Answer:
120 days
Step-by-step explanation:
Tacos are served every 60 days.
Cheeseburgers are served every 8 days.
Since, both Cheeseburgers and Tacos are served today, the next day on which both will be served is gotten by finding the Lowest Common Multiple of 60 and 8.
To find the LCM,
First, we express the numbers as a product of their prime factors.
60= 2X2X3X5=2²X3X5
8=2X2X2=2³
Next, we take each of the term with the highest power and multiply.
L.C.M = 2³X3X5=120
After 120 days, Cheeseburgers and Tacos will be served on the same day.
I believe the answer is D.
3^2 is 9 and 4^2 is 16, and because 9/16 was the third term in the sequence, you raise both the numerator and the denominator by the number of the term minus 1.
So to find the seventh term, you raise the numerator and denominator by 7 - 1 = 6.
So the answer is 729/4096
Step-by-step explanation:
If the library surveyed 240 people and only 15% chose documentaries, then only 36 people chose documentaries and the other 204 chose something else other than documentaries. You had to get 15% into decimal form and to do that you move the "." in 15.0% left 2 places so you get 0.15. Then you multiply 240 by 0.15 and you get 36.
I believe the answer is A, the standard deviation is preferable to the range as a measure of variation because the standard deviation takes into account all of the observations, whereas the range considers only the largest and the smallest. Range gives an overall spread of data from the lowest to the largest and thus can be influenced by anomalies, standard deviation on the other hand, takes into account the variable data/spread about the mean and allows for statistical use so inferences can be made.<span />
