Answer:
Option A) 126
Step-by-step explanation:
This month Papa has seen on his bird feeder the birds are :
Blue jays = 59
Black crows = 68
Red robins = 12
Cardinal = 1
Total birds are seen in the month
= 59 + 68 + 12 + 1 = 140 birds
Out of 140 birds there are 59 Blue jays. Now we calculate what percentage of blue jays visited this month.
59 Blue jays out of 140 birds
To get the percentage :
×100
= 42.14% rounded to 42% approx.
Out of 140 birds blue jays are 42%.
If 300 birds visit Papa's bird feeder, expected numbers of blue jays are :
= 42% of 300
= 0.42 × 300 = 126 blue jays
126 blue jays are expected to see on Papa's feeder.

You will need data that logs the changes in speed from various, consecutive events. Which you can use to calculate the difference in speed and determine wether the speed is increasing or increasing.
Otherwise, you only need the initial and finak value to find the difference.
