Substitute the x for 16 and put it in your calculator, so, 1/3(4-16)^2
The answer is B. When dividing exponents, you divide the coefficients and subtract the exponents from the numerator to the denominator.
So, in this case, 16/8 is 2 (eliminating C and D). Then, you subtract the exponents on r and s. For r, that’s 6-2 so the answer will be r^4. For s, that’s 3-6 so the answer will be s^-3, or 1/s^3. Put it all together and you get 2r^4/s^3, or B.
Answer:
5/36 (I won't repeat it 3 times :-) )
Step-by-step explanation:
We just have to calculate the ratio of times an action movie played in the las year, that should be a good indication of the chances for an action movie to be played next, since the reference data is quite large. We're talking about a full year, no just a week or a month.
So, 15 action movies out of 108 movies...
The probability that next movie is an action movie is: 15 / 108 , or 5/36
That's roughly 1/7.
76th floor.
60 divided by 10 is 6.
6 times 4 is 24. 100-24
is 76
