Total number of times rolled = 360

Total number of 2s and 3s = 31 + 49 = 80

P(2 or 3) = 80/360 = 2/9 = 0.22 (nearest hundredth)

Answer: 0.22

Question
If the endpoints of AB have the coordinates A(9,8) and B(-1,-2), what us the midpoint of AB?
Solution 1
midpoint of AB:
x = (9 - 1)/ 2 = 4
y = (8 - 2)/2 = 3

midpoint of AB = (4 , 3)
Solution 2
For this we must use the Midpoint Formula.

m= (\frac{y_2-y_1}{2},  \frac{x_2-x_1}{2})

We'll find the y coordinate first.

y= \frac{y_2-y_1}{2}  \\ y= \frac{8-(-2)}{2}  \\ y= \frac{10}{2}
y=5

Now we'll do the same for x.

x= \frac{x_2-x_1}{2}  \\ x= \frac{9-(-1)}{2}  \\ x= \frac{10}{2}
x=5

Your final answer is m=(5, 5)

Question
A standard number cube with the numbers 1 through 6 is rolled. Find the probability of rolling a number greater than 5 . 1. 1 / 6 2. 1 / 3 3. 1 / 4 4. 2 / 3
Solution 1

The probability of rolling a number greater than 5 is 1/6.

What is probability?

Probability is the ratio that shows the likelihood an event will occur or not from a given set of events.

We can find the probability of rolling a number greater than 5 below:

The total number of faces that have a number greater than 5 = 6.

The total number of faces = 6.

Therefore, the probability of that can be found as shown below:

P( rolling a number greater than 5 ) = The total number of faces that have a number greater than 5/The total number of faces

= 1/6

We have found the probability.

Therefore, we have found that the probability of rolling a number greater than 5 is 1/6.

Solution 2
Hello!

To find the probability you put the amount of favorable outcomes over the total amount of outcomes

The cube has numbers 1 - 6 on it

Only 1 number is greater than 5 (6)

That gives us 1 favorable outcome and 6 total outcomes

The answer is A) 1/6

Question
It takes Wayne 1/10 hours to walk a 1/6 mile park loop. What is Wayne's unit rate, in miles per hour
Solution 1
To solve this problem, we should set up a proportion, letting x represent our unknown number of miles that Wayne walks in one hour.

1/6 mile / 1/10 hours = x miles / 1 hour

Now we use cross-products or the multiplication of the numerator of one fraction times the denominator of the other fraction, setting these two numbers equal. 聽The resulting equation is:

1/6 = 1/10x

Finally, we must divide both sides by 1/10 to cancel it out on the right side of the equation and get the variable x alone.

x = 5/3 or 1 2/3

Therefore, Wayne walks 1 2/3 miles per hour.

Question
You are given the following list of values: 5.8, 6.1, 4.9, 10.9, 0.8, 6.1, 7.4, 10.2, 1.1, 5.2, 5.9 Which values are outliers?
Solution 1
To find the outlier your have to find the IQR( interquartile range), the upper fence and the lower fence. The IQR is the difference between the first and third Quartile. Q3(7.4) -Q1(4.9)= 2.5. Use the IQR to find the Upper fence and Lower fence.
Upper fence- (7.4)+1.5(2.5)= 11.15
Lower fence- (4.9)-1.5(2.5)= -1.15
Make sure your values are in the right order so you can see what numbers are below or above the Upper and lower fences.聽 There are no outliers.

Question
If the least value of n is 4, which inequality best shows all the possible values of n? n 鈮 4 n 鈮 4 n < 4 n > 4
Solution 1
Comment
If the least value of n is 4 that means that 4 is one of the numbers in whatever it is that you are describing. In other words n = 4 is part of your answer. If that is the case, the last two values are incorrect because 4 is not included in either one of them.

Discussion
So that means that you have to choose between one of the first 2. The key word is least. It means that the lowest possible value is 4. Nothing is lower.聽

When you write something like n聽鈮 4 what you are saying is the n must be = to or less than 4. The arrow head points to the smallest number which, in this case, is n.聽

But the question says that the least number is 4. So the arrowhead must point towards the 4. This we have that n must be larger than 4.聽

Conditions
There are 2 conditions to this problem
n must be greater than 4
n can equal 4. It is the smallest number.
