Answer:
15 feets
Step-by-step explanation:
The perimeter of a parallelogram is given as :
P = 2(l + w)
l and w are the bases :
Substituting the values into the equation :
P = 2(x + 75 + x + 45)
P = 2(2x + 120)
P = 300
Hence ;
300 = 4x + 240
300 - 240 = 4x
60 = 4x
Divide both sides by 4 to isolate x
60 /4 = 4x / 4
15 = x
x = 15 feets

Answer:
Median
Step-by-step explanation:
Since the data has an outlier (12,985), mean is not the best average.
This data set does not have a modal value
Therefore the best option is Median
Answer: The range is [3, infinity).
Step-by-step explanation: The "[" means that it is apart of the graph. The ")" means it is not apart of the graph.
The graph's range (which is it's highest lowest to highest y-value), the lowest is 3 on the y axis, and then stems on to infinity. The reason why infinity is not apart of the graph is because it has no end and infinity is not a number.
½(x+10) = ¼(x+54)
Solving it
x/2 + 5 = x/4 + 13.5
x/2 - x/4 = 13.5 - 5
x/4 = 8.5
x = 8.5 × 4 = 34
