Increasing the sample size by a factor of 4 or multiplying
it by 4 is equal to increasing the standard error by 1/2. Therefore, the
interval will be half as varied. This also works almost for population
averages as lengthy as the multiplier from the t-curve doesn't modify much when
increasing the sample size.
Answer:
c=2
Step-by-step explanation:
(4x^2 y^2 + 8x^3 y^5) / (2x y^2) = 4x^2 y^2 / 2x y^2 + 8x^3 y^5 / 2x y^2 = 2x + 4x^2 y^3
Therefore, a = 1, b = 0, c = 2 and d = 3
Answer:
goodluck
Step-by-step explanation:
U need to find the length
7 + 7 + 18 + 18 = 50
width is 7 and length is 18
area is length x width
18 x 7 = 126 ft^2
Use the quadratic formula -b+/-√b^2 -4(ac) / 2a
-4 +/- √(4^2 - 4(1*10) / (2*1)
X = -2 +/- i√6
