Answer:
12%
Step-by-step explanation:
let x represent the actual number of members last year.
current members = 675 and with an increment of 13% over previous year
to find the increment
(675 - x) / x = 0.13
675 - x = 0.13x
collect the like terms
675 = 0.13x + x
675 = 1.13 x
x = approx 597 members were there last year
its hope to increase by the same number next year
percent increase = 675 - 597 / 675 = 78 / 675 = 0.12 = 12%
Here, the <em>standard deviation </em>is the best measure of the spread of a data set. The higher the standard deviation, the more spread out the distribution is. In this case, the distribution with the highest standard deviation (and therefore the greatest spread) is Distribution 3. Its low mean might be deceptive, but the value of a data set's mean has no effect on its spread.
So you divide by 2 because there is 2 buildings. You get 760. Now, just take 200 away from one building, and 200 away from the other, and you get 560 for Building A, and 960 from Building B.
Answer:
21.25 m
Step-by-step explanation:
y = Ax² + Bx + C
Set the origin at the middle of the span so that the point (0, 0) is on the curve
0 = A(0)² + B(0) + C means C = 0
The points (200, 85) and (-200, 85) are on the curve
85 = A(200)² + B(200)
85 = A(-200)² + B(-200)
85 - 40000A - B(200) = 85 - 40000A + B(200)
- B(200) = B(200)
-400B = 0
B = 0
85 = A(200)²
A = 85/40000
y = 85x²/40000
y = 85(100)²/40000 = 21.25 m
