Answer:
4/7
Step-by-step explanation:
Probability is the likelihood or chance that an event will occur.
Probability = Expected outcome/Total outcome
Given
Total outcome = 2blue ties+1red tie+2blue coats+2orange coats
Total outcome = 7
If he wears a blue tie, then the expected outcome will be 2.
Probability that he wears blue tie = 2/7
If he wears a blue coat, then the expected outcome will be 2.
Probability that he wears blue coat = 2/7.
The probability that he wears either a blue tie or a blue coat will be 2/7+2/7 = 4/7
Answer:
the answer is X=-8 or X= 2
Step-by-step explanation:
subtract 10 from both sides in order to eliminate 10.
x^2 + 6x -16
find two factors of -16 that sum up to 6.
-2 and 8 are two factors of -16 that sum up to 6.
(x-2)(x+8)
x-2= 0, x= 2
x+8= 0, x = -8
Step-by-step explanation:
2x (5x - 1) + (3x^2 - 7x - 2)
= 10x^2 - 2x + 3x^2 - 7x - 2
= 13x^2 - 9x - 2
a = 13
b = -9
c = 2
A function is defined as a mathematical graphical equation, that states that for every value of X there must be one and only one value of y.
For instance the coordinates :
(2,3) and (2,4) do not represent a function, because in both cases the X value is the same and not unique for the points.
