Question 8 of 14 A factory makes lightbulbs. The probability that a bulb is defective is g. If 500
lightbulbs are tested, about how many are expected to be defective?
A. 63
B. 50
C. 437
D. 8

the answer is 1030 it's very simple math.

d

because parallelagram have all 4 angels the same size dependeing and a rectangle and square are oth parallelogram

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
