Answer:

D. 9

Step-by-step explanation:

We have been given an equation and we are asked to find the solution for our given equation.

t(7-2)=9\cdot 7-9\cdot 2

Upon factoring out 9 from right side of our equation we will get,

t(7-2)=9(7-2)

t(5)=9(5)

5t=9*5

Upon dividing both sides of our equation by 5 we will get,

\frac{5t}{5}=\frac{9*5}{5}

x=9

Therefore, the solution to our given equation is 9 and option D is the correct choice.

If a set of data has mean 60 and variance 9 then it's coefficient of variation is
loris [4]
Coefficient of variation is calculated by dividing the standard deviation by the mean multiplied by 100. Given a data set with mean equal to 60 and variance equal to 9, we can calculate the coefficient of variation by finding the value of the standard deviation which is the square root of the variance. so standard deviation is equal to square root of 9 which is 3. Then, the coefficient of variation is equal to 3/60*100 which is equal to 5%.
