Answer:
<h2>31.25%.</h2>
Step-by-step explanation:
The experimental probability is the ratio between the number of times an event occurs and the total number of trials.
In this case, the total number of trials is 64, because Page roles it 64 times.
Notice that the probability is about one event or the other, that indicates we need to sum both events.
Multiplying by 100, we have a probability of 31.25%.
Therefore, the experimental probability of getting three or four is 31.25%.
I believe it's the first one although I'm not 100% sure tbh
Answer:
You "FOIL" (First, Outer, Inner, Last).
Step-by-step explanation:
You "FOIL" (First, Outer, Inner, Last). Basically, you have to multiple each term by each of the other terms.
(3x+2)(4x-7)
(3x)(4x) + (17)(3x) + (2)(4x) + (2)(-7)
12x^2 - 21x + 8x - 14
12x^2 - 13x - 14
Answer:
Step-by-step explanation:
The given ordered pair is (2,162)(3,486).
Let the equation be
when x=2, y=162
This gives:
Also when x=3, y=486,
Divide the second equation by the first,
When b=3, we have
The exponential equation is:
All these cases represent experiments whose outcomes are all equaly likely. What we mean is that the cards have all the same probability of being dealt (1/52), and all the spaces of the spinner have the same probability of being landed into (1/5).
These probabilities are computed as 1 over all the possible outcomes.
(a) If you want a heart card and a five, you want the 5 of hearts. So, only one card would satisfy your request, and thus you have probability 1/52 of dealing the 5 of hearts.
(b) There are four 10s and four Jacks in the deck, so 8 cards satisfy your request. With probability 8/52, you'll be dealt a Jack or a 10.
(c) You have two "good" outcomes out of 5, so your probability is 2/5.
