Answer:
g(2) = 3
Step-by-step explanation:
g(x) = x² - 1.
Substituting 2 for x in this formula, we get:
g(2) = 2² - 1, or g(2) = 3
Answer:
E looks like it is most congruent
Step-by-step explanation:
Answer:
As we can see the relative frequencies are not too different the average for all the relative frequencies is and the maximum absolute difference |0.143-0.109|= 0.034 is not enough higher to conclude that we have significant difference from the average or expected value.
Step-by-step explanation:
For this case we have the frequency of the number of times that the outcome happens per each day of the week:
Day Frequency
Monday 52
Tuesday 64
Wednesday 70
Thursday 59
Friday 60
Saturday 43
Sunday 42
We can begin findind the total for the frequency and we got:
52+64+70+59+60+43+42=390
And now we can calculate the relative frequency for each case like this:
As we can see the relative frequencies are not too different the average for all the relative frequencies is and the maximum absolute difference |0.143-0.109|= 0.034 is not enough higher to conclude that we have significant difference from the average or expected value.
In order to test this more formally we can use a chi square test but the problem not ask for this.
