Answer: 0.670
Step-by-step explanation:
Given that :
Population mean (μ) = 11.5
Sample size, n = 22
Sample mean, x = 11.7
Standard deviation, s = 1.4
The test statistic ;
Tstat = (x - μ) / (s/√n)
Tstat = (11.7 - 11.5) / (1.4/sqrt(22))
Tstat = 0.2 / 0.2984810
Tstat = 0.6700594
Tstat = 0.670 (3 decimal places )
Answer:
Jamal travels at a speed of 5 mph and Diego travels at a speed of 12 mph.
Step-by-step explanation:
Jamal's speed is of x mph.
Diego's speed is of (x + 7) mph.
Opposite directions.
This means that each hour, they will be x + x + 7 = 2x + 7 miles apart.
After 4 hours they are 68 miles apart, how fast is each traveling?
Using a rule of three.
1 hour - 2x + 7 miles apart.
4 hours - 68 miles apart.
Jamal travels at a speed of 5 mph and Diego travels at a speed of 12 mph.

So what you would do is divide 988 by 26 and divide 731 by 17 and those two numbers you would add which gives you the amount of people that attended the performance
