Step-by-step explanation:
Answer:
1 solution
Step-by-step explanation:
First, simplify the equation.
3x - 6 = 7x = 3x - 1
Then, combine like terms and isolate the variable.
7x = 5
Then, divide each side by 7.
x = 5/7.
There is 1 solution and it is 5/7.
Answer:
it lies between 8 hours and 12 hours in a week
Step-by-step explanation:
Since in the question it is mentioned that the distribution consist of uni-modal, symmetric and bell shaped so here the empirical formual to be used for the mean and the standard deviation
Also the 68% would be fall within one standard deviation above and below the mean
Now
1 standard deviation below the mean is
= 10 - 2
= 8 hours
And, above the mean is
= 10 + 2
= 12 hours
Hence, it lies between 8 hours and 12 hours in a week
