Step-by-step explanation:
Given inequality is .
To graph that inequality, first we need to graph the line . Then shade it for the inequality symbol <.
Graphing line can be done using two points.
plug x=0 into , we get:
Hence first point is (0,2)
Similarly plug any random number for x say x=4, we get:
Hence first point is (4,5).
Now we just need to graph both points and join them by a dotted line. because we have < not <=.
Next part is to test for shading.
Which can be done using any test point which is not on the given line. Say (0,0)
plug x=0,y=0 into .
0<2
which is true, hence shading will be in direction of test point (0,0).
Hence final answer will be the choice which looks like the graph attached below;
Answer: 0.00102%
Step-by-step explanation:
Given : Human body temperatures are normally distributed with a mean of and a standard deviation of
A hospital uses as the lowest temperature considered to be a fever.
Let x be the random variable that represents the human body temperatures.
For x= 100.6,
Using normal distribution table for z-values for right-tailed area ,
P(x>100.6)=
Hence, the required probability = 0.00102%
