Answer:
Observe the attached image
Step-by-step explanation:
The inequality we have is:

This means that the region represented by this inequality includes all the values below the horizontal line
.
To graph this region, draw a dotted horizontal line that intersects the y axis at
. Then shade all the region that is below the horizontal line, as shown in the attached image.
Answer:
A
Step-by-step explanation:
180-105=75
180=75+55+x
x=50
10% chance of burning out
100-10= 90% chance of not burning out
90% = 0.9
3 lightbulbs
0.9^3 = 0.729 = 72.9%
The probability that all 3 lightbulbs stay lit by the end of the month is 72.9%
what are the measurments of the cone, but the formula to the cone is V
v = pi times radus times radius h/3
