Answer:
3,500
Step-by-step explanation:
70% is equal to 0.70.
When you need to find a percent of a population, you multiply the decimal form to the population.
Therefore, with 70% of 5000, you multuiply 5000 by 0.70 which will give you 3500.
3,500 students would select roller coasters as their favorite ride.
Find some graphing paper and graph away..
i.e. Sub in x = 0 and find what y = ?
y = 1/2(0) + 3
y = 3
So we know the coordinate (0,3)
When x = 4 , y = ?
y = 1/2(4) + 3
y = 4/2 + 3
y = 2 + 3
y = 5
So we know another coordinate (4, 5)
When x = -4, y = ?
y = 1/2(-4) + 3
y = -4/2 + 3
y = -2 + 3
y = 1
So we know another coordinate (-4, 1)
Putting it all together, the coordinates: (-4, 1) , (0, 3) and (4, 5) should be plenty sufficient to graph and then draw a line of best fit connecting them.
