A) 85 acres with 1.02 x 10⁶ plants
b) 100 acres with 1.7 x 10⁷ plants
c) 110 acres with 1.9 x 10⁶ plants
d) 205 acres with 3.4 x 10⁵ plants
a) 1.02 x 10⁶ = 1,020,000 ÷ 85 acres = 12000 per acre
b) 1.7 x 10⁷ = 17,000,000 ÷ 100 acres = 170,000 per acre
c) 1.9 x 10⁶ = 1,900,000 ÷ 110 acres = 17,272.73 per acre
d) 3.4 x 10⁵ = 340,000 ÷ 205 acres = 1658.54 per acre
Among the choices, Letter C. 110 acres with 1.9 x 10⁶ plants has the density of approximately 17000 plants per acre. Its actual density is 17,272.73 plants per acre.
Answer: 1 unit to the left, and 3 units down
Step-by-step explanation:
Answer:
4 hours
Step-by-step explanation:
The amount remaining at the end of each hour is 0.85 of the amount at the start of the hour. You want to find the exponent such that ...
... 0.85^x = 0.5 . . . . . x = the number of hours until half is left
... x·log(0.85) = log(0.5) . . . . . take the log to turn it to a linear equation
... x = log(0.5)/log(0.85) ≈ 4.265024
Rounded to the nearest hour, x = 4.
Answer:
The total frequency of deaths is 97,118.
Step-by-step explanation:
The total frequency is found by summing up the frequency of 2006, 2007, 2008 and 2009:
frequency = 6,605 + 702 + 88,011 + 1,790
frequency = 97,118.
