Answer:
b. 0.216
Step-by-step explanation:
For each student, there are only two possible outcomes. Either they have a job, or they do not. The probability of a student having a job is independent of other students. So we use the binomial probability distribution to solve this problem.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
60% of the students at a large university have a job
This means that
If three of these students are randomly selected what is the probability all three have jobs?
This is when . So
So the correct answer is:
b. 0.216
Answer:
The answer is y=1.5x
Step-by-step explanation:
When you do 4 x 3, that gets you 12, but on the table it says 6. You can get rid of that option.
When you do 4+2, it gets you 6. But when you do 6+2, it gets you 8. On the table it says 9. You can get rid of that option.
When you do 4 x 2, you get 8, but the table says 9. You can get rid of that option.
That then only leaves you with 1.5, which works with all of the values.

We can look at 2 similar triangles.
1st triangle has legs: a vertical pole and its shadow, and
2nd triangle has legs legs : a child and his(her) shadow.
We can write a proportion:
height of a pole/height of a child= shadow of a pole/shadow of a child
8/4 = 5/shadow of a child
shadow of a child=(5*4)/8=5/2 ft
Answer: 5/2 ft
