Answer:

The number of people needed is $n =684$

Step-by-step explanation:

From the question we are told that

The population proportion is $p = 0.65$

The margin of error is $E = 0.03$

From the question we are told the confidence level is 90% , hence the level of significance is

$\alpha = (100 - 90 ) \%$

=> $\alpha = 0.10$

Generally from the normal distribution table the critical value of $\frac{\alpha }{2}$ is

$Z_{\frac{\alpha }{2} } = 1.645$

Generally the sample size is mathematically represented as

$n =[ \frac{Z_{\frac{\alpha }{2} }}{E} ]^2 * p(1-p)$

=> $n =[ \frac{1.645 }{0.03} ]^2 * 0.65(1-0.65)$

=> $n =684$

Can anyone help me out? thanks

Alik [6]

Answer:

450 cm

Step-by-step explanation:

12 degrees is 1/30 of the circumference because there are 360 degrees in a circle.

The minor arc length of 15 is in the same ratio to the circumference as the 2 angles , so the circumference = 30 * 15 - 450 cm.

Tysm for the help! <3

By using the given graph:

When x = -2, the value of the function is f(-2) = 1
When x = -0.5, the value of the function is f(-0.5) = 0.75
When x = 0, the value of the function is f(0) = 1.25
When x = 2.5, the value of the function is f(2.5) = 3
When x = 6, the value of the function is f(6) = 0

<h3></h3><h3>How to use the graph to find the values of the function?</h3>

Suppose that we want to find the value of the graphed function when x = a.

Then we first need to identify x = a in the horizontal axis.
Then we move upwards (or downwards) until we meet the curve of the function.
Now you can move horizontally towards the vertical axis, where you can read the y-value associated to the x-value.

Now we can do these steps for each of the wanted values.

When x = -2, the value of the function is f(-2) = 1
When x = -0.5, the value of the function is f(-0.5) = 0.75
When x = 0, the value of the function is f(0) = 1.25
When x = 2.5, the value of the function is f(2.5) = 3
When x = 6, the value of the function is f(6) = 0
