Answer:
is this a question? also, 6/4 is not irrational, it is rational, and an irrational number is a number that cannot be expressed as a ratio of two integers, aka a simple fraction
Answer:

Step-by-step explanation:
We are given the following in the question:
A storage shed is to be built in the shape of a (closed) box with a square base.
Volume = 150 cubic feet
Let s be the edge of square base and h be the height.
Volume of cuboid =

where l is the length, b is the base and h is the height.
Volume of box =

Area of base =

Cost of concrete for the base = $4
Cost of base($) = 
Area of roof =

Cost of material for the roof = $2
Cost of roof ($) = 
Area of 4 walls =

Cost of material for the side = $2.50
Cost of material of side($) =

Total cost
= Cost of base + Cost of 4 sides + Cost of roof

is the required cost function.
Answer:
Probabilty of not poor= 0.75
Step-by-step explanation:
total of 11332 bonds.
7311 are good risk.
1182 are medium risk.
Poor risk
= total risk-(good risk+ medium risk)
= 11332-(7311+1182)
= 11332-8493
= 2839.
Poor risk = 2839
Probabilty that the ball choosen at random is not poor= 1 - probability that the ball is poor
Probability of poor = 2839/11332
Probabilty of poor= 0.2505
Probabilty that the ball choosen at random is not poor= 1- 0.2505
= 0.7495
To two decimal place= 0.75
