Step-by-step explanation:
I used a calculator but the answer is 1 1/6
Answer:
Step-by-step explanation:
1a = yes
1b = no, you don’t add the denominators together when adding.
1c = yes
1d = yes
Given:
μ = 89 ng/ml, population mean
σ = 23 ng/ml, population standard deviation
Random variable, x = 100
To test P(x < 100), calculate the z-score.
z = (x-μ)/σ = (100 - 89)/23 = 0.4783
From standard tables, obtain
P(x < 100) = 0.6838 = 68.4%
Answer: 68.4%
Answer: (x+5)(x-3)2 = 0
Step-by-step explanation: To write this equation as a polynomial, you must multiply it out.
begin by squaring the binomial, and remember to express this as a trinomial (middle term will be -6x).
Then, to finish the job, multiply that trinomial by the factor x+5. Hope this will help you.
