Answer:
75
Step-by-step explanation:
Answer:
They will change color at the same time in the next 180 seconds or 3 minutes
Step-by-step explanation:
Here, we have two spotlights which change colors at intervals.
While one changes every 60 seconds, the other changes every 90 seconds. Now, we are concerned with knowing when they will both change colors at the same time or instant.
The key to solving this is straightforward. What we need to do is to find the lowest common multiple of both numbers i.e 60 and 90.
The lowest common multiple of both is 180 seconds. This means in the next three minutes, both spotlights will change color at the same time.
Let’s take this by counting;
Spotlight A; 60 , 120 , 180
Spotlight B: 90 , 180
Sequence: 4, 13, 28, 49
Now, differences between numbers = 13-4, 28-13, 49-18
= 9, 15, 21
We can see, difference is increasing by 6 at each step, so it would be 27 for next.
Next number = 49 + 27 = 76
In short, Your Answer would be 76
Hope this helps!
Answer:
60
Step-by-step explanation:
V = lwh
V= 4x3x5
V=60
To answer this, we will look at simple definitions of each term. From the definitions, it will be clear which one is correct.
<u>What is mode?</u>
It is the most occurring number.
<u>What is interquartile range?</u>
It is the difference between third quartile and first quartile.
<u>What is range?</u>
It is largest number minus the smallest number.
<u>What is mean absolute deviation (MAD)?</u>
It is the average distance of each data point from the mean.
<u>What is a quartile?</u>
It is one of the four groups in which a dataset is divided.
From the simple definitions of each term, we can clearly see that Mean Absolute Deviation (MAD), answer choice D, is the correct answer.
Answer: Mean Absolute Deviation
