Just combine like terms! So x^3 and 1^3!
We need to find the probability of the event:
having blue eyes or blond hair
This event is the union of the events:
A: having blue eyes.
B: having blond hair.
So, we need to find the probability P(A ∪ B). In order to do so, we can use the following formula:
P(A ∪ B) = P(A) + P(B) - P(A ∩ B)
We know that the probability of the intersection of A and B (having both) is
P(A ∩ B) = 24%
Also:
P(A) = 43%
P(B) = 46%
Then, using those values into the above formula, we find:
P(A ∪ B) = P(A) + P(B) - P(A ∩ B)
P(A ∪ B) = 43% + 46% - 24%
P(A ∪ B) = (43 + 46 - 24)%
P(A ∪ B) = 65%
Answer:
Answer C
Step-by-step explanation:
If the polygon has n sides, then the number of diagonals the polygon has is
(n - 3)*n/2
So for a seven sided figure the number of diagonals would be
(7 - 3)(7)/2 = 4*7/2 = 28/2 = 14
Answer:
seirously I don't know if that's an "x" or a multiplication sign
Step-by-step explanation:
[3² x(189/9)]-32
9. 21x - 32
189x - 32
x = 189/32
x = 5.29/32
[3² x(189/9)]-32
9x21-32
189-32
157
1/5 of 2 liters...." of " means multiply
1/5 * 2/1 = 2/5 liters <==
