Answer:
Step-by-step explanation:
6) taking 45 degrees as the reference angle,
the adjacent side is √6
The opposite side is x
The hypotenuse is y
Therefore, we would apply trigonometric ratio.
Tan # = opposite side / adjacent side
Tan 45 = x/√6
1 = x/√6
x = 1 × √6 = √6
Cos # = adjacent side/hypotenuse
Cos 45 = √6/y
Cos 45 expressed in surd form is √2/2. Therefore,
√2/2 = √6/y
y √2 = 2√6
y = (2√6)/√2
Answer:
<h2>
Most explained:</h2>
40% = 100%
15 = (100% - 15% = 85%) 85% in Alaska
California = 15% of 40 = (0.15 x 40) = 6
Alaska = 85% of 40 = (0.85 x 40) = 34
<h2>The simple way (or the way i found it simple):</h2>
<h3>40 - 15 = 34</h3><h3>15% of 40 = 6</h3>
<h3>(I found the simple way after i solve the first way)</h3>
Bye, i hope this helps.

Answer:
Step-by-step explanation:
Given that The data to represent average test scores for a class of 16 students includes an outlier value of 78.
We can find sum of all 16 test scores = 84(16) = 1344
Outlier found = 78
If outlier is removed new sum = 1344-78 = 1266
Number of entries without outlier = 15
New average = 1266/12 =84.4
We find that average of new data increases.
Also whenever we remove outlier std deviation also would be reduced.
Please, see the offered solution, note, there are 2 ways in it (a and b)
86-25.2 = 60.8 pounds of flour used
60.8/10 = 6.08 pounds used per day
