Answer:
See Explanation
Step-by-step explanation:
For an object at temperature T and supposing that the ambient temperature is Ta then we can write the differential equation that typifies the Newton law of cooling as follows;
dT/dt=-k(T-Tₐ)
So
dT/dt = 2 degrees Celsius per minute
T = 70 degrees Celsius
Ta = 25 degrees Celsius
2 = -k(70 - 25)
-k = 2/(70 - 25)
k = - 0.044
Hence we can write;
dT/dt=-(- 0.044)(95-25)
dT/dt= 3 degrees Celsius per minute
The answer to the question is E. 2
Answer: Explained.
Step-by-step explanation: We are given to discuss why the shape cannot be described for the bar chart of qualitative data.
The distribution shape of quantitative data can be described because there is a particular order of the values but this is not the case in qualitative data. Because the data are not numeric here.
So, we cannot make bar charts and describe the shape of qualitative data to be easily readable.
Hence, the discussion is complete.
Answer:
π/2 = 90°
Step-by-step explanation:
Given that,
Radian measure = π/2
The formula used to convert radian measure to degree measure is given by :
So, the degree matches for π/2 is 90°.
