Answer:
He fails to sell that day 10 cottons.
Step-by-step explanation:
We are given that a cotton candy merchant earns 40 cents for each cotton sold, but if he cannot sell it he loses 50 cents.
One day when he made 120 cottons, he made a profit of 39 soles.
Let the number of cottons merchant is able to sold be 'x' and the number of cottons merchant is not able to sold be 'y'.
So, according to the question;
- The first condition states that he made 120 cottons on one day, that is;
x + y = 120
x = 120 - y ---------------------- [Equation 1]
- The second condition states that merchant earns 40 cents for each cotton sold, but if he cannot sell it he loses 50 cents and due to which he made a profit of 30 soles, that is;
This means that the merchant is not able to sell 10 cottons.
Answer:
The function p = 75h represents this situation.
Step-by-step explanation:
We know the equation of linear equation in the slope-intercept form is
where
m = rate of change = slope
b = y-intercept
- Let 'h' be the number of hours
- Let 'p' be the pay
Given that Lian is paid SR 75 per hour.
so the rate of change of slope = m = 75
As there is no initial condition, so b = 0
as
y = mx+b
Now, mapping the information data into the slope-intercept form
- p = y
- m = 75
- h = x
- b = 0
Thus, the equation becomes
p = 75h
Therefore, the function p = 75h represents this situation.
VERIFICATION:
Given the equation
p = 75h
for h = 1
p = 75(1)
p = 75
Thus, Liam is paid SR 75 per hour.
Solution :
Given :
X = homicide rate (homicides per 100,00 population)
n = 12 = metropolitan areas
Area X (homicides per 100,000 population)
Mesa, AZ 4.1
Seattle, WA 3.8
Portland, OR (tie) 3.4
New York, NY(tie) 3.4
Virginia beach, VA 3.3
San Jose, CA 3.1
EI, Paso, TX 2.6
Austin, TX 2.6
San Diago, CA 2.4
Suffolk County 2.2
Montgomery, MD 2.0
Fairfax, VA 1.7
Therefore, the mean of X =
= 2.9
Therefore, the mean of homicide rater in the 12 metropolitan areas is 2.9 homicide per 100,000 population.
