Answer:
6.68 %.
Step-by-step explanation:
The standardised z-score = ( 10.95 - 10.5) / 0.3
= 1.5.
Looking up the Normal Distribution tables ( area to the left) 1.5 corresponds to 0.93319 so for a weight above 10.95 the proportion is
1 - 0.93319 = 0.06681
= 6.68%.
Answer:
Rephrase that so that x=the number.
3+2x=x
(-2x) => 3=-x
(*-1) => -3=x
Therefore the number is -3!

(B) - Yes, because the amount owed changes by 2.25 every time the miles change by 1.
Starting at 1 mile the price is 2.5 dollars.
Mile 2 is 4.75 dollars. What is the difference between 4.75 and 2.5? 2.25
Mile 3 is 7 dollars. What is the difference between 7 and 4.75? 2.25
Mile 4 is 9.25 dollars. What is the difference between 9.25 and 7? 2.25
Mule 5 is 11.5 dollars. What is the difference between 11.5 and 9.25? 2.25
The change is always 2.25 dollars.
The change is 2.25 dollars per mile.
One way to solve for this is (11.5 - 2.5)/(5-1)=2.25
This is (y2-y1)/(x2-x1). By picking 2 points, (x1,y1) and (x2,y2) you can solve for the slope (rate of change) between them.
