Answer:
Step-by-step explanation:
Given: The probability of brake pads that come off the production line are considered defective. = 0.2
Therefore, the probability that the brake pads are not defective=1-0.2=0.8
The probability that all 200 pads are not defective P(all 200 non defective)=
Then the probability that at least one brake pad is defective in an order of 200 pads
P(at least one defective)=1-P(all 200 non defective)
I saw the image that should have accompanied this problem.
V (-3,-2)
W( 4, 6)
I studied the graph and I can form a right triangle with VW as the hypotenuse.
long leg = 8 units ; short leg = 7 units
Pythagorean theorem
a² + b² = c²
8² + 7² = c²
64 + 49 = c²
113 = c²
√113 = √c²
10.63 = c
the length of stack VW with bar on top is 10.63
Answer:
Step-by-step explanation:
Answer: x=8
Step-by-step explanation:
Since we are given that ∠ABC and ∠DBC are complementary angles, we know that adding them together should give us 90°. We can use this to solve for x.
6x+13+4x-3=90 [combine like terms]
10x+10=90 [subtract both sides by 10]
10x=80 [divide both sides by 10]
x=8
Now, we know that x=8.
