So approximately 14.5% of the scores are higher than 600. This means in a sample of 7500, one could expect to see

scores above 600.
now let's recall that a full circle has 360°, so then 1140 = 360 + 360 + 360 + 60.
namely, 1140 is 3 full-go-around the circle and then it lands on the I Quadrant at 60°. Thus cos(1140°) = cos(60°).
what's that cosine of 60°? Check the picture below.
Answer:
y=-13
Step-by-step explanation:
Plugging in -7:
y= (-7)2 + 1
-7 * 2 = -14
So:
y= -14 + 1
-14+1=-13
Answer:
$54.25
Step-by-step explanation:
decide 38.75 by 5 to get what each cost then multiply by 7 to get your answer
