Answer: Margin of Error for the given CI is 0.08
Step-by-step explanation:
Given the data in the question;
it is a symmetric class interval hence, sample proportion p = (0.50 + 0.66) / 2
p = 1.16 / 2
sample proportion p = 0.58
Margin of Error E will be;
E = 1/2 × length of Confidence interval
Margin of Error E = 1/2 × ( 0.66 - 0.5)
Margin of Error E = 1/2 × 0.16
Margin of Error E = 0.08
Therefore; Margin of Error for the given CI is 0.08
Answer:
To find the product, we use FOIL method.
First terms
Outer terms
Inner terms
Last terms
Product = (7x * 8x) + (7x * 5) + (-4 * 8x) + (-4 * 5) =
Product = 56x2 + 35x - 32x - 20 =
Product = 56x2 + 3x - 20

Answer:
(0,4)
Step-by-step explanation:
The line AD is a median, because D is the midpoint of BC.
The centroid is the point of intersection of three medians of triangle, we don't need to depict any another median, because we know that centroid divide each median in ratio 2:1 from the vertices of a triangle from which a median was depicted. That's obvious that the median AD was depicted from A. Let the point of centroid be M. AM:MD is 2:1. So we should find the coordinates of D
xD= (xa*1+xd*2)/ (2+1)= ((-4)*1+2*2)/3=0
yd= (ya*1+yd*2)/ (2+1)= (2*1+ 5*2)/3=12/3=4
(0,4)
