Winston's total bill at the cash register is $1064.59
Sales tax for the items purchased is $80.59
Given,
The price for the items Winston purchased = $984
Sales tax in Winston's area = 8.19%
We have to find Winston's total bill at the cash register:
Total amount = Price of the items + sales tax amount
Sales tax amount = 8.19% of price of items
Sales tax amount = (8.19/100) × 984
Sales tax amount = $80.59
Now,
Total bill amount = Price of the items + sales tax amount
Total bill amount = 984 + 80.59
Total bill amount = 1064.59
Therefore, Winston's total bill at the cash register is $1064.59

a clothing business finds there is a linear relationship between the number of shirts, n, it can sell and the price, p, it can charge per shirt. In particular, historical data shows that 6000 shirts can be sold at a price of $81, while 10,000 shirts can be sold at a price of $45. Give a linear equation in the form p = mn + b that gives the price p they can change charge for n shirts.
Answer: p = ____
The linear equation in the form p = mn + b that gives the price p they can change charge for n- shirts is; p = (9/1000)n - 9.
What is defined as the linear equation?A linear equation is really an algebraic equation with only a constant and the first-order (linear) term of the form y=mx+b, in which m is the slope and b is indeed the y-intercept.The above is sometimes regarded to as a "linear equation of two variables," in which y and x are the variables.As per the given question;
number of shirts = n
The charge per shirt = p.
The equation describing the relation is;
p = mn + b
The price of 6000 shirts = $81.
Put the value is equation;
81 = 6,000m + b .....eq 1
The price of 10,000 shirts = $45.
45 = 10,000m + b .....eq 2
Solving eq 1 and eq 2 by elimination method.
m = 9/1000
Put the value of m in eq 2 and find b.
b = -9
Now, put the value of b and m in the equation.
p = (9/1000)n - 9
Thus, the equation in the form p = mn + b that gives the price p they can change charge for n shirts is; p = (9/1000)n - 9.

Line c is perpendicular to both line a and line b.
The statements "The product of the slopes of line a and line c is -1" and "The product of the slopes of line c and line b is -1" are both True.The reason is that a perpendicular line has a slope of -1 /m when one line has a slope of m.

The heights of three cylinders are 3cm, 9cm and 15cm. if the larger cylinder has a capacity of 725mililiters calculate calculate the capacities of the other cylinder
The capacity of 9 cm cylinder is 435 mililiters.
The capacity of 3 cm cylinder is 145 mililiters.
What is defined as the volume of cylindre?The volume of a cylinder is its density, which indicates how much material it can hold or how much of any material can be submerged in it. The volume of a cylinder is given by the formula πr²h, in which r is the radius of a circular base and h is the cylinder's height.For the given question;
The capacity of larger cylinder; 15 cm height is 725 millilitres.
Volume of 15 cm height cylinder = 725 cu. cm.
Thus,
πr²h = 725
Put h = 15 cm
πr²15 = 725
r² = 725/ 15π
r² = 145/3π
The volume of 9 cm cylinder = πr²9
Put the value of r² = 145/3π
V(h = 9 cm) = π×145×9/3π
V(h = 9 cm) = 435 cu. cm.
The volume of 3 cm cylinder = πr²3
Put the value of r² = 145/3π
V(h = 3 cm) = π×145×3/3π
V(h = 3 cm) = 145 cu. cm.

a local dog breeder wants to know if her great dane puppies weigh, on average, the same as the larger population of great dane puppies. her 16 puppies have an average weight of 6.7 pounds, with a standard deviation of 0.5 pound. the population of all great dane puppies has an average weight of 7 pounds, with a standard deviation of 0.45 pound. if she wanted to calculate the 95% confidence interval for her sample, which mean would she use in the formula?
For a confidence interval, she would use her sample mean, hence the mean of 6.7 pounds.
What is a t-distribution confidence interval?In the context of this problem, we use the t-distribution instead of the z-distribution, as we have the standard deviation for her sample.
The bounds of the confidence interval are given according to the following rule:

In which the parameters are defined as follows:
[tex]\overline{x}[/tex] is the sample mean.t is the critical value.n is the sample size.s is the standard deviation for the sample.From the first bullet point, we get that she should use her sample mean for the calculation of the confidence interval, that is, the mean of 6.7 pounds should be used.

The trigonometric expression sin(30°) + cos(60°) is equal to 1.
What is trigonometry?
Trigonometry is the study of relationships between angles and side lengths of triangles. The use of geometry in astronomical studies gave rise to the field in the Hellenistic era in the third century BC. Greek mathematicians focused on chord calculation, whereas Indian mathematicians created the earliest tables of values for trigonometric ratios (also known as trigonometric functions), such as sine.
There are two trigonometric ratios in the given expression,
sin(30°) and cos(60°).
Here, sin(30°) is equal to the value 1/2
i.e. sin(30°) = 1/2
And, cos(60°) is equal to the value 1/2
i.e. cos(60°) = 1/2
Adding these equations, we get
sin(30°) + cos(60°) = 1/2 + 1/2 = 2/2 = 1
therefore, on solving the given trigonometric expression we get answer value 1.

With a 95% confidence interval, the average is between 13.4667 and 26.5333.
Confidence interval is the measure of the degree of uncertainty or certainty in a sampling method. It is equal to the sample mean, plus or minus the margin of error (z value multiplied by standard deviation divide by the square root of the sample size).
CI = x ± z(σ/√n)
where CI = confidence interval
x = mean
σ = standard deviation
n = sample mean
z = z value at the confidence interval
The corresponding z value at 95% confidence interval is 1.96.
Substitute the given into the formula and solve for CI.
CI = x ± z(σ/√n)
CI = 20 ± (1.96)(10/√9)

What are mathematical operations?An operation in mathematics is a function that converts 0–n parameters or operands into a definite output value. The complexity of the operation depends on how many operands there are.
The operations that are most frequently studied are binary operations (i.e., operations of arity 2), which include addition and multiplication, and unary operations (i.e., operations of arity 1), which include additive inverse and multiplicative inverse. A zero-arity operation, also known as the nullary operation, is a constant. An illustration of a ternary operation, also known as an operation of arity 3, is the mixed product.
Usually, it is considered that the arity is constrained. Even so, infinitary operations are occasionally considered, in which case the "normal" finite dimensionality operations are referred to as finiteary operations.
A partial operation is described as being similar to an operation but using a partial function in place of a function.
