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.
Answer:
Claire borrowed $500 from her father.
Step-by-step explanation:
Interest = $90
p = ?
r = 6% or 0.06
t = 3
Simple interest formula is :
Putting values in formula we get;
p = $500
Hence, Claire borrowed $500 from her father.
Answer: 21cm
Step-by-step explanation:
To find the area of a rectangle you just multiply the length by the width. In this case we have 12(width) x ?(length) = 252. To solve we would just divide the area by the known measurement to find the missing one, so 252/12 =21cm
Answer:
that is 60 percent (calculated percentage %) of number 100? Answer: 60.
Given:
A line segment AB.
A point is 
of the way from A to B.
To find:
The coordinates of that point.
Solution:
Section formula: If a point divide a line segment in m:n, then
From the given figure, it is clear that the two end points of the line segment are A(-4,-5) and B(12,4).
Let the unknown point be P. The point is of the way from A to B. It means,
Let AP and AB are 3x and 10x, then
It means, point P divided the line segment in 3:7.
Using section formula, we get
Therefore, the coordinates of the required point are (0.8, -2.3).
