The administrator of a $200,000 trust fund must adhere to following guidelines.

a. The money may be invested in three different types of securities: a utilities stock paying a 9% dividend, an electronics stock paying a 4% dividend, and a bond paying 5% interest.
b. The amount invested in the stocks cannot be more than half the total amount invested; the amount invested in the utilities stock cannot exceed $40,000; and the amount invested in the bond must be at least $70,000.
c. The total amount need not be fully invested at any one time.

Required:
Setup an LP problem to maximize profit.

Answers

Answer 1

Step-by-step explanation:

let us give all the quantities in the problem variable names.

x= amount in utility stock  

y = amount in electronics stock  

c = amount in bond

“The total amount of $200,000 need not be fully invested at any one time.”

becomes

x + y + c ≤ 200, 000,

Also

“The amount invested in the stocks cannot be more than half the total amount invested”

a + b ≤1/2 (total amount invested),

=1/2(x + y + c).

(x+y-c)/2≤0

“The amount invested in the utility stock cannot exceed $40,000”

a ≤ 40, 000

“The amount invested in the bond must be at least $70,000”

 c ≥ 70, 000

Putting this all together, our linear optimization problem is:

Maximize z = 1.09x + 1.04y + 1.05c

subject to

x+ y+ c ≤ 200, 000

x/2 +y/2 -c/2 ≤ 0

              ≤ 40, 000,

              c ≥ 70, 000

a ≥ 0, b ≥ 0, c ≥ 0.

Ruchi had 2 1/2 litres of milk. She used 1/2 litre for curd, 3/5 litre for tea, 1/4 litre for coffee, and the remaining she gave to her children in the breakfast. How much milk was used by the children for breakfast?

Answers

Answer: 1 15/100

Step-by-step explanation: 2 1/2- 1/2 = 2 - 3/4 = 1 3/4 - 3/5 = 1 15/100

Given parameters:

Total volume of milk Ruchi has  = [tex]2\frac{1}{2}[/tex] liters

Amount used for curd  = [tex]\frac{1}{2}[/tex] liters

Amount used for tea = [tex]\frac{3}{5}[/tex] liters

Amount used for coffee  = [tex]\frac{1}{4}[/tex] liters

Unknown:

Quantity of milk used by the children for break fast = ?

Since this quantity is the remaining volume;

Remaining volume  = Total volume - (Amount used for curd + amount used for tea + amount used for coffee)

  Remaining volume = [tex]\frac{5}{2} - (\frac{1}{2} + \frac{3}{5} + \frac{1}{4} )[/tex]

 Remaining volume = [tex]\frac{23}{20}[/tex]

The remaining volume used by the children is [tex]\frac{23}{20}[/tex]

Answer:

y = x^2 +x +1; (-1/2, 3/4)y = 3x^2 -15x +12; (-2, 54), (5, 12)y = -1/2x^2 +2x +5; (0, 5)

Step-by-step explanation:

1. The graph looks like the vertex is at x = -1/2. So we can start with the equation y = (x +1/2)^2 +k. At x=0, this becomes 1 = 1/4 +k, or k = 3/4. The leading coefficient of 1 is consistent with the other points shown, so the equation is ...

  y = (x +1/2)^2 +3/4 . . . . vertex is (-1/2, 3/4)

  y = x^2 +x +1

__

2. The zeros appear to be at x=1 and x=4, so the factored form of the equation is ...

  y = a(x -1)(x -4)

At x = 0, this is ...

  12 = a(-1)(-4)

  3 = a

So, the equation is ...

  y = 3x^2 -15x +12

The values at the two points of interest are ...

  y = 3(-2-1)(-2-4) = 54 . . . . point (-2, 54)

  y = 3(5 -1)(5 -4) = 12 . . . . point (5, 12)

__

3. Using the vertex shown, the vertex form of the equation is ...

  y = a(x -2)^2 +7

Filling in the point (-2, -1), we can find the value of a:

  -1 = a(-2-2)^2 +7

  -8 = 16a

  a = -8/16 = -1/2

So, the equation is ...

  y = -1/2x^2 +2x +5

For x=0, the y-value is 5. The y-intercept is (0, 5).

Answer:

9514 1404 393

y = x^2 +x +1; (-1/2, 3/4)

y = 3x^2 -15x +12; (-2, 54), (5, 12)

1. The graph looks like the vertex is at x = -1/2. So we can start with the equation y = (x +1/2)^2 +k. At x=0, this becomes 1 = 1/4 +k, or k = 3/4. The leading coefficient of 1 is consistent with the other points shown, so the equation is ...

