Answer:
Step-by-step explanation:
Rotations are easy when its multiples of 90 degrees; 90,180,270,360. Treat them like they’re a complex number like [x+yi]*i=[-y,xi] so rotating by 90 degrees and 180 is i squared [-1]! So [-3,2] rot90 is [-2,-3].
Reflection about the y=x line is change places. [x.y]=[y,x].
So [-2.-3] reflected about the y=x line is [-2.-3]=[-3.-2],
Compile a list of these transform is best practice technique in this area.
Answer:
cost to afford to bring these calculators is $8.4
markup on retail = 5.6
Step-by-step explanation:
given data
selling price = $14
mark up on selling = 40% = 40/100 = 0.40
to find out
What cost can Mike afford to bring these calculators
solution
we calculate markup on retail that is mark up on selling of selling price
markup on retail = 0.40 × 14
markup on retail = 5.6
so
cost to afford to bring these calculators = 14 - 5.6
cost to afford to bring these calculators is $8.4
Answer:
53
Step-by-step explanation:
Take the mean of each row in the accidents reported column so for example 0-4 would be 0+4/2 = 2
Then times it by the frequency which in this case is 15:
2 x 15 = 30
Do this for each rows and then add it all up:
30 + 28 + 120 + 34 = 212
Then divide it by number of row which in this case is 4:
212/4 = 53
