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.
The answer is B:40cm because if you times 5x4 then times 2 you get 40cm
I think it’s SSS but I’m not 100% sure
Answer:
9-3x=0
Step-by-step explanation:
Add 3x to both sides
9=3x
divide both sides by 3
3=x
x=3
Answer:
98
Step-by-step explanation:
angles 1 and 2 are congruent, the lines in each side of the shape prove this.
another way to solve if you are not sure is to subtract all of the numbers from 360. all quadrilaterals equal 360 degrees, so if you subtract each of the three angles from 360, you will be left with the last angle.
360-120-44-98=98