PLEASE HELP FAST!

Answers

Answer:

The area of the shaded part is 100 [tex]cm^2[/tex]

Step-by-step explanation:

Subtracting Areas:

We can find the shaded area by adding or subtracting areas.

We'll use the latter method.

The total shape is a rectangle of side lengths 15 cm and 10 cm. Thus its area is:

[tex]A_t=15\ cm\cdot 10\ cm=150\ cm^2[/tex]

The area of each non-shaded square is:

[tex]A_s=(5\ cm)^2=25\ cm^2[/tex]

The total non-shaded area is

[tex]2*A_s=50\ cm^2[/tex]

Thus, the shaded area is:[tex]A_{shaded}=A_t-2*A_s=150 - 50 = 100[/tex]

The area of the shaded part is 100 [tex]cm^2[/tex]

PLEASE HELP ME PLS!

Answers

Answer:10

Step-by-step explanation:

I guessed

The area of the rectangle is 200 square cm

The radius of the circle is given as:

[tex]r = 5cm[/tex]

The width of the rectangle is made by 2 circles (i.e. 4 radii).

So, we have:

[tex]Width = 4r[/tex]

The length of the rectangle is made by 1 circle (i.e. 2 radii).

So, we have:

[tex]Length = 4r[/tex]

The area of the rectangle is then calculated as:

[tex]Area =Length * Width[/tex]

This gives

[tex]Area = 2r * 4r[/tex]

[tex]Area = 8r^2[/tex]

Substitute 5 for r

[tex]Area = 8 * 5^2[/tex]

[tex]Area = 200[/tex]

Hence, the area of the rectangle is 200 square cm

Write an equation of the line in slope-intercept form.

Answers

Answer:

The answer would be y=-1/3x+1.

Step-by-step explanation:

To find the slope, you must use the formula y2-y1/x2-x1. That would make it 1-2/0-(-3) which the slope is -1/3. Now, using the formula y-y1=m(x-x1) which would be y-2=-1/3(x-(-3) if you plug it in. Solving the equation, you would get y=-1/3x+1.

Suppose you conduct a hypothesis test about a population mean when the standard deviation is unknown by calculating a t statistic and determining whether to reject the null hypothesis. Assume that your t statistic is a positive value and that you will reject the null hypothesis when t is very large. For each of the potential changes to the components of your study design or the results listed below, determine the change to the t statistic.

a. A switch from using a two-tailed test to a one-tailed test
b. An increase in the sample variance (s^2)
c. An increase In the significance level (such as using α= 0.05 instead of σ= 0.02)
d. A decrease in the sample Size (n)

Answers

Answer:

a. remain the same

b. decrease

c. remain the same

d. t decreases

the answers are in bold letters under each question. Thank you

Step-by-step explanation:

a. A switch from using a two-tailed test to a one-tailed test

A switch from 2 tailed test to one tailed test will have t statistic remain the same. This does not change the value of t statistic

b. An increase in the sample variance (s^2)

when sample variance s^2 is increased, we will have it that standard error has increased. therefore t statistic will decrease

c. An increase In the significance level (such as using α= 0.05 instead of σ= 0.02)

t statistics will remain the same. this is due to the fact that significance level is not a part of the t statistics formula.

d. A decrease in the sample Size (n)

when sample size is decreased, standard error will increase. therefore t statistic will decrease.

The use of student-test implies:

Normal distributionSample size below n < 30

The solution is:

a) t(s) will be the same

b) t(s) will decrease

c) t(s) will be the same

d) t(s) will decrease

a) To calculate t(s), we use the equation:

t(s) = (μ  -  μ₀)/s/√n         (1)

where:

μ is sample mean

μ₀ is the population mean

s is sample standard deviation

n sample size

As  we can see, t(s) does not depend on the confidence level (α), therefore changing confidence level,  would not affect t(s) value

b) Increasing s²,  will make t(s) decrease as from equation (1)

c) As explained in letter a), t(s) does not depend on α. Hence, changing α, would not affect the value of t(s)

d) If the sample size n  decrease t(s) will decrease

George could have used the expression (0.10)(6)(0.10)(60) to determine 30% of 60.

(0.10) represents 10% or 0.10 as a decimal. Since 30% is three times 10%, George can use three instances of (0.10) to represent 30%.

(6) represents the value 6, which is the number being multiplied by the percentage.

(0.10)(60) represents 10% of 60, which is 6.

Multiplying (0.10)(6)(0.10)(60) gives us the result of 6, which is 30% of 60.

Therefore, George could have used the expression (0.10)(6)(0.10)(60) to calculate 30% of 60.
