Answer:
The P-Value is 0.009999
Step-by-step explanation:
we have 5 categories
df=5-1=4
With alpha = 1%, the critical Chi-square value is 13.277
The P-value is define as the shows the degree of inconsistency of our data set with hypothesis.
using a significant level of 0.01,
The P-Value is 0.009999. The result is significant at p <0.01
Answer: a) 15 b)
Step-by-step explanation:
Let X be the number of days:
a)
For LESSONS:
Jordan does 10 / day ( 10*X)
Marco 5 / day ( 5*X)
Junyi 5 / day ( 5*X)
For TESTS:
Jordan does 5 / day ( 5*X)
Marco 10 / day ( 10*X)
Junyi 8 / day ( 8*X)
for each they need a total of 300
a) days for the lessons
b) days for the tests
so they need 15 days to finish both tasks
now if Junyi gets sick we just eliminate his contribution
a) days for the lessons
b) days for the tests
so in 20 days they will finish without him
If jordan works 10 hours a day, we just replace him with 10/24
a) days for the lessons
b) days for the tests
so at the end to complete both tasks they need 29.58 days
Composing functions just means to feed the ouput of the inner one as the input for the outer one.
So, the following writings are equivalent:
Using the second form, we can see that the first thing to do is to compute , which is given:
This means that we can update the fomula:
So, now we have to compute . Given
, we know that
doubles the input and adds one. In this case, the input is
, so we have to double this and add one:
So, we have
Similarly, from , we understand that
just adds 3 to the input. In this case, the input is
, so we'll add 3 to this quantity:
So, we finally have
