10. Part A)

The jazz band sells 31 large boxes of fruit and 74 small boxes of fruit.

For each large fruit box, the price is $20 and cost is $x.

Profit is defined as Price - Cost.

So, profit for one large fruit box = 20 - x

Profit for 31 large fruit boxes = 31(20 - x)

Price of each small fruit box is $10 and cost of each small fruit box is $y. The profit for each small fruit box is 10 - y.

Profit for 74 small fruit boxes = 74(10 - y)

The total profit for 31 large boxes and 74 small boxes will be:

Total profit = 31 (20 - x ) + 74(10 - y)

Using distributive property, we can simplify the above equation as:

Total profit = 31(20) - 31x +74(10) - 74y

Total profit = 1360 - 31x - 74y

Part B)

Cost of each large box is given to be $9. This means x = 9

Cost of each small box is given to be $4. This means y = 4

Using the values of x and y in the profit equation we can find the profit of the Jazz Band.

So, Jazz Band's Profit = 1360 - 31(9) - 74(4)

Jazz Band's Profit = $ 785

Thus the profit of Jazz Band will be $785.

2. Ally scored 5 more than 7 times as many points as Gaelle during the weekend
basketball game. If they scored 45 points, how many did Ally score?
You must solve algebraically.

Answers

Answer:

Step-by-step explanation:

1.

L=4W-1

P=2(L+W)=118, using L from above makes this

2(4W-1+W)=118,

2(5W-1)=118

5W-1=59

5W=60

W=12, and since L=4W-1

L=4(12)-1

L=47

So the length is 47ft and the width is 12ft

2.

A=7G+5

7G=A-5

G=(A-5)/7, and we are told A+G=45, using G=(A-5)/7 gives us

A+(A-5)/7=45

(7A+A-5)/7=45

(8A-5)/7=45

8A-5=315

8A=320

A=40

So Ally scored 40 points.

If you choose a random juice from the cooler and a random sandwich from the bag, what is the probability you get orange juice and a ham sandwich? Round your answer to the nearest hundredth (2 decimal places).

Answers

Answer:

10/117 or 8.55% or 0.09

Step-by-step explanation:

5/13 x 2/9 = 10/117

The probability you get orange juice and a ham sandwich is,

⇒ 10/117

What is mean by Probability?

The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one

Given that;

In a cooler there are 5 orange juices, 2 apple juices and 6 grape juices. In a large bag there are 2 ham sandwiches and 7 turkey sandwiches.

Hence, Total number of juice in a cooler = 5 + 2 + 6 = 13

And, Total number of sandwiches = 2 + 7 = 9

Thus, The probability you get orange juice and a ham sandwich is,

⇒ 5 / 13 × 2 / 9

⇒ 10/117

(a) P(two red marbles) with replacement without replacement (b) P(two black marbles) with replacement without replacement (c) P(one red and one black marble) with replacement without replacement (d) P(red on the first draw and black on the second draw) with replacement without replacement

Answers

Answer:

For probabilities with replacement

[tex]P(2\ Red) = \frac{25}{64}[/tex]

[tex]P(2\ Black) = \frac{9}{64}[/tex]

[tex]P(1\ Red\ and\ 1\ Black) = \frac{15}{32}[/tex]

[tex]P(1st\ Red\ and\ 2nd\ Black) = \frac{15}{64}[/tex]

For probabilities without replacement

[tex]P(2\ Red) = \frac{5}{14}[/tex]

[tex]P(2\ Black) = \frac{3}{28}[/tex]

[tex]P(1\ Red\ and\ 1\ Black) = \frac{15}{28}[/tex]

[tex]P(1st\ Red\ and\ 2nd\ Black) = \frac{15}{56}[/tex]

Step-by-step explanation:

Given

[tex]Marbles = 8[/tex]

[tex]Red = 5[/tex]

[tex]Black = 3[/tex]

For probabilities with replacement

(a) P(2 Red)

