How is a system of two linear inequalities in two variables different from a system of two linear equations in two variables?
Answer:
A system of two linear inequalities in two variables is a set of two linear inequalities that involve two variables, such as x and y. A system of two linear equations in two variables is a set of two linear equations that involve two variables, also typically x and y.
There are several key differences between a system of two linear inequalities in two variables and a system of two linear equations in two variables:
Inequalities use symbols such as "less than" or "greater than" to indicate the relationship between the variables, whereas equations use the equal sign (=).
The solution to a system of linear inequalities is a region in the coordinate plane, whereas the solution to a system of linear equations is a single point.
The solution to a system of linear inequalities is found by graphing the inequalities on the coordinate plane and finding the region where they intersect, whereas the solution to a system of linear equations is found by solving the equations for the values of the variables.
The solution to a system of linear inequalities may include an infinite number of points, whereas the solution to a system of linear equations is always a finite number of points.
Overall, the main difference between a system of two linear inequalities in two variables and a system of two linear equations in two variables is the way in which the solutions are represented and found.
Can a triangle be formed with side lengths 15, 7, and 6? Explain
Answer:no
Step-by-step explanation:
There is a property with triangles that the sum of two sides of a triangle should always be greater than the 3rd side.
Here if we take the two smaller sides their sum is 7 + 8 = 15 which is equal to the third side.
So it is not possible to construct a triangle with sides 7, 8, and 15 respectively.

The given statement:
"the sum of a number and 10.7 is at most −3.2"
Is equivalent to the following inequality:
x + 10.7 ≤ -3.2
How to write the inequality?Here we have the following statement:
"the sum of a number and 10.7 is at most −3.2"
So let's define the variable "x" as "the number", we know that the sum between x and 10.7 is at most -3.2, we can say that the sum is equal to or smaller than -3.2
In that case, the symbol we need to use is: ≤
Then the inequality is:
sum ≤ -3.2
x + 10.7 ≤ -3.2
That is the statement written as an inequality.

10% of the time, the population mean will go below $1,500 or exceed $2,100.
Given that,
Assume that we have data on the annual spending on apparel of a sample of families. The probability that the population mean will fall below $1,500 or rise over $2,100 is ________% if we are 90% positive that the genuine population mean will be between $1,500 and $2,100.
We have to fill the blank.
We know that,
90% of the time, the real population mean will fall in the range of $1,500 and $2,100.
The genuine population mean will therefore most likely fall between $1,500 and $2,100, with a 90% probability.
So, the probability that it will fall outside of this range (i.e., be either less than $1,500 or beyond $2,100) is 100-90, or 10%.

The force “F” (in pounds) needed on a wrench handle to loosen a certain bolt varies inversely with the length “L” (in inches) of the handle. A force of 35 pounds is needed when the handle is 6 inches long. If a person needs 25 pounds of force to loosen the bolt, estimate the length of the wrench handle. Round answer to two decimal places if necessary.
______ inches.
The length of the wrench handle 8.4 inches.
What is length?
Distance is measured in length. Length has the dimension of distance in the International System of Quantities. The majority of measurement systems choose a base unit for length from which all other units are derived. The metre serves as the foundational unit of length in the International System of Units.
f = k/l
35 = k/6
k = 210
f = 210/l
25 =210/l
l = 8.4 inches
The length "L" (in inches) of a wrench handle has an inverse relationship with the force "F" (in pounds) required to remove a certain bolt. In the case of a handle that is 6 inches long, 35 pounds of power is required. The length of the wrench handle if the bolt needs to be loosened with 25 pounds of force is 8.4 .

The months when the temperature will be 0 °C are May and August.
What is a trigonometric function?A trigonometric function is a function that has the trigonometric ratios.
What is temperature?Temperature is the degree of hotness or coldess of a body.
How to find the months in which the temperature is zero degrees?Since the average monthly temperature of a particular city is T(m) = 10cos(πm/6) + 5 where m = number of months of year and January begins at m = 0.
To find the number of months in which the temperature would be 0°C. This means T(m) = 0.
So, T(m) = 10cos(πm/6) + 5
0 = 10cos(πm/6) + 5
-10cos(πm/6) = 5
cos(πm/6) = 5/10
cos(πm/6) = -0.5
cos⁻¹cos(πm/6) = cos⁻¹(-0.5)
(πm/6) = π - π/6 or (πm/6) = 3π/2 - π/6 (since cos is negative int he second and third quadrant respectively)
πm/6 = 5π/6 or πm/6 = 8π/6
⇒ m = 5π/6 × 6/π or m = 8π/6 × 6/π
⇒ m = 5 or m = 8
Since m = 5 is May and m = 8 is August,
The months when the temperature will be 0 °C are May and August.

2: One that would make less lemonade but taste the same as the original recipe.
3: One that would have a stronger lemon taste than the original recipe
4: One that would have a weaker lemon taste than the original recipe.
Since the lemonade recipe calls for the juice of 5 lemons, 2 cups of water, and 2 tablespoons of honey we can use mathematical operations to make different lemonades with the following recipes:
1) To make more lemonade taste the same as the original, we can use the multiplication operation on the above recipe as follows:
Lemons = 10
Cups of water = 4
Tablespoons of honey = 4
2) To make less lemonade taste the same as the original recipe, we can use the division operation as follows:

In which the coefficients are given as follows:
m is the slope.b is the y-intercept.For item 1, the points are given as follows:

The Central Limit Theorem inform us that because the pattern length has a tendency to infinity, the of the distribution of pattern method methods the ordinary distribution.
The regulation of huge numbers has a completely vital position in possibility and statistics. It states that in case you repeat an test independently a huge variety of instances and common the result, what you got must be near the predicted value.
