Answer:
the awnser is A
Step-by-step explanation:
There are four values, including the unknown value x. The sum of the four values is the given value of the mean, 11.5, multiplied by four. Let S be the sum of the four values. Then we can write:


x = 46 + 5 = 51
The answer is: The value of x is 51.
Area=height times base (for some prisms including cylinders)
vcylinder=hpir²
h=height
therefor pir²=base area
vcylinder=height times aeraofbase
given
h=9
v=324pi
324pi=9(basearea)
divide both sides by 9
36pi=areabase
the area of the base is 36pi square cm (put 36 in the blank since the pi is already there)

Step-by-step explanation:
Given : The proportion of all students at a large university are absent on Mondays. : 
Sample size : 
Mean : 
Standard deviation = 

Let x be a binomial variable.
Using the standard normal distribution table ,
(1)
Z score fro normal distribution:-

For x=4

For x=3

Then , from (1)
Hence, the probability that four students are absent =
