Answer:

The amount of each person's profit is:

Mack

= $1160

Jason

= $725

Yuri

= $1015

Step-by-step explanation:

Mack, Jason, and Yuri invested a total of $14,500 in the stock market. After one year, they earned a profit equal to 1/5 of their investment Mack receives 2/5 of the profit, Jason Receives 1/4 of the profit, and Yuri receives the rest of the profitWhat is the amount of each person's profit?

Step 1

We calculate how much the profit is.

Mack, Jason, and Yuri invested a total of $14,500 in the stock market. After one year, they earned a profit equal to 1/5 of their investment

The profit = 1/5 of Investment

Hence = 1/5 × $14500

Profit = $2900

Step 2

We calculate the amount each of them receives.

Mack receives 2/5 of the profit,

= 2/5 × $2900

= $ 1160

Jason Receives 1/4 of the profit

= 1/4 × $2900

= $725

Yuri receives the rest of the profit

This is calculated as:

$2900 -($1160 + $725)

$2900 - $1885

= $1015

The amount of each person's profit is:

Mack

= $1160

Jason

= $725

Yuri

= $1015

Answer:

D= It is the total number of data points in the data set, which is also the sum of the row totals or the column totals.

Step-by-step explanation:

The number in the bottom right-hand corner of a two-way frequency table represents D. It is the total number of data points in the data set, which is also the sum of the row totals or the column totals.

When displaying frequencies or relative frequencies for two categorical variables, a two-way table is used. Columns indicate the second category, whereas rows represent the first.

The two-table displays frequencies for two categorical variables in terms of rows and columns.

The number in the bottom right-hand corner of a two-way frequency table represents the total number of data points in the data set, which is also the sum of the row totals or the column totals.

Answer:

I am pretty sure the answer would be $107.31. Sorry if I'm wrong.

Step-by-step explanation:

First you take the total of the 3 DVD's (45.99) and you divide that by 3 (number of DVD's) to get 15.33 which is called the unit price. Then, you take your unit price and multiply that by how many items you are going to buy.

45.99 / 3 = 15.33

15.33 x 7 = 107.31

Answer:

62.

Step-by-step explanation:

A mode is a number that appears most frequently on a set of data. As you can see, there is a double of 62 while the rest is not repeated, so 62 is the mode.

Answer:

a. What is the probability that Carl arrives first?

Probability that Carl arrives first is ¹/₃ = 33.33% since their arrival times is uniformly distributed. The same probability applies to Bob and Alice.

b. What is the probability that Carl will have to wait more than 10 minutes for one of the others to show up?

Assuming that Carl arrived on time, 1:10 PM, we must determine the probability that Alice or Bob arrive between 1:20 and 1:30 (half the remaining time)

P = [3 · (¹/₂ - ¹/₃)] · [3 · (¹/₂ - ¹/₃)] = (3 · ¹/₆) · (3 · ¹/₆) = ¹/₂ · ¹/₂ = ¹/₄ = 25% chance that either Alice or Bob arrive more than 10 minutes later

c. What is the probability that Carl will have to wait more than 10 minutes for both of the others to show up?

P = 1 - 25% = 75%

d. What is the probability that the person who arrives second will have to wait more than 5 minutes for the third person to show up?

I divided the 20 minutes by 5 to get ¹/₄:

P (|S - T| ≤ ¹/₄) = {[(x + ¹/₄)²] / 2} + (1 / 2x) + {[(⁵/₄ - x)²] / 2} = 0.09375 + 0.25 + 0.09375 = 0.4375 = 43.75%

Answer:

x = -1

Step-by-step explanation:

