Answer:
And we can find this probability with this difference
And we can see the figure in the plot attached.
Step-by-step explanation:
Let X the random variable that represent the redings on thermometers of a population, and for this case we know the distribution for X is given by:
Where
and
We are interested on this probability
We can use the z score formula given by:
Using this formula we got:
And we can find this probability with this difference
And we can see the figure in the plot attached.
Answer:
Point C
Step-by-step explanation:
At point C, the graph is changing from decreasing to increasing.
Solve for y.
Subtract 4x from both sides.
4x + y = 14
y = -4x + 14
