Answer:
0.00397
Step-by-step explanation:
I am taking a guess. Like I saw this example (5/9)(4/8)(3/7)(2/6)=120/3024=0.0397
Or (5C4)/(9C4)=0.0397 - from chisnau
Follow those steps, but add your numbers . I added one zero bassed on the problem: There are 9 students in a class: 5 boys and 4 girls. If the teacher picks a group of 4 at random, what is the probability that everyone in the group is a boy?
Hope I helped in some way!
Answer:
Step-by-step explanation:
given that a balloon is hovering 800 ft above a lake. The balloon is observed by the crew of a boat as they look upwards at an angle of 20 degrees. Twenty-five seconds later, the crew has to look at an angle of 65 degrees to see the balloon
The distance of the boat from the balloon measured horizontally in the I position = 800 tan 20
After 25 seconds distance of the boat from the balloon measured horizontally in the II position
= 800 tan 65
Distance moved by the boat in 25 seconds
= 
Speed of the boat per second =
53.702 feet per second is the speed of boat
If you add his expenses, $2.10 + $4.45 you’ll get that Luke spent $6.55 today.
