Answer:
False.
Step-by-step explanation:
A cylinder can be defined as a three-dimensional figure or solid shape that comprises two (2) parallel bases that are joined together by a curved surface.
Also, the surface area of a cylinder refers to the total space which is occupied by its two flat surfaces (base) and the curved surface.
Mathematically, the formula for finding the surface area of a cylinder is;
S.A = 2πrh + 2πr²
Where;
S.A is the surface area of a cylinder.
r is the radius of a cylinder.
h is the height of a cylinder.
Answer: 20 students each year
Step-by-step explanation:
60+20= 80
80-60=20
you can do 80 minus 60 and get 20
then to double check you can add 60 and 20
28% is 28/100 as a fraction but the simplest form is 14/50 and it can be simplified to 7/25. the decimal is 0.28
fraction is 7/25
decimal is 0.28
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
44 you should subtract 80 and 36 then the answer will be 44
