Answer:
29+31+24+30+20+18+16= 168
how many numbers there are= 7
168/7= 1,176
The mean is= 1,176
Hope this helped

Answer:
B.
Step-by-step explanation:
Volume of the model of moon = 4/3(πr³)
= 4/3(π)(1)³
= 4.2 feet³
Volume of cylinder = πr²h
= (3.14)(0.5)²(0.5)
= 0.39 feet³
Cylindrical clay boxes to be used = 4.2/0.39
=10.7 ≈ 11
Answer:
x=-7
y=2
Step-by-step explanation:
6x+9y=-24
3y=6
therefore, 9y=18,
and 6x=-42
x=-7
y=2
