Answer:
The reaction ca occur at 10 degree Celsius or -14 degree Celsius.
Step-by-step explanation:
We are given the following in the question:
The completion of a chemical reaction is expressed by the equation
where y is the number of seconds needed to complete the reaction and x is the temperature in degrees Celsius at which the reaction occurs.
We have to find the temperature at which the reaction occurs, if the completion time of reaction is 160 seconds.
Putting y = 160
Thus, the reaction ca occur at 10 degree Celsius or -14 degree Celsius.
Answer:
Q1: S(r)= 200/r
Q2: a: dv= 20pie
B: relative error: dv/v =1/16
%error= 6.25%
Step-by-step explanation:
Attached is the complete solution.
Step-by-step explanation:
With a fair die, the probability of rolling a 6 is 1/6 or 0.167.
For the baked die, the low end of the confidence interval is 0.215 − 0.057 = 0.158.
Since 0.167 is within the range of the confidence interval, there is not convincing statistical evidence that a baked die will have a higher probability of rolling a 6 than a fair die.
Let P be the cost of pucks, S the cost of sticks.
1.5p+3s=23
2.5p+s=20
subtract eqn 2 from 1,we get
5p+3s-5p-s=23-20
2s=3
s=3/2=1.50
Then from eqn 2,
5p+3/2=20
5p=40/2-3/2
p=37/10=3.70
Therefore,pucks cost $3.70 and sticks cost $1.50
