The approximate critical value t0.15,10 using linear interpolation is 1.8162.
Using Appendix Table 5, we need to approximate the critical value t0.15,10. For this, we'll use linear interpolation.
First, locate the values in the table nearest to the desired critical value. In this case, we have t0.15,12 and t0.15,9. According to the table, these values are 1.7823 and 1.8331, respectively.
Now, we'll apply linear interpolation. Here's the formula:
t0.15,10 = t0.15,9 + (10 - 9) * (t0.15,12 - t0.15,9) / (12 - 9)
t0.15,10 = 1.8331 + (1) * (1.7823 - 1.8331) / (3)
t0.15,10 = 1.8331 + (-0.0508) / 3
t0.15,10 = 1.8331 - 0.0169
t0.15,10 ≈ 1.8162
So, the approximate critical value t0.15,10 using linear interpolation is 1.8162.

Now, evaluate the given equation
= 1/sin2x - cos2x/sin2x
use the formula of 1-cos2x and substitute in the above equation.
= (1-cos2x)/sin2x
we have the formula of sin2x=2sinxcosx and converting 1-cos2x as 2sin²x
Now, substitute in the above equation.
= (2sin²x)/2sinxcosx
By, canceling 2sinx in the numerator and denominator, we get
= sin(x)/cos(x)
= tan(x)

What are the 3 types straight line?
The 3 types straight line are
1. Slope-intercept form: y = mx + b
2. Point-slope form: y - y1 = m(x - x1)
3. Standard form: ax + by = c
1. Slope-intercept form: y = mx + b - This is the most common form of a straight line; it is composed of two parts: m (the slope of the line) and b (the y-intercept). To use this form, you need to know the slope (m) of the line and the y-intercept (b). From this information, you can calculate the equation of the line by substituting the values of m and b into the equation.
2. Point-slope form: y - y1 = m(x - x1) - This form of a straight line requires two points on the line and the slope of the line. To use this form, you need to know the two points on the line (x1, y1) and the slope of the line (m). Then, you can calculate the equation of the line by substituting the values of x1, y1 and m into the equation.
3. Standard form: ax + by = c - This form of a straight line is composed of three parts: a (the coefficient of x), b (the coefficient of y) and c (the constant). To use this form, you need to know the coefficients of x and y and the constant. From this information, you can calculate the equation of the line by substituting the values of a, b and c into the equation.

In how many ways can the digits in the number 9550000 be arranged
The number 9550000 can be arranged in a total of 8!/(4!4!) = 70 different ways.
What is digits?Digits are numerals or numbers used for counting, measuring, and representing quantities. They are the building blocks of mathematics, and are used to express amounts, relationships, and orders of magnitude. Digits are also used in computers and other digital devices to store and communicate information.
The 8 digits of 9550000 can be arranged using the formula for permutation: nPr = n!/(n-r)!
In this case, n = 8 and r = 8. So, the number of permutations of the 8 digits of 9550000 will be 8!/(8-8)! = 8!/(0!) = 8! = 40320.
However, we need to account for the fact that there are 4 zeros in the number 9550000. To do this, we need to divide the number of permutations by 4! (factorial of 4) to account for the 4 identical digits.
Therefore, the total number of ways the digits in the number 9550000 can be arranged is 40320/4! = 70.

The value of CE in the segment is 30 units.
The value of x in the segment is 1 units.
How to find the length in a line segment?A line segment is bounded by two distinct points on a line. Therefore, point D is located on the segment CE. Hence,
CD = 24 and DE = x
CE = 5x
Therefore, the measurement of the segment CE can be found as follows:
CE = CD + DE
5x = 24 + x
5x - x = 24
4x = 24
divide both sides of the equation by 4
x = 24 / 4
x = 6
Finally,
CE = 5(6) = 30
The segment XZ is bisected by the point Y. Hence,

A baker sells bread for $3 a loaf and rolls for $1 each. The baker needs to sell $27 worth of baked goods by

number of rolls sold.
The graph shows the different combinations of loaves of bread and rolls that the baker can sell in order to reach a total revenue of $27.
What is the slope-intercept form?
The slope-intercept form is a way of expressing a linear equation in the form of y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept is the point at which the line crosses the y-axis, meaning the point at which the line intersects the y-axis when x = 0.
The given equation is in the form of y = mx + b where y =27, m = 3 and b = 1, is a linear equation and it can be represented as a straight line in a coordinate plane.
To graph this equation, we can use the following steps:
Plot the y-intercept, which is the point where the line crosses the y-axis. In this case, the y-intercept is (0, 27) since when b = 0 and r = 0, the left side of the equation equals 27.Identify the slope, m = 3. This tells us that the line rises 3 units for every 1 unit it moves along the x-axis.Using the slope and y-intercept, pick a second point on the line and plot it. Connect the two points with a straight line. The graph will be a straight line passing through the point (0,27) and (5,15)The graph will be the line with equation y = 3x + 1, where x is the number of loaves of bread sold and y is the total cost of the bread.The graph shows the different combinations of loaves of bread and rolls that the baker can sell in order to reach a total revenue of $27.

What is constant of proportionality?When two or more parameters are either directly or indirectly proportional to one another, the relationship is written as a = kb or a = k/b, where k denotes the direction of the relationship between the two variables. The proportionality constant, k, is defined as follows.
The ratio of two proportional values at a constant value serves as the definition of the proportionality constant. When the product or ratio of two variables yields a constant, the relationship between the two is proportional.

What is the additive inverse of minus 13 7 by 8?
The additive inverse of -13 7/8 is +13 7/8.
The additive inverse of a number is the number that, when added to the original, equals zero. The additive inverse of -13 7/8 can be found by turning the sign of the original number into its opposite, which would be +13 7/8. This can be expressed mathematically using the formula a + (-a) = 0, where a is the original number.
When -13 7/8 is added to +13 7/8, the result is 0. This can be seen by calculation: -13 7/8 + 13 7/8 = -13 7/8 + 8/8 + 5/8 = -5/8 + 8/8 = 3/8 + 8/8 = 11/8 + 8/8 = 19/8 + 8/8 = 27/8 + 8/8 = 35/8 + 8/8 = 43/8 + 8/8 = 51/8 + 8/8 = 59/8 + 8/8 = 67/8 + 8/8 = 75/8 + 8/8 = 83/8 + 8/8 = 91/8 + 8/8 = 99/8 + 8/8 = 107/8 = 0.

How do you describe the motion of an object in terms of distance or displacement?
Distance is a measure of how far an object has traveled from a starting point. Displacement is the change in position from the starting point.
It is the total distance an object has moved and is the sum of all the displacements an object has made. The formula for calculating distance is distance = speed x time. For example, if a car has traveled at a speed of 50 km/h for 4 hours, then the distance traveled is 200 km (50 km/h x 4 h = 200 km).
Displacement is the change in position from the starting point. It is the shortest distance between the starting point and the final point and does not take into account the direction of motion. The formula for calculating displacement is displacement = final position – initial position. For example, if a car starts at point A and travels to point B, the displacement is the distance between A and B (B – A).
