for A you should take each plotted point and change the sign of the x values. for example (-1,3) should become (1,3) and (-4,4) should become (4,4)
for B take each point and flip the variables and x's sign. (-1,3) should become (3,1)
for C take every x value and subtract 2. (-1,3) should become (-3,3)
for D take each point and flip the variables and y's sign. (-1,3) should become (-3,-1)
It would be biased because one would assume that students can get to school by means other than those that put them 8n the parking lor. (Parking lot = car drivers who would be the only students sampled.). Others may ride to school by either parent or school bus who could drop them off somewhere else or possibly walk to school. The freshmen/sophomores would be excluded generally as they would be too young to drive altogether
Answer:
6 ft
Step-by-step explanation:
The surface area of a cube is given by
SA = 6s^2
216 = 6s^2
Divide each side by 6
216/6 = 6s^2/6
36 = s^2
Take the square root of each side
sqrt(36) = sqrt(s^2)
6 =s
Each side is 6ft
22.4
If the bottom side is 20 cm, then each line BE and CE would each be 10 cm.
Now, just focus on the top left triangle. You have one side with 20 cm, and the other side with 10 cm. You are left with the hypotenuse, which you need to figure out the value of.
Since this is a right triangle, you can use the Pythagorean theorem -> a^2 + b^2 = c^2 where c is the hypotenuse.
20^2 + 10^2 = c^2
400 + 100 = c^2
500 = c^2
22.36 = c
