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.

A superstar major league baseball player just signed a new deal that pays him a record amount of money. The star has driven in an average of 110 runs over the course of his career, with a standard deviation of 31 runs. An average player at his position drives in 80 runs. What is the probability the superstar bats in fewer runs than an average player next year

Answers

Answer:

0.1667

Step-by-step explanation:

Given that:

Average / mean runs (m) = 110 runs

Standard deviation (σ) = 31 runs

Number of runs driven in by an average player in his position = 80

The probability the superstar bats in fewer runs than an average player next year will be the :

P(x < 80)

Zscore = (x - mean) / σ

Zscore = (80 - 110) / 31

Zscore = - 30 / 31

Zscore = - 0.9677419

P(Z < 0.9677419) = 0.1666 ( from z probability calculator)

= 0.1667

Answers

Answer:

The slope of the line given by the linear equation is -2

The slope of the line shown in the graph is -1

Step-by-step explanation:

The line equation, y = -2x + 7 is written in the slope-intercept form, which is represented by the formula, y = mx + b.

m is the slope, while b is the y-intercept.

Therefore, the slope of the line of the linear equation, y = -2x + 7 is -2.

Find the slope of the line shown in the graph using the formula, [tex] m = \frac{y_2 - y_1}{x_2 - x_1} [/tex].

Use the coordinates of any two points on the line. Let's use (0, 5) and (5, 0)

Let,

[tex] (0, 5) = (x_1, y_1) [/tex]

[tex] (5, 0) = (x_2, y_2) [/tex]

[tex] m = \frac{0 - 5}{5 - 0} = \frac{-5}{5} = -1 [/tex]

Therefore:

The slope of the line given by the linear equation is -2

The slope of the line shown in the graph is -1

The life zones on Mount Rainier, a mountain in Washington, can be approximately classified by elevation, as follows.

Low-elevation forest: above 1700 feet to 2500 feet
Mid-elevation forest: above 2500 feet to 4000 feet
Subalpine: above 4000 feet to 6500 feet
Alpine: above 6500 feet to the summit


Write a compound inequality that represents the elevation range h
for each type of plant life.

Answers

Answer:

Look down below

Step-by-step explanation:

It's been a little while since I've looked at compound inequalities, so forgive me if this is a bit long.

Let's start with the Low Elevation Forest. Let x represent what is considered the forest. If this is above 1700, x>1700 (which can be rewritten as 1700<x). (Remember, as silly as this may sound, the mouth of the alligator eats the larger part! So the large number has the wide part of the symbol. Remember also that if the sign is < or >, then it includes the number the 'mouth' is facing.) If the forest is up to 2500, you'll generally include 2500 in your equation, so x<2500. This means 1700<x<2500 or x>1700 and x<2500.

Now let's repeat that with the other parts of the question. Mid elevation is x>2500 and x<4000. Subalpine would be x>4000 and x<6500. Alpine is then x>6500 and x< the summit (which is probably the elevation of Mount Rainer in this problem or 14410 feet).

Now we have the question itself. Let's replace x with t for trees for part a. This would mean in the low elevation forest, t>1700 and t<2500 which can be rewritten 1700<t<2500. Now we have flowers in the subalpine AND alpine zones. Let's use f for flowers. If flowers can be in either zone, let's combine them! Because t>4000 and t<6500 in the subalpine level and t>6500 and < the summit (aka 14410 feet), flowers can grow anywhere  above 4000 feet. So flowers would be f>4000 and f<14410. Again, you can combine these into: 400<f<14410.

Sorry this is so long, but I hope it helps :)

There are three companies that produce a critical electronic navigation component (ENC) used in the aerospace industry. These companies are Alice Manufacturing, Byte International, and Cognizant Technologies. Alice makes 85% of the ENCs, Byte makes 10%, and Cognizant makes the remaining 5%. The ENCs made by Alice have a 2.5% rate of defects, the ones made by Byte have a 4.0% rate of defects, and the ones made by Cognizant have a 6% rate of defects. If an ENC is randomly selected from the general population of ENCs, the probability that it was made by Alice is _______. If this ENC is later tested and found to be defective, the probability that it was made by Alice is _______.

Answers

Answer:

a

  [tex]P(A) =  0.85[/tex]

b

  [tex]P(A | D)  =  0.7522 [/tex]

Step-by-step explanation:

From the question we are told that

  The percentage of ENC made by Alice is P(A) 85% = 0.85

  The percentage of ENC made by Byte P(B) 10%=0.10

  The percentage of ENC made by Cognizant P(C) =  5%= 0.05

 The percentage rate of defect of ENC made by Alice is  p  =  2.5 %  =  0.025

  The  percentage rate of defect of ENC made by  Byte is  q =  4.0% = 0.04

 The  percentage rate of defect of ENC made by Cognizant  r =  6% =0.06

 

Generally the probability that a randomly selected ENC will be made by Alice is  

  [tex]P(A) =  0.85[/tex]

Generally the probability that a randomly selected ENC that was found to be defective will be made by Alice is

