For this case we have that by definition, the area of the trapezoid is given by:
Where:
B: It is the major base
b: It is the minor base
h: It's the height
Substituting the values according to the data of the figure:
Thus, the area of the trapezoid is

Option B
Answer:
Mean = 11.8
Median = 11
Step-by-step explanation:
Here we are asked to calculate the median and the mean for these set of numbers
Let’s start with the mean
The mean refers to the average, we simply add all the numbers together and divide by their count.
That would be;
Arithmetic mean = (10+ 5 + 18 + 9 + 17 + 12)/6 = 71/6 = 11.833 which is 11.8 to the nearest tenth
To get the median, what we do is to first rearrange the values we have from the lower to the highest.
That would be;
5,9,10,12,,17,18
Looking at the numbers after rearranging, the two middle numbers we have are 10 and 12.
So we add these together divide by 2.
That would be (10+12)/2 = 22/2 = 11
Answer:
Step-by-step explanation:
Although you didn't finish the question Im assuming you want to know how much she'd get paid now. So you would do 500x.2=100 and would add that to her current pay. So she would be making 600 dollars a week
Answer:
(C) 10 units
Step-by-step explanation:
It is given that EFGH is a rhombus and EG = 16 and FH = 12.
We know that the diagonals of the rhombus are the perpendicular bisectors, therefore OF=6, OH=6, OE=8 and OG=8.
Now, using the Pythagoras theorem in ΔOFG, we have
Thus, the value of the side of the rhombus will be 10 units.
Hence, option C is correct.
