Answer:
x = y - a
Step-by-step explanation:
y = x + a ( subtract a from both sides )
y - a = x
Answer:
C
Step-by-step explanation:
Dot plot is usually in the form of stem & leaf. The only difference is that, stem& leaf presents the actual values while dot plot usually represent the value in dots. Hence, we can easily generate dot plot from stem & leaf!
For (a) dot plot and box plot, dot plot presents all the data while box plot presents only the five-num statistics, namely:
1. minimum
2. 1st quartile (Q1)
3. median
4. 3rd quartile (Q3)
5. Maximum
And outliers, if any!
Thus, dot plot cannot directly generate box plot
For (b). Histogram and stem & leaf. Although both usually help us understand the skewness of data distribution, however, histogram deals with frequency distribution (counts of number of occurrence) and plotted on the intervals and stem&leaf list the values.
For (d). Even though dot plot shoots up and down like the histogram, the content is different. In dot plot, it is the actual value represented in dots. But in histogram, it is the frequency distribution of the class intervals.
The statement that is not true is
B. Perpendicular lines never intersect at right angles.
The definition of perpendicular lines is that they will intersect each other at 90 degree angles.
Answer:
A
Step-by-step explanation:
I think the equation is still the same as a non-right triangle. a=(w*l)/2
As long as it's a triangle, that would be the equation. This is because for finding the area for a square or rectangle (quadrilateral) is always a=w*l, that means that the equation for any triangle is always a=(w*l)/2. The division by 2 for the triangle's equation is there because a triangle is half of a quadrilateral. So you would have to divide the quadrilateral's equation by two. Hope I helped :)
