recognizirtg equivalent sequences of transformations
the point (5, 3) has an image of (2, -1) under a translation of left 3 and down 4 units. which
sequence of transformations produces the same image?
translate left 2 units and down 3 units, and then reflect over the x-axis.
© translate left 3 units and down 2 units, and then reflect over the x-axis.
reflect over the x-axis, and then translate left 2 units and down 3 units.
reflect over the x-axis, and then translate left 3 units and down 2 units.

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.

answer: 1.06 km per sec

step-by-step explanation:

39.6 m=63.72 km

60 min in an hour so 63.72/60=1.06

false, it is 3

-35* 3 = -105
