Mean ↯[tex] \boxed{ \tt \: mean = \frac{sum \: of \: observations}{total \: number \: of \: observations} }[/tex]
Total number of observations = 9[tex] \sf \rightarrowtail \: mean = \frac{73 + 68 + 73 + 85 + 92 + 81 + 88 + 35 + 48}{9} [/tex]
To make the calculation easier, first add the numbers that sum to multiples of 10

The most occurred number is 73 it has occurred 2 times. Hence, it is the mode!Step-1: Add the data set.
[tex]\bullet \ \ 73 + 68 + 73 + 85 + 92 + 81 + 88 + 35 + 48[/tex]
[tex]\bullet \ \ 643[/tex]
Step-2: Divide the "added" data set by the total digits in the data set.
There are nine digits in the data set.
[tex]\bullet \ \ \frac{643}9}[/tex]
[tex]\bullet \ \ 71.44[/tex]
Thus, the mean of the data set is 71.44.
Solution (Finding the median of the data):Step-1: Arrange the data set in descending form.
Greatest => Smallest
[tex]\bullet \ \ 73, 68, 73, 85, 92, 81, 88, 35, 48[/tex]
[tex]\bullet \ \ 92, 88, 85, 81, 73, 73, 68, 48, 35[/tex]
Step-2: Count the number of digits in the data.
[tex]\bullet \ \ \tex\text{9 digits in total}[/tex]
Step-3: Revise the following.
[tex]\bullet \ \ \tex\text{If there are even number of digits:} \ \frac{\tex\text{(Number of digits)}}{2}[/tex]
[tex]\bullet \ \ \tex\text{If there are odd number of digits:} \ \frac{\tex\text{(Number of digits)} + 1}{2}[/tex]
Step-4: Odd or Even?
[tex]\bullet \ \ \tex\text{Even numbers:} \ 2, 4, 6, 8, 10...[/tex]
[tex]\bullet \ \ \tex\text{Odd numbers:} \ \ 1, 3, 5, 7, \bold{9}, 11...[/tex]
There is an odd number of digits.
Step-5: Use the formula.
[tex]\bullet \ \ \frac{\tex\text{(Number of digits)} + 1}{2}[/tex]
[tex]\bullet \ \ \frac{\tex\text{9} + 1}{2}[/tex]
[tex]\bullet \ \ \frac{\tex\text{10}}{2}[/tex]
[tex]\bullet \ \ 5[/tex]
The fifth digit in the data is the median.
Step-6: Revise the data set.
[tex]\bullet \ \ 92, 88, 85, 81, \bold{73}, 73, 68, 48, 35[/tex]
The median is 73.
Solution (Finding the mode of the data set:The most repeating number is the mode. Let's put the data set in a frequency table.
Step-1: Putting the data set in a frequency table:
~Table attached
Looking at the table, we can tell that 73 has repeated two times and has repeated the most.
The mode is 73.

30x + 100 ≤ 1000
Answers
Answer:
x = 30 employees.
Step-by-step explanation:
30x + 100 = 1000
- 100 - 100
30x = 900
900/30 = 30
Work:
subtract the 100 from the 1000 and then divide that by 30 so 1000-100 is 900/30 is 30

Perimeter = first you need to add 2 and 2 to get the bottom, then you add 2 and 1 to get the side to the left. after that, it's fairly easy. you just add all. The answer should be 14in.
Area of figure = It would be easier to split it then add them. You would need to time 2 by 2 which you should get 4. Then, you would need the length for the bottom, so first, you will need to add 2 and 2 which you get 4 then times that by 1 which should be 2. Add them together and the answer should be 6in.
Figure 2Perimeter = first you need to find the triangle. It said the circle is 3cm. so that means you just got to add 4, 5, and 3 together to get the perimeter of the triangle. Then, for the half-circle, 2[tex]\pi[/tex]3. This should give you 18.85. Then add them together to get 30.85cm.
Area of figure = It would be easier to split it then add them. You would need to figure out what the formula for a triangle is which is [tex]H_{b} B[/tex]/2. This should give you 6. Then you got to figure out the area of the circle, which is [tex]\pi 3^{2}[/tex] which should give you 28.27. then you add them together, which gives you 34.27cm.

Answer:
-1-(-6) = 5
8-(-5) = 13
Step-by-step explanation:
So for the first one -1-(-6), when you have two negatives next to each other then it turns into a plus. So when it turns into a plus we will have -1+6 now although there is a plus sign we are not gonna add because our two numbers have different signs so we are gonna subtract and take the sign of our bigger number and here our bigger number is 6 so our answer will be positive and 6-1=5. So the answer is 5.
Now for the second one 8-(-5), the same thing when you have two negatives next to each other then it turns into a plus. So, when it turns into a plus we will have 8+5. And here they both have the same signs so we are gonna add and 8+5=13. So the answer is 13.
**When I say signs I mean it is either positive or negative, also a positive number if it is at the beginning of the equation then it most likely will not have the plus sign before it.**

the slope of line b is zero because it's parallel to x-axis.
the slope of line c is positive because it makes a angle smaller than 90° with x-axis.