        [tex]P(A | D)  =  \frac{P(A) *  p}{P(D)}[/tex]

Here

    [tex]P(D)[/tex] is the probability that a randomly selected ENC will be defective and this is mathematically represented as

       [tex]P(D) =  P(A) *  p  +  P(B) *  q  +  P(C) *  r[/tex]

=>     [tex]P(D) =  085 *  0.025   +  0.10  *  0.040  +  0.05  *  0.06[/tex]

=>     [tex]P(D) =  0.02825 [/tex]

So

      [tex]P(A | D)  =  \frac{ 0.85 * 0.025 }{0.02825}[/tex]

=>    [tex]P(A | D)  =  0.7522 [/tex]

Marlina received her salary on Friday. She spent one-half of her salary on rent and then spent $338 on her electric and water bill. Next, she spent one-half of what was left on her phone bill. After spending $56.00 on gas for her car, Marlina had $102.00 left. How much did Marlin spend on rent?

Answers

Answer:

Marlina spent $654 on rent.

Step-by-step explanation:

Let the amount of money Marlina's received for her salary be x.

We know that she spent one-half of her salary on rent and then $338 on her electric and water bill. Therefore, the amount of money she has left can be so far can be represented by:

[tex]\displaystyle x-\frac{1}{2}x-338[/tex]

Next, she spent one-half of what was left on her phone bill. So, we can subtract one-half of the above expression to what we have so far.

[tex]\displaystyle x-\frac{1}{2}x-338-\frac{1}{2}\left(x-\frac{1}{2}x-338\right)[/tex]

Finally, she spent $56 for gas. Thus, we will subtract 56:

[tex]\displaystyle x-\frac{1}{2}x-338-\frac{1}{2}\left(x-\frac{1}{2}x-338\right)-56[/tex]

And we know that after all of the expenses, she will have $102 left. Therefore:

[tex]\displaystyle x-\frac{1}{2}x-338-\frac{1}{2}\left(x-\frac{1}{2}x-338\right)-56=102[/tex]

We want to know how much Marlina spent on rent. So, we can find her salary, since we know the rent is one-half of the salary. To find the salary, we will solve for x.

Distribute:

[tex]\displaystyle x-\frac{1}{2}x-338-\frac{1}{2}x+\frac{1}{4}x+169-56=102[/tex]

Rearrange:

[tex]\displaystyle \left(x-\frac{1}{2}x-\frac{1}{2}x+\frac{1}{4}x\right)+(-338+169-56)=102[/tex]

Combine like terms:

[tex]\displaystyle \frac{1}{4}x-225=102[/tex]

Add 225 to both sides:

[tex]\displaystyle \frac{1}{4}x=327[/tex]

Multiply both sides by 4:

[tex]x=\$ 1308[/tex]

Therefore, Marlina received a total of $1308 for her salary.

We know that she spent half of her salary on rent. Therefore, the amount she spent on rent is:

[tex]\displaystyle r=\frac{1}{2}(1308)=\$ 654[/tex]

Marlina spent a total of $654 on rent.

9514 1404 393

Answer:

  $654

Step-by-step explanation:

Let r represent the amount of Marlina's rent. Since that is half her salary, the amount remaining after paying rent is also equal to r. The disposition of that remaining amount is ...

  $338 on electric and water (E&W)

  (1/2)(r -338) on phone . . . this is half of what is left after paying E&W

  $56 on gas

  $102 unaccounted

__

The total of these amounts is equal to r, so we have ...

  r = 338 + 1/2(r -338) +56 +102

  1/2r = 338 -169 +56 +102 = 327 . . . . . eliminate parentheses, subtract 1/2r

  r = 2(327) = 654 . . . . . multiply by 2 to get r by itself

Marlina spends $654 on rent.

2b.) What transformation of f(x) does y correspond to?

a.) a verticle translation 4 units down
b.) a verticle translation 4 units up
c.) a horizontal translation 4 units to the left
d.) a horizontal translation 4 units to the right

Answers

Answer:

The transformation is " a horizontal translation 4 units to the right " ⇒ (d)

Step-by-step explanation:

Let us revise the translation of a function

If the function f(x) translated horizontally to the right by h units, then its image is g(x) = f(x - h)  If the function f(x) translated horizontally to the left by h units, then its image is g(x) = f(x + h)  If the function f(x) translated vertically up by k units, then its image is g(x) = f(x) + k  If the function f(x) translated vertically down by k units, then its image is g(x) = f(x) - k

Let us look at the graph and choose some points on the f(x) and find their images on y

∵ Point  (1, 2) lies on f(x)

∵ Point (5, 2) lies on y

∵ Point  (3, 8) lies on f(x)

∵ Point (7, 8) lies on y

→ There is no change in the y-coordinates of the points, the change

  only in the x-coordinates

∴ The translation is horizontally

∵  5 - 1 = 4 units ⇒ positive value means to right

∴ f(x) is translated 4 units to the right

The answer is " a horizontal translation 4 units to the right " (d)
