The area under the density curve that lies to the right of 11 is 0.322. What percentage of all possible observations of the variable are at most 11?

67.8%

Step-by-step explanation:

The variables that are at most 11 will lie on the left of 11.

The percentage of the possible observations to the left will be:

= 1 - percentage to the right

= 1 - 0.322

= 0.678

= 67.8%

image result for what is another name for consecutive interior angles? ​

when two lines are crossed by another line (called the transversal): the pairs of angles on one side of the transversal but inside the two lines are called consecutive interior angles. in this example, these are consecutive interior angles: d and f.

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
