Answer:
x > 100
Step-by-step explanation:
Consider x as "Chicago Cubs".
The alligator sign always points/goes to the number (or food) with the highest value (or bigger meal).
Since Chicago Cubs wins is bigger than 100, you can write the inequality as follows:
x > 100

Answer: Radius is 15.9975 meters.
Step-by-step explanation:
The formula to find radius of circle is r=
so plug in our known variables and solve...
r=
r=
r=15.9975
Answer:


Since the calculated values is lower than the critical value we have enough evidence to reject the null hypothesis at the significance level of 2.5% and we can say that the true mean is lower than 36 years old
Step-by-step explanation:
Data given
represent the sample mean
represent the sample standard deviation
sample size
represent the value that we want to test
represent the significance level for the hypothesis test.
t would represent the statistic (variable of interest)
represent the p value for the test (variable of interest)
System of hypothesis
We need to conduct a hypothesis in order to check if the true mean is less than 36 years old, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
And replacing we got:
Now we can calculate the critical value but first we need to find the degreed of freedom:

So we need to find a critical value in the t distribution with df =21 who accumulates 0.025 of the area in the left and we got:

Since the calculated values is lower than the critical value we have enough evidence to reject the null hypothesis at the significance level of 2.5% and we can say that the true mean is lower than 36 years old
The answer is 15 or 3 I think but I'm not sure
