Answer:
(x + 1)/4x² + 4(x + 1)/4x²
Step-by-step explanation:
x+1/4x² + x+1/x²
The above can be simply as follow:
Find the least common multiple (LCM) of 4x² and x². The result is 4x²
Now Divide the LCM by the denominator of each term and multiply the result with the numerator as show below:
(4x² ÷ 4x²) × (x + 1) = x + 1
(4x² ÷ x²) × (x + 1) = 4(x + 1)
x+1/4x² + x+1/x² = [(x + 1) + 4(x + 1)]/ 4x²
= (x + 1)/4x² + 4(x + 1)/4x²
Therefore,
x+1/4x² + x+1/x² = (x + 1)/4x² + 4(x + 1)/4x²
Answer:
The binomial probability formula can not be used for this experiment because it does not state the number of times he expects to draw his favorite suit.
Step-by-step explanation:
The binomial probability formula is expressed as follows:
P (k success in n trials) =


n = number of trials, k = number of successes, n-k = number of failures, p = probability of success in one trial and q = 1 - p = probability of failure in one trial.
In the given problem, all of the variables are known except for 'k', the amount of times that the student predicts he will draw his favorite suit.
V = (4/3)×3.14×(1.5^3)
V = 14.1 in^3
Answer:
y = 
Step-by-step explanation:
given that y varies inversely with x then the equation relating them is
y =
← k is the constant of variation
To find k use the condition x = 2 when y = 11
k = yx = 11 × 2 = 22
y =
← equation of variation
