Answer:
40.7 pounds
Explanation:
Given that:
Mean, m = 40
Standard deviation, σ = 1.3
Weight greater than 30% = 0.3
P(x > Z) = 0.3
Z = (x - m) / σ
P(x > Z) = 0.3
Z = 0.524 ( Z probability calculator)
Hence,
0.524 = (x - 40) / 1.3
0.524 * 1.3 = x - 40
0.6812 = x - 40
x = 0.6812 + 40
x = 40.6812
x = 40.7
Hence, Marlon weighs about 40.7
Answer: 3/8 of the class went to the evening session.
Explanation:
So it says on Sunday 3/4 of an 8th grade class went to see the movie.But we do not know the real population of the 8th grade class. But is says that out of the 3/4 of the students that went to the movie have of them went in the afternoon so we will multiply 1/2 by 3/4 to find out how many people went to the afternoon session.
3/4 * 1/2 = 3/8 So we know that 3/8 of the 3/4 of the class went in the afternoon so we will now subtract 3/8 from 3/4 to find out what fraction went in the evening.
=
To think about it if half of the 3/4 of the class went in the afternoon then another have will go in the evening.
