To find the minimum and maximum acceptable diameters for wheels manufactured by a machine with a 70 cm diameter tolerance set within 0.02 cm, an absolute-value equation is used to determine the range of acceptable values.
The question is: A machine manufactures wheels with a diameter of 70 cm, and it can be within 0.02 cm of this value. To find the minimum and maximum acceptable diameters, we need to set up an absolute-value equation.
Let x be the diameter of the wheel.The absolute-value equation is |x - 70| ≤ 0.02.Solving this equation, the minimum acceptable diameter is 69.98 cm, and the maximum acceptable diameter is 70.02 cm.The standard deviation is the average distance of each score in a distribution from the

Can there be more than one mean or mode in a math problem??
Final answer:
In mathematics, while a data set can have more than one mode if multiple values share the highest frequency, there is usually only one mean. The mode refers to the most common value, and the mean is the arithmetic average. Statistical tools often help calculate these measures of center.
Explanation:
Yes, there can be more than one mean or mode in a math problem. The mode is the most frequently occurring value in a data set, and a data set can have multiple modes if there are several values with the same highest frequency. When a data set has two modes, it is known as bimodal. In contrast, while there can be more than one solution to an equation (such as in quadratic equations), there is typically only one mean for a given data set. The mean is calculated by adding all the values together and dividing by the number of values. However, the mean can be influenced by skewed data or outliers more than the median or mode.
The measures of center like mean, median, and mode are critical in statistics for summarizing data. They provide different perspectives on the central tendency of the data. The mean is the arithmetic average, the median is the middle value when the data set is ordered, and the mode shows the most frequently occurring value(s). In analyzing data, statistical software or graphing calculators are often used to efficiently calculate these measures of center.
When considering the relationship between the shape of a distribution and the measures of center, typically, the mean is most affected by skewness and outliers. A skewed distribution will pull the mean toward the long tail while the median tends to resist the influence of outliers and skewed data. Mode, being the most frequent value, doesn't necessarily indicate skewness but can reveal frequency patterns within the data set.

The simplified form of the expression is x + 11.
How do we simplify the expression?To simplify the expression "x + 15 - 4", you just need to do the addition and subtraction operation:
x + 15 - 4 = x + 11
Simplifying an expression means to make it as easy to understand as possible. This can involve combining like terms, removing unnecessary parentheses, and using the distributive property.
In the expression x + 15 - 4, the like terms are x and 15. These terms can be combined to give x + 11. The parentheses around the 15 are unnecessary, so they can be removed. The simplified expression is x + 11.

Suppose you flip a penny and a dime. Use the following table to display all possible outcomes. If each single outcome is equally likely, you can use the table to help calculate probabilities. What is the probability of getting one head and one tail, on either coin?
Answer:
50%
Step-by-step explanation:
The next table display all possible outcomes.
penny | dime
head | head
head | tail
tail | head
tail | tail
If each single outcome is equally likely and there are 4 options , then all outcomes has a probability of 1/4 = 0.25 or 25%. The probability of getting one head and one tail is 50% because it's obtained by two outcomes.

prove that triangle with side lengths of x^2-1, 2x, x^2+1 is a right triangle.
pls include full proof tysm!!
A triangle with sides of lengths x^2-1, 2x, and x^2+1 is a right triangle as confirmed by the Pythagorean theorem. By squaring these lengths and simplifying the resulting equation, it's shown that the squares of the lengths of the two shorter sides sum up to the square of the length of the longest side.
Explanation:To prove that a triangle with sides of lengths x^2-1, 2x, and x^2+1 is a right triangle, we can apply the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. Therefore, if x^2-1 and 2x are two sides of the triangle and x^2+1 is the hypotenuse, then the equation becomes:
(x^2-1)^2 + (2x)^2 = (x^2+1)^2
If this equation is true, then we have a right triangle. Let's simplify the equation:
x^4 - 2x^2 + 1 + 4x^2 = x^4 + 2x^2 + 1
After simplifying, we get that 2x^2 equals 2x^2, which confirms that we indeed have a right triangle.

Sally has a credit card balance of $10,000. The credit card company charges a nominal interest rate of 17 percent a year on unpaid balances. The inflation rate is 9 percent a year. Calculate the real interest rate that Sally pays the credit card company. The real interest rate that Sally pays the credit card company is _______ percent a year.
The real interest rate that Sally pays the credit card company is 8% a year.
What is simple interest?Simple interest is a method of calculating the interest charge. Simple interest can be calculated as the product of principal amount, rate and time period.
Simple Interest = (Principal × Rate × Time) / 100
We are given that;
Balance = $10,000
Interest rate = 17 percent
Now,
The real interest rate is the interest rate that has been adjusted to remove the effects of inflation. According to 1, it can be calculated as:
Real interest rate = nominal interest rate - inflation rate
In this case, the nominal interest rate is 17% and the inflation rate is 9%. Plugging these values into the formula, we get:
Real interest rate = 17% - 9%
Real interest rate = 8%
Therefore, by the given interest the answer will be 8% a year.

If point a is located at (-12,6) on a coordinate plane, and point b is located at (4,6) what is the distance between the two points
The distance between point A at (-12, 6) and point B at (4, 6) is 16 units according to the distance formula for a coordinate plane.
Explanation:The question is asking for the distance between two points on a coordinate plane. To solve this, we use the distance formula for a coordinate plane which is D = sqrt((X2-X1)^2 + (Y2-Y1)^2), where X1, Y1 and X2, Y2 are the coordinates of the two points. In this case, both Y coordinates are the same (6), which makes the calculation simpler.
In this case, point A is at (-12, 6) and point B is at (4, 6). Subtracting the x-coordinates of A and B, (-12 - 4), we get -16, but we square this to get a positive result, which gives us 256. Since the y-coordinates are the same, the part of the equation dealing with them results in 0. So, the distance D is then the square root of 256, which is 16 units.
