Step-by-step explanation:
sin^-1 (21/67) = 18.27 degrees
√(67)^2 - (21)^2 = 63.62

Common difference (d) = - 14-(-17)
d = -14+17
d = 3...
Tn = -17+(n-1)3
Tn = - 17+3(n-1)
Option a is correct.....
Answer:
Step-by-step explanation:
First off, let's change everything to a common denominator. This will allow us to add the fractions!
To find a common denominator, we find a number that both 4, 28, and 1 can go into. 28 is the best choice, as 4 goes into it 7 times, 28 goes into it once, and 1 goes into it 28 times.
Let's change the first fraction into a number with a denominator of 28!
= 1. Multiplying a number by one doesn't change its value.
The second fraction, 
, already has a denominator of 28, so we don't have to do anything with it.
Now to the third number, -1:
Now, let's add them all up!
One last step, to simplify:
<h2>Your answer is 1/14!</h2>
Answer:
119
explained: you would have to take all the numbers and line them from greatest to smallest, for example 100,103,103,105,106,112,115,106,112,115,117,121,122,122,128,129,141,141,141
and since your median is your middle number, and you have an even set of numbers that means you will have two medians 117 and 121. You add them up and divide by two which equals 119.
Hope this helps!
