"-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>
Vertical line is x=something
we see
(x,y)
(-2,3)
x=-2 is the equation
23. 5+9((9)-8)2, 5+9(1)2, 5+18=23
Answer: 8 quartets can be formed.
1 singer will be left over.
Step-by-step explanation:
A quartet is a group of 4 members.
Given: The women'schorus has 33 members.
The number of quartets can be formed = (Total members) divided by (4)
= 33 ÷ 4
By solving 33 ÷ 4 we get 8 as quotient and remainder as 1 such that
33 = 4 x 8 +1
Hence, 8 quartets can be formed.
1 singer will be left over.
Answer:
mass of mangos = 300g
mass of apples = 200g
mass of pears = 150g
Step-by-step explanation:
lets first reduce the ratio
12:8:6
is the same as
6:4:3
this means the the denominator of our fractions will be 6 + 4 + 3 = 13
hence
mangos = 6/13 of 650g
6/13 * 650 = 300
apples = 4/13 of 650g
4/13 * 650 = 200
pears = 3/13 of 650g
3/13 * 650 = 150
