide through by 2, to have;
38 = 2w + w
38 = 3w
⇒ w = 12.67 yards
Thus,
length = 2w = 2 x 12.67 = 25.34 yards
The length is 25.3 yards, while the width is 12.7 yards.

Mabel earn 180$ in 18 hours.at this rate how many dollars will she earn in 30 hours?
Answers
Since she earns $180 in 18 hours, she earns a rate of $ 180/18 per hour, which is $10 per hour.
In 30 hours she earns 30 times 10 dollars, which is 300 dollars.
You could also set up a proportion saying that 180/18 = x/30, then cross multiply to get 18x = 5400, and divide by 18 on both sides to get 300.
Answer:
Mabel will earn 300$ in 30 hours
Step-by-step explanation:
I took 180 and divided it by 18 so that I can find how much money she earns per hour.
180÷18= 10
10 × 30= 300

IQ scores have a mean of 100 and a standard deviation of 15. Kate has an IQ of 121. (a) What is the difference between Kate's IQ and the mean
Answers
Answer:
(a) The difference between Kate's IQ and the mean is 21
(b) The z score is 1.4
Step-by-step explanation:
Here is the complete question:
IQ scores have a mean of 100 and a standard deviation of 15. Kate has an IQ of 121. (a) What is the difference between Kate's IQ and the mean (b) Convert Kate's IQ score to a z score.
Step-by-step explanation:
(a) To determine the difference between Kate's IQ and the mean, this can be done by subtracting the mean from Kate's IQ.
Mean = 100
Kate's IQ = 121
Difference between Kate's IQ and the mean = 121 - 100 = 21
Hence, the difference between Kate's IQ and the mean is 21.
(b) To convert Kate's IQ score to a z score,
z score is given by the formula
[tex]z =\frac{x - \mu}{\sigma}[/tex]
Where [tex]x[/tex] is the score
[tex]\mu[/tex] is the mean
and [tex]\sigma[/tex] is the standard deviation
From the question,
[tex]x[/tex] = 121
[tex]\mu[/tex] = 100
[tex]\sigma[/tex] = 15
Then, the z score is
[tex]z =\frac{x - \mu}{\sigma}[/tex]
[tex]z =\frac{121 - 100}{15}[/tex]
[tex]z =\frac{21}{15}[/tex]
[tex]z =\frac{7}{5}[/tex]
z = 1.4
Hence, the z score is 1.4.
