Answer:
8246=x+180
x=8066 miles
Step-by-step explanation:
Let the initial readings be x
The final reading is the sum of initial reading and distance covered hence
Final=Initial + distance covered
Substituting 8246 miles for the final miles and 180 miles for the distance traveled to Grandma's house
8246=x+180
Solving for x
x=8246-180=8066 miles
Answer: Y= 86 X=94
What I did is, the angle minus 86 to give me 94
Formula

Z=standard score
x=observed value
u=mean of the sample
standard deviation of the sample
A is 6, a = 6
b = -1 - 7a
b = -1 - 7(6)
b = -1 - 42
b = -43
