You must read 130 pages for homework. Reading at the same rate as the previous question, can you complete the assignment in two hours?

Answers

What is the previous question?
You can’t answer without it.

Answer:

Since you must read 52 page per hour, and there is 2 hours to complete assignment, then you will do this:

52 + 52 = 104

You would be able to read 104 pages in 2 hours, which is less than 130, so you would NOT be able to complete the assignment.

Answer:

a. 12

b. 1/2

Step-by-step explanation:

Given a meal has 3 choices of meat, 2 choices of fruit, and 2 choices of dessert, you want to know the number of possible meals, and the probability of a meal with no cookie for dessert.

a. Possibilities

As the tree diagram shows, the number of possible meals is ...

(possible meats)×(possible fruits)×(possible desserts)

= 3×2×2 = 12

There are 12 possible lunch options.

b. Cookies

Half the possible dessert choices have no cookie. That is the probability that a lunch will have no cookie:

P(no cookie) = 1/2

Additional comment

The bottom line of the tree diagram has 6 Cs and 6 Ms. That is, 6 of the 12 options for meals have no cookie.

The diagram below shows the number of ice cream cones sold in a day at a local ice cream shop.

Based on these results what is the most reasonable prediction of the number of chocolate chip ice cream cones that will be sold out of the next 240 cones sold?

Answers

Answer:

Step-by-step explanation:

B-60

EXPLANATION:

If he sold 8 vanilla, 28 double scoop and 12 chocolate chip, it means he sold 12 chocolate chip out of 48. So he sold 12/48 chocolate chip, which equals 1/4. If we write it in percentages, we will see that 1/4•100%=25%. Now we need to know how many chocolate chips would be sold in next 240 cones. In conclusion, we need to calculate 25% of 240. So if 240 is 100% and X is 25%, then 240•25=100X. If we solve that equation, we will see that X=60, so 25% of 240 equals 60. In conclusion, the right answer is B.

Tom and Katherine live in different towns which are linked by a bike trail. They agree to meet for a bike ride, and both set off from home at the same time. Tom rides north at a speed of 14 mph and Katherine rides south at 10 mph. The bike trail between their homes is 42 miles long. How long will it be before they meet?

Answers

Answer:

We can start by using the formula:

time = distance / speed

Let t be the time (in hours) for Tom and Katherine to meet.

Tom's distance = Tom's speed x time = 14t

Katherine's distance = Katherine's speed x time = 10t

Since they are riding towards each other, the total distance they cover is the sum of their distances:

Tom's distance + Katherine's distance = 42 miles

14t + 10t = 42

Simplifying:

24t = 42

t = 42 / 24

t = 1.75 hours

Therefore, Tom and Katherine will meet after 1.75 hours of riding.

They will meet in 1.75 hours

A simulation of a person throwing a dart at a dartboard is run 140 times, and the player hits the dartboard 105 times. Using the results of the simulation, what is the experimental probability that the player does not hit the dartboard? Express your answer as a decimal.

Can someone please help me i am so confused.

Answers

Answer:

0.25

Step-by-step explanation:

If the person made it 105 out of 140 times, that can be written as a fraction: 105/140

Then, you just turn the fraction into a decimal by dividing the numerator by the denominator.

105 divided by 140 = 0.75

0.75 is the probability that it does hit the board, so we can subtract 0.1-0.75 to give us the probability that is doesn't hit the board. This would give us 0.25

Hope this helps

The experimental probability that the player does not hit the dartboard is,

⇒ 1 / 14

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;

A simulation of a person throwing a dart at a dartboard is run 140 times, and the player hits the dartboard 105 times.

Hence, Number of not hit dartboard is,

⇒ 140 - 105

⇒ 35

Thus, The experimental probability that the player does not hit the dartboard is,

⇒ 35 / 140

⇒ 7 / 28

⇒ 1 / 14

An investor has an account with stock from two different companies. Last year, his stock in Company A was worth $6100 and his stock in Company B was worth $6480. The stock in Company A has decreased 2% since last year and the stock in Company B has decreased 10%. What was the total percentage decrease in the investor's stock account? Round your answer to the nearest tenth (if necessary).

Answers

Investment in Company A by investor = $6100

Investment in Company B by investor = $6480

The decrease in value of the stock of company A is 2%

The decrease in value of the stock of company B is 10%

Value of wealth that investor lost in company A = 6100× 2/100

= 61×2

= $122

The decline in the value of the stock of company B = 6480×10/100

= 648×1/1

= $648

The total decline in the wealth of the investor= 122+648

= $770

The combined wealth of investor in both companies= 6100+6480

= $12580

Percentage of decline in the stock account of investor= 770×100/12580

= 77000/12580

= 6.1%

The total percentage decline in investor's stock account is 6.1%

The stem-and-leaf plot displays data collected on the size of 15 classes at two different schools.

