Answer:
EF is 4 units.
Step-by-step explanation:
It is given that the two triangles 
are congruent to each other i.e.
Coordinates are given as:
A(-1,1)
B(2,4)
C(3,1)
As per the property of congruence, all the corresponding sides and angles of the two triangles are equal to each other.
i.e. AB = ED
BC = DF
AC = EF
We are given with the coordinates of points A, B and C here from which we can easily calculate the side AC using the distance formula.
Where 
are the coordinates of the two points whose distance is to be calculated.
So,
Hence, <em>AC = EF = 4 units</em>
Answer with Explanation:
Average in Temperature in last 30 years in the month of July for Eloy and Arizona=90°
Standard Deviation =2.1°
→It means ,temperature of last 30 years of states Eloy and Arizona lie between , 90°-2.1° to 90°+2.1°= 87.9° to 90°.
→→Average of last five Summers, for Eloy and Arizona=92°
a=2.5%
Calculating , the reduction ,which is equal to 2.5% from 92
→89.70° lies between ,87.9° to 90°.
So,we can confidently assert that→the two averages are probably same.
Option D: The average for the last five years fits with the 30-year average.
So 3 pies with 8 pcs each.
8 x 3 = 24
3/4 of 24 is 18
the awnser is 18
Idk lol... srry couldn't help
