Answer:
1st option
Step-by-step explanation:
Consider the coordinates of F and F'
F (- 3, 4 ) and F' (- 1, 3 )
To go from - 3 → - 1 in the x- directions , means adding 2
To go from 4 → 3 in the y- direction means subtracting 1
Then translation rule is
(x, y ) → (x + 2, y - 1 )
V (velocity) = distance / time
So distance = velocity x time = 20 x 10 = 200 ft.
Answer:
Step-by-step explanation:
Ryan works mowing lawns and babysitting. He earns $8.20 an hour for mowing and $7.70 an hour for babysitting. Therefore, the expression for the total amount that he would earn if he mows lawns for x hours and babysits for y hours would be
8.2x + 7.7y
Therefore, the amount that he would earn for 3 hours of mowing and 7hours of babysitting is
(8.2 × 3) + (7.7 × 7)
= 24.8 + 53.9
= $78.7
It would be 49
10+13=23
23+13=36
36+13=49
I think this is right
Answer:
Step-by-step explanation:
-The total number of outcomes is 4.
-Given that the outcomes occur with the same frequency.
-Therefore they all occur with the same frequency, 1/4=0.25
-The probability distribution for the duration of a service call is attached.
