Answer:

The value of x is 148
The best point estimate of population proportion is 74%

Step-by-step explanation:

Sample size = n = 200

Number of employees who prefer the new coffee = 148

The formula to calculate the point estimate is:

$p=\frac{x}{n}$

Here, x is the number of outcomes of our interest i.e. the number of employees who prefer the new coffee brand over the old one. Therefore,

x = 148

Using the values in the above formula, we get the point estimate as:

$p=\frac{148}{200} \\\\ p=0.74\\\\ p =74\%$

Therefore, the best point estimate for the population proportion is p = 74%

So, the correct statements for this scenario are:

The value of x is 148
The best point estimate of population proportion is 74%

A bag contains 8 blue marbles, 6 green marbles, 12 yellow marbles, and 10 orange marbles. A marble is drawn at random from the b

Olenka [21]

Probability of anything =

   (number of possible successful outcomes)
divided by
   (total possible number of outcomes) .

There are 36 total marbles in the bag, so there are 36 total
possible outcomes of one draw.

The successful outcomes are all the possible draws that are
not blue. There are 28 of those.

So the probability of a non-blue selection is

   28/36 = 7/9 = 77.8% (rounded)

A terminal ray passes through (12,-5). Fine the value to all six trig functions

Harman [31]

Okay, here we have this:

Considering the provided angle, we are going to calculate the requested trigonometric functions, so we obtain the following:

So the first thing we will do is calculate the length of the hypotenuse, that is, the distance between the given point and the origin, then we have:

$\begin{gathered} r=\sqrt{(12-0)^2+(-5-0)^2} \\ r=\sqrt{12^2+(-5)^2} \\ r=\sqrt{144+25} \\ r=\sqrt{169} \\ r=13 \end{gathered}$

Now we proceed to find the value of each ratio:

$sin\beta=\frac{y}{r}=\frac{-5}{13}$ $cos\beta=\frac{x}{r}=\frac{12}{13}$ $tan\beta=\frac{y}{x}=\frac{-5}{12}$ $csc\beta=\frac{r}{y}=\frac{13}{-5}=-\frac{13}{5}$ $sec\beta=\frac{r}{x}=\frac{13}{12}$ $cot\beta=\frac{x}{y}=\frac{12}{-5}=-\frac{12}{5}$
