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.
Answer:
C) 99 + 3x
Step-by-step explanation:
Since it's always going to cost 99, it'll stay like that since it's a constant
Since it's 3 PER person, that means 3 will have a variable: 3x
D. some parallelograms are squares
There are no choices so I’m going to assume this is simplification.
Answer:
3/4 —> this is the most simplified version of that fraction.
Explanation:
48/64 can be divided by multiple things to gain fractions. You could divide it by 2 repeatedly until arriving to a fraction wherein you couldn’t split anymore.
Ex.) 48/64 = 24/32 = 12/16 = 6/8 = 3/4
All of the above answers are equivalent to 48/64.
An easier way to reach the final answer of 3/4 would be to find the greatest common factor of 48/64. You can divide both by 16 and then get to 3/4.
Hope this helps!
