Answer:
the probability of choosing more than 3 non defective units out of a sample of 4 is 0.784 ( or 78.4%)
Step-by-step explanation:
Assuming that all the microwaves come from shipments selected at random, such that the probability of each microwave to be defective is independent from the others, then the random variable X= number of microwave units that are defective , has a binomial distribution such that the probability distribution is
P(X) = n!/[(n-x)!*x!]*p^x*(1-p)^(n-x)
where
n= number of microwaves bought=4
x= number of microwaves that are defective
p= probability that a microwave has defective units = 2/9
then the probability that the restaurant buys at least 3 nondefective units is
Pfinal = P(X≤1)=P(X=1)+P(X=0) = 0.418 + 0.366 = 0.784
Answer:
264 cm^2.
Step-by-step explanation:
The area = 1/2 * height * sum of the parallel sides
= 1/2 * 12 * (28 + 16)
= 6 * 44
= 264 cm^2.
Answer:
rectangle A:
LENGTH:9
WİDTH:6
rectangle B:
LENGTH:9
WİDTH:3
Step-by-step explanation:
if you want to find the length of a square you should know that in a square all 4 sides lengths are the same so the are is give as 36 to find 1 side of the length we have to divide 36 with 4(because there are 4 sides)
which means the lengths of each side is 9.
it is the same as in rectangle a and b length hasn't changed only the width has changed.
we can also find the width with the information given us about its ratio.
it says that The ratio of area A to area B is 2:1
the length is 9:
we can make it simple like this lets say 2x and 1x has to give us 9
so we can say 3x=9,x=3
to find the width we can say that 2x width is for rectangle A and 1 x is rectangle B. so x was 3:
2x=6
1x=3
these are the widths of rectangle A and B
