Answer:
180=x+139
x=41
90=x+18
x=72
Step-by-step explanation:
the 1st one is a straight line, it is a 180° angle. To find the missing piece, x, you need to do 180-139 and get 41°.
the 2nd one is a right angle (because it has a square at the inner corner), its 90°. To find x, you need to do 90-18 and get 72°
Answer:
21
Step-by-step explanation:
just put 21 ok that is the right answer
Answer:
The data is skewed to the bottom and contains an outlier.
Step-by-step explanation:
1. Test for outlier
An outlier is a point that is more than 1.5IQR below Q1 or above Q3.
IQR = Q3 - Q1 = 74 - 51 = 23
1.5 IQR = 1.5 × 23 = 34.5
51 - 15 = 36 > 1.5IQR
The point at 15 is an outlier.
2. Test for normal distribution
The median is not in the middle of the box.
Rather, it cuts the box into two unequal parts, so the data does not have a normal distribution.
3. Test for skewness
The longer part is to the left of the median, so the data is skewed left.
