Answer:
16 square inches
Step-by-step explanation:
1/2*4*8
We are given three vertices, but we do not know which two are adjacent. We could draw these points to find out. But that is not neccesary.
In a parallelogram we can draw four types of lines. Two types are sides and two types are diagonals. Diagonals are lngre than sides. This helps us to solve this problems. If we find distance between all points we will take only two smaller numbers because they represent sides.
Distance between two points is given by:
For points (3,2) and (4,4) distance is:
For points (3,2) and (6,1) distance is:
For points (4,4) and (6,1) distance is:
Last distance is greatest and it represents a diagonal. Other two distances represent sides.
Perimeter of a parallelogram is given by:
Answer:
LP = 16 units (8 + 8)
x = 4.25 units

Answer: a) 1683
<u>Step-by-step explanation:</u>
First, let's find the z-score using the formula:
Next, refer to the z-score table below to find the value of 1.00
Look on the left side for 1.0 and the top for 0.00 to find the percent for 1.00. The table shows the percent above the MEAN so you need to add the percent below the mean (50%) to the value in the table.
0.3413
<u>+ 0.5 </u>
0.8413
Now multiply that percent by the total number (2000) of girls to find out the quantity of girls who are 51 cm or shorter.
0.8413
<u>× 2000</u>
1682.6
