Can someone help me with #10 please
2 answers:
X=11 because 90-43+5x-8 so 5•11=55-8 =47 90-43=47
Complementary means the angles together would equal 90°. Supplementary means the angles would equal 180°.
Using Complementary angles:
5x-8+43=90 Combine -8 and 43 = 35
5x+35=90
-35 -35
5x=55
Divide each side by five
x=11

Answer:
mean= 4.68
variance= 1.0296
Step-by-step explanation:
mean= n×p
n=6
p=0.78
mean= 6×(0.78)
= 4.68
variance= n×p×(1-p)
= 6 × 0.78×(1-0.78)
= 1.0296
