Answer: If I put a line over the number that means continued Ex: (23.333333..., 3.098888 or 56.77777...)
11. Mean 1 + 2 + 3+ 3+ 4+ 4+ 4+ 5+ 5 / 9 = 31/9 =26.5 .Median 4 Mode 4 Range 5 - 1 = 4. _
12. Mean 6.5 + 7.5 + 7.5 + 7.5+ 8 + 8.5 + 8.5 + 8.5 + 8.5 + 8.5 +9 = 88.5/11 =8.045
median 8.5 mode 8.5 range 9 - 6.5= 2.5
13. Mean 5.75 + 7.25 + 7.75 + 8 = 28.75/4 = 7.1875. median 7.25 + 7.75 = 15/2 = 7.5 range 8 - 5.75 = 2.25
14. Mean 5 + 5 + 6 + 6 + 6 + 7 + 7 + 7 + 7+ 7 = 63/10 = 6.3 median 6 + 7 = 13/2 = 6.5 . mode = 7 range 7 - 5 = 2. _
15. Mean 5 + 5 + 5 + 7+ 7+ 7+ 7 + 7+ 7+ 7/9 = 62/9 = 57.5 median 2 mode 2 range 7 - 5 = 2.
16. 1 + 2 + 2 + 2 + 2 + 2 + 3 + 5 + 5 + 5= 29/10 = 2.9 Median 2 mode 2 range 5 - 1 = 4.
17. 1 +2 + 3 + 5 + 6 + 6+ 6 + 8 + 13 + 19 = 69/10 = 6.9 median 6 mode 6 range 19 - 1 = 18. __
18. 1 + 2 + 2 + 2 + 2+ 2 + 2 + 2 + 4 + 4 + 5 = 27/11 = 2.45 median 2 mode 2 range 4.
Step-by-step explanation:
Mean
Add up all the numbers, then divide by how many numbers there are. Ex: 2, 3, 4. 2 + 3 + 4 = 9. Since there is 3 numbers we divide. 9 divided by 3 equals 3 so 3 is your mean.
Median
Arrange your numbers from least to greatest.
Count how your numbers.
If you have a set of odd numbers, the number in the middle is your median. Ex: 2, 3, 6, 7, 1, . your median is 6.
Mean
If you have a set of even numbers use the 2 numbers in the middle then divide. Ex: 1, 5, 3, 8, 9, 2. The two numbers in the middle are 3 and 8 . 3 plus 8 equals 11. 11 divided by 2 is 5.5. the mean.
Mode
write the numbers from least to greatest. The number that shows the most is your mode. Ex. 4 , 6 ,7 ,3 ,1 3, 3, 3, 2 3, . The number that appears the most is 3. So 3 is the mode. If there is no number that appears more than all the others put NONE or N/A in the blank.
Range
To find the range put the subtract the greatest number and least number. Ex: 2, 4, 7, 1, 8. 1 , 2, 4, 7, 8. 8 mins 1 is 7 so 7 is the range.

Insert two rational numbers between-1/3 and 2/3. with explanation with whole process
Answers
Answer:
Two rational numbers between -1/3 and 2/3 are:
0 and 1/3
Step-by-step explanation:
A rational number is a number that can be written as the quotient of two integer numbers.
Here, we want to find two rational numbers that are between:
-1/3 and 2/3
So, our numbers need to be larger than -1/3 and smaller than 2/3
This is ratter simple, let's start with the lower limit (-1/3) let's add a rational number to it.
Then check, the new number meets the conditions? if not, then we try adding a smaller rational number and so on.
Just because in both cases we have a denominator 3, i will add numbers that also have a denominator of 3.
First try:
Let's try adding 1/3
-1/3 + 1/3 = 0
the number 0 is a rational number: 0 = 0/1
and is true that:
-1/3 < 0 < 2/3
So we already found one of the rational numbers.
Now let's try again, let's add 5/3 this time
-1/3 + 5/3 = (-1 + 5)/3 = 4/3
This is larger than 2/3, so this is not in the desired range.
Let's try again, this time adding 2/3
-1/3 + 2/3 = (-1 + 2)/3 = 1/3
is true that:
-1/3 < 1/3 < 2/3
So the number 1/3 is in the desired range, so we found the second rational number.
You can see that this is kinda a trial and error way to solve these problems, this is the "easier" way to start, as you work with this, eventually you will practice enough and will be easy to find numbers between given ranges.

Answer:
47 -6√10
Step-by-step explanation:
As you know, the area of a square is the square of the side length. It can be helpful here to make use of the form for the square of a binomial.
(a -b)² = a² - 2ab + b²
(√2 -3√5)² = (√2)² - 2(√2)(3√5) + (3√5)²
= 2 - 6√10 + 3²(5)
= 47 -6√10
__
Check
√2-3√5 ≈ -5.29399 . . . . . . . . note that a negative value for side length makes no sense, so this isn't about geometry, it's about binomials and radicals
(√2-3√5)² ≈ 28.02633
47 -6√10 ≈ 28.02633

A jar contains 15 quarters, 9 dimes, 10 nickels and 6 pennies. A coin is selected at random, not replaced, then another coin is selected. Find the probability of the event. P(quarter, then penny)
Answers
Answer: 0.058
Step-by-step explanation:
Number of quarters = 15
Number of dimes = 9
Number of nickels = 10
Number of pennies = 6
Total number of coins = 40
The probability of selecting a quarter first will be 15/40 = 3/8
Since it's not replaced, there'll be 39 coins left and the probability of choosing a penny is 6/39 = 2/13
Therefore, P(quarter, then penny) will be:
= 3/8 × 2/13
= 6/104
= 0.058

Find the measure of x. (to the nearest tenth)
Answers
Trig ratios = sOH, cAH, tOA
In the figure we are finding the opposite and we have the adjacent, therefore we are gonna use the ratio tOA.
tOA states tangent theta (angle) is equal to opposite over adjacent or Tan theta =opp/adj where opp = x and adj = 19
Therefore;
Tan 41 = x/19
Solve for x
x = 19 tan 41

3 × 6 = 18
6 × 3 = 18
9 × 2 = 18
18 × 1 = 18
9 has a perfect square
So,
√18 = √(2*9)
= √2 * √9
= 3√2
√18 = 3√2
Perfect square
1 × 1 = 1
2 × 2 = 4
3 × 3 = 9

In triangle $DEF,$ $\angle D = 30^\circ,$ $\angle F = 60^\circ,$ and $EF = 6.$ Find $DE + DF.$
Answers
Answer:
22.39
Step-by-step explanation:
angle D + angle F + angle E = 180 (angle of triangle)
30 +60 + E = 180
E = 180 - 90
E = 90
so triangle DEF is right angled triangle
we know that,
sin 30 = EF /DF
OR, 1/2 = 6/ DF
OR, DF= 12
again,
cos 30 = De/DF
root3 /2 = DE /12
DE= 10.39
hence DF +DE
= 12 + 10.39
= 22. 39

You're writing the coordinates of the points where the line crosses the axes.
The y-intercept is where the line crosses the y-axis. The y-coordinate there is -6. Because it is the y-axis, the x-coordinate is 0. Written as an ordered pair, the y-intercept is (0, -6).
The x-intercept is where the line crosses the x-axis. The x-coordinate there is -8. Because it is the x-axis, the y-coordinate is 0. Written as an ordered pair, the x-intercept is (-8, 0).
