Answer:
Percentile of 20th = 20
Percentile of 25th = 22.5
Percentile of 65th = 28
Percentile of 75th = 29
Explanation:
Sort the numbers in ascending order:
15,20,25,25,27,28,30,34
i = P/100 * N ( i index is the position of the number. Index 1 = 15, index 2 = 20, and so on)
Index of the 20th percentile:
20/100 * 8 = 1.6
Round 1.6 to the next integer = 2
The second number I=20
The 20th percentile is 20
Index of the 25th percentile:
25/100 * 8 = 2
Because 2 is an integer the percentile of 25th is the average of I=20 and I=25
(20+25)/2=22.5
The 25th percentile is 22.5
Index of the 65th percentile
i = 65/100 * 8 = 26.5 = 5.2
Round to the next integer = 6
The 65th percentile is 28
Index of the 75th percentile
I = 75/100 * 8 = 6
Since 6 is an integer (28+30)/2 = 29 percentile
Use the isosceles triangle through them to solve for X
Answer:
122 degs
Explanation:
If that angle is 148 degs, and if the angle next to it is supplementary, that means that you can do 180 - 148 to find the angle next to the given.
The angle by the 148 is therefore 32.
It shows that the 32 + another angle is 90 degs because of the symbol, so the angle by it is 90 -32 = 58.
If the triangle is isosceles, that means that the angle by the x is also 58, due to the two hashes through two legs of the triangle.
If they are also supplementary, you can do 180 - 58 to find the answer.
122.
You can do some other methods, such as using the isosceles legs theorem or something I forgot to find x quickly.

Florida
Elias was just hired to work at the Johnson Space Center, and he will be relocating to Texas. Option A is correct.
Why Texas is significant?Since 2002, Texas has topped the nation in state export revenue and has the second-highest gross state product. If Texas were a sovereign state, it would have the world's tenth-largest GDP.
Several museums along the historic cattle paths commemorate the late-nineteenth-century livestock drives. Cattle grazing is still popular across the state.
For a variety of reasons, Texas is a popular location for working families and retirees. Warm weather, no income tax, and abundance of job prospects are all frequent reasons.

Find the (a) mean, (b) median, (c) mode, and (d) midrange for the data and then (e) answer the given question.
Listed below are the jersey numbers of 11 players randomly selected from the roster of a championship sports team. What do the results tell us?
24 26 89 16 38 69 93 3 1 80 49
The statistical values such as mean, Median and mode gives measure of centre of a data, while the midrange gives information about the spread. Hence, the statistical measures are :
Mean = 44.36Median = 38Mode = 1, 3, 16, 24, 26, 38, 49, 69, 80, 89, 93Midrange = 46Given the data :
1, 3, 16, 24, 26, 38, 49, 69, 80, 89, 93Mean = [Σx ÷ n]
Mean = (24+26+89+16+38+69+93+3+1+80+49) / 11
Mean = (488 ÷ 11) = 44.36
The median :
0.5(n + 1)th termMedian = 0.5(11 + 1) = 6th term
Median = 38
The Mode :
The most frequently occurring value in a distribution ; since each the value occur just one, then there is no single mode value.
The midrange :
(maximum - minimum) / 2Midrange = (93 - 1) / 2
Midrange = 92/2 = 46
Therefore, the midrange is the value of the range divided by 2.
