Answer:
b
Step-by-step explanation:
330 divided by 30 equals 11
The total number of students is 45 + 48 +40 = 133 students
1/2 * 133 ------ 3/4 * 133
(66.5 ; 99.75)
So we can say that b<span>etween 65 and 100 students packed their lunch</span>
The probability that a student will fail is 3/25, there are 25 of them, thus the sample space is 25 and 3 out of that is 3/25 or 0.12.
what's the probability that one will pass? well, the opposite of failing, thus is the complement of 0.12, namely, 1 - 0.12.
Using the discrete distribution, it is found that the probability that it offers an even number of honors classes is of 0.68.
<h3>What is the discrete probability distribution?</h3>
The distribution for the number of honors classes the school offers is given by:
Hence the probability of an even number is given by:
P(even) = P(X = 0) + P(X = 2) + P(X = 4) = 0.38 + 0.25 + 0.05 = 0.68.

Answer:
x=125º
2x=250º
Step-by-step explanation:
720 is the sum of the interior angles of a Hexagon
720=60+65+120+100+3x
720=345 +3x
-3x=345-720
-3x=-375
-x=-125
x=125
