Pretty sure its 183. correct me if im wrong tho
First, we get the standard error of the mean using
σm = σ / √N
= 5 / √100
= 0.5
Next, we subtract and add 1.96 standard deviations from the mean (since the confidence interval is 95%). So,
8 ±1.96 (0.5)
= 8 <span>± 0.98
The answer is
</span>E) 8±0.98
G(x)=(x+3)2 we must find x? so x+3=0 x=-3 we transformation -3 on left
Answer:
x = 62
Step-by-step explanation:
Since 2 sides are congruent then the triangle is isosceles.
Thus the 2 base angles are congruent.
The sum of the 3 angles = 180°
x =
=
= 62
