X = 18 for this one.............
This is fairly easy, all you need to do is write the ordered pairs for each graph, for these there are 5 ordered pairs for both.
In order to create the ordered pair all you need is this 'formula' of (x, y)
In the first graph 'input' would be the x value and output is the y value. So all you do is plug them into the formula.
(-10,-20)
(-5,-10)
(0,0)
(5,10)
(10,20)
Those are all the ordered pairs for graph A. Now just do the same thing for graph B.
Answer:
probability of getting no heads: 1/ 8
probability of at least two tails: 1/4
Step-by-step explanation:
To calculate the probability of getting no heads, multiply the probability of not getting heads for each coin. A coin has two sides: heads and tails; the probability of not getting heads would be 1/2.
1. Multiply the probabilities for each coin
1/2 · 1/2 · 1/2 = 1/8
To calculate the probability of getting at least two tails, multiply the probability of getting tails for two coins and the probability of flipping either heads or tails for the remaining coin. Because it is at least two tails, the remaining coin can flip to either heads or tails.
1. Multiply the probabilities for each coin
1/2 · 1/2 · 2/2 = 1/4
I would go with 12.5
I’m more of an English person but that’s my best guess.
3/24
1/8
1 divided by 8
=12.5
Hope you get it right :)
