Answer: D
Step-by-step explanation:
The number generator is not fair, in most of the experiments, considerably less than 60 % of the selected marbles are green.
And if Sixty percent of the marbles in the jar are green. A number generator should simulates randomly by selecting atleast one of the 60% of green marbles from the jar
Equation of a parabola with vertex at (2, -1) is
y = a(x - 2)^2 - 1
Using the given point: -3 = a(4 - 2)^2 - 1
-2 = a(2)^2
4a = -2
a = -1/2
Therefore, required equation is
y = -1/2(x - 2)^2 - 1
y = -1/2(x^2 - 4x + 4) - 1
y = -1/2x^2 + 2x - 2 - 1
y = -1/2x^2 + 2x - 3
Answer:
Add 4 positive unit tiles to each side.
Step-by-step explanation:
The original equation is:
3x - 4 = 2x + 5
After adding 4 positive unit tiles to each side, we get:
3x - 4 + 4 = 2x + 5 + 4
3x = 2x + 9
which simplifies the original equation, because at the beginning there were independent terms at both sides of the equal sign and now all independent terms are on the right side (the +9 term). Notice that the other options don't give this result.
Answer:
x=3.01667

Answer:
B. 1/8
Step-by-step explanation:
Chance of each number = 1
Total number of chances = 8 (including 0)
Therefore,
Chance that each number will occur = 1/8
Hope it helps:)
Have a good day!
