Step-by-step explanation:
Given :
The average summer temperature in Anchorage is 69°F.
The daily temperature is normally distributed with a standard deviation of 7°F .
To Find:What percentage of the time would the temperature be between 55°F and 76°F?
Solution:
Mean = 
Standard deviation = 
Formula : 
Now At x = 55


At x = 76


Now to find P(55<z<76)
P(2<z<-1)=P(z<2)-P(z>-1)
Using z table :
P(2<z<-1)=P(z<2)-P(z>-1)=0.9772-0.1587=0.8185
Now percentage of the time would the temperature be between 55°F and 76°F = 
Hence If the daily temperature is normally distributed with a standard deviation of 7°F, 81.85% of the time would the temperature be between 55°F and 76°F.

I think y= -1/3x
sorry if wrong
Step-by-step explanation:
The 3 angles of a triangle have to add up to 180 degrees. Since we are given 2 of the angles, all we have to do is add them up and then subtract from 180 to get the 3rd.
112 + 41 = 153
180 - 153 = 27
Angle 2 = 27 degrees.
