Answer with explanation:
Given : The computed r -value = 0.45
Sample size : n=18
Degree of freedom : 
Now, the critical value for Pearson correlation coefficient for a two-tailed test at a .05 level of significance will be :
( by critical correlation coefficient table)
Since , 
i.e. 0.45>0.468 , then we say that his Pearson correlation coefficient is not significant for a two-tailed test at a .05 level of significance.
We use the simple rules of statistics to accept the null hypothesis
68% of the data falls within 1 sd of the mean95% of the data falls within 2 sd of the mean 99% of the data falls within 3 sd of the mean
20 falls between the range of -56 to 56 (from the given 95% c.i.), hence we accept the null hypothesis; else, if the mean falls outside the range, we reject the null hypothesis.
Answer:
Step-by-step explanation:
Quadratic function is function of the form 
where a, b and c are real numbers and 
A number is said to be a rational number if it can be written in the form 
where u and v are integers and 
.
A number is said to be a complex number if it can be written in the form u+iv where u and v are real numbers.
A number 'a' is said to be a zero of a function P(x) if 
We know that if zero of a fraction is of form u+iv then its other zero is u-iv.
As 3+7i is a zero of the function, 3-7i is also its zero.
So, given equation is 
Answer: 7/16

i got it right
Hello there,
So. . .The word reciprocal mean's the opposite. So we are going to flip the expression all around.So the reciprocal of
is the following:
Hope this helps.
