Snezhnost [94]2 years ago

Answer:

y = 6.5

Step-by-step explanation:

     When triangles are similar, we can set up a proportion to compare the sides. I will have the "left" side on the bottom of the fractions, and the side I am solving for on the top.

 \frac{y}{6} =\frac{13}{12}

[Cross multiply]

12y = 78

y = 6.5

Have a nice day!

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly.

miss Akunina [59]

Answer:

The question is unclear and incomplete.

Let me explain the degrees of freedom in statistics.

Step-by-step explanation:

Statistically, degrees of freedom which is denoted as DF is the number of independent values that can vary in an analysis without breaking any constraints. It can also be referred to as the number of independent values that a statistical analysis can estimate.

Degrees of freedom also define the probability distributions for the test statistics of various hypothesis tests.

The degree of freedom has the formula:

DF = N - 1 where N number of random variables

DF = (R - 1) x (C - 1) Where R is the number of data values and C is the number of groups

a tea company surveyed shoppers at two different malls. shoppers were asked whether they prefer sweetened or unsweetened tea. at
FromTheMoon [43]
First, let's create the ratios of sweetened to unsweetened. To do this, you would have to subtract the number of people that preferred unsweetened from the total.
Westside mall: 15:30 or \frac{15}{30}
Eastside mall: 13:26 or \frac{13}{26}

Now, you would divide to both ratios.
15 ÷ 30 = 0.5
13 ÷ 26 = 0.5 

They have the same sum, meaning, they are the same. 

Westside Mall shoppers are just as likely to prefer unsweetened tea as Eastside Mall shoppers. 

I hope this helps!
