Given:
The equation is:
To find:
The number that should be added to sides of the equation to complete the square.
Solution:
If an expression is in the form of , then we have to add to make it perfect square.
We have,
...(i)
To make it perfect square we need to add square of half of coefficient of x on both sides.
Coefficient of x is -10, so square of half of coefficient of x is:
On adding 25 on both sides of (i), we get
Therefore, we need to add 25 to both sides of the equation to complete the square.
Answer:
0.2425 or 24.25%
Step-by-step explanation:
If the shipment of 400 components contains 68 defective and, we can estimate the probability of selecting a defective components as
68/400 = 0.17
Now, we have a binomial experiment of 25 trials and we want to compute the probability that more than 5 trials are “success” (defective component)
P(X>5) = 1 - P(X≤ 5)
Since
<em>1 - P(X≤ 5) = 1 - (P(X=0) + P(X=1) + P(X=3) + P(X=4) + P(X=5)</em> =
Answer:
-8/3
Step-by-step explanation:
We can find the slope of the line using two points
(1,4) and (4,-4)
m = (y2-y1)/(x2-x1)
= (-4-4)/(4-1)
= -8/3
