Given that the steps are not shown, I am going to show you all the rigtht steps in detail and so you will be able to compare and tell which step from you list contains an error:
1) Traslation into algebraic language:
<span>“three less than the quotient of a number squared and nine, increased by eight”
3 - (n^2) / 9
2) Evaluate it when n = 6 (replace the value of n)
3 - (3^2) / 9
3) solve the parenthesis
3 - 9/9
4) divide 9/9
3 - 1
5) Subtract
2
</span>
Now you know all the steps and can tell which of the steps on the list is wrong.
1. B
2. A
3. A
All of theses are true
Answer:
A) (0,5)
Step-by-step explanation:
Coordinate point (0,5) lies within the bounded blue region
<span>Answer:
The two events are independent. In the given scenario, P(M and N) =0.25
Explanation:
1) Independent events are those that do not affect each other. In this case the number that you roll does not change the flip of the coin. So, whatever number you get with the die, the probabilities of landing tail or head when tossing the coin are the same.
2) The probability of the two simultaneous events: getting an odd number and landing a tail, since they are independent, is equal to the product of the two independent events:
P(M and N) = P(M) x P (N) (only because they are independent)
3) The probability of getting and odd number is 0.5 (half of the numbers are odd and half are even => probability = 1/2)
4) The probability of the coin lands tail is 0.5 (1/2).
5) Then the joint probability is 0.5 x 0.5 = 0.25</span>
