The average high temperature in anchorage, alaska, in january is 21°f with a standard deviation of 10°. the average high temperature in honolulu in january is 80°f with a standard deviation of 8°. in which location would it be more unusual to have a day in january with a high of 57°f?

It would be more unusual to have a day in January with a high of 57ºF in Anchorage, Alaska.

Step-by-step explanation:

The average high temperature in Anchorage, Alaska, in January is 21°F with a standard deviation of 10°. This means that, in certain uncommon conditions, it can even reach 31ºF. So, a temperature of 57ºF would be as far as 26º from the limit of the standard deviation.

In the caso of Honolulu, the average high temperature in the same month is of 80ºF, but it can be of 72ºF in certain climatic situations. So, a temperature of 57ºF would be 15º below the limit of the standard deviation, much near than the 27º from Anchorage and, as a consequence, more likely to reach this temperature in a very strange climatic situation.

With this analysis, we can affirm that it would be more unusual to have a day in January with a high of 57ºF in Anchorage rather than Honolulu.

eve and marks ratios are equivalent

step-by-step explanation:

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
