Answer: 84
Explanation:
Total for 5 tests = 80 x 5 = 400
Total for 4 tests = 84 + 75 + 81 + 76 = 316
5th score = 400 - 316 = 84
Since angle C is not 90 degrees, it's one of the acute angles
in the right triangle.
(The side adjacent to angle C ) divided by (hypotenuse)
is the cosine of angle C .
(adjacent) / (10 inches) = cos(40 degrees)
Multiply each side by (10 inches):
Adjacent side = (10 inches) x cos(40) =
(10 inches) x 0.766 =
7.66 inches (rounded)
It is given that probability of a student being on the debate team is 0.42
So, P(D) = 0.42
It is given that probability of a student being on the math team is 0.26
So, P(M)= 0.26
The probability that he is on both teams is .20
So,
We have to determine the probability his is on the math team if we know he is on the debate team. This is the case of conditional probability.
So,
= 0.476
= 0.48
Therefore, the probability that he is on the math team if we know he is on the debate team is 0.48.
Option 1 is the correct answer.
If the three slashes are 190, 195, and 200, we can see it as
<span>-l----------l--------|--l- with the slightly longer line being around 198.78. Since it is clearly closer to the end of the line than the start of the line, we round it to 200</span>
