Since 10 out of 14 marbles are green, the probability of selecting a green marble is 10/14=0.714.
Similarly, the probability of selecting a red marble would be 4/14.
Answer: 0.714
First of all move all the Xs to the left side, and the numbers to the left.
So
x/2-x = -13
Which means
X/2-x/1 = -13
Which means x/2-2x/2 = -13
So u combine to two fractions
-x/2 = -13
-x = -13 * 2
Which means x = 26 (u flip the negativity)

Answer: 4</h3>
==========================================================
Rule:
If A+B = 90, then tan(A) = 1/( tan(B) ) and tan(B) = 1/( tan(A) )
-------
Since C = 90, this must mean the other two angles A and B are acute and complementary. So A+B = 90 must be the case. This allows us to use that rule above.
So,
tan(B) = 1/( tan(A) )
tan(B) = 1/( 0.25 )
tan(B) = 4
-------
Here's another way to think about it.
If tan(A) = 0.25, then we could have BC = 1 and AC = 4 as the opposite and adjacent sides respectively. That leads to tan(A) = opposite/adjacent = BC/AC = 1/4 = 0.25
When computing tan(B), the BC and AC sides swap roles in terms of opposite and adjacent,
tan(B) = opposite/adjacent = AC/BC = 4/1 = 4.
For any of these cases, we don't involve the hypotenuse AB.

Answer:
B. The domain for f(x) is the set {-2, -1, 0, 1, 2, 3, 4, 5, 6}
D. f(-1) = 6
Step-by-step explanation:
The question gives a table marking the different coordinate pairs for a function, where f(x) is y. The top row represents the x-values and the bottom row represents the y-values.
Domain
The domain of a function is the set of x-values that the graph covers. In this case, the x-values are all integers between -2 and 6. We can see this in the top row of the table. Answer choice B best represents this domain.
Solving for F(x)
F(x) represents a specific y-value, for example, f(-1) represents the y-value when x = -1. So, to test choice D, we need to find what y-value matches -1 on the table. The table shows that when x = -1, f(x) = 6. This means that answer choice D must be correct.
