Answer:
0.94 ft/sec
Step-by-step explanation:
Airport: 2 feet per second.
Total distance 152 ft in the same amount of time it takes him to talk 72 feet on the pavement.
152/2 = 76 - This is how many seconds he was walking in the airport.
He walked 76 seconds and moved 152 feet.
So that means if the SAME time was used so 76 seconds he walked 72 feet, then we can do 72ft/76sec to get 0.94ft/sec
Answer:
slope = -4
Step-by-step explanation:
Given the following points on the graph: (-1, 4) (1, -4)
Let (x1, y1) = (-1, 4)
(x2, y2) = (1, -4)
Use the following slope formula:


Therefore, the slope of the line is -4
The answer is C
Hope this helped
Answer:
In statistics , the population is the set of all possible observations as per the researcher's objective .
For example if a researcher wants to find the average height of teenager of age group between 13 year and 15 years in Seattle, he will need the data of the population of height of teenager of age group between 13 year and 15 years in Seattle.
Here , A teacher needs to find out how many seventh graders will be going on a field trip.
Clearly as per her objective she need the data of all seventh graders .
So , the best describes the population that the teacher should survey would be : All seventh graders.

Answer:

Step-by-step explanation:
zeroes are when you plug in that x value and get y=0
therefore if you set x = that number and solve for 0 you get a "function"
multiplying these together will yield the complete 3rd degree polynomial
x = 1
x-1=0
x=7
x-7=0
x=-4
x+4=0

If needed you could expand but I'm too lazy
