Answer: $30.40
Step-by-step explanation: If you know that the original price is $38 and it was marked down by 20%, you could multiply the original price by ".80". This represents 80% of the original cost, since it was marked down by 20%. By multiplying $38 by .80, you end up with $30.40.
Hope this helps!
Answer:
1. A
2. C
Step-by-step explanation:
1.The mean is the best measure when the data is not skewed and when it has no outliers. If it is skewed or has outliers, we need to use something like the median or mode. In this case, the most clustered and normal data, with no outliers, is choice A.
Why not B: It has an outlier at 3.
Why not C: It's all over the place, near 70 and then near 25ish.
Why not D: There's a huge outlier at 301 that will bring up the mean, which isn't accurate to the actual center.
2.The mode is most helpful when there is repeating data. In this case, the one that works is choice C, because it has a clear mode of 36.
Why not A or D: They don't have clear modes, because they have two values that have more than one occurence.
Why not B: It has no mode.
