Given :difference between 2 whole number = 66ratio of the 2 whole number =2:5Let:1 whole number be 2x2 whole number be 5xA/Q
difference between 2 whole number = 66
Let's turn it into algebraic equation:
5x - 2x = 663x= 66x =66 /3x =22
Now Let's put value of x to find two whole numbers
Finaly :1 whole number = 2x1 whole number = 2×221 whole number =44
2 whole number = 5x2 whole number = 5×222 whole number = 110
Answer:
LCL = 59.26 to two decimal places
Step-by-step explanation:
Here, we want to estimate the LCL of the population mean with 90% confidence
We proceed as follows;
Given alpha = 0.1, then Z(0.05)=1.645 (from standard normal table), s = 15
Mathematically;
LCL =x_bar -Z*s/√( n)= 62 - (1.645 * 15)/√81
LCL = 62- (24.675)/9 = 59.2583
LCL = 59.26 to two decimal places
Answer:
104 mins, 468 mins
Step-by-step explanation:
Let the time spent on puppy videos = 2x
Where x is the number of weekends.
Time spent on regular TV = 9x.
So total time spent is 572 mins
i.e 2x + 9x = 572
i.e 11x = 572
So x = 52.
So time spent on puppy videos = 2 X 52
= 104 mins
So time spent on puppy videos = 9 X 52
= 468 mins.
