Answer:
The correct option is D
Step-by-step explanation:
To find the solution of this problem firstly we will find the probability that some one is in the brass section and play trombone.
We will multiply the probability that a member is in the brass section which is 0.50 with the probability that a member plays trombone, given that he or she is in the brass section which is 0.36
= 0.50 * 0.36
=0.18
Therefore the probability that a randomly selected band member is in the brass section and plays trumpet is 0.18
Thus the correct option is D....
1-make the demonitores the same
2-remove digits next to (x)
3-solve manually
Step-by-step explanation:
use microsoft maths
Total time = upstream time + downstream time
he rowed the same distance both ways.
upstream time = D/4
downstream time = D/6
total time = D/4 + D/6 = 3D/12 + 2D/12 = 5D/12 = 3 hours
D = 3*12/5 = 36/5 or 7.2 miles
where D is the one-way distance. The total distance he rowed is 2*D = 72/5 or 14.4 miles
Known :
w = 12 feet
h = 18 feet
V = 3.240 feet³
Asked :
l = ...?
Answer :
V = l × w × h
3240 = l × 12 × 18
3240 = 216 l
l = 3240 ÷ 216
l = <u>1</u><u>5</u><u> </u><u>feet</u>
So, the length is 15 feet
