Given:
Actual: 9.0 lbs with standard deviation of 0.35 lbs
sample: 8.2 lbs
standard deviation means that the fish caught should be within the range of 8.65 and 9.35
9.00 + 0.35 = 9.35 lbs
9.00 - 0.35 = 8.65 lbs
The sample that had an average weight of 8.2 lbs is not a representative of the population because its weight goes beyond the standard deviation.
Answer:
y=2x+2
Step-by-step explanation: y=mx+b
To find M:
10-(-2) divided by
4-(-2) equals
12/6=3
To find B:substitute
10=2(4) +b
10=8+b
-8 -8
2=b
Answer:
1344
Step-by-step explanation:
100cm = 1 m
Convert the dimensions of the floor to cm = Area of a rectangle = length x breadth = 320 x 280 = 89,600m²
Area of a square = length² = 10cm² = 100cm²
Number of tiles that would be needed = area of floor / area of square
89,600cm² / 100cm² = 896
Cost of one tile = rs 150 / 100 = 1.5
Cost of 896 tiles = 1.5 x 896 = 1344
