Answer:
i)
ii)
And replacing we got:
iii)
Step-by-step explanation:
Let X the random variable of interest "number of inhabitants of a community favour a political party', on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
Part i
We want this probability:
Part ii
We want this probability:
And we can use the complement rule and we have:
And if we find the individual probabilites we got:
And replacing we got:
Part iii
We want this probability:
And replacing we got:
Answer:$92.72
Step-by-step explanation:P = price of item
1.08P+3=103.14
-3=-3
1.08P=100.14
Divide by 1.08
P= 92.72
Answer:
Step-by-step explanation:
Area of a square tile = 90 square inches
Let the side length of tile be "L"
<u>Condition:</u>
Area = 90
L * L = 90
L² = 90
Taking sqrt on both sides
L = √90
L = 3√10

To find the zeros set the equation equal to zero:
x^2 - 5x +4 = 0
Factor:
(x-4) (x-1) = 0
Now solve each set of parenthesis so that they equal zero:
(x-4) = 0, x =4
(x-1) = 0, x = 1
The zeros are 1,4
