Answer:
Step-by-step explanation:
Given expression:
Note: <em>The value of "x" is undefined because the given sum is not an equation. Thus, I will simplify the expression as much as possible. </em>
Let us simplify all the distributive properties stated in the expression.
Apply the distributive property rule <u>[a(b + c) = ab + ac]</u>
Since 5(x) is being subtracted from 5(x), we get:
Finally, let us simplify the sum of the product of (5 and 4) and (5 and 2).

Answer:
8 3/10 cm
Step-by-step explanation:
Add Emile's 7th and 8th grade growth amounts together:
3 9/10 cm
4 4/10 cm (This is equivalent to 4 2/5 cm.)
-----------------
7 13/10 cm, or
8 3/10 cm
In the first position we have 10 possible numbers, and the same for the 2nd and 3rd positions becuase the numbers are replaced, so our answer is because of the multiplication rule.
In probability and statistics, there is an equation used for repeated trials. In this equation, you find the probability of getting 'r' successful events out of 'n' trials. Moreover, you should incorporate the probability of the success per trial. For a 6-sided face, each side has a probability of success of 1/6. On the other hand, the probability of each side not appearing is 5/6, because when you add these two, it would sum up to 1 as always.
Now, the equation for repeated trials is:
Total Probability = n!/r!(n-r)! * p^(n-r) * q^r
where
n = 5 tosses
r = 1 and 2 (since you want to see the probability of a side less than 3)
p = 1/6
q = 5/6
So, you add the individual probability when r=1, and when r=2.
Total Probability = 5!/1!(5-1)! * (1/6)^(5-1) * (5/6)^1 + 5!/2!(5-2)! * (1/6)^(5-2) * (5/6)^2
Total Probability = 50/243 or 20.58%
