Answer: i think its true
Step-by-step explanation:
The probability of not picking a red marble is 0.2.
The probability of picking a yellow or green marble is 0.5
The probability of drawing an even number of a number greater than 4 is 1.
The probability of getting heads and an even number is 1.
The probability of drawing a 2 or a 4 is 0.25.
<h3>
What are the probabilities?</h3>
Probability determines how likely it is for an event to happen. The chances of the event occurring lies between 1 and 0.
The probability of not picking a red marble = (number of all the marbles - red marbles) / total marbles
4/20 = 0.2
The probability of picking a yellow or green marble = (number of yellow marbles / total number of marbles) + (number of green marbles / total number of marbles)
2/20 + 8/20 = 10/20 = 0.5
The probability of drawing an even number of a number greater than 4 = (number of even numbers / total numbers) + (numbers greater than 4 / total numbers)
5/10 + 5/10 = 1
The probability of getting heads and an even number is = (side that is head / total sides) x (even numbers on a die / total numbers on a die)
1/2 x 3/6 = 1
The probability of drawing a 2 or a 4 = 1/8 + 1/8 = 2/8 = 0.25

Answer:
D
Step-by-step explanation:
The standard form for a parabola is ax^2+bx+c. In this equation, b=0 and c=0. For g(x), you would plug in your y-value that was given (which is 4) and you would plug in your x-value that that given (which is 1). Use PEMDAS. The correct answer is the one that is true.
A. g(x) = (4x)^2
4 = (4(1))^2
4 = 16. (not true)
B. g(x) = 1/4 x^2
4 = 1/4 (1)^2
4 = 1/4 (not true)
C. g(x) = 16x^2
4 = 16(1)^2
4 = 16 (not true)
D. g(x) = 4x^2
4 = 4(1)^2
4 = 4. (true --> correct answer)
This is slope-intercept form y=mx+b
when you substitute it, it becomes y=6x-3
