Answer:
89
Step-by-step explanation:
7^2=49
49+4=53
6^2=36
53+36=89
Answer:
c) is true
Step-by-step explanation:
Given are four statements. Let us check one by one
a) If the calculated value of F statistic is higher than the critical value, we reject the alternative hypothesis in favor of the null hypothesis
False, we reject H0 in favour or alternate
b) The F statistic is always nonnegative as SSRr is never smaller than SSRur.
F statistics is non negative but reason is bot SSRr and SSRur are positive
Not because SSRr is never smaller than SSRur
c) Degrees of freedom of a restricted model is always less than the degrees of freedom of an unrestricted model.
This is true because in a restricted we put constraints thus df will be less
d) The F statistic is more flexible than the t statistic to test a hypothesis with a single restriction.
False. F statistic is for testing variances while t statistic for means.
Answer:
D
Step-by-step explanation:
Well all triangles have an area of 180 degrees, therefore X=39 because 102+39=141 and 180-141=39.
Answer:
The value of x is -125
Therefore x=-125
Step-by-step explanation:
Given that the expression is 
To solve the expression :
( by using the property 
)
( expanding the power )
Let 
Now the value of x is
Therefore x=-125
The value of x is -125
