Answer: Brian sold 35 tickets.
Step-by-step explanation: Given that Brian had 42 class fair tickets to sell and he sold of the tickets.
We are to find the number of tickets that Brian sold.
We have
Total number of tickets that Brian had = 42.
Since he sold five-sixth of the total tickets that he had, so the number of tickets that Brian sold is given by
Thus, Brian sold 35 tickets.
equations in factored form?
Answer:
The Zero Product Property states that if ab = 0, then either a = 0 or b = 0, or both a and b are 0. When the product of factors equals zero, one or more of the factors must also equal zero. Once the polynomial is factored, set each factor equal to zero and solve them separately.

A) variance = 222.7, standard deviation = 49,595.9
B) variance = 49,595.9, standard deviation = 24,798
C) variance = 49,595.9, standard deviation = 222.7
D) variance = 57,861.9, standard deviation = 240.5
Answer:
Part 1) variance = 49,595.9
Part 2) standard deviation = 222.7
Option C
Step-by-step explanation:
we have
set of data
step 1
Find the mean
Adds the values and divide by the number of values
In this problem the number of values is 7
step 2
for each number: subtract the Mean and square the result
step 3
work out the mean of those squared differences
----> this value is called the "Variance"
step 4
The standard deviation is the square root of the variance
so
The standard deviation is equal to
