Answer:
(x1 + x4)/2 = 4
Step-by-step explanation:
(x1 + x2+ x3 + x4)/4 = 5 mean
x1 , x2 , x3 , x4
median (x2+x3)/2 = 6
(x2+x3) = 12
The smallest integer is x1, the largest integer x2.
The mean of the largest and smallest of the integers is (x1 + x2)/2.
(x1 + x2+ x3 + x4)/4 = 5
x1 + x2+ x3 + x4 = 20
x1 + 12 + x4 = 20
x1 + x4 = 20 - 12
x1 + x4 = 8
(x1 + x4)/2 = 8/2
(x1 + x4)/2 = 4
Yes because they both give you an x =2 and a y=-4
5)
you got it right
2 sides are congruent
6)
2 angles are congruent (each = 45)
8)
the triangle in #8 has been cut off. (is it a right triangle? if so, then there are 2 acute angles)
----------------------------
BTW, # 7 , measure of each angle = 60 (3 congruent angles)
Answer:
1/1296
Step-by-step explanation:
P( 5) = number of 5's over total numbers possible
= 1/6
P( 5,5,5,5) = 1/6 * 1/6 * 1/6* 1/6
=1/1296
