An electrical pole breaks at a height of 6m from its base due to a thunderstorm. Its top touches the ground at a distance of 8m

from the base of the pole to form a right angled triangle. Find the height of the pole.

16m because if you use the pythagorean therum the rest of the pole is 10m long, which you add to the base of the pole.

Suppose a simple random sample of size n = 1000 is obtained from a population whose size is N = 2,000,000 and whose population p
faltersainse [42]

Answer:

p(x\geq 520)  = 0.0293

Step-by-step explanation:

Given data:

random sample size n = 1000

Population size is N - 2,000,000

P = 0.49

We know

\sigma_p = \sqrt{\frac{p*(1-p)}{n}}

\sigma_ p = \sqrt{\frac{0.49*(1-0.49)}{1000}} = 0.0158

Probability for having X =520

sample proportion \hat p = \frac{520}{1000} = 0.52

p(x\geq 520)  = P(\hat p\geq)

                       = P(Z\geq \frac{0.52 - 0.49}{0.0158})

                       = P(Z\geq 1.89) = 0.0293

p(x\geq 520)  = 0.0293

The graph of y = f(x) is shown. <br> a) Find f(0) <br> 4- <br> 3. <br> b) Give the roots of f(x) = 0
Amanda [17]

The value of f(0) is 1

and

The roots of f(x) = 0 are -2 and -1

<h3>Graph of a function</h3>

From the question, we are to determine the value of f(0) and the roots of f(x) = 0

The value of f(0) is the value of f(x) or the value of y when x = 0

In the given graph, we can observe that the value of y when x = 0 is 2

∴ f(0) = 2

The roots of f(x) = 0 correspond to the values of x when f(x) = 0 or when y = 0

In the graph, we can observe that the values of x when f(x) = 0 are -2 and -1

∴ The roots of f(x) = 0 are -2 and -1

Hence, the value of f(0) is 1

and

The roots of f(x) = 0 are -2 and -1
