Here’s a picture of my work. The answer is seven. Hope this helps :-)
<h3>
Answer: H. 33</h3>
=============================================
Work Shown:
Solve 5m^2 = 45 for m to get
5m^2 = 45
m^2 = 45/5
m^2 = 9
m = sqrt(9)
m = 3
I'm making m to be positive so that way the expression 12m is not negative. Otherwise, sqrt(12m) would not be a real number result.
--------------
Plug m = 3 into the expression we want to evaluate
m^3 + sqrt(12m)
3^3 + sqrt(12*3)
27 + sqrt(36)
27 + 6
33
we are given with two dice and that we are asked in the problem to find the probability of the following:
a. sum at least 4b. sum at least 6
THe sample space of this problem is
{11, 12, 13, 14, 15, 16, 21,22, 23,24,25,26,31,32,33,34,35,36,41,42,43,44,45,46,51,52,53,54,55,56,61,62,63,64,65,66} a total of 36.a. 33/36 = 11/12b.11/36
Answer:
4) "Everyone in Spain speaks at most 9 languages."
Step-by-step explanation:
A negation is a statement that contradicts the original statement. Since the original statement regards people in Spain, options 2, 5, 6 and 7 can be ruled out as they refer to speakers outside of Spain.
Evaluating the remaining statements.
1) "Everyone in Spain speaks at least 10 languages."
If that is true, then someone in Spain speaks at least 10 languages, it doesn't negate the original statement.
3) "There is someone in Spain who speaks at most 9 languages."
It only refers to one specific individual, it doesn't negate the original statement.
4) "Everyone in Spain speaks at most 9 languages."
This means that nobody in Spain speaks more than 9 languages, contradicting the original statement.
The answer is statement 4.
