Answer:
The answer is explained below
Step-by-step explanation:
We have the following formulas:
from binomial distibution: P (X = x) = (nCx) * (p) x * (1-p) n-x
from normal distribution: P (X <= x) = (x-np) / sqrT (np (1-p))
Now, n = 25 and p (0.5, 0.6, 0.8), we replace in the formulas and we are left with the following table:
P P(15<=X<=20) P(14.5<=X<=20.5)
0.5 0.2117 is less than 0.2112
0.6 0.5763 is less than 0.5685
0.8 0.5738 is greater than 0.5957
Answer:
25x^6 is the right answer
Step-by-step explanation:
Answer:
-7y+8x
Step-by-step explanation:
-2y-x-5y+9x
The mid-line for f(x) = 4cos x is y = 0. In the given equation, the term -2 is described as the y-shift. Therefore the mid-line for f(x) = -2 + 4cos x is:
y = -2.
Answer:
4:1
Step-by-step explanation:
If the side length x is dilated to 2x, the area x² will dilate to (2x)² = 4x², which is 4 times the original x².
