Answer:
The answer to your question is:
Fraction he has review = 17/36
Fraction he have to study = 19/36
Step-by-step explanation:
Data
Monday studied = 2/9
Tuesday = 1/4
Fraction he has review = ?
Fraction he has left = ?
Process
As the denominator is 9, consider the whole is 9.
Then: Fraction left on Monday = 9/9 - 2/9
= 7 / 9
Fraction left on Tuesday = 7/9 - 1/4
= (28 - 9) / 36
= 19 / 36
Fraction he has review = 17/36
Fraction he have to study = 19/36
Answer:
The general relation about a geoemtric sequence is

For the first sequence, we have


Which is a system of equations. We can isolate a variable in the first equation to replace that expression into the second equation.


![r^{2}=\frac{147}{3}\\ r=\sqrt[2]{49}\\r=7](https://tex.z-dn.net/?f=r%5E%7B2%7D%3D%5Cfrac%7B147%7D%7B3%7D%5C%5C%20%20r%3D%5Csqrt%5B2%5D%7B49%7D%5C%5Cr%3D7)
Now, we replace this value to find the other one

Therefore, the explicit rule function is

Now, we use the same process for the second sequence.

The second equation is

Now, we solve the following expression

We solve for 

Then

Therefore, the function that models the second sequence is

Notice that
is the dependent variable and
is the independent variable.
Answer:
Step-by-step explanation:
60= s+5 + 2s-5 + s
60 = 4s
15 = s
the short side is 15
the 2nd side is 20

Answer:
p value= 2.228
Step-by-step explanation:
since average of two groups is being compared two-sample t-test will be performed.
degrees of freedom= 12-2=10
at α=.025 from t table
p value= 2.228
