Answer:
0.6
Step-by-step explanation:
In this question, the | symbol means "given", so we can phrase the question as "Find the probability that a student watches more than one hour of TV given that they are in the 6th period class"
Next, because there is a 100% chance that the student is in the 6th period class, we can disregard the results of the 3rd period class.
Given that the student is in the 6th period class, there are 15 total students (as 9+6=15 = the sum of the yes and no answers for 6th period) and 9 students that said yes. Therefore, there is a 9/15 = 3/5 = 0.6 probability that a student watches more than 1 hour of TV given that they are in the 6th period class
You can just multiply the area of the base times the height. The base is a triangle which has an area of bh/2. If we let b=base, h=height (of the triangle base) and H=the height of the prism, then:
V=Hhb/2, in this case:
V=17*2*1/2
V=17m^3
Answer:
5 knots
Step-by-step explanation:
In order to find the speed Jesse travels in knots, you need to find his unit rate, or miles per hour. Setting up a fraction and dividing will give you how many miles her traveled per hour:

Since Jesse traveld at 6mph, you can set up a proportion (equivalent ratios) using the ratio of 1 knot to 1.2 miles per hour to find the number of knots in 6mph:
where x = the number of knots
cross-multiply and divide: 1.2x = 6 or x = 5 knots
