In which quadrant does the point (–10, 9) lie?
a.
quadrant i
b.
quadrant ii
c.
quadrant iii
d.
quadrant iv
need an actual

B is the correct option.

Step-by-step explanation:

We have been given the coordinate of the point as (-10,9). The coordinate is in the form (x,y). Thus, we have

x = -10

y = 9

The value of x is negative and the value of x is positive. We know that in quadrant II, the values of x is negative and y is positive. Please see in the attached diagram.

Hence, the point (-10,9) is in Quadrant II.

B is the correct option.

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
