Question 15 -

SOLUTION:

Let's establish the formula for the gradient / slope of a line as follows:

Slope = ( y2 - y1 ) / ( x2 - x1 )

Now we will simply substitute the values from the problem into the gradient / slope formula in order to obtain the value of ( y ).

x1 = 5

x2 = - 7

y1 = 2

y2 = y = ?

Slope = ( y2 - y1 ) / ( x2 - x1 )

5 / 6 = [ ( y ) - ( 2 ) ] / [ ( 5 ) - ( - 7 ) ]

5 / 6 = ( y - 2 ) / ( 5 + 7 )

5 / 6 = ( y - 2 ) / 12

( y - 2 ) / 12 = 5 / 6

y - 2 = ( 5 / 6 ) × 12

y - 2 = 60 / 6

y - 2 = 10

y = 10 + 2

y = 12

FINAL ANSWER:

Therefore, the answer is:

y = 12

Hope this helps! :)

Step-by-step explanation:

A Chi-square test is used to test the test of independence between rows and columns, contingency tables. It is a test related to frequencies. The observed frequency is a given statistical frequency known as the actual frequency,  the expected frequency is known as the theoretical frequency is derived from the study by using the sum total of the row and total in the column divided by their corresponding sample size.
