6w-y=2z
6w=2z+y
w=(2z+y):6
w=(z:3)+(y:6)
Answer:
Labrador retrievers
Step-by-step explanation:
We know that the mean 
is:
and the standard deviation 
is:
The probability that a randomly selected Labrador retriever weighs less than 65 pounds is:
We calculate the Z-score for X =65
So
Looking in the table for the standard normal distribution we have to:
.
Finally the amount N of Labrador retrievers that weigh less than 65 pounds is:

The question is asking what will we get if we add 1+1.
Let us use an example to understand this.
Example:
Suppose Amy has 1 ice cream and her brother Ruth has also got one ice cream.

So we see that 1 and 1 add up to give two ice creams and so two ice creams are finished by them both.
Applying this to our question adding 1 and 1 gives us 2.
Answer : 1+1 =2
