Answer:
Given:
mu = 200 lb, the mean sigma = 25 the standard deviation
For the random variable x = 250 lb, the
z-score is z = (x - mu) / sigma = (250 - 200) / 25 = 2
From standard tables for the normal distribution, obtain
P(x < 250) = 0.977
Answer: 0.977
Answer:
always b is equal to 9 is rhdx forum post in is ek of
X is interesting with b
Hope this helps:D
Start by isolating the variable on one side by adding 43w^2 to both sides. The equation will read:
25w^2+5=0
<em>*Subtract 5 from both sides*</em>
25w^2=-5
<em>*Divide both sides by 25*</em>
w^2=-1/5
<em>*Take the square root of both sides*</em>
w=√(-1/5)
The square root of -1 is i. The square root of 5 remains √5
The answer is i/√5.
Hope this helps!!
