He started out with 47 balls after winning 2 blue balls and losing 3 red balls.
What is equation?The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign. Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation. Equal treatment should be given to each party.
Here,
Let the number of blue balls be x and the number of red balls be y,
after 5 days ,
x + 10 = y - 15
after 9 days ,
x + 18 = 2 * ( y - 27 )
subtracting both,
8 = y - 39
y = 47
The number of red balls in beginning is 47.
He had 47 balls in the beginning as he win 2 blue ball and lose 3 red balls.

Identify each output value for the given input value if the rule of the table is to add -6.
The output values from the rule are -12, 2, 0, -6 and -10
How to determine the output valuesFrom the question, we have the following parameters that can be used in our computation:
Rule = add -6
This means that
Output = Input - 6
Using the values in the question, we have
Output = -6 - 6 = -12
Output = 8 - 6 = 2
Output = 6 - 6 = 0
Output = 0 - 6 = -6
Output = -4 - 6 = -10

Write the equation of the line passing through the points (-3,3) and (3,1).
The equation of the line is?
Answer:
y = -1/3x + 2
Step-by-step explanation:
Slope-intercept form of a linear equation is written as:
y = mx + b, where x and y are coordinates from one of the points on the line, m is the slope, and b is the y-intercept.
1. You'll first want to find the slope, m. Slope can be calculated from two points by using the equation (y1 - y2)/(x1 - x2). If you plug your two points into this equation for x and y (making sure that y1 and x1 are from the same point and y2 and x2 are from the other), you'll get,
(3 - 1)/(-3 - 3) = 2/-6 = -1/3
m = - 1/3
2. You can then plug your slope, m, into the slope-intercept form of the equation. Using one of your points (doesn't matter which, but I'll use (3,1)), you can solve for b, your y-intercept.
1 = -1/3(3) + b
1 = -1 + b
b = 2
3. Plug the variables into the equation.
For your final equation, plug the slope, m, and y-intercept, b, that you just found.
y = -1/3x + 2

The area of a triangle is 36 cm2. The height of the triangle is 6 cm less than the base. What is the height of the triangle?.
Answer:
[tex]\huge{\boxed{\text{The height of the triangle is 6cm.}}}[/tex]
Step-by-step explanation:
This question requires us to use a system of equations.
The area of a triangle is (1/2) * (base) * (height).
Thus, if b = base, and h = height
[tex]\frac{1}{2} bh=36[/tex]
Additionally, from the problem, we know:
[tex]b=h+6[/tex]
Then, via substitution, we can get
[tex]\frac{1}{2} *(h+6)*h=36[/tex]
Then, simplify:
[tex]\frac{1}{2} h^2+3h=36[/tex]
[tex]\frac{1}{2} h^2+3h-36=0[/tex]
[tex](\frac{1}{2} h-3)(h+12)=0[/tex]
Thus, the height must equal either 6 or -12, and because height cannot intrinsically be negative, the height must be 6.

b. If Ron's average daily balance is correct, what should the finance charge be?
The credit card company calculated a finance charge of $7.66 on Ron's bill if the annual percentage rate is 18%.
What is finance charges?A finance charge is any fee that represents the cost of credit or borrowing. It is the interest and fees charged for certain types of credit. It includes not only interest but also other charges like financial transaction fees.A financing charge is, to put it simply, any fee incurred when using credit. A finance charge is the total of all fees that are imposed incidentally to the extension of credit by the creditor and are paid directly or indirectly by the person to whom credit is extended, according to the Truth in Lending Act's legal definition.Your monthly statement from your credit card company will include a list of all finance charges in addition to your purchases and payments. Your card issuer will determine how your finance fee appears on your statement.The finance charge is the product of the average daily balance and the monthly percentage rate.
The annual percentage rate (APR) is 18% or 0.18.
$510.50× 0.18 / 12 =$7.66

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.
