we are going to create a table in excel and we will assign different values of topping to know when the price is equal in both pizzerias
see the attached figure
the answer is
5 toppings from palanzio’s pizzeria
6 toppings from guido’s pizza
cost palanzio’s pizzeria----> 6.80+0.90*5-----> $11.30
cost <span>guido’s pizza------> 7.40+0.65*6----------> $11.30</span>
Answer:
Step-by-step explanation:
a)
Confidence interval in less than symbol expressed as
Where is sample mean and
is margin of error.
b)
The given t interval is
That is and
Solve these two equation by adding together.
Solve this value of \bar{x} in equation and solve for
Best point estimate of
Best point estimate of margin of error = 0.193
c)
Since sample size = 100 which is sufficiently large (Greater than 30) , it is no need to confirm that
sample data appear to be form a population with normal distribution.
This question is solved using a system of equations, and doing this, we get that: There are 9 quarters, 4 nickels and 12 dimes.
I am going to say that:
x is the number of nickels.
y is the number of dimes.
z is the number of quarters.
In all, they are worth $3.65.
A nickel is worth $0.05, a dime is worth $0.1 and a quarter is worth $0.25, so:
Dimes: 3 times greater than nickels:
This means that:
Quarters: One greater than double the number of nickels:
This means that:
Value of x:
We have y and z as function of x, so we can replace into the equation and find the value of x, so:
y and z:
There are 9 quarters, 4 nickels and 12 dimes.
