Answer:
Step-by-step explanation:
the median is the middle number....but first u have to put the numbers in order from least to greatest
56,56,58,60,65.....and the median (the middle number) = 58 <==
and just so you know...it is easy to find the middle number when there is an odd number of numbers...but when there is an even number of numbers, there will be 2 middle numbers.....so then u add the two middle numbers and divide by 2 to get the median
X + y = 24
x - y = 2
-------------add
2x = 26
x = 26/2
x = 13
x - y = 2
13 - y = 2
-y = 2 - 13
-y = - 11
y = 11
ur numbers are 11 and 13
9. You need an exact answer. So I will give you it but I'll also give you an approximation because it might help you understand it more.
Because we know the cosine fo theta, we can evaluate the inverse cosine of -2/3 first to find theta.
= 131.81° approx.
Because 131.81° is in the second quadrant its third quadrant partner is 228.19°. Which would make the sine 0.75 approximately.
But we need an exact answer I suppose so which is this disgusting mess.... I know it looks scary but it is basically all the steps we just did but without evaluating anything.
This can be simplified using: sin(x− y) = sinxcosy−cosxsiny
To...
answer:
10. Okay. So because we have a point we can say that...
θ =
sin(θ) = +sin()
11. arcsin(-0.37) = = -21.72°+2kπ or 201.72°+2kπ approx. where k has to be an integer
answer: idk if you want one or more solutions so I gave you them all.
12. arccos(-√3/2) =
Remember that "k" must be an integer.
answer: 5π/6
120 seconds
1 min = 60 seconds
Since the angle they have to equal is 97 the answer is 12
