Answer:
x = 69
Step-by-step explanation:
For this data set:
Mean: (3+3+4+4+4+5+5+5+5+30) : 10 = 6.8
Mode : 5
Median : (4+5) : 2 =4.5
In this case, the mean is not the best way to show central tendency.
The median is less affected by outliers and skewed data.
Answer: The best measure for the central tendency is the median: 4.5
Answer:
x = 6 or x = -2
Step-by-step explanation:
Solve for x:
2 x^2 - 8 x - 24 = 0
The left hand side factors into a product with three terms:
2 (x - 6) (x + 2) = 0
Divide both sides by 2:
(x - 6) (x + 2) = 0
Split into two equations:
x - 6 = 0 or x + 2 = 0
Add 6 to both sides:
x = 6 or x + 2 = 0
Subtract 2 from both sides:
Answer: x = 6 or x = -2
Answer:
a=76 b=83
Step-by-step explanation:
for a. we divide 6688(area) by 88 to find the width bc 88*w=6688
6688/88 is 76 so a=76
Since 312 is perimeter we have to subtract 73 twice and then divide that by 2 bc 73+73+L+L=312
(312-73-73)/2=83 so b=83
