Answer: It's is B
Step-by-step explanation:
Answer:
The probability of getting two heads on two coin tosses is 0.5 x 0.5 or 0.25.
(The probability of getting heads on the toss of a coin is 0.5)
Step-by-step explanation:
The Product Rule is evident from the visual representation of all possible outcomes of tossing two coins.
Answer:
3x +y -18 = 0
Step-by-step explanation:
The equation of the perpendicular line can be formed from the given equation by swapping the x- and y-coefficients, and negating one of them. The constant in the new equation will be the constant necessary to make the line pass through the given point.
__
<h3>swapped coefficients</h3>
3x +y +c = 0 . . . . . now both coefficients are positive
<h3>new constant</h3>
We want c such that the equation is satisfied at the point (x, y) = (9, -9):
3(9) +(-9) +c = 0
27 -9 +c = 0
c = -18
<h3>equation of perpendicular line</h3>
The equation of the desired line is ...
3x +y -18 = 0
Answer:
y=7.2 should be the answer
