I think the right triangle is on the top of the picture aisle that is the only one that look right to me
B: 914-20(27.80)=X, multiply: 20(27.80)=556, 914-556=$358 :A.
C: 914-27.80=$886.20 :)
2 and 5 8th Convert to improper fraction.
so, after you convert it. It should be like this
11/12 divided by 21/8
then use reciprocal so it will be
11/12 multiply by 8/21
then you got 88/252
then simplify it, 88 divided 4, and 252 divided 4
so the answer is 22/63.
A = 1/2bh...multiply both sides by 2
2A = bh...divide both sides by b
(2A)/b = h
s = 1/2gt^2...multiply both sides by 2
2s = gt^2...divide both sides by t^2
(2s) / (t^2) = g
H = vt - 5t^2...add 5t^2 to both sides
H + 5t^2 = vt...divide both sides by t
(H + 5t^2) / t = v
The heights (in inches) of 13 plants are 6, 9, 10, 10, 10, 11, 11, 12, 12, 13, 14, 16, and 17. What is the interquartile range o

The given heights:
6, 9, 10, 10, 10, 11, 11, 12, 12, 13, 14, 16, 17.
The first step is to find Median in order to divide the above series into lower and upper quartiles.
To find the median, just cross out the first and the last value until you left with the single value, as the number of elements is odd.
Like first 6 would cancel the last 17,
second number 9 would cancel the second last number 16,
and so on.
By doing above exercise, we are left with 11.
So the median = 11.
Now any number below the median 11 would be in lower quartile series, while other half would be in upper one.
To find the lower quartile, find the median of 6, 9, 10, 10, 10, 11:
Now the numbers are even; therefore, we would do the above-mentioned exercise of cancelling first and the last element until we are left with just 2 elements:
The two elements are: 10, 10.
Take average = (10 + 10) / 2 = 10
So lower quartile = 10
To find the upper quartile, find the median of 12, 12, 13, 14, 16, 17:
Now the numbers are even; therefore, we would do the above-mentioned exercise of cancelling first and the last element until we are left with just 2 elements:
The two elements are: 13, 14.
Take average = (13 + 14) / 2 = 13.5
So Upper quartile = 13.5
The interquartile range = Upper Quartile - Lower Quartile = 13.5 - 10.0 = 3.5
So the correct option is (A) 3.5