0 3 0, 6
Key: 2 | 1 | 0 means 12 for Mountain View and 10 for Seaside

Part A: Calculate the measures of center. Show all work. (2 points)

Part B: Calculate the measures of variability. Show all work. (1 point)

Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning. (1 point)

Answers

To calculate the measures of center, we need to find the mean and median for each school.

For Mountain View School:
Data: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 0 + 1 + 2 + 3 + 4 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 8 + 8 + 8 + 9) / 19
= 100 / 19
≈ 5.26

To find the median, we need to arrange the data in ascending order: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5

For Seaside School:
Data: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 1 + 1 + 2 + 2 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 7 + 8 + 8 + 8 + 9) / 19
= 80 / 19
≈ 4.21

To find the median, we need to arrange the data in ascending order: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5

Now let's calculate the measures of variability, specifically the range and interquartile range (IQR).

Range: The range is the difference between the largest and smallest values in the dataset.

For Mountain View School:
Range: 9 - 0 = 9

For Seaside School:
Range: 9 - 0 = 9

Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1) and measures the spread of the middle 50% of the data.

For Mountain View School:
Q1 = 3
Q3 = 7
IQR = Q3 - Q1 = 7 - 3 = 4

For Seaside School:
Q1 = 2
Q3 = 7
IQR = Q3 - Q1 = 7 - 2 = 5

To determine which school is a better choice for a smaller class size, we can consider both the mean and the median.

Both the mean and median for Mountain View School are higher than those for Seaside School. This suggests that, on average, the class sizes at Mountain View School are larger than those at Seaside School. Therefore, if you are interested in a smaller class size, Seaside School would be a better choice

Part A:

For Mountain View School:
- Median: The median class size is the middle value, which is 25.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (29 + 28 + 28 + 27 + 25 + 24 + 24 + 23 + 21 + 20 + 19 + 18 + 15 + 13 + 10) / 15 = 21.27.

For Seaside School:
- Median: The median class size is the middle value, which is 20.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (25 + 25 + 27 + 27 + 28 + 28 + 28 + 30 + 31 + 35 + 36 + 38 + 40 + 43 + 45) / 15 = 31.13.

Part B:

For Mountain View School:
- Range: The range is the difference between the largest and smallest values, which is 29 - 10 = 19.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 20 and Q3 is 28. Therefore, the IQR is 28 - 20 = 8.

For Seaside School:
- Range: The range is the difference between the largest and smallest values, which is 45 - 25 = 20.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 27 and Q3 is 38. Therefore, the IQR is 38 - 27 = 11.

Part C:

If you are interested in a smaller class size, Mountain View School is a better choice for you because it has a lower mean and median class size than Seaside School.

Answer:

y = 1 + -1Y

Step-by-step explanation:

Simplifying

13y + 2 + -2y = 10y + 3 + -1Y

Reorder the terms:

2 + 13y + -2y = 10y + 3 + -1Y

Combine like terms: 13y + -2y = 11y

2 + 11y = 10y + 3 + -1Y

Reorder the terms:

2 + 11y = 3 + -1Y + 10y

Solving

2 + 11y = 3 + -1Y + 10y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-10y' to each side of the equation.

2 + 11y + -10y = 3 + -1Y + 10y + -10y

Combine like terms: 11y + -10y = 1y

2 + 1y = 3 + -1Y + 10y + -10y

Combine like terms: 10y + -10y = 0

2 + 1y = 3 + -1Y + 0

2 + 1y = 3 + -1Y

Add '-2' to each side of the equation.

2 + -2 + 1y = 3 + -2 + -1Y

Combine like terms: 2 + -2 = 0

0 + 1y = 3 + -2 + -1Y

1y = 3 + -2 + -1Y

Combine like terms: 3 + -2 = 1

1y = 1 + -1Y

Divide each side by '1'.

y = 1 + -1Y

Simplifying

y = 1 + -1Y

In a right triangle, apart from the right angle, the other two angles are

x + 1 and 2x + 5. find the angles of the triangle.

Answers

Answer:

The two other angles are 29 degrees and 61 degrees

Step-by-step explanation:

There are 180 degrees in a triangle. Given this is a right triangle one of the angles is 90 degrees. As in the other two angles have to equal up to 90 degrees. Now we have to find x.

180 - 90 = 90

If x equals 28

28 + 1 = 29

2 x 28 + 5 = 61

29 + 61 = 90

The two other angles are 29 degrees and 61 degrees

Answer:

29 , 61

Step-by-step explanation:

Sum of all angles of a triangle = 180

90 + x + 1 +2x +5 = 180 {Combine like terms}

96 + 3x = 180 {Subtract 96 from both sides}

3x = 180 - 96

3x = 84 {Divide both sides by 3}

x = 84/3

x = 28

x +1 = 28 +1 = 29

2x +5 = 2*28 + 5 = 56 + 5 = 61
