700,000+10,000+9,000+900+20+7
Answer: a set of all possible inputs for the function.
Step-by-step explanation:
Answer:
I don't think It's possible to have a division equation for this problem, However here is a multiplication one: 14 * 7 = x
x = 98
Step-by-step explanation:
14 * 7 = x
This works because there are 7 days in a week, and he ran for 14 weeks. 14 times 7 = 98. So x = 98.
Not sure if this helped, feel free to message me if you want a division equation for this? Maybe I can still help.
Answer:
Step-by-step explanation:
We would set up the hypothesis test. This is a test of a single population mean since we are dealing with mean
For the null hypothesis,
µ = 17
For the alternative hypothesis,
µ < 17
This is a left tailed test.
Since the population standard deviation is not given, the distribution is a student's t.
Since n = 80,
Degrees of freedom, df = n - 1 = 80 - 1 = 79
t = (x - µ)/(s/√n)
Where
x = sample mean = 15.6
µ = population mean = 17
s = samples standard deviation = 4.5
t = (15.6 - 17)/(4.5/√80) = - 2.78
We would determine the p value using the t test calculator. It becomes
p = 0.0034
Since alpha, 0.05 > than the p value, 0.0043, then we would reject the null hypothesis.
The data supports the professor’s claim. The average number of hours per week spent studying for students at her college is less than 17 hours per week.
