Answer: 
Step-by-step explanation:
Given expression: 
The law of exponents are given by :_

Using PEDMAS, first we solve division, we get

Now, using product law of exponent we get

We can rewrite the asked question like this:

wherein X_1 and X_2 are random variable with the same given normal distribution. Then mean of

is zero and the variance
can be computed like this:

So, the random variable

follows a normal distribution
with means 0 and standard deviation 9.6.
The median of the law N(0,9.6) is 0.
So the expected difference of the score is 0.
The answer is:
A) If a = b, then a + c = b + c.
and C) If w + 2 = 7, then w + 2-2 = 7- 2.
Answer:
As per the statement:
One bread recipe calls for 2 1/3 cup of flour another bread recipe called for to 1/2 cup of flour .
First we calculate how much flour the two recipes combine call for, by adding the amount of flour needed for both the recipes:
⇒
⇒
Tim would use
cup of flour for two recipe.
We have to find how much flour will he have left over.
Tim has 5 cup of flour.
Subtract 17/6 from 5

Therefore, Tim would have
left over.
Answer:
3 times the number of yards
Let f represents the number of feet
f = 3 * y
Step-by-step explanation:
Number of feet 3 6 9 12
number of yards 1 2 3 4
1*3 = 3
2*3 - 6
3*3 =9
4*3 = 12
number of feet is 3 times the number of yards
Let f represents the number of feet
and y represents the number of yards
number of feet is 3 times the number of yards
f = 3 * y
