The gradient of this straight line through the points is 0.16.
The gradient of this lines simply means that it would require one (1) unit to use £0.16 worth of electricity.
How to calculate the gradient of a line?Mathematically, the gradient of a straight line can be calculated by using this formula;
Gradient, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)
Gradient, m = (y₂ - y₁)/(x₂ - x₁)
From the information provided through this graph, we have the following data points:
Points on x-axis = (30, 100).
Points on y-axis = (4, 15).
Substituting the given points into the formula, we have the following;
Gradient, m = (15 - 4)/(100 - 30)
Gradient, m = 11/70
Gradient, m = 0.16
This ultimately implies that, £0.16 worth of electricity would require one (1) units to be used by David.

Apply the Multiplication Property of Equality to write an equation equivalent to 7n = 28
due today lol
The equivalent equation is when n is equal to 4.
What is Multiplication Property of Equality?According to the multiplication property of equality, when we multiply both sides of an equation with the same number, the two sides remain equal.When we multiply either sides of an equation by the same number, the two sides remain equal, according to the multiplication property of equality. That is, if a, b, and c are all real numbers and a = b, thenaxc = bxc.
The four equality properties of addition, subtraction, multiplication, and division can be used to solve an equation. We simply add, subtract, multiply, or divide both sides of an equation to find the value of an unknown variable.Here given equation,
7n = 28
Multiply both sides of equation by 1/7
7n x 1/7 = 28 x 1/7
7n / 7 = 28 / 7
n = 28 / 7
n = 4
So the equation equivalent to 7n = 28 is n = 4.

if someone else collected a different sample from your population and measured the same variable, would they calculate the same sample statistic?
It is possible that someone else collecting a different sample from the same population and measuring the same variable would calculate the same sample statistic, but it is not guaranteed.
What is meant by Sample Statistic?Statistical measures that are derived from samples of data rather than the complete population are called sample statistics. A population parameter, such the mean or standard deviation, is estimated using this method. Depending on the type of data and the research issue being examined, sample statistics can be estimated using a variety of formulae and techniques. For instance, to get the sample mean, multiply the sum of all the observations in the sample by the total number of observations. The sample standard deviation is calculated by taking the square root of the sum of the squared differences between each observation and the sample mean. In research studies and surveys, sample statistics are frequently utilized to draw conclusions about the population.

A jar of coins contains six times as many quarters as dimes if the totalamount of money is 28.80 how many quarters and dimes are in the jar
There are total amount of 108 quarters and 18 dimes in a jar.
What is total?Total refers to a whole or full amount, and the verb "to total" means to combine two numbers or to destroy anything. In mathematics, you add integers to get the total; the outcome is the total. The result of adding 8 and 8 is 16.
There are six times more quarters than dimes in a jar of coins.
If x represents the dimes, then the number of quarters will be 6*x if there are 28.80 in total.
A dime is worth 10 cents. In terms of money, we have 10 times as many dime.
A quarter is equal to 25 cents. We have 6 times as many quarters, which is 150 times (6 x 25).
10x +150x = 28.80
160x = 28.80
x = 0.18 that is for coins it will be 10x
10*0.18
18 dimes
similarly
6 times dimes is equal to quarters that is 6*18
108 quarters are there.

What is division?One of the four fundamental arithmetic operations, or how numbers are combined to create new numbers, is division.
The other operations are multiplication, addition, and subtraction.
On a fundamental level, counting the instances in which one number is included within another is one interpretation of the division of two natural numbers.
It's not necessary for this number to be an integer.
For instance, if 20 apples are distributed equally among 4 persons, each person will get 5 of them.
So, we have 451/51.
Now calculate as follows:
451/51
Quotient = 008

What is Equation?A mathematical statement that has a "equal to" symbol between two expressions with equal values is called an equation. as in 3x + 5 Equals 15, for instance.
Equations come in a variety of forms, including linear, quadratic, cubic, etc.
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. We have LHS = RHS (left hand side = right hand side) in every mathematical equation.
To determine the value of an unknown variable that represents an unknown quantity, equations can be solved. The statement is not an equation if there is no "equal to" symbol in it.
According to our question-
M being on LN, then
LN equals LM plus MN, therefore
4x = 3 + x ( remove x from both sides ) ( subtract x from both sides )
3x Equals 3 ( divide both sides by 3 ) ( divide both sides by 3 )
x = 1
Then
LN = 3 + x = 3 + 1 = 4
Hence, LN = 4 units, the numerical length of \overline{LN}.

Find the total cost: Alexandra bought a television set for $1105 in New York, where the sales tax rate was
8.75% of the purchase price.
The total cost of the Television is $ 1201.68.
What is Sales tax:The governments collect a consumption tax known as a sales tax on purchasing goods and services. It is always expressed as a percentage of the Purchase cost of goods and services. Here
Total cost = Purchase price + sales tax.Here we have
Alexandra bought a television set for $ 1105 in Newyork
The rate of sales tax = 8.75%
Therefore,
The total cost of Television = Cost of Television + sales tax
As we know sales tax = 8.75%
=> tax on Television = 8.75% of 1105
= [tex]\frac{8.75}{100} \times 1105[/tex]
= 0.0875 × 1105
= 96.68
The total cost of Television = 1105 + 96.68
