Perimeter=4h+4
If the base is 2 more than the height, it gives us the equation:
b=h+2
The equation for the perimeter of a rectangle can be though of as 2b+2h, so substituting in (h+2) for b from the first equation, we get 2(h+2)+2h.
This can be simplified to be 2h+4+2h or 4h+4
Answer:
Step-by-step explanation:
The slope of the graph at x=0 is related to the value of b. It is also proportional to the value of <em>a</em>, which is the same for all but curve B. The red curve R has the largest slope at x=0, (much larger than 3/4 the slope of curve B), so curve R has the greatest value of <em>b</em>.
Similarly, the smallest value of <em>b</em> will correspond to the curve with the smallest (most negative) slope. That would be curve K. Curve K has the smallest value of <em>b</em>.
Answer:
B. Married, widowed, or divorced men have high income jobs. A high income job tends to make an individual more dedicated. This dedication leads a man to get married.
Step-by-step explanation:
A lurking variable is one that is not measured in the given study but it will affect the relationship between the explanatory and response variables.
Now, in this case, we see that divorced or widowed men, are said to earn quite a little more than men that are of the same age who have never been married.
Now, we are told it does not imply that a man can raise his income by getting married.
This means that majority who have high income tend to consider getting married.
Thus, we can infer that having a high income job leads to a man being more dedicated and this leads him to getting married.
