|3t+6| =9
A. n= -5
B. n= 1
C. n= -1 or 1
D. n= -5 or 1
Answer:
C, n= -1 or 1.
Step-by-step explanation: The bars around 3x+6 are absolute value bars (| |), meaning that whatever lies inside of them will turn positive. An example: |-9| ➡️ 9. So, since we do have the absolute value bars, multiplying 3 by -1 would not effect the equation. So therefor we could use a regular 1 or a negative one to make the equation equal to 9.

There were 17 unny day thi year, which wa 18 fewer than lat year. Two year ago , there were three time a many unny day a there were thi year. How many unny day were there in all three year?
The total number of sunny days for the three years is 103 days.
This year there were 17 sunny days.
There were 17 sunny days this year, 18 fewer than last year. This is to mean that, last year, sunny days were 18 days more than this year, Which can be found by;
18+17 = 35 sunny days
Sunny days two years ago were three times the sunny days this year which is;
3×17 = 51 sunny days
Therefore, the total number of sunny days for the three years is calculated by adding the total number of sunny days for the three years:
17 + 35 + 51 = 103 sunny days

Last summer, Sheila decided to measure change in a swimming pool's
water level each week. There was a hot and dry spell that lasted 4
weeks and the water level dropped the following amounts each week
Sheila measured the level: 8 millimeters in the first week, 5 millimeters
in the second week, 12 millimeters in the third week, and 5 millimeters
in the fourth week. Express the total gain/loss of water over the 4
weeks as an integer
Sheila measured the water level in the swimming pool every week for 4 weeks and found that the water level decreased by 8 millimeters in the first week, 5 millimeters in the second week, 12 millimeters in the third week and 5 millimeters in the fourth week. The net result was a loss of 10 millimeters of water over the 4 week period.
Sheila wanted to track the changes in the water level of a swimming pool over time. She measured the level every week for 4 weeks. In the first week, the water level dropped by 8 millimeters. In the second week, the level dropped by 5 millimeters. In the third week, the level dropped by 12 millimeters. Finally, in the fourth week, the level dropped by 5 millimeters. The net result of these measurements was a loss of 10 millimeters of water over the course of the 4 week period. This indicates that the hot and dry spell had a negative effect on the water level in the pool.
Total Water Loss = 8 millimeters + 5 millimeters + 12 millimeters + 5 millimeters = 30 millimeters
Total Water Gain = 0 millimeters
Net Loss = Total Water Loss - Total Water Gain = 30 millimeters - 0 millimeters = -10 millimeters

A triangle has two sides of length 8.3 and 3.4. What compound inequality describes the possible lengths for the third side, x?
Using Pythagoras theorem the compound inequality for the possible length is 7.6 ≤ x ≤ 9
Pythagoras TheoremPythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangle have been named Perpendicular, Base and Hypotenuse. Here, the hypotenuse is the longest side, as it is opposite to the angle 90°.
To find the possible value for the third side, we have to use Pythagoras formula which is given as;
x² = y² + z²
In the first scenario, we would assume the third side is the hypothenuse
x² = 8.3² + 3.4²
x = 9
In the second scenario, we would assume the third side is one of the legs of the triangle and the formula will change to
8.3² = y² + 3.4²
y² = 8.3² - 3.4²
y = 7.6

How do you solve for y in a triangle?
Either Pythagorean Theorem or the Law of Cosines is used to solve for y in a triangle, you can use either of these equations.
The Pythagorean Theorem states that the sum of the squares of the two shorter sides of the triangle is equal to the square of the longest side. This is written as:
a2 + b2 = c2,
where a and b are the lengths of the two shorter sides, and c is the length of the longest side. In this equation, y is the length of the longest side.
The Law of Cosines states that:
a2 = b2 + c2 - 2bc cos A
where A is the angle opposite side a. In this equation, y is side a.
Therefore, to solve for y in a triangle, you can use either the Pythagorean Theorem or the Law of Cosines, depending on the information given.

What does Squaring mean ?
In mathematics, a square is the result of multiplying a number by itself. The verb "to square" is used to denote this operation. Squaring is the same as raising to the power 2, and is denoted by a superscript 2; for instance, the square of 3 may be written as 32, which is the number 9.
When you multiply an integer (a “whole” number, positive, negative or zero) times itself, the resulting product is called a square number, or a perfect square or simply “a square.” So, 0, 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, and so on, are all square numbers.

The slope of the line y =3x(1 ,3) is 3.
Describe slope.The ratio of how much y grows as x grows by a certain amount is known as a line's slope. The slope of a line indicates how steep it is, or how much y rises as x rises. Anywhere along the line, the slope remains constant (the same). In math, we frequently want to quantify the steepness. Slopes B and C are clearly higher than slope A. While slope A is just four units high, they are both seven units high. Therefore, it would seem that height and steepness are related.

how to determine sample size needed for confidence intercal when population standard deviation not known
When the population standard deviation is not known, the sample size needed for a confidence interval can be determined using the t-distribution.
The t-distribution is used to calculate the margin of error, which is the amount of variation that is allowed in the sample results. The sample size needed for a confidence interval is determined by calculating the critical value of the t-distribution for a given level of confidence and degree of freedom. The degree of freedom is the number of independent observations in the sample minus one.
The confidence level determines the critical value of the t-distribution, which is used to calculate the margin of error. The sample size is then calculated by dividing the margin of error by the desired confidence level. This method allows us to determine the sample size needed for a confidence interval even when the population standard deviation is unknown.

To find the sum of roots, we need to factor the equation :
x2 + 5x + 6 = 0
x2 + 3x + 2x + 6
= 0
x(x + 3) + 2(x + 3)
= 0
(x + 3)(x + 2) = 0
x = -3, -2
Sum of Roots = -3 + (-2) = -5
x2 + 5x + 6 = 0
To find the sum of roots, we need to factorize the given equation. To do that, we can divide the equation into two parts, x2 + 3x and 2x + 6. We can factorize the first part as x(x + 3) and the second part as 2(x + 3). Then, we can multiply both parts to get the factorized equation, (x + 3)(x + 2) = 0. We can solve this equation to get the roots, x = -3 and -2. Finally, we can add both roots to get the sum of roots, -3 + (-2) = -5.

The discriminant of a quadratic equation is a numerical value that can be used to determine the nature of its roots. The discriminant is equal to the expression (b^2 - 4ac) where a, b, and c are the coefficients of the equation. In this case, the equation is 2x² 5x 3 0. We can identify the coefficients of the equation as a = 2, b = 5, and c = 3. Using the formula, the discriminant is equal to (5^2 - 4(2)(3)) = 25 - 24 = 1. This means that the equation has two real and equal roots, as the discriminant is equal to zero. This can be seen by factoring the equation, which gives us (2x - 3)(x + 1) = 0.

A quadratic equation is a second-order algebraic equation in x. The quadratic equation in standard form is ax2 + bx + c = 0. where a and b are the coefficients, x is the variable, and c is the constant term. The first condition of the quadratic equation is that the coefficients of x² are non-zero terms (a ≠ 0).
