Answer:
The chances Gavis get four or more correct problems is 8/11 or 72.72%
Step-by-step explanation:
The exam is composed of 6 problems out of 12 possible cases (Pc=12). There are 2 groups of problems:
The 8 problems that Gavin has the answer (Problems A).
The 4 problems that Gavin hasn´t the answer (problems B).
Therefore:
P(A≥4)= P(A=4) ∪ P(A=5) ∪ P(A=6) = P(A=4) + P(A=5) + P(A=6)
Before we start analyzing the problem, we have to understand that problems in the exam are selected at random, but a problem can´t be selected twice. therefore picking a specific problem will reduce the pool of that specific group and of the total number of available problems.
If we call to the probability of an answer of the X group to be the i° picked problem from the j° picked problem of that group:
with the total number of problems in that group.
We analyze now 3 different problems:
For P(A=4) we can take the solution from P(A=5) and say that:
where "c" is the combinatorial of 2 problems B with 4 problems A. In this case "c" is 15, therefore:
The width is 18 because if you take 82 and subtract 10 for the 2 lengths ( because we are using perimeter) you come out with 72. 72 divided by 4 is 18, the lengths are five more because we took away that 5 in the beginning.
W=18cm
L=23cm
Answer:
D- 38,430
Step-by-step explanation:
To find 18% of 213.5k, we need to convert 18% back into its decimal form (0.18), then multiply it by 213.5k and boom! there is your answer.
Answer:
Carl statement is correct
Step-by-step explanation:
Absolute value is the value of the number without considering the sign of the number.
Absolute value of two integer can be same
example absolute value of -3 and 3
absolute value of |-3| = 3
absolute value of | 3 | = 3
hence, two integer have same absolute value.
so, Carl statement is correct about the absolute value.
