This qn is mistake i think so while addind this 2 eqn the ans is 8x2-6x-4
Answer:
Step-by-step explanation:
candy sold vs money earned
money earned = 2 dollars * number of bars sold- cost of bars
money earned = 2 b -20
this is an equation of a line
(y= 2x-20)
A.The relationship is linear true
B.The relationship is nonlinear false
C.The relationship is always results in a negative profit false
it crosses the x axis at 10 candy bars
D.The relationship always result in a positive profit false
it crosses the x axis at 10 candy bars
E.The relationship is proportional false
F.The relationship is non-proportional true it is a line that does not cross the origin
Answer:
a. The multiplication of these probabilities is justified because the inspections are isolated or don't have the same goal. For instance p1, would mean that not all the planes are checked, p2 that not all the parts in the plane are checked, and p3, that even if the the part where the crack could be inspected, people checking it could not notice it or it could be not identified easily.
b. As the events are independent and there are only two possible answers (detect the plane or not), a binomial distribution could be applied, therefore:
p=0.9*0.8*.5=36 (probability of detecting the crack)
n=3 (number of possibilities, in this case number of planes)
The probability in a binomial formula is given by
Considering that the only possibility that is not being asked is the one of not detecting any crack which would mean x=0, then, we could find the probability as
=1-
Probability is then 0.737856

Answer:
36π cm²
Step-by-step explanation:
The formula of the area of a circle is A=π*r².
Having this, we can find the area of the circle P. The diameter of the circle is 12 cm, so the radius is half of the diameter, so the radius is 6 cm. Then we apply the formula.
