We base ourselves in the one piece of crucial evidence: She has 2 quarters.
-from the rest of the problem, we know that she has 2 more NICKEL'S than QUARTERS,
(2 Quarters + 2 = 4 nickels)
she has 3 fewer nickels than dimes,
DIME - 3 = Nickels
D - 3 = 4
D = 7
7 dimes
(70 cents)
4 nickels
(20 cents)
2 quarters
(25 cents)
115 cents
or $1.15
You divide 18 with 3 and is going to equal 6 so that should be your constant proportionality
Answer:

Step-by-step explanation:
Hi there!
Linear equations are typically organized in slope-intercept form:
where m is the slope (also called the gradient) and b is the y-intercept (the value of y when x is 0)
<u>1) Plug the gradient into the equation (b)</u>

We're given that the gradient of the line is 4. Plug this into
as m:

<u>2) Determine the y-intercept (b)</u>

Plug in the given point (1,10) as (x,y) and solve for b

Subtract 4 from both sides to isolate b

Therefore, the y-intercept of the line is 6. Plug this back into
as b:

I hope this helps!

Answer:
Simple random sampling survey method
Step-by-step explanation:
A simple random sampling is an unbiased survey technique Hence it will represent all the parts of the city's population.
In statistics, a simple random sample is a subset of individuals (a sample) chosen from a larger set (a population). Each individual is chosen randomly and entirely by chance, such that each individual has the same probability of being chosen at any stage during the sampling process
