Answer:
<u>The correct answer is D. ∛ 16</u>
Step-by-step explanation:
The set of irrational numbers is formed by all the decimal numbers whose decimal part has infinite periodic figures, that is, by all those numbers that cannot be represented by the quotient of two integers. The most known irrational number is π = 3.14159265.....
A.√100 = 10 is not an irrational number.
B. 1/8 = 0.125 is not an irrational number.
C. - 2.2675 = - 2 107/400 is not an irrational number.
Answer:
Standard error = 0.028
Step-by-step explanation:
Standard error of the mean = √x(N-x)/N3 = 0.028
Standard error is 0.028
If you need further answer, see below
α = (1-CL)/2 = 0.025
Standard normal deviate for α = Zα = 1.960
Proportion of positive results = P = x/N = 0.720
Lower bound = P - (Zα*SEM) = 0.664
Upper bound = P + (Zα*SEM) = 0.776
95% Confidence interval is 0.664 to 0.776
Answer:
The answer is 4.
Step-by-step explanation:
In order to get this answer you have to use inverse operations. The inverse operation for multiplication is always division. So, you have to solve the equation 7.5 ÷ 1.75. When getting the answer to that (the answer of the equation above), you get <em>n</em>, as it is only a one-step equation. I hope I could help you.
X should be around 1.5625, assuming that -4 is squared is not in a parenthesis. So, the problem should be -20=-4^2(sqrtx). Divide -20 by -16 to get 1.25. Then square 1.25 and sqrt x to get 1.5625.
I know my math and your answer is going to be A.
