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:

75+8n

Step-by-step explanation:

$75 is the constant because that is the amount of money only paid once. $8 is the coefficient because it is multipled by the variable n. The variable is the amount of people going to the bowling alley.

Therefore, to determine the total cost, you need add $75 to the product of 8 and the number of people coming.

Answer:

Step-by-step explanation:

in the first one 2,4,6,and 8 are equal meaning they all equal to 75. the other angles 1,3,5,and 7 equal 105 because 180 - 75 = 105

for the other ones i'm not sure srry

Step-by-step explanation:

1. Alternate Interior Angles are angles made and formed when two parallel or non-parallel lines are intersected by a transversal

2. Corresponding Angles are angles that are in the same position relative to lines intersected by a transversal

3. Alternate Exterior Angles are a pair of angles on the outer side of each of those two lines but on opposite sides of the transversal

4. Using the Corresponding Angle formula, we know that angle x is equivalent to the corresponding angle above it

5. Using the Alternate Exterior Angle formula, we know that the angle y is equal to the 47* angle

6. Supplementary Angles are two angles whose measures add up to 180 degrees.

7. Using the Alternate Exterior Angle formula, we know that the angle w is equal to the 35* angle

What is the volume of the cylinder and i need how you got the answer plz. Thank you

Answers

Answer:

471.24 inches is the volume of the cylinder.

Basically, since the diameter of the cylinder is 10 inches the radius will be 5 inches.

The formula to figure out the volume of a cylinder is V=πr2h.

So using that formula the volume of the cylinder is 471.24 inches.  

Multiply 150 by the substitute your teacher instructed you to use for Pi. The answer will vary, but should be around 471.

V = Pi*R^2*H
V = Pi*5^2*6
V = Pi*25*6
V = Pi*150

Answers

Answer:

2.05x10^4

Step-by-step explanation:

The equation of the line is y=100x+500, which can be found through the given points.

So, if x=200, plug that into the equation of the line. y=100(200)+500

y=20000+500

y=20500

In scientific notation, that is 2.05x10^4

Answers

Answer:

B 236in³

Step-by-step explanation:

you use the equation

V=πr²h/3

π=PI r=Radius h=height

Sense in this problem they give you diameter instead of radius you want to divide it by 2 to get one half.

so the equation used looks like this:

3.14•5²•9/3=235.5

rounded up is 236in³
