I the average score is 750 and standard deviation ( sigma ) is 50 points, then score 700 - 800 is between (750 - 1 sigma) and (750 + 1 sigma).
That is 34.1 % + 34.1 % = 68.2 % of the whole population.
2,000 · 0.682 = 1.364
We expect 1,364 students to score between 700 and 800 points.
No, they do not have a pattern nor do they flow to get her the difference between 6 and 11 is 5, whereas the difference between 11 and 17 is 6.
Answer:
f(-5) = 19
Step-by-step explanation:
f(t) = -3t+4
Let f(t) = 19
19 = -3t+4
Subtract 4 from each side
19 - 4 =-3t+4-4
15 = -3t
Divide each side by -3
15/-3 = -3t/-3
-5 = t
Okay so. im not good at explaining. but ill try my best
you go with your basic X over Y soooo 2X you would go up 2 because its a positive number. and to the.. left 3 becuse it - if it was a + you would go to the right 3 but sense its -3y you go to the left
so fare your going to go from the -9 point on your graph up 2 over 3
and if its just Y ots over 1
i really hope this makes sence and helps
