Answer:
896
Step-by-step explanation:
14 of 20 teens eats breakfast every morning.
The percentage of those who eat breakfast every morning
= 14/20 x 100%
= 0.7 x 100%
= 70%
So, 70% of 20 teens eat breakfast every morning.
The reasonable prediction for the number of teens that eats breakfast every morning from 1280 teens will be 70% of 1280.
70/100 x 1280
0.7 x 1280
896
The prediction would be 896 out of 1280 teens eats breakfast every morning

Answer:
f(x) = -34x + 320
Step-by-step explanation:
In the figure attached, the graph of the data and the options are shown.
We can see from the graph that the best fit line for the data would have a negative slope (as x values increase, y values decrease) and a positive y-intercept (the y value at x = 0). The only option that satisfies these two criteria is f(x) = -34x + 320
