Y - y₁ = m(x -x₁)
slope m = -0.8, from point (14.5, 12.8) , x₁ = 14.5, y₁ = 12.8
y - y₁ = m(x -x<span>₁)
</span>y - 12.8 = -0.8(x - 14.5<span>)
</span>
<span>Option B </span>
Answer: 46
Step-by-step explanation:
Given : Margin of error : E= 17
Standard deviation : 
Critical value for 90% confidence level :
Formula to find sample size is given by :-
i.e. 
Hence, the required minimum sample size = 46.
To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.
I believe it's half the radius of the circle because the side would equal the radius and the compass is in the middle of the side, right?
