Answer:
The answer would be D) 75,000+7,500y≥3,25000.
Step-by-step explanation:
Since there were 175,000 tons of trash in the landfill on January 1,2000, and the amount of trash in the landfill increased by 7,500 tons each year after that date, the amount of trash, in tons, in the landfill y years after January 1,2000, can be expressed as 1,75000+7,500y.
The landfill has a capacity of 325,000 tons.
Therefore, the set of years where the amount of trash in the landfill is at (equal to) or above (greater than) capacity is described by the inequality 1,75000+7,500y≥3,25000.
Answer for the first box = -31.67
Answer for the second box = 17.22
===============================================
Work Shown:
Plug in F = -25 and solve for C
F = (9/5)C+32
-25 = (9/5)C + 32
(9/5)C + 32 = -25
(9/5)C = -25-32 ... subtract 32 from both sides
(9/5)C = -57
C = (5/9)*(-57) ... multiply both sides by 5/9, its the reciprocal of 9/5
C = -31.667 approximately
C = -31.67 rounding to 2 decimal places
This shows that -25 degrees F converts to roughly -31.67 degrees C.
-----------------
Repeat the same basic steps, but now use F = 63
F = (9/5)C+32
63 = (9/5)C+32
(9/5)C+32 = 63
(9/5)C = 63-32
(9/5)C = 31
C = (5/9)(31)
C = 17.222 approximate
C = 17.22
----------------
If the temperature ranges from -25 degrees F to 63 degrees F, then this converts to the range of roughly -31.67 degrees C to 17.22 degrees C
There were 4 number of treatment conditions compared in this experiment for the given degree of freedom.
We have,
df = 3, 36
Now,
We know that,
Degree of freedom (df) = Number of treatments (t) - 1
i.e.
df = t - 1
So,
We have,
df = 3
Now,
Substituting the values,
We get,
3 = t - 1,
i.e.
t = 4
So, number of treatments conditions = 4
Hence we can say that there were 4 number of treatment conditions compared in this experiment for the given degree of freedom.
