Arranging in ascending order we have
52 55 59 60 62 65 65 66
The median = (60+62)/2 = 61
The mean = 484 / 8 = 60.5
range = 66-52 = 14
interquartile range = 65 - 57 = 8
pairs = 65
Answer:
The bottle contains approximately 0.396258 gallons of water.
Step-by-step explanation:
Answer:
We need a sample size of at least 650
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find the margin of error M as such
In which 
is the standard deviation of the population and n is the size of the sample.
In this problem:
We need a sample of size at least n
n is found when 
So
Rounding up
We need a sample size of at least 650
Simplify: -4a^-(6a-2)+3(a^-1) With the ^ being (2)...
Answer: -a^ -6a -1
The ^ = 2
Answer: n/5 - 10 = 18: this would be the equation. Your answer would be 140.
Step-by-step explanation: Let consider the number as ‘X’
Quotient of a number and 5 can be written as
X divided by 5
Ten subtracted from the quotient of a number and 5 can be written as
(X divided by 5)-10
Ten subtracted from the quotient of a number and 5 is 18 can be written as
(X divided by 5)-10=18
By solving the above equation, find ‘X’
(X divided by 5) = 18 + 10
X/5=28
X = 28 x 5 = 140
