Answer:
x=-17.......................
Step-by-step explanation:
x+17=0
17^2 because the equation for it is a^2+b^2=c^2 so the longest side (x) is the c so 10 i put as a and 7 i put as b. it will always be squared for pythagorean theorem so the equation will look like 10^2+7^2=17^2 and if it isn’t squared all you have to do is undo the squaring
Given : If x ≠ -2 then f(x) = 
As -5 ≠ -2 ⇒ f(-5) = 
Given : if x = -2 then f(x) = -1
As x = -2 ⇒ f(-2) = -1
Given : If x ≠ -2 then f(x) =
As 2 ≠ -2 ⇒ f(2) = 
How do you find the expected frequency in a chi square goodness of fit?
Pearson's chi-square goodness of fit test statistic is: - where Oj are observed counts, Ej are corresponding expected count and c is the number of classes for which counts/frequencies are being analysed.
