To find the mean, you have to add all the numbers then divide it by how many numbers there are.
In this case, you'll need to add all those numbers and divide it by 4.

The mean is 1995.
T= sqrt(5/wc)
remove ( )
T= 5sqrt/wc
multiply by wc
Twc=5sqrt
divide by Tc
W= 5sqrt/cT
hope this helps
Answer: -3
mark me brainiest very easy answer
Answer:
C. Yes, we can prove the triangles congruent by SAS.
Step-by-step explanation:
In ∆ABC and ∆DEF,
BC = EF = 6 cm
angle A = angle D = 22°
AC = DF = 14 cm
Hence, the triangles are congruent.
( by SAS congruency criterion )
10^0 is 1. 1 time 17.55 is 17.55
