The standard deviation of 36,18,12,10 and 9 is 10
        
             
        
        
        
Let's say that y is the weight of the mother and x is the weight of the baby.
We know that the baby is 7437 pounds less than the mother, which means you need to add 7437 pounds to the baby's weight to get the mother's.
We can show it like this:
x+7437=y.
We know what the baby's weight is (1400 lbs), so just sub it in:
1400+7437=y
y=8837 lbs
The mom weighs 8837 pounds.
        
             
        
        
        
You set 49 equal to 8x - 15
So 
8x - 15 = 49 
 +15 + 15
8x = 64
Then divide by 8 
X= 8
        
             
        
        
        
Answer:
Time to land on 11ft is 4.25 seconds
Step-by-step explanation:
Given

Required
Solve for t when height is 11ft
This implies that 
So: substitute 11 for y in

Express both sides as squares


Take square roots of both sides (ignore negative)

Solve for t


Hence, time to land on 11ft is 4.25 seconds
 
        
             
        
        
        
The correct answer is 63 minutes, what you do is divide 36/20 to get 1.8 then multiply 35*1.8 to get 63.
