Two candles=8 hours=8*60=480 minutes
4 inch is 4/12 of a candle, 4/12 of 4 hours=16/12=4/3 hours=80 minutes
so the total minutes are 480+80=560
We can assume that the y-intercept for this equation is 125, because that would be how much Anna already has saved before she begins saving money from her allowance. Then, we know that Anna adds $2 to her savings each day from the problem, so we know that the slope will be positive 2 then.
Equation:
y = 2x + 125

Answer:
205.3 pounds
Step-by-step explanation:
Answer:
Point (4,7) completely satisfies the equation and is a solution to the equation.
Step-by-step explanation:
Given:
Equation: 
To check if the point (4,7) is a solution to the given equation.
Solution:
The solution of an equation is given as
which completely satisfies the equation.
To check if the point (4,7) is a solution to the given equation, we will plugin
and
in the given equation and see if it satisfies it or not.
Plugging in point (4,7) in the equation:

Simplifying.


The above equation is always true, and hence point (4,7) completely satisfies the equation and is a solution to the equation.
Mean = 3550
SD = 870
Find P(1810 <x<4420)
z = x -mean / sd
= (1810 - 3550 / 870) < z< (4420 - 3550 / 870)
= -2 <z< 1
Using the -z table -2 = 0.0228 and 1 = 0.8413
Subtract: 0.8413 - 0.0228 = 0.8185 x 100 = 81.85%
Rounding everything may change answer slightly so
The closest one is B 81.5%
