Answer:
135ml
Step-by-step explanation:
glass originally 4/12 full
it then became 9/12 full
therefore 75ml = 5/12
75/5= 15ml per 1/12
15x9= 135ml total

Answer:
First, we are going to find the sum of their age. To do that we are going to add the age of Eli, the age Freda, and the age of Geoff:
The combined age of Eli, Freda, and Geoff is 40, so the denominator of each ratio will be 40.
Next, we are going to multiply the ratio between the age of the person and their combined age by £800:
For Eli: 
For Freda: 
For Geoff: 
We can conclude that Eli will get £180, Freda will get £260, and Geoff will get £360.

1) 3 x 4 = 12 + 3 = 15/10= 1.5 
1.5/4 =<em> 3/8 drink mix for one drink</em>
2) 22/8 
22/3=7.3 
<em>so 7 cups of drinks </em>
 
        
                    
             
        
        
        
Answer:
Option A
Step-by-step explanation:
Given that in a study of the relationship between geographical mobility (number of times a person has changed residences) and number of friends, Pearson's r^2 is reported as .40.
r square, being the coefficient of determination explains the variablity of one variable due to the variability of the other.  Here Mobility explains 40% variation in the number of friends is right answer.
Option B is wrong because r = ±6324, so cannot say positive or negative.
Similarly option c is wrong because we are unsure whether negative correlation.  Option d is wrong since 16% is not right .
