In a lab, a substance was cooked by 42 c over a period of 7 hours at a constant rate. what was the change in temperature each hour

Given that we have the change in temperature over 7 hours and we are looking for the change over 1 hour, we can divide the total change in temperature by 7. Thus, the change in temperature would be .

Additionally, this can be solved by equations:

By using two different methods, we can determine that the change each hour was equal to 42/7 C° per hour.

where is the rest of the

step-by-step explanation:

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
