What is  linear equation?

An algebraic equation with simply a constant and a first- order( direct) element, similar as y = mx b, where m is the pitch and b is the y- intercept, is known as a linear equation.

                         The below is sometimes appertained to as a" direct equation of two variables," where y and x are the variables. Equations whose variables have a power of one are called direct equations. One illustration with only one variable is where layoff b = 0, where a and b are real values and x is the variable.

The midnight temperature is 5 °C and the temperature is decreasing at the rate of 2°C per hour.

If t is the hours past midnight then after t hours the temperature will be ( 5 - 2t ).

The inequality that represents t, the number of hours past midnight, when the temperature was cooler than -4 degrees celsius( 5 - 2t ) < - 4

What is  inequality?

The term "inequality" is used in mathematics to describe a relationship between two expressions or values that is not equal to one another. Inequality results from a lack of balance. When two quantities are equal, we use the symbol '=', and when they are not equal, we use the symbol. If two values are not equal, the first value can be greater than (>) or less than (), or greater than equal to () or less than equal to ().

The midnight temperature is 5 °C and the temperature is decreasing at the rate of 2°C per hour.

If t is the hours past midnight then after t hours the temperature will be

The required area of the given triangle is 63 ft² respectively.

A triangle is a 3-sided polygon that is occasionally (though not frequently) referred to as the trigon.

There are three sides and three angles in every triangle, some of which may be the same.

A unique triangle and plane (i.e., a two-dimensional Euclidean space) are determined by any three non-collinear points in Euclidean geometry.

In other words, every triangle is contained in a plane, and there is only one plane that contains that triangle.

Area of a triangle:

1/2 * b * h

Now, insert values as follows:

A line plot is a type of graph that displays data points as dots or markers connected by straight lines. The resultant line plot is given below.

A line plot, also known as a dot plot, is a simple way to display data that consists of a number of discrete points. It is a one-dimensional graph that uses dots or Xs to represent individual data points. Each dot or X represents a single data point, and the number of dots or X's at a given location on the line represents the frequency or count of that data point.

Step-by-step explanation:

The distance between your location and the epicenter is just slightly larger than the maximum distance that the earthquake can be felt (76 miles), so you would be able to feel the earthquake.

A triangle is a polygon with three sides and three angles. The sum of the angles in a triangle is always 180 degrees. There are different types of triangles such as equilateral, isosceles, scalene, right-angled, obtuse-angled, and acute-angled triangles. Triangles are used in geometry and other fields of mathematics to solve problems related to areas, angles, and side lengths.

Here,

Yes, you feel the earthquake.

To see why, imagine drawing a circle around the epicenter with a radius of 76 miles. This circle represents the maximum distance that the earthquake can be felt. Then, draw a line from the epicenter to your location. This line represents the distance between you and the epicenter.

To determine whether you feel the earthquake, we need to calculate the distance between your location and the epicenter using the Pythagorean theorem:

distance = √(65² + 40²)

We would predict using the random sample that 175 students at the school like math.

A confidence interval is a range of values that, with a certain degree of certainty, is likely to contain the real value of a population parameter. In most cases, the level of confidence is stated as a percentage, such as 95% or 99%, and it indicates the likelihood that the parameter's actual value falls within the range. In statistics, confidence intervals are frequently used to calculate an estimate of a population parameter's value from a sample of data. A confidence interval, which offers a range of likely values for the population parameter, is constructed using the sample statistics and the variability of the data.

Given that, 14 out of 20 students like math.

Using proportions we have:

The number of bags that have zips on them is 28.

To solve this problem, we can use the principle of inclusion-exclusion.

First, we know that the total number of bags is 110.

Next, we know that 24 of the bags have neither zips nor buttons. Therefore, the number of bags that have either zips or buttons is 110 - 24 = 86.

We also know that 32 of the bags have buttons but no zips, and 28 of the bags have zips but no buttons.

To find the number of bags that have both zips and buttons, we can subtract the number of bags that have only buttons from the total number of bags with zips, or vice versa:

Number of bags with both zips and buttons = (Number of bags with zips) + (Number of bags with buttons) - (Number of bags with either zips or buttons)

Number of bags with both zips and buttons = 28 + 32 - 86 = -26

This result is clearly nonsensical, so we can conclude that there are no bags with both zips and buttons.

Therefore, the number of bags that have zips on them is simply the number of bags with zips but no buttons, which is 28.

The binomial theorem is a mathematical formula that provides a way to expand the power of a binomial expression, which is an expression that consists of two terms.

(a + b)ⁿ = C(n,0)aⁿ + C(n,1)[tex]a^(n-1)[/tex]b + C(n,2)[tex]a^(n-2)[/tex]b² + ... + C(n,n-1)a[tex]b^(n-1)[/tex] + C(n,n)bⁿ

where C(n,r) is the binomial coefficient, given by:

C(n,r) = n! / (r! * (n-r)!)

In this case, n = 4 and we want to find the 5th term, which means we want the coefficient for the term with a³b. Using the formula, we can see that the coefficient for this term is:

C(4,3) = 4! / (3! * (4-3)!) = 4

The probability that Julian will roll a 3 on the next roll is approximately 16.67%. The probability of rolling a 3 on a normal 6-sided die is independent of the previous rolls. This means that regardless of the outcomes of Julian's previous rolls, the probability remains the same.

Explanation

On a 6-sided die, there is 1 favorable outcome for rolling a 3 (the number 3 itself) out of 6 possible outcomes (1, 2, 3, 4, 5, and 6).

To find the probability, you can use the formula:

Probability = (Number of favorable outcomes) / (Total number of outcomes)

In this case:

Probability of rolling a 3 = 1 (favorable outcome) / 6 (total outcomes)

Probability of rolling a 3 = 1/6 ≈ 0.1667 or 16.67%

So, the probability that Julian will roll a 3 on the next roll is approximately 16.67%.

What is a triangle ?

A triangle is a polygon with three sides, three vertices, and three angles. The sum of the interior angles of a triangle is always 180 degrees. Triangles can be classified based on their side lengths and angle measures.

In a right-angled triangle, the sum of the two acute angles is always equal to 90 degrees. Therefore, we can find the measure of angle B in the right-angled triangle ACB by subtracting the measure of angle A and the right angle from 90 degrees.

Given that [tex]\angle A = 27^\circ[/tex], we can find the measure of angle B as follows:

[tex]\angle B = 180^\circ - \angle A - \angle C[/tex]

Since the triangle is right-angled at C, we know that [tex]\angle C = 90^\circ[/tex]. Therefore, we can substitute the values of [tex]\angle A[/tex] and [tex]\angle C[/tex] in the equation above to get:

[tex]\angle B = 180^\circ - 27^\circ - 90^\circ[/tex]
