I am not 100 percent sure but i think you multiply and the answer is 7.75 if not then try to divid how you get 7.75 is you make 3/4 into a decimal and that becomes 0.75 them multiply by 10 and get 7.75
Answer: 11 in.
Step-by-step explanation:
Given
The volume of the cylindrical vase is 
Inside diameter is 
Suppose, h is the height of the vase
Volume is given by
Insert the values
Thus, the height of the vase is 
Step-by-step answer:
assuming the true-false test have equal probabilities (each 0.5), we can use the binomial probability to calculate the sum of probabilities of getting 10, 11 or 12 questions correctly out of 12.
p=probability of success = 0.5
N=number of questions
x = number of correct answers
then
P(x) = C(N,x)(p^x)((1-p)^(N-x))
where C(N,x) = N!/(x!(N-x)!) = number of combinations of taking x objects out of N.
P(10) = C(12,10)(0.5^10)((1-0.5)^2) = 33/2048 = 0.01611
P(11) = C(12,11)(0.5^11)((1-0.5)^1) = 3/1024 = 0.00293
P(12) = C(12,12)(0.5^12)((1-0.5)^0) = 1/4096 = 0.00024
for a total probability of 79/4096 = 0.01929
Answer:
no of science teachers is 20
