Explanation:
The notation means "floor of x". Whatever decimal value x is, we just ignore the decimal portion and just focus on the integer part. We round down to the nearest whole number. We always round down.
For something like x = 2.5 or x = 2.7, the value of will be 2. It doesn't matter that 2.7 is closer to 3 than it is to 2. The interval
will be entirely on the x axis since we are taking the result of the flooring operation and subtracting off 2. Notice how x = 3 is not included. This is because x = 3 leads to y = 1 instead of y = 0. So we have an open hole at the end of the interval. The same goes for any other piece as well.
Answer:
0.8213
Step-by-step explanation:
-This is a binomial probability problem given by the function:
Given that n=21 and p=0.2, the probability that she experience a delay on at least 3 days is calculated as:
Hence, the probability that she experience delay on at least 3 days is 0.8213
Answer:
Step-by-step explanation:
The symbol is set notation for UNION--put two sets together into one set.
The first part of the interval notation describes x less than or equal to -5 -- notice the bracket symbol after -5, meaning include -5.

Answer:
62°
Step-by-step explanation:
Since one arm making angle x is diameter. So, by inscribed angle theorem, we have:
Answer:
The correct option is C
Step-by-step explanation:
From the question we are told that
The number of independent variables is
The number of observation is
Since n is are independent variables then their degree of freedom is 3
The denominator(i.e z) degrees of freedom is evaluated as
So for the numerator (n) the degree of freedom is Df(n) = 3
So for the denominator(i.e z) the degree of freedom is Df(z) = 43