30 = 2.5(10)(-2x)  - you multiply by each

30 = 25 - 5x        - then pass 25 to the other side and subract

5x = - 5x               - then divide 5 / -5

x = -1                     - and you have the answer

Answer:

x= -1

Step-by-step explanation:

distribute 2.5 through the parenthese

30=25-5x

move variable to the left hand side an change its sign

5x+30 =25

move constant to the right hand side and change the sign

5x=25 -30

calculate the difference

5x= -5

divide both sides of the equation by 5

x= -1

200 = 12.5x²

→ Divide both sides by 12.5

16 = x²

→ Square root both sides

Answer:

[tex]g\left(x\right)=x^3\:-\:4x^2\:-\:x\:+\:22[/tex] in the factored form will be:

Step-by-step explanation:

Given the function

[tex]g\left(x\right)=x^3\:-\:4x^2\:-\:x\:+\:22[/tex]

Use the rational root theorem.

[tex]a_0=22,\:\quad a_n=1[/tex]

[tex]\mathrm{The\:dividers\:of\:}a_0:\quad 1,\:2,\:11,\:22,\:\quad \mathrm{The\:dividers\:of\:}a_n:\quad 1[/tex]

[tex]\mathrm{Therefore,\:check\:the\:following\:rational\:numbers:\quad }\pm \frac{1,\:2,\:11,\:22}{1}[/tex]

[tex]-\frac{2}{1}\mathrm{\:is\:a\:root\:of\:the\:expression,\:so\:factor\:out\:}x+2[/tex]

[tex]=\left(x+2\right)\frac{x^3-4x^2-x+22}{x+2}[/tex]

as

[tex]\frac{x^3-4x^2-x+22}{x+2}=x^2-6x+11[/tex]        ∵ [tex]x^3-4x^2-x+22=\left(x+2\right)\left(x^2-6x+11\right)[/tex]

so the expression becomes

[tex]x^3\:-\:4x^2\:-\:x\:+\:22=\left(x+2\right)\left(x^2-6x+11\right)[/tex]

Therefore,

[tex]g\left(x\right)=x^3\:-\:4x^2\:-\:x\:+\:22[/tex] in the factored form will be:

Answer:

[tex]\frac{1}{2}[/tex] of the garden will be radishes.

Step-by-step explanation:

Given a rectangular garden which grows cucumbers in [tex]\frac{2}{3}[/tex] of the garden.

[tex]\frac{3}{4}[/tex] of the cucumber section to grow radishes.

To find:

How much of the whole garden will be radishes?

Solution:

Let the total area of the garden = [tex]x[/tex] sq units

Then as per our assumption, total area to grow cucumbers:

[tex]\frac{2x}{3}[/tex] sq units

Cucumber area to grow radishes = [tex]\frac{3}{4}[/tex] of cucumber area

[tex]= \dfrac{3}{4}\times \dfrac{2x}{3}\\\Rightarrow \dfrac{x}{2}\ sq\ units[/tex]

Fraction of whole garden to grow radishes = Area to grow radishes divided by whole area of garden

[tex]\Rightarrow \dfrac{\frac{x}{2}}{x}\\\\\Rightarrow \bold{\dfrac{1}{2}}[/tex]

Therefore, [tex]\frac{1}{2}[/tex] of the garden will be radishes.

Answer:

The correct option is (d). 2.15 meters.

Step-by-step explanation:

According to the given scenario, the approximate length of an alligator at the 67th percentile is as follows:

The length of an alligator is [tex]X \sim N(2,0.35)[/tex] .

Let us assume the [tex]P_{67}[/tex] be the 67th percentile

[tex]P(X <P67) = 0.67\\\\P(Z < \frac{P_{67 - 2 }}{0.35} ) = 0.67\\\\\emptyset (\frac{P_{67 - 2 }}{0.35} ) = 0.67\\\\ (\frac{P_{67 - 2 }}{0.35} ) = \emptyset^{-1 (0.67)\\\\[/tex]

[tex]\frac{P_{67 - 2 }}{0.35} = 0.44\\\\P_{67} = 2.154[/tex]

Hence, the correct option is (d). 2.15 meters
