Answer: D) a V shaped graph with vertex at(2,4) which opens up
Step-by-step explanation:
Answer:
The standard error of the mean is 10.11 points
Step-by-step explanation:
Standard error of mean = t×sd/√n
sd = 115 points, n = 500, degree of freedom = n-1 = 500-1 = 499, assuming a 95% confidence level, t-value corresponding to 499 degrees of freedom and 95% confidence level is 1.96501
Standard error of mean = 1.96501×115/√500 = 10.11 points (to the nearest 100th)
Answer:
24feet 1 inches
Step-by-step explanation:
Answer:
If the perimeter is 200feet (two lengths and two widths) then one width+one length equals 100feet.
If the length is 10 feet longer than the width, then length = 55 feet, and width =45 feet
Therefore the area of the rectangle is 45x55 feet, which equals 2475 sq.ft
