Answer:
(7x9)x10 the power of 3 is 63,000
Area = Length x Width
Area = 34 x 14
Area = 476 yd²
Answer: 476 yd²
Initial, x = 0, b = 50000
day 1, x = 1, b = 50000 (1.05)^-1
day 2, x = 2, b = 50000 (1.05) =^-2
day 2 / day 1 = 1.05^-2 / 1.05^-1 = 1.05^-1 = 0.952
Which means that the number of bacteria decreased 4.8%
Answer:
Z - score = 2.83
Step-by-step explanation:
Given the following :
Number of samples (N) = 60
Sample mean (x) = 41.9mg
Population mean (μ) = 40mg
Population standard deviation (sd) = 5.2
Using the relation :
Z = (x - μ) / (sd / √N)
Z = (41.9 - 40) / (5.2 / √60)
Z = 1.9 / (5.2 / 7.7459666)
Z = 1.9 / 0.6713171
Z = 2.8302570
Therefore, the z-score = 2.83
