Therefore , the solution of the given problem of equation comes out to be another point on the line would be (3, 110).

In arithmetic equations, the identical sign (=) is used to denote the equivalence of two assertions. It is demonstrated that using mathematical methods, which have acted as manifestations of reality, it is feasible to compare different numerical factors. For fact, the equal sign splits the number 12 into two separate parts, even if the answer is y + 6 = 12. It is possible to determine how many letters are also present on either end of this character.

Here,

The equation for the total cost of a party at this venue for p people is:

C = 20p + 70

To graph this equation, you can plot two points and draw a line passing through them.

One point can be the y-intercept (0, 70), which represents the fixed event fee charged by the venue.

The second point can be any other point on the line. For example, when there are 3 people at the party, the total cost would be:

C = 20(3) + 70 = 110

So another point on the line would be (3, 110). Plotting these two points and drawing a line passing through them will give you the graph of the total cost as a function of the number of people at the party.

Answer: 678.58

Step-by-step explanation:

The solution to the given inequality 2x/2 - 5x -3 ≥ 0 is x ≤ - 3/8.

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

We have to solve 2x/2 - 5x -3 is greater than or equal to zero algebraically.

As per the question, we have inequality as follows:

The solution is Option C.

The value of the quadratic equation is 5x² + 2x = 7

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

5x² + 2x = 7  

On simplifying the equation , we get

Subtracting 7 on both sides of the equation , we get

5x² + 2x - 7 = 0   be equation (1)

Now , the roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

Substituting the values in the equation , we get

x = [ -2 ± √ ( 4 - 4 ( 5 ) ( -7 ) ] / 10

x = [ -2 ± √ ( 144 ) ] / 10

x = ( -2 ± 12 ) / 10

So , the two roots of the equation are

x = ( -2 + 12 ) / 10

x = 10/10 = 1

And , x = ( -2 - 12 ) / 10

x = -14/10

x = -7/5

Hence , the roots of the quadratic equation are 1 and -7/5

The model product, P(16), predicts the number of moose to be 3545 in 1997 and 2970 in 2009.

The odds that a happening will happen or a claim will be true is measured by probability theory, a branch od arithmetic. The probability of an item is a number between 0 but also 1, where about 0 represents how frequently the event is to occurring and 1 represents certainty. A risk is a numerical illustration of the possibility that a specific occurrence will take place. Probabilities may be expressed as percentages ranging from 0percent to 100% as well as from 0 to 1. the ratio of the number of outcomes to the proportion of occurrences in a whole set of equally plausible options that lead to a specific occurrence.

given

We'll choose x on the graph to represent the number of years since 1990 and y to represent the number of moose.

On the graph, there are two points: (4, 4290) and (8, 3850)

We can determine the slope of this line using the slope formula (m = [y2 - y1]/[x2 - x1]):

Replacement: m = (3850 - 4290)/(8 - 4)

m = -440/4 Solve the parenthesis's subtraction puzzles.

m = -110 Reduce the percentage

Since we know the line's slope, we can apply the point-slope formula (y - y1 = m[x - x1]) to determine the line's equation.

P(16) = 2970

Dan spent 1.25 at each table.

The formula used to solve this problem is m = 16 - 6/8. The calculation is as follows: 16 is the total amount of money Dan spent, 6 is the admission fee, and 8 is the number of tables. The equation is set up to find the amount of money Dan spent at each table. Taking the total amount of money spent, 16, and subtracting the admission fee, 6, leaves us with 10. We then divide this amount, 10, by the number of tables, 8, to find the amount of money spent at each table, which is 1.25. Therefore, Dan spent 1.25 at each table.

Answer:

The area of the region inside both the square and the rectangle is 37 square units.

Step-by-step explanation:

The area of the region inside both the square and the rectangle can be found by subtracting the areas of the four triangles outside the square from the area of the rectangle.

The area of the rectangle is 4 * 8 = 32 square units. The area of each triangle can be found using the formula for the area of a triangle, which is (base * height) / 2. The base of each triangle is half the length of the side of the square, which is 5 / 2 = 2.5 units. The height of each triangle is the difference in height between the rectangle and the square, which is 4 - 5 = -1 unit. The area of each triangle is (2.5 * -1) / 2 = -1.25 square units. The area of the four triangles outside the square is 4 * -1.25 = -5 square units.

The area of the region inside both the square and the rectangle is 32 + 5 = 37 square units.

The distribution is b) skewed.

The sum of the probabilities is: 1

In a binomial distribution, p represents the probability of success. Success in the sense that the event of interest happens. In the model presented, the probability of success p is 0.4 since we are informed that 40% of adults watch a particular television show.

The next quantity of significance in a binomial model is the number of independent trials, n.

In our case there are 6 independent trials since we are told that 6 adults were selected at random. If we let the random variable K denote the number of adults out of the 6 who watch the television show, then K is a binomial random variable with parameters;

n = 6 and p = 0.4

A binomial distribution is only symmetric when either p is 0.5 or n is large. In the presented scenario none of these conditions is met since p is 0.4 while n is just 6 which is relatively small.

Thus we conclude that the distribution is not symmetric but rather skewed.
