13. Imagine that you are taking a class and your chances of being asked a question in class are 1% during the first week of clas

liberstina [14]

Answer: There is probability that he will be asked a question in class during Week 7 is 64%.

Step-by-step explanation:

Since we have given that

Probability that question in class being asked during Week 1 = 1%

Probability that question in class being asked during Week 2 = 2%

Probability that question in class being asked during Week 3 = 4%

and so on.

So, we need to find the probability that question being asked in class during week 7.

Since it forms geometric series:

1%, 2%, 4%, ........

So, we need to find the 7 th term:

$a_n=ar^{n-1}\\\\a_7=ar^{7-1}\\\\a_7=1(2)^6\\\\a_7=64\%$

Hence, there is probability that he will be asked a question in class during Week 7 is 64%.

Need help pls. I try many ways of this answer

LekaFEV [45]

Answer:

3(t+2)

Step-by-step explanation:

As with any problem involving division of fractions, you can invert the denominator and multiply.

Your knowledge of the factoring of the difference of squares helps. If that doesn't work for you, you can always use synthetic division or polynomial long division to find the quotient of (t^2-4) and (t-2).

$\displaystyle\frac{\frac{4t^2-16}{8}}{\frac{t-2}{6}}=\frac{4(t^2-4)}{8}\cdot\frac{6}{t-2}\\\\=\frac{3(t+2)(t-2)}{t-2}=3(t+2)$
