A set of data has 50 observations. How many classes would you recommend?
Answers
Answer:
6 classesStep-by-step explanation:
If k is the number of classes and n is the number of observations, then for number of classes we should select the smallest k such that 2^k > n.
We have n = 50 and:
2^5 = 32 < 502^6 = 64 > 50As per above described 2 to k rule, we are taking k = 6.
So 6 classes should be used.

Step-by-step explanation:
Divide the distance by the time.
Blue Wildebeest: 33 1/3 divided by 2/3 = 50
Brown Hare: 8 divided by 1/6 = 48
Cheetah: 7 divided by 1/10 = 70
Elk: 18 divided by 2/5 = 45
Now you have to order the animals from who has the biggest number(top) to who has the smallest number (bottom).
Answer:

Cheetah
Step-by-step explanation:
Divide the distance by time to make percent
Blue Wildebeast- 33 1/3 ÷ 2/3 = 50%
Brown Hare- 8 ÷ 1/6 = 48%
Cheetah- 7 ÷ 1/10 = 70%
Elk- 18 ÷ 2/5 = 45 %
Least to Greatest: 45%, 48%, 50%, 70%

We are going to convert each fraction to decimal form to make it easier to tell if the statement is true or false
[tex]\frac{2}{3} =.66\\\\\frac{2}{6}=.33[/tex]
.66 is greater than .33 therefore [tex]\frac{2}{3} >\frac{2}{6}[/tex] is a true statement
[tex]\frac{8}{10} =.8\\\\\frac{6}{5} =1.2[/tex]
1.2 does not equal 8 therefore [tex]\frac{8}{10} =\frac{6}{5}[/tex] is a false statement
[tex]\frac{1}{8} =.125\\\\\frac{1}{4}=.25[/tex]
.25 is greater than .125 therefore [tex]\frac{1}{8} <\frac{1}{4}[/tex] is a true statement
[tex]\frac{2}{4} =.5\\\\\frac{1}{2} =.5[/tex]

Why might Razis method not be a good way to estimate the probability? My team won 18 of their last 20 matches, so the probability that they will win their next match is 18/20 = 90%
Answers
Answer:
It is a really idealistic way to estimate probability.
It usually works well for random events where there is no restriction like:
"There are N elements in a set, the probability of randomly selecting any element is the same (so there is no restriction) meaning that for every single element, the probability is 1/N.
Now suppose that there are K elements (K < N) with a given characteristic, then the probability of randomly selecting one of the K elements out of the sett with N elements is equal to K times the probability of each element, this is:
P = K*(1/N) = K/N"
Then if a dice has 6 possible outputs, and we want to find the probability of getting a 3 or a 5, we need to find the quotient between the outcomes where we get a 3 or a 5 (2) and the total number of outcomes (6)
P = 2/6
Now let's go to the case in the problem:
We know that out of the last 20 games, your team won 18.
Then yes, your team won (18/20)*100% = 90% of their played games.
Does this mean tath the probability of winning the next game is 90%?
Well no, because this is not a random selection, there are a lot of other things needed to analyze, as the win rate of the other team (suppose that the other team won 14 of their last 20 games, then their win rate is (16/20)*100% = 70%
Does this mean that the probability where our team wins is 90%, and the probability of the enemy team winning is 70%?
Well no, this makes no sense at all, and this is why this method is not a good way to estimate probability in complex cases like this one.

Maggie draws a triangle with a right angle. The other two angles have equal measures. What are the possible values of the exterior angles for Maggie's triangle? Explain.
Answers
Answer:
135°, 135° and 90°
Step-by-step explanation:
It is given a triangle with a right angle (90°) and the other two angles have equal measures, so they are both (45°)
exterior angles are thus 180 - 45, 180 - 45, 180 - 90
which are 135°, 135° and 90°.
