Answer:
None of the options is correct
Step-by-step explanation:
It is important to know that he expression a < x < b means that x is greater than a and less than b. So, for finding the correct value let's analyse each option.
A. 4 < 50 < 5
50 is greater than 4 but it is not less than 5, so, option A is incorrect.
B. 7 < 50 < 8
50 is greater than 7 but it is not less than 8, so, option B is incorrect.
C. 8 < 50 < 9
50 is greater than 8 but it is not less than 9, so, option C is incorrect.
D. 10 < 50 < 11
50 is greater than 10 but it is not less than 11, so, option D is incorrect.
Thus, none of the options is correct.
Explanation:
Since we have given that
The prices of three t-shirts styles i.e $24, $30, $36 with their probability is given by
As we know that,
Now,
and
So,
So, the expected value of a t-shirt = $31.
Answer:
true
Step-by-step explanation:
because the expression shown is a monomial we simply add the degrees of each term
4 + 2 + 3 = 9
5x4y2z3 indeed has a degree of 9
Note: if the terms were being added we take the highest degree and that is the degree of the expression.
ex. 5x^4 + y^2 + z^3 would have a degree of 4
