8 0

The ranking of best beers at the Portland Brewfest in a natural and ordered manner is an example of an ordinal scale.

Ordinal scale of measurement is the second level of measurement that defines a variable.

Ordinal scale shows order and ranking between variables that are being defined.

The ranking of best beers is simply natural and ordered into categories. This shows magnitude and rank among variables. This makes it an example of ordinal scale.

Therefore, the ranking of best beers at the Portland Brewfest in a natural and ordered manner is an example of an ordinal scale.

alisha [4.7K]

Answer:

a) For this case we define the random variable as X ="waiting time during peak hours" and we know that this distribution follows an uniform distribution:

$X \sim Unif(a=0,b=8)$

Where a and b represent the limits of the distribution.

b) $f(x) = \frac{1}{8}= 0.125, a\leq x \leq b$

And the height for this case would be 0.125

Step-by-step explanation:

Part a

For this case we define the random variable as X ="waiting time during peak hours" and we know that this distribution follows an uniform distribution:

$X \sim Unif(a=0,b=8)$

Where a and b represent the limits of the distribution.

Part b

For this case the density function would be given by:

$f(x) = \frac{1}{8}= 0.125, a\leq x \leq b$

And the height for this case would be 0.125

And $f(x)= 0$ for other case.

The cumulative distribution function would be given by:

$F(x) = 0, x$

$F(x) = \frac{x-a}{b-a}= \frac{x}{8}, 0\leq x < 8$

$F(x) = 1, x\geq 8$

John kept track of how many baskets were made in a basketball game. After 4 minutes, 5 baskets were made.

ivann1987 [24]

1 basket is between 9 and 10 minutes .

Step-by-step explanation:

Here we have , John kept track of how many baskets were made in a basketball game. After 4 minutes, 5 baskets were made. We need to find How many baskets were made between 9 and 10 minutes . Let's find out:

In order to calculate baskets between 9 min and 10 min we will find baskets at 10 min and at at 9 min , will subtract than !

Baskets at 10 min :

At 4 min we have 5 baskets so , in 10 min

⇒ $(10)\frac{5}{4}$

⇒ $1.25(10)$

⇒ $12.5$

Baskets at 9 min :

At 4 min we have 5 baskets so , in 9 min

⇒ $(9)\frac{5}{4}$

⇒ $1.25(9)$

⇒ $11.25$

So , Baskets between 10 & 9 min is $12.5-11.25=1.25$ , which on rounding off gives 1 . Therefore , 1 basket is between 9 and 10 minutes .

Solve this quadratic equation by completing the square.

nadya68 [22]

Answer:

$x=-3+\sqrt{27}\\ x=-3-\sqrt{27}$

Step-by-step explanation:

Let's find our C value for the quadratic equation.

$(\frac{6}{2})^{2} = 9$

That is our C. Since we added 9 to one side, we have to do the same to the other. We get:

$x^{2} +6x + 9 = 18 + 9\\x^{2} +6x + 9 = 27$

Now, lets form the left side as a binomial squared.

$(x+3)^{2} = 27$

Let's square both sides now:

$x+3 = (+/-)\sqrt{27}$

Now, we subtract 3 from both sides to isolate the variable, X:

$x= -3(+/-)\sqrt{27}$

This means that the answers are:

$x=-3+\sqrt{27}\\ x=-3-\sqrt{27}$

I do not understand your answers though. Answer A makes no sense, answer B is 221, answer C is 115, and answer D also does not make sense. If you could clarify this portion, maybe I can help you find your alphabetic answer
