Answer:
r≤9
Step-by-step explanation:
Answer:
9
Step-by-step explanation:
We can find the slope using the slope formula
m = ( y2-y1)/(x2-x1)
= ( 1 -10)/(-1 -0)
= -9/-1
= 9
Answer: In constructing a box-and-whisker plot from a data set, the minimum and maximum values are at the ends of the box.
Step-by-step explanation:
A box and whisker plot displays the five measures of data. The five measures summary is the minimum, first quartile, median, third quartile, and maximum. In a box plot, we draw a box from the first quartile to the third quartile.
Therefore, In constructing a box-and-whisker plot from a data set, the minimum and maximum values are at the ends of the box.
Hence, A is the right option,
Let a and b be odd number.
Because they are odd, by definition:
a = 2n + 1
b = 2m + 1
If we add them up:
a + b = 2n + 1 + 2m + 1
= 2n + 2m + 2
= 2(n + m + 2)
= 2k where k = n + m + 2
therefore a + b is always even.
