Answer:

$84.5

Step-by-step explanation:

First you want to find what 35% of 130 is:

$130.00 x 0.35 = 45.5

(In order to do this you have to turn the percentage into a decimal by dividing by 100: 35% ÷ 100 = 0.35)

Now you need to subtract what 35% of 130 is from 130:

130 - 45.5 = 84.5

Answer:84.50

Step-by-step explanation:

original price/discount

$130x.35=45.5

original price -discount

130-45.5

84.50

The inside diameter would be the outside diameter minus 2 of the wall thicknesses.

4 9/32 - (2 x 7/32)

Simplify:

4 9/32 - 14/32

Because 14/32 is larger than 9/32 change one of the hole numbers to a fraction: 1 = 32/32

rewrite 4 9/32 as 3 41/32

Now subtract:

3 41/32 - 14/32 = 3 27/32 inside diameter.

Hexadecimal and binary are two numbering systems that are commonly used in computing. Binary is a base-2 numbering system, which means it uses only two digits, 0 and 1, to represent all numbers. Hexadecimal, on the other hand, is a base-16 numbering system, which means it uses 16 digits, from 0 to 9 and A to F, to represent numbers.

One hexadecimal digit can represent 16 different values, while one binary digit can represent only two values (0 or 1). This means that one hexadecimal digit can represent 16 times as many values as one binary digit.

To understand this better, let's consider an example. The binary number 1111 is equivalent to the hexadecimal number F. In binary, 1111 can represent only one value, which is 15 in decimal. However, in hexadecimal, the digit F can represent 16 different values, from 0 to 15 in decimal.

Therefore, using hexadecimal notation can be more efficient and compact than using binary notation, especially when dealing with large numbers. In addition, hexadecimal is often used in computing to represent memory addresses, color codes, and other values that need to be represented in a compact and easily readable format.

when k = 4, the function x + k/x will have a relative maximum at x = -2.

To find the value of k that will make x+k/x have a relative maximum at x=-2, we can use the first derivative test.

First, we find the derivative of x+k/x with respect to x:

f'(x) = 1 - k/x^2

Next, we set x = -2 and solve for k to make f'(-2) = 0:

f'(-2) = 1 - k/(-2)^2 = 1 - k/4

1 - k/4 = 0

k = 4

what is derivative?

A derivative is a mathematical concept that represents the rate at which a function changes over time or space. It is the slope of a tangent line to a curve at a particular point.

In other words, the derivative of a function f(x) at a point x=a is defined as the limit of the difference quotient as h approaches zero:

f'(a) = lim[h→0] [f(a+h) - f(a)]/h

The derivative gives us information about how quickly the function is changing at a specific point.

Answer:

Step-by-step explanation:

if it's talking about between the numbers 75 to 97, then it's 22.

Answer:

We conclude that:

\(25a^2-0.01b^{10}=\left(5a+0.1b^5\right)\left(5a-0.1b^5\right)\)

Step-by-step explanation:

Given the expression

\(25a^2-0.01b^{10}\)

Rewrite \(25a^2-0.01b^{10}\) as \(\left(5a\right)^2-\left(\sqrt{0.01}b^5\right)^2\)

so

\(25a^2-0.01b^{10}=\left(5a\right)^2-\left(\sqrt{0.01}b^5\right)^2\)

Apply difference of two squares formulas:

\(x^2-y^2=\left(x+y\right)\left(x-y\right)\)

so

\(\left(5a\right)^2-\left(\sqrt{0.01}b^5\right)^2=\left(5a+\sqrt{0.01}b^5\right)\left(5a-\sqrt{0.01}b^5\right)\)

                               \(=\left(5a+0.1b^5\right)\left(5a-0.1b^5\right)\)    ∵ \(\sqrt{0.01}=0.1\),

Therefore, we conclude that:

The mean squared error equals to c.) 6.

The mean squared error is a measure of the accuracy of a forecast model, indicating the average squared difference between the forecasted values and the actual values in a time series. In this case, a three-period moving average forecast is used.

To compute the mean squared error, we need to calculate the squared difference between each forecasted value and the corresponding actual value, and then take the average of these squared differences.

Using the given time series values and the three-period moving average forecast, we can calculate the squared differences as follows:

(23 - 17)² = 36

(17 - 17)² = 0

(17 - 26)² = 81

(26 - 11)² = 225

(11 - 23)² = 144

(23 - 17)² = 36

(17 - 17)² = 0

Taking the average of these squared differences, we get:

(36 + 0 + 81 + 225 + 144 + 36 + 0) / 7 = 522 / 7 ≈ 74.57

Therefore, the mean squared error is approximately 74.57.

In a circle centered at point o, the ratio of the area of sector AOB to the area of the circle. Calculating the measure of central angle

From the question, we are to calculate the measure of the central angle corresponding to arc AB

From the given information, The ratio of the area of sector AOB to the area of the circle is 3/5

The area of a sector is given by the formula,

Area of sector = (θ/360°) *πr² , Where 'θ' is the central angle of the circle and 'r' is the radius of the circle

3/5 = θ/2π

5θ = 6π

θ = (6/5) π

The approximate percentage of daily phone calls numbering between 26 and 56 is :

99.7%

In a mid-size company with a bell-shaped distribution of phone calls answered by 12 receptionists, the mean is 41 and the standard deviation is 5. Using the empirical rule, we can approximate the percentage of daily phone calls numbering between 26 and 56.

Determine the range in terms of standard deviations from the mean.
- Lower bound: (26 - 41) / 5 = -3 standard deviations
- Upper bound: (56 - 41) / 5 = 3 standard deviations

Apply the empirical rule.
The empirical rule states that for a bell-shaped distribution:
- Approximately 68% of the data falls within 1 standard deviation of the mean.
- Approximately 95% of the data falls within 2 standard deviations of the mean.
- Approximately 99.7% of the data falls within 3 standard deviations of the mean.

Since our range is between -3 and 3 standard deviations from the mean, we can approximate that 99.7% of the daily phone calls answered by the receptionists will number between 26 and 56.

To translate the function (j(x) = |x| right 8 units and up 6 units, we need to modify the expression inside the absolute value function.

The translation right 8 units means we need to replace x with (x - 8).

The translation up 6 units means we need to add 6 to the entire expression.
