If the variance is 5 then the standard deviation is √5.
If Z is the score then Z=(8-16)/√5=-3.58 approx.
Answer:
23°
Step-by-step explanation:
157° = D
D + C = 180°
157 + C = 180
(group like terms)
C = 180 - 157
C= 23°

Answer:
9.271 inches.
Step-by-step explanation:
Let AC be the length of original line segment and point B divides it into two segments such that AB is longer and BC is smaller segment.

We can describe the golden ratio as:






We can verify our answer as:







Hence proved.
Therefore, the length of the longer side would be 9.271 inches.
Answer:
y= 6971 -7 x OR y = -7x + 6971
Step-by-step explanation:
the 6971 is the original number you started with, you are now decreasing by 7, so you use the value of -7. The x is the number of years that pass by, so the variable x affects the number 7 because it says decreases by 7 per year. The x does not go with 6971 as that number doesn't get directly affected.
