So the total is 75000 miles, so that is what the whole equation equals. So we start out with 75000=. Then, 200 is the number that is multiplied by the amount of weeks, so we then have 75000 = 200x. Finally, 50670 is the start, so we add it to the end. The final equation is 75000 = 200x + 50670.

Hi , you have to divide the numerator and the denominator , if you get a decimal you just have to move the period 2 spaces to the right.
For example
3/8 -0.375
0.375 - 37.5
Answer:
h = 7
t = 11
Step-by-step explanation:
5t + h = 62
2t + h = 29
h+5t = 62
h+2t = 29
h = 7
t = 11
Answer:
28
Step-by-step explanation:
4x + 9x + 8x = 147
21x = 147
x = 147/21
x = 7

The shortest side will be 4x
4*7 = 28
Answer: (110.22, 125.78)
Step-by-step explanation:
The confidence interval for the population mean is given by :-
Given : Sample size = 463
Significance level : 
Critical value : 
We assume that the population is normally distributed.
Now, the 90% confidence interval for the population mean will be :-
Hence, 99% confidence interval for the mean study time of all first-year students = (110.22, 125.78)
