b=0.2
I believe this is right. But not 100%
Answer:
The largest integer is 29.
Step-by-step explanation:
Let the consecutive positive integers are x, x+1 and x+2.
The square of sum of squares of three consecutive positive integers is 2354 such that,

It is a quadratic equation whose solution is given by :
x = 27 and x = -29
First positive integer = 27
Second positive integer = 27+1 = 28
Third positive integer = 27+2 = 29
Hence, the largest integer is 29.
The formula for the Binomial Theorem with a power 6 is as:

Thus, if we plug in 20 for x and 5 for y, our first term itself will be
which is much greater than 256 and thus it will not make any sense to use
to approximate 256 using the binomial theorem.
Also, it will not make any sense to use
as that has no power and we know that Binomial Theorem makes use of Power. Anyway,
.
Our best bet here would be to use the equation with power 8:

and have
and
which will give us

Answer:
50%
Step-by-step explanation:
Recall : When given a normal or Symmetric distribution, the mean of the distribution is at the centre with 0.5 or 50% of the distribution to either side (right and left) of the distribution.
Hence, if the mean = 21 ; then the percentage of student body with atleast 21 years is the percentage to the left of the distribution, which is 50%.
Therefore, P(x ≤ 21) = 0.5 = 50%
