"-the time people spend at work and the number of friends they have"
would be "causation"; because the more/less time someone spends at work is implied to be the *cause* of their number of friends.
"-the length of a person's hair and his or her math skills"
would be "no relationship" seeing as there's nothing that relates these two variables that could have an affect on the outcome of one or the other.
<span>"-a student's test scores in math and physics" would be "correlation" because the two subjects are similar enough that any outcome in one could very well be similarly related to the outcome in the other. </span>

Answer: 10.4
Step-by-step explanation:
According to the right angle triangle, the longest side is the hypothenus, d side facing the angle is the opposite and the other side is the adjacent
So we this we will use tan
Tan 30= opp/adj
Tan 30= 6/x
Cross multiply
Xtan30= 6
X= 6/tan 30
X= 6/1/square root of 3
X= 6 x square root of 3
X= 10.39 ~ 10.4
Answer:
0.006369
Step-by-step explanation:
Given that a test consists of 10 multiple choice questions, each with five possible answers, one of which is correct.
By mere guessing p = probability for a right answer = 1/5 =0.20
There are two outcomes and each question is independent of the other.
X no of questions right is Bin (10,0.20)
the probability that the student will pass the test
= prob of getting more than 60%
=
=0.006369
