Answer:

Step-by-step explanation:

cos(x) = -.6 means that you are looking for the angle, x, that has a cosine of -.6.  If you do this on your calculator, you press the 2nd button, then cos (in degree mode, NOT radian mode!) and then -.6 and enter.  You get an angle measure of 53.13010235°.  If that angle is complementary to angle y, then angle x and y added together have to equal 90°.  Therefore,

90 - 53.13010235 = 36.86989765°

Take the sin of this angle by hitting sin and then entering in the 36.86989765.  This gives you a value of .6000000000001 which, for all intents and purposes, is .6

What are the 1st and 3rd quartiles?<br> what is the interquartile range?
FrozenT [24]

Answer:

The first quartile is 5

The third is 8

The interquartile is the difference between the first and third quartile.

The interquartile is 3

Step-by-step explanation:

First, make a list of all the numbers. To find the first quartile, you have to first find the median. The median is the first 7 in the list.

Everything before 7 is the lower percentile of the range.

The firsr quartile is the median of the lower percentile.

The lower list is:

2,3,4,4,5,6,6,6

The median of this list is 5.

The process for finding the third quartile is the same except the list is the higher percentile which is the list of numbers above the median.
