Answer: Probability that the proportion of students who graduated is greater than 0.743 is P = 0.4755
Step-by-step explanation:
Given that,
Probability of freshmen entering public high schools in 2006 graduated with their class in 2010, p = 0.74
Random sample of freshman, n = 81
Utilizing central limit theorem,

So,

= P( Z > 0.0616)
= 0.4755 ⇒ probability that the proportion of students who graduated is greater than 0.743.
Answer:
$625 (but it's really $763.14)
Step-by-step explanation:
Use the formula I=P(1+r)^t
April=25000(1.04)^5=$30416.32
May=25000(1.0375)^6=$31179.46
$31179.46-$30416.32=$763.14
So $625 is the closest answer
Answer:
Neither
Step-by-step explanation:
Parallel must have the same slope.
Perpendicular must have reciprocal slopes.
These two contain neither.
