Answer:
We have sufficient evidence to conclude at α = .05 that the husband’s perception would be higher than the wife’s.
Step-by-step explanation:
The hypotheses testing procedure in the given scenario is
H0: Husband’s perception would be similar to the wife’s i.e. μh=μw
Ha: Husband’s perception would be higher than the wife’s i.e. μh>μw
Level of significance: α=0.05
Test statistic: t=2.776
Critical region: t>t(0.05,9)=1.833
Conclusion: As the calculated value of t lies in critical region, so we reject our null hypothesis at 0.05 level of significance. Thus, we have sufficient evidence to conclude at α = .05 that the husband’s perception would be higher than the wife’s.
7 ig because I mean if you take a look at the problem
For this case we have by definition, that the equation of a line in the slope-intersection form is given by:

Where:
m: It is the slope of the line
b: It is the cut point with the "y" axis
We have, according to the data provided, that the line is of the form:

That means that the slope is -1.
ANswer:

Answer: B, Each of the sums is 180 degrees.
Step-by-step explanation:
Since a 180 degree angle is always a flat line, and that is the case for this,
Each of the sums is 180 degrees.
I think it’s d because that’s where the z would come from with the AEC right angle.
