Answer:
Experimental probability of head = 2 / 5 or 40%
Step-by-step explanation:
Given:
Total chances of getting head = 20 times
Number of heads come = 8
Find:
Experimental probability of head
Computation:
Experimental probability of head = Number of heads come / Total chances of getting head
Experimental probability of head = 8 / 20
Experimental probability of head = 2 / 5 or 40%
Ways to spot if an expression is not a polynomial:
1) If there is a negative exponent
2) If there is division by a variable
3) If the power is something other than a non-negative integer
If any of these conditions exist, the expression will not be a polynomial. Now consider the options. Option A has negative exponent, Option B involves division by a variable and Option D has a exponent which is not a number.
So, from the given options, option C is the only polynomial
Let the missing number be x
Mean is the total sum of data over the number of data therefore,
(11+20+x+3+1) / 5 = 9
Then simplify
(35 + x) / 5 = 9
Then multiply 5 to both sides
35 + x = 45
Then subtract 35 to both sides to find x
X= 10
