Problem 1
The median weight of the Welsh corgis is 27 pounds. This is found in the table in row 1, column 2. Recall that the median is the middle most value, so that means 50% of the Welsh corgi weights will be less than 27 pounds, and also 50% of the weights are greater than 27 pounds.
========================================================
Problem 2
The Welsh corgis have the greater variation in weights. Why is this? There are two pieces of evidence:
The first of which is that the range for the first row (7) is larger than the range in the second row (2). The range is the difference between the max and min. The larger the range, the more spread out the data set will be.
The second piece of evidence is that the MAD (mean absolute deviation) for the Welsh corgis is larger compared to the MAD for the cocker spaniels group. The MAD is another way to measure the spread of a data set. Like the range, the larger the MAD gets, the more spread out the data is. It measures how far on average any given value is from the mean. It's similar to the standard deviation and variance, which are also measures of spread.
========================================================
Problem 3
Both dog breeds have the same mean value, and roughly the same median. Both the mean and median are measures of center. Based on just these two pieces of info alone, we could easily conclude that both dog groups have the same distribution more or less. Furthermore, we could conclude that both groups have roughly the same max weight value.
However, we discussed in problem 2 that the first group (Welsh corgi) is more spread out, so it's likely that could heavily imply that the min and max values are further from the center compared to the second group of dogs. Having a larger max would then mean that the corgi group has the largest weight.
In short, the answer is "Welsh corgi" due to this group having a greater spread, and that pushes the max further away from the center.

Answer:
36degrees
Step-by-step explanation:
2x + 26 = 3x + 21
2x - 3x = 21 - 26
-x = -5
x = 5
m<B = (3x+21)°
m<B = 3(5) + 21
m<B = 15+21

Shiloh is doing a survey to find the time her classmates spend at the beach. She asks the following question:
Which student spends the most time at the beach?
Part A: Describe the data you would expect her to collect from this question.
Part B: Explain whether this is a statistical question. If this is not a statistical question, then modify the question to make it statistical.
Answers
Answer: it is a statistical question
Step-by-step explanation:
Answer:
read the explanation.
Step-by-step explanation:
Part A:
I would expect her to collect a certain number of times, such as: each dot = 1 hour. For example, if she had a dot plot or a chart to divide how much time each student stays at the beach (if that is understandable), along with her collecting the students' names to figure out the answer to her question.
Part B:
This is definitely a statistical question.
A statistical question is a question that can be solved by collecting data that varies.
so this can definitely be solved by collecting data. To even solve this, you need to collect data. The easiest way to solve this is with a dot plot. In my opinion, you also need to gather the students data, such as their names and how many (for example) hours at the beach they spent time there.

Answers
Answer:
2.2
Step-by-step explanation:
If you find the mean of the deviation, you get 2.2
The mean absolute deviation of the data is M = 2.2
What is Mean?The mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.
Mean = Sum of Values / Number of Values
Given data ,
Let the total number of points be n
Now , the value of n = 10
And , the number of points on each data is given by set A
Now , the value of set A = { 7 , 2 , 8 , 5 , 9 , 9 , 5 , 6 , 8 , 1 }
So , the total sum of data = 7 + 2 + 8 + 5 + 9 + 9 + 5 + 6 + 8 + 1
The total sum of data = 60
Now , the mean number of data points = 60/10 = 6
And , the mean deviation is M
M = 1/10 | [ ( 7 - 6 ) + ( 2 - 6 ) + ( 8 - 6 ) + ( 5 - 6 ) + | ( 9 - 6 ) | + ( 9 - 6 ) + ( 5 - 6 ) + ( 6 - 6 ) + ( 8 - 6 ) + ( 1 - 6 ) |
M = ( 1/10 ) [ 1 + 4 + 2 + 1 + 3 + 3 + 1 + 0 + 2 + 5 ]
M = ( 1/10 ) [ 22 ]
M = 2.2
Therefore , the value of M is 2.2
Hence , the mean deviation is 2.2

We can solve this by using the Difference of Squares formula:
(a + b)(a - b) = a² - b²47² - 46², the numerator, is very similar to a² - b², so we can extract 47 as a, and 46 as b.
Rewrite the numerator:
47² - 46²(47 + 46)(47 - 46)(93)(1)93We can use the same formula for the denominator the same way:
17² - 14²(17 + 14)(17 - 14)(31)(3)93Rewrite the fraction and simplify:

Tip:
To find the median number organize the numbers from least to greatest, like this:
40 40 55 55 55 60 60 65 65 70 70 70
Now just cross the numbers in this order: right to left like this:
40 55 55 55 60 60 65 65 70 70
This way you should find the middle number. If you end up with two numbers as the middle you need to add them and divide by 2 to find the average of the two numbers.

Answer:
The model that correctly shows the problem 0.4 divided by 0.2 is option 3.
Step-by-step explanation:
Option 3 has 4 out of 10 rowS shaded in, which you can infer immediately is the correct answer. Since 10 rows represent 1 whole, that means that 4 rows shaded in are 0.4. In option 3, the four rows are split by blue lines and have 2 rows, or 0.2, in each group, so option 3 matches the problem 0.4 divided by 0.2.
