Answer:
£592 for 16 boxes
Step-by-step explanation:
The classroom floor area is ...
A = LW = (8.8 m)(2.2 m) = 19.36 m²
The cupboard floor area is ...
A = (2.3 m)(2.1 m) = 4.83 m²
Then the total area to be covered is ...
19.36 m² +4.83 m² = 24.19 m²
At 1.6 m² per box, the number of boxes required is ...
(24.19 m²)/(1.6 m²/box) = 15.12 boxes
If we assume we can only purchase whole boxes, we need to purchase 16 boxes to cover the floor. The cost will be ...
(16 boxes)(£37/box) = £592 . . . . cost of laminate to replace the floor
Answer:
Step-by-step explanation:
Let X be the IQ
IQ is normally distributed with a mean of 100 and a standard deviation of 15.
a) the probability that this person has an IQ greater than 95
=
=62.93%
b) the probability that this person has an IQ less than 125

=4.75%
c) Sample size =500

No of people = 0.2486(500) =124.3
d) 
No of persons = 0.0047(500) = 2.35
Answer:
A=36
B=36
C=108
Step-by-step explanation:
A =B
2A+C=180
C is greater than A
2A+(A+72) =180
SIMPLIFY
3A +72=180
-72 ON BOTH SIDES
3A=108
DIVIDE BY 3
A=36
SO
B=36
36 TIMES 2 IS 72
180-72=108
SO
C=108
