Number of aircrafts = 2939.93 + 233.517 * (years since 1990).
The predicted number of aircrafts flying in 1992 (1922 does not make sense for this equation because it returns a negative number of aircrafts) is found by pluging in the years since 1990 to 1992 = 1992 -1990 = 2 =>
number of aircrats = 2939.93 + 233.517 * (2) = 3406.96.
That is the predicted number.
The actual number is on the graph. You just go to the explanatory value 2 (years since 1990) on the horizontal axis, move straight upward until you reach the corresponding point on the graph, and read its vertical coordinate (go horizontally to the left until the vertical axis)
Answer:
18m I guess
Step-by-step explanation:
divide distance by time
32 /1.25 = 25.6 miles per hour
Answer:
Food B has fewer calories.
Step-by-step explanation:
To find the unit rate we had to transfer both to have the denominator. To do that we have to find a common denominator both 4 and 3 have. The common denominator is 12. We then use 12 as a denominator and solve. (Sorry I don't really know how to explain.)
Food A=
12 ÷ 4 is 3, 3 × 3 = 9.
9/12
Food B=
12 ÷ 3 = 4, 4 × 2 = 8.
8/12
Answer:62x
Step-by-step explanation: subtract 64 by 2 then add an x
