a. Write the ratio that compares the appearances made by the Rangers to the appearances made by the Canadiens in simplest form. Then explain its meaning​

Answers

Answer:

Step-by-step explanation:

Important fact: much as I hate to admit it, in all professional sports, there is no team that has made as many appearances in the sports final as the Canadiens.

The ratio you want is 10/32 = 5/16.

The ratio means that for every 5 appearances the rangers made, the Canadiens made 16 appearances.

inches. What is the area of the circle?
A=2

Answers

Answer:

B

Step-by-step explanation:

hopefully it makes sense and is visible:)

Answer:  9pi  (choice B)

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

Work Shown:

C = 2*pi*r .... circumference equation

6pi = 2pi*r .... replace C with the given circle perimeter

6 = 2r .... divide both sides by pi, they cancel

6/2 = r

3 = r

r = 3 ... is the radius

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

A = pi*r^2 .... area of circle equation

A = pi*3^2

A = pi*9

A = 9pi .... which points to choice B as the final answer

Nikki's cousin lives 60 miles away, so Nikki decided
to take the train to visit him. If the trip took
2 hours, how many miles per hour did the train
travel?

Answers

Answer:

30

Step-by-step explanation:

just divide 60 by 2

If the distance between Nikki's cousin and Nikki is 60 miles and covered in 2 hours then the speed of the train is 30 miles per hour.

What is speed?

The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.

We know that the speed formula

[tex]\rm Speed = \dfrac{Distance}{Time}[/tex]

Nikki's cousin lives 60 miles away, so Nikki decided to take the train to visit him. If the trip took 2 hours. Then the speed of the train will be

[tex]\rm Speed = \dfrac{60}{2}\\\\Speed = 30 \ miles/hour[/tex]

A bag has 14 yellow marbles and 4 red marbles. Half of the red marbles are made of glass. A marble is selected at random from the bag. What is the probability that it is a red, glass marble?

Answers

Answer:

2/18, or 1/9

Step-by-step explanation:

Lets start by finding out how many red, glass marbles there are.

Half of the red marbles of glass, and there are four red marbles. All we need to do is divide 4 by 2.

4/2=2

There are two glass marbles.

Now we just need to add the number of red marbles to yellow marbles. That would be 14+4, which is 18.

In conclusion, there are 2 red marbles, and 18 marbles in total, so it would be 2/18. Simplified, it would be 1/9.

: 2(2x-7)+2(4x+3)=112

Step-by-step explanation:

Answer: Third Choice. 112 = 2 (2x - 7) + 2 (4x + 3)

Concept:

Here, we need to know how to find the perimeter of a rectangle.

Perimeter (rectangle) = 2l + 2w

l = length

w = width

Solve:

Given information

l = 2x - 7

w = 4x + 3

Perimeter = 112 cm

Given expression

Perimeter = 2l + 2w

Substitute values into the expression

[tex]\boxed{112 = 2 (2x - 7) + 2 (4x + 3)}[/tex]

Expand parentheses

112 = 4x - 14 + 8x + 6

Combine like terms

112 = (4x + 8x) + (6 - 14)

112 = 12x - 8

Add 8 on both sides

112 + 8 - 12x - 8 + 8

120 = 12x

Divide 12 on both sides

120 / 12 = 12x / 12

A jar contains some number of pennies. When pennies are removed 2, 3, 4, 5, 6 or 8 at a
time, one penny is left over. There are no pennies left over when they are removed 7 at a
time. What is the least number of pennies that could be in the jar?

Answers

Answer:

721.

Step-by-step explanation:

The total number must be a multiple of 7

One less than the number is the LCM of 2 3 4 5 6 and 8.

The LCM is worked out as follows

2

3

4 = 2*2

5

6 = 2*3

8 = 2*2*2

LCM = 2*2*2* 3*5 = 120

But 121 is not divisible by 7 so it must be a multiple of 120 + 1 which is divisible by 7.

240 + 1 = 241 - not divisible by 7

480 + 1  = 481 - not divisible by 7

720 + 1 = 721

721/7 = 103

Answer:

Step-by-step explanation:

Let say n the number of pennies in the jar.

n is a multiple of 7 : n=7*k

n-1 is a multiple of 2,3,4,5,6,8 so a multiple of the lcm= 120

n-1=120*t

n-1=120*t

n=7*k

120*t=7k-1

7k=120*t+1

[tex]k=\dfrac{120*t+1}{7}\\k=17*t+\dfrac{t+1}{7}\\t=6+7*a\\k=17*(6+7a)+\frac{6+7*a+1}{7} =102+119*a+1+a=103+120*a\\n=7*k=7*(103+120*a)=721+840a\\\\[/tex]

The least number of pennies is 721 (when a=0)

Proof:

n-1=720

720/2=360

720/3=240

720/4=180

720/5=144

720/8=90

721/7=103

Is the mean greater than, less than, or equal to the median? Explain your reasoning.

Answers

Answer:

equal to

Step-by-step:

Again, the mean reflects the slanted the most.

To summarize, generally if the distribution of data is slanted to the left, the mean is less than the median, which is often less than the mode. If the distribution of data is slanted to the right, the mode is often less than the median, which is less than the mean.

Answer:

Equal

Step-by-step explanation:

The median is the midmoint of all points (as many values below as above this value). The mean is the (sum of values) / (count of values). Since every value has the exact same count, the mean and median will be the same.