This is calculated as:

[tex]P(2\ Red) = P(Red)\ and\ P(Red)[/tex]

[tex]P(2\ Red) = P(Red)\ *\ P(Red)[/tex]

So, we have:

[tex]P(2\ Red) = \frac{n(Red)}{Total} \ *\ \frac{n(Red)}{Total}\\[/tex]

[tex]P(2\ Red) = \frac{5}{8} * \frac{5}{8}[/tex]

[tex]P(2\ Red) = \frac{25}{64}[/tex]

(b) P(2 Black)

This is calculated as:

[tex]P(2\ Black) = P(Black)\ and\ P(Black)[/tex]

[tex]P(2\ Black) = P(Black)\ *\ P(Black)[/tex]

So, we have:

[tex]P(2\ Black) = \frac{n(Black)}{Total}\ *\ \frac{n(Black)}{Total}[/tex]

[tex]P(2\ Black) = \frac{3}{8}\ *\ \frac{3}{8}[/tex]

[tex]P(2\ Black) = \frac{9}{64}[/tex]

(c) P(1 Red and 1 Black)

This is calculated as:

[tex]P(1\ Red\ and\ 1\ Black) = [P(Red)\ and\ P(Black)]\ or\ [P(Black)\ and\ P(Red)][/tex]

[tex]P(1\ Red\ and\ 1\ Black) = [P(Red)\ *\ P(Black)]\ +\ [P(Black)\ *\ P(Red)][/tex]

[tex]P(1\ Red\ and\ 1\ Black) = 2[P(Red)\ *\ P(Black)][/tex]

So, we have:

[tex]P(1\ Red\ and\ 1\ Black) = 2*[\frac{5}{8} *\frac{3}{8}][/tex]

[tex]P(1\ Red\ and\ 1\ Black) = 2*\frac{15}{64}[/tex]

[tex]P(1\ Red\ and\ 1\ Black) = \frac{15}{32}[/tex]

(d) P(1st Red and 2nd Black)

This is calculated as:

[tex]P(1st\ Red\ and\ 2nd\ Black) = [P(Red)\ and\ P(Black)][/tex]

[tex]P(1st\ Red\ and\ 2nd\ Black) = P(Red)\ *\ P(Black)[/tex]

[tex]P(1st\ Red\ and\ 2nd\ Black) = \frac{n(Red)}{Total} *\ \frac{n(Black)}{Total}[/tex]

So, we have:

[tex]P(1st\ Red\ and\ 2nd\ Black) = \frac{5}{8} *\frac{3}{8}[/tex]

[tex]P(1st\ Red\ and\ 2nd\ Black) = \frac{15}{64}[/tex]

For probabilities without replacement

(a) P(2 Red)

This is calculated as:

[tex]P(2\ Red) = P(Red)\ and\ P(Red)[/tex]

[tex]P(2\ Red) = P(Red)\ *\ P(Red)[/tex]

So, we have:

[tex]P(2\ Red) = \frac{n(Red)}{Total} \ *\ \frac{n(Red)-1}{Total-1}[/tex]

We subtracted 1 because the number of red balls (and the total) decreased by 1 after the first red ball is picked.

[tex]P(2\ Red) = \frac{5}{8} * \frac{4}{7}[/tex]

[tex]P(2\ Red) = \frac{5}{2} * \frac{1}{7}[/tex]

[tex]P(2\ Red) = \frac{5}{14}[/tex]

(b) P(2 Black)

This is calculated as:

[tex]P(2\ Black) = P(Black)\ and\ P(Black)[/tex]

[tex]P(2\ Black) = P(Black)\ *\ P(Black)[/tex]

So, we have:

[tex]P(2\ Black) = \frac{n(Black)}{Total}\ *\ \frac{n(Black)-1}{Total-1}[/tex]

We subtracted 1 because the number of black balls (and the total) decreased by 1 after the first black ball is picked.

