Answer:
tanx + cotx = 
Step-by-step explanation:
<u><em>Explanation</em></u>
Take R.H.S =
= 
= 
= 
= tanx + cotx
tanx + cotx =
Step-by-step explanation:
First, we should define supplementary angles.
Supplementary angles are angles that add up to 180 degrees.
Since 1 and 2 are supplementary and we know their values, we just set them equal to 180 degrees
(
4
y
+
7
)
+
(
9
y
+
4
)
=
180
Now just solve for one variable
13
y
+
11
=
180
13
y
=
169
y
=
13
Now the question asks for m<2, which is
9
y
+
4
So we just plug in
9
⋅
13
+
4
=
121
So m<2 is 121
Using it's concept, it is found that the sample mean package weight for Thursday is of 19 ounces.
<h3>What is the mean of a data-set?</h3>
The mean of a data-set is given by the <u>sum of the observations divided by the number of observations</u>.
For Thursday, the package weights in ounces are given by: {18, 19, 20, 19}.
Hence, the sample mean in ounces is of:
M = (18 + 19 + 20 + 19)/4 = 19.
