Answer:
A. 525 feet
Step-by-step explanation:
If every hour their altitude increased by 135 then their would be an increase of 675 (135 × 5) after 5 hours. To find their altitude 5 hours earlier then you would subtract 675 from their current altitude. 1,200-675=525 feet
Answer: The Awnser to this equation is C, AE is equal to 25
<span>3 is 1.0 below the mean. That is 1.0 / 0.9, or 1.1111... standard deviations below the mean.
So look up z < -1.11 on your graphing calculator.
It should be around 0.1335 or 13.35%</span>

Answer:
(d) 28
Step-by-step explanation:
When you are asked to evaluate g(n) for some value of n, put that value where n is and do the arithmetic.
g(n) = 3n -2
g(10) = 3·10 -2
= 30 -2 = 28
Answer:
625
Step-by-step explanation:
<u>here we are in an inverse proportion situation :</u>
<em>As the number of days increases </em>
<em>when the number of students decreases and vice versa.</em>
__________________
Say n is the original number of students.
___________________________________________
<u>After 15 days, the rest of food is enough for n students for 45 days, </u>
<u>or enough for n+500 students for 25 days.</u>
Then
45n = 25×(n + 500)
Then
45n = 25n + 25×500
Then
45n - 25n = 25×500
Then
20n = 12500
Then
n = 12500÷20
= 625
and thus , there were 625 students in the hostel.
