Answer:
In the graph attached there is a sample generated with a correlation coefficient r=-0.5.
Step-by-step explanation:
A value of r that is -0.5 shows that there is a certain correlation and that this correlation is negative.
As there are no examples in this question, I searched for a generator of random samples with a user-input correlation coefficient between the two variables.
In the graph attached there is a sample generated with a correlation coefficient r=-0.5.
Step-by-step explanation:
Take John's sister's age as "x"
So, so twice his sister's age means = 2x

Answer:
the total for her to leave is 67.28 dollars. the tip is 8.78 dollars
Step-by-step explanation:
Given that a kitten weighs four whole pounds and 2/3 of a fifth pound.
In this type of problem it is always best to break the given statement into smaller pieces then writing expression for each piece will be more easy.
"fifth" means 1/5.
so 2/3 of a fifth means product of 2/3 and 1/5 which is
Now total weight is given by
4 whole pounds and 2/3 of a fifth
Hence required fraction for the answer is 
.
