I would assume that they want a cosine value that would give the same answer. sin(30°) is equal to 1/2
Therefore cos(×) = 1/2
x = arccos(1/2)
x=60
cos(60°)
Answer:
B) There tends to be a linear association between variables
c) the data includes one or more outliers
Answer:
28 strokes
Step-by-step explanation:
The computation is shown below:
It is given that the 42 strokes are required to fill up the 3 by 5th
So for completing the line, the number of additional strokes required is
But before the total strokes required is
= 42 × 5 ÷ 3
= 70
This represent the total
so, the additional strokes is
= 70 - 42
= 28 strokes
Answer: FG = 3x + 10
<u>Step-by-step explanation:</u>
EF + FG = EG <em>Segment Addition Postulate</em>
x-7 + FG = 4x+3 <em>Substitution</em>
-7 + FG = 3x + 3 <em>Subtraction Property of Equality</em>
FG = 3x + 10 <em>Addition Property of Equality</em>
It's obvious that the segment A'B' is symmetrical to AB about the axis of symmetry that is the x-axis, ten it's x=0
