What is percentage?A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.
Given, You (or your parents) purchase a new car for $19,725.00 plus 4.75% sales tax. The down payment is $2,175.00 and you (or your parents) have an average credit rating.
The cost of car = 19,725*(1.0475) = 20,661.9375
Down payment = 2,175
So balance amount, P= 20661.9375-2175 = 18,486.9375
So interest for the average rating of a new car = 6.30%
So the interest accrued in first month = 18,486.9375*0.063/12 = $ 97.056
therefore, interest accrued after the first month is $97.056.

On multiplying 55 × 35, the answer is 1925.
The simplest way to start teaching multiplication is to establish the relationship between the concept and addition, which your pupils should already be familiar with. Make sure your students understand the first principle of multiplication—that it is just repeated addition—before continuing on.
Your youngster can learn that multiplication is actually just a means to repeatedly add multiple groups of the same number by using objects like blocks and small toys. For instance, ask your youngster to arrange the blocks into six groups of three by writing the issue 6 x 3 on a sheet of paper.

the lifetime of a certain brand of car battery has an exponential distribution with a mean of 60 months. find the probability that a randomly selected battery of this kind lasts longer than 70 months (round off to second decimal place).
Answers
The probability that a randomly selected battery of this kind lasts longer than 70 months is approximately 0.104(rounded off to the second decimal place).
The cumulative distribution function of an exponential distribution with a mean of 60 months is given by:
F(x) = 1 - e^(-x/60)
The probability that a randomly selected battery lasts longer than 70 months is given by:
P(X > 70) = 1 - F(70) = 1 - (1 - e^(-70/60)) = e^(-70/60) = 0.104
So, the probability that a randomly selected battery of this kind lasts longer than 70 months is approximately 0.104 (rounded off to the second decimal place).

Let f(x) = 4x + 3 and g(x)=x²-x+1. Perform the function operation and then find the domain.
g(x)-f(x)
g(x)-f(x) = (Simplify your answer.)
Answers
The domain of g(x) - f(x) is all real numbers, or (-∞, ∞).
What is the domain?
The domain of a function is the set of all possible input values (x-values) for which the function is defined and produces a valid output (y-value). In other words, it is the set of values for which the function is valid and can be used without producing any errors or undefined results.
To perform the function operation g(x) - f(x), we need to subtract the function f(x) from the function g(x).
g(x) = x² - x + 1
f(x) = 4x + 3
g(x) - f(x) = x² - x + 1 - (4x + 3)
g(x) - f(x) = x² - 5x - 2
The domain of a function is the set of all possible input values (x-values) for which the function is defined and produces a valid output (y-value).
For the function g(x) - f(x) = x² - 5x - 2, there are no restrictions on the input values, meaning that any value of x can be plugged into the function to produce a valid output.
Therefore, the domain of g(x) - f(x) is all real numbers, or (-∞, ∞).

There are six crucial parallelogram characteristics to be aware of:
Congruent sides are those when AB = DC.Congruent opposite angels are D = B.Consecutive angles are supplementary.All angles are correct if just one of them is.A parallelogram's diagonals cut each other in half.A parallelogram's diagonals divide it into two congruent.A rhombus is what we have when all of the sides of a parallelogram are congruent. Rhombi can use the characteristics of parallelograms.
We have a quadrilateral that is referred to as a trapezoid if just one pair of its sides are parallel. While the nonparallel sides are referred to as legs, the parallel sides are known as bases. We have what is referred to as an isosceles trapezoid if the legs are congruent.

Answers
The least amount of time spent per week on meetings for the sample of 25 CEOs is 12 hours.
The least amount of time spent per week on meetings for the sample of 25 CEOs can be found by looking at the lowest value in the data set. The data set provided above lists the time spent per week on meetings for a sample of 25 CEOs, and the least amount of time spent is 12 hours per week.
This is the smallest value in the data set, and it represents the minimum amount of time spent on meetings among the CEOs in the sample.
Note that this data is a sample of 25 CEOs and not the entire population of CEOs, so it is not representative of all CEOs. Additionally, the time spent per week on meetings is a quantitative variable, and it is continuous. Therefore, it is recommended to use measures of central tendency (mean or median) and measures of dispersion (standard deviation, range) to make inferences about the population.

In mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has exactly one output and the output can be linked to its input.
The graph of the function f(x) is graphed and the graph is given.
The average rate of change is a measure of how much the function changed per unit, on average, over that interval.
For a function f(x) at interval [a,b], the average rate of change is given as -
[f(b) - f(a)]/(b - a)
The interval values is given as - [-1,3]
The value for f(a) as seen in the graph is - 4.
The value for f(b) as seen in the graph is - -4.
Substitute the values in the equation -
Average rate of change = [f(b) - f(a)]/(b - a)
A = (-4 - 4)/[3 - (-1)]

given, One angle of a triangle measures 35°. The other two angles are in a ratio of 10:19.

A representative sample is nothing but a sample / a subset of a population that accurately reflect the characteristics of the larger group.
For example, consider a class of 50 students with 25 girls and 25 boys.
We can generate a representative sample that might include ten students: five girls and five boys.
As we know the samples contain smaller, manageable versions of the larger group, they are useful in statistical analysis when population size is large.

784 + 784 = c^2
1568 = c^2
Square root both sides.
c = about 39.6 inches diagonal length
for how many values of the constant k will the polynomial x2 kx 36 have two distinct integer roots?
Answers
There are 2 values of k, 12 and -12, for which the polynomial x^2 + kx - 36 has two distinct integer roots.
The polynomial x^2 + kx - 36 has two distinct integer roots if and only if its discriminant is a perfect square.
The value of the discriminant is given by:
b^2 - 4ac = k^2 + 4 * 36 = k^2 + 144
So, for the polynomial x^2 + kx - 36 to have two distinct integer roots, k^2 + 144 must be a perfect square.
We know that the difference of two consecutive perfect squares is equal to an odd number, so we can start testing values of k by incrementing k by 1 and checking if k^2 + 144 is a perfect square.
Starting with k = 0, we have k^2 + 144 = 144, which is not a perfect square. For k = 1, k^2 + 144 = 145, which is also not a perfect square.
For k = 2, k^2 + 144 = 148, which is still not a perfect square.
We keep incrementing k and checking until we find a value of k such that k^2 + 144 is a perfect square.
When k = 12, we have k^2 + 144 = 168, which is a perfect square (12^2).
Therefore, the polynomial x^2 + 12x - 36 has two distinct integer roots.
We can repeat this process for negative values of k to see if the polynomial has two distinct integer roots for those values.
We find that for k = -12, the polynomial x^2 - 12x - 36 also has two distinct integer roots.