[tex]P(2\ Black) = \frac{3}{8}\ *\ \frac{2}{7}[/tex]

[tex]P(2\ Black) = \frac{3}{4}\ *\ \frac{1}{7}[/tex]

[tex]P(2\ Black) = \frac{3}{28}[/tex]

(c) P(1 Red and 1 Black)

This is calculated as:

[tex]P(1\ Red\ and\ 1\ Black) = [P(Red)\ and\ P(Black)]\ or\ [P(Black)\ and\ P(Red)][/tex]

[tex]P(1\ Red\ and\ 1\ Black) = [P(Red)\ *\ P(Black)]\ +\ [P(Black)\ *\ P(Red)][/tex]

[tex]P(1\ Red\ and\ 1\ Black) = [\frac{n(Red)}{Total}\ *\ \frac{n(Black)}{Total-1}]\ +\ [\frac{n(Black)}{Total}\ *\ \frac{n(Red)}{Total-1}][/tex]

So, we have:

[tex]P(1\ Red\ and\ 1\ Black) = [\frac{5}{8} *\frac{3}{7}] + [\frac{3}{8} *\frac{5}{7}][/tex]

[tex]P(1\ Red\ and\ 1\ Black) = [\frac{15}{56} ] + [\frac{15}{56}][/tex]

[tex]P(1\ Red\ and\ 1\ Black) = \frac{30}{56}[/tex]

[tex]P(1\ Red\ and\ 1\ Black) = \frac{15}{28}[/tex]

(d) P(1st Red and 2nd Black)

This is calculated as:

[tex]P(1st\ Red\ and\ 2nd\ Black) = [P(Red)\ and\ P(Black)][/tex]

[tex]P(1st\ Red\ and\ 2nd\ Black) = P(Red)\ *\ P(Black)[/tex]

[tex]P(1st\ Red\ and\ 2nd\ Black) = \frac{n(Red)}{Total} *\ \frac{n(Black)}{Total-1}[/tex]

So, we have:

[tex]P(1st\ Red\ and\ 2nd\ Black) = \frac{5}{8} *\frac{3}{7}[/tex]

[tex]P(1st\ Red\ and\ 2nd\ Black) = \frac{15}{56}[/tex]

==========================================================

Explanation for problem 1

If all we're concerned with are the trout in this river, and this river only, then we are measuring the parameter population mean value of 60 cm. Parameters always go with populations; while statistics go with samples.

A quick way to remember:

parameter and population both start with pstatistic and sample both start with s

----------------------------------------------------------

Explanation for problem 2

This question seems to be missing a key word. The portion that reads "then which is not a possible for the study?" seems to have a missing word where the blank is shown below

then which is not a possible _____ for the study?

I think "population" should be put into the blank. If that's the case, then choices A, B, and D are all possible populations here. They are larger than the sample of freshmen at this high school. Notice how the students in Ms. Anderson's class is a smaller set compared to the set of all freshmen at Hamilton High School. The sample must always be smaller than the population, or phrased another way, the population must always be larger than the sample.

So this is why choice C is the answer.

Answer:

x = 25

Step-by-step explanation:

Looking at the triangle we know that it is a right triangleor a 90⁰ triangle.

(2x + 15)⁰ + x⁰ = 90⁰

2x + 15⁰ + x⁰ = 90⁰

2x + x + 15⁰ = 90⁰

3x + 15⁰ = 90⁰

3x + 15⁰ - 15⁰ = 90⁰ - 15⁰

3x = 75⁰

3x / 3 = 75⁰ / 3

x = 25⁰

Now plug the x value in the missing angles.

2x + 15⁰

2(25⁰) + 15⁰

50⁰ + 15⁰

65⁰

According to the sum of triangle, all angles add up to 180⁰. Even though this is a right triangle, it should add up 180⁰ in order to be a triangle.

65⁰ + 25⁰ + 90⁰ = 180⁰
