Use the algebraic procedure explained in section 8.9 in your book to find the derivative of f(x)=1/x. Use h for the small number

Triss [41]

Answer:

By definition, the derivative of f(x) is

$lim_{h\rightarrow 0}\frac{f(x+h)-f(x)}{h}$

Let's use the definition for $f(x)=\frac{1}{x}$

$lim_{h\rightarrow 0} \frac{\frac{1}{x+h}-\frac{1}{x}}{h}=\\lim_{h\rightarrow 0} \frac{\frac{x-(x+h)}{x(x+h)}}{h}=\\lim_{h\rightarrow 0} \frac{\frac{(-1)h}{x^2+xh}}{h}=\\lim_{h\rightarrow 0} \frac{(-1)h}{h(x^2+xh)}=\\lim_{h\rightarrow 0} \frac{-1}{x^2+xh)}=\frac{-1}{x^2+x*0}=\frac{-1}{x^2}$

Then, $f'(x)=\frac{-1}{x^2}$

Suppose we select a simple random sample of size n=250 from a large population with a proportion p of successes. Let p be the pr

Tom [10]

Answer:

B.0.15

Step-by-step explanation:

To approximate a binomial distribution as a normal distribution, two conditions must be met:

np > 10

nq = n (1−p) > 10

Here, n = 250. Check each value of p to see if it meets the conditions.

A. p = 0.03

np = 7.5, nq = 242.5

B. p = 0.15

np = 37.5, nq = 212.5

C. p = 0.02

np = 5, nq = 245

D. p = 0.97

np = 242.5, nq = 7.5

E. p = 0.99

np = 247.5, nq = 2.5

Of the five choices, only B meets both conditions.
