Mathematics Middle School

Mrs. Chevalier’s class is reviewing by playing a math game. Mrs. Chevalier randomly selects an integer from the set of integers -15 to 15.

Part A

What is the probability that Mrs. Chevalier names a positive integer?

Part B

Explain how you determined your answer.

Answers

Answer 1

Answer:

(15/31) ?

Step-by-step explanation:

|-15| = 15

15+15+1 (for 0) = 31

1 through 15 are positive, so 15 of the 31 could be positive, or 15/31

Sorry, could be wrong, but I think it's right

Answer 2
Part A Answer: The probability that Mrs. Chevalier names a positive integer is a 50% chance.

Part B: Numbers from -15 to 15 is thirty-one total numbers including zero, but zero is neither negative nor positive, so it doesn’t really count in this situation unless the instructions describe it as positive. Without the zero, it is thirty numbers in total, with half of them being negative, and half of them being positive, which can also be said as 50%. You can find this answer by dividing 15 by 30, which is 1/2, or 50%.

Answers

Answer:

[tex]Accept = 69.44\%[/tex]

[tex]Reject = 11[/tex]

Step-by-step explanation:

Given

See attachment for dataset

Solving (a): Percentage to accept

The percentage to accept are flea collars that range between 14mg to 16mg (inclusive)

From the attachment, we have:

[tex]Total = 36[/tex]

[tex]n(14mg-16mg) =25[/tex] --- Number of 14mg to 16mg

So, the percentage to accept is:

[tex]Accept = \frac{n(14mg-16mg)}{Total} * 100\%[/tex]

[tex]Accept = \frac{25}{36} * 100\%[/tex]

[tex]Accept = 0.6944 * 100\%[/tex]

[tex]Accept = 69.44\%[/tex]

Solving (b): Collars to reject

In (a), we have:

[tex]n(14mg-16mg) =25[/tex]

The number to reject is then calculated by subtracting the collars to accept from the total (this is called complement rule)

So, we have:

[tex]Reject = Total - n(14mg - 16mg)[/tex]

[tex]Reject = 36 - 25[/tex]

[tex]Reject = 11[/tex]

11 will be rejected

Answers

Answer:

See below

Step-by-step explanation:

Well, we know the scale is 1 1/2 inches to 4 feet and that one side length of the scaled drawing sqaure is 3 inches, so . . .

3/1 1/2 (3 divided by one and one-half)

to get: 2

Then multiply it by the scale factor of 4

2*4= 8

But remeber, this is only ONE side of the garden, so multiply this by 4

8*4=32  

Next we want to see the number of links it takes to build the garden

Since one link measures 2 2/3 feet you have to divide

32/ 2 2/3 (32 divided by two and two-thirds)

to get an answer of : 12 links

Answer:

∠ ABC = 87°

Step-by-step explanation:

∠ ABD and ∠ DBE are adjacent angles and are supplementary, sum to 180° , so

2x - 17 + x + 32 = 180 , that is

3x + 15 = 180 ( subtract 15 from both sides )

3x = 165 ( divide both sides by 3 )

x = 55

Then

∠ DBE = x + 32 = 55 + 32 = 87° , thus

∠ ABC = ∠ DBE ( vertical angles  )

∠ ABC = 87°

Answers

Answer:

8 = 2x + 4collect like terms8 - 4 = 2x4 = 2xdivide both sides by 24/2 = 2x/2X = 2

Answer:

x=2 (answer should have a positive sign.)

Step-by-step explanation:

To solve this problem, you have to isolate the x from one side of the equation.

First, switch sides.

8=2x+4

2x+4=8

Subtract by 4 from both sides.

2x+4-4=8-4

Solve.

8-4=4

2x=4

Then, divide by 2 from both sides.

2x/2=4/2

Solve.

4/2=2

x=2

The solution is 2.
