Which of the point of blow doesn't lie on the curve y = x^2​

The effect of eliminating a redundant constraint from a linear programming model depends on the specifics of the model and the constraint in question. It is important to analyze the model carefully to determine the effect that eliminating a constraint would have on the optimal solution.

No effect: If the constraint was indeed redundant, meaning that it did not affect the optimal solution, then eliminating it would have no effect on the optimal solution.

Improved solution: If the constraint was affecting the optimal solution, then eliminating it might result in a better solution. For example, if the constraint was limiting the feasible region of the solution, then eliminating it might expand the feasible region and result in a better solution.

Different solution: If the constraint was affecting the optimal solution, then eliminating it might result in a different solution. For example, if the constraint was forcing the optimal solution to go through a particular point, then eliminating it might result in a different solution.

Answer:

x = 115°

y = 50°

Step-by-step explanation:

it is an isosceles triangle, the angles at the base are congruent, x is the opposite angle of 115°, therefore the same value, to find y we subtract the two 65° angles from the sum of the internal angles of the triangle (180°) and we have 50 ° which is the value of Y, look at the figure to understand better

The sine of the complementary angle of 68° is 0.375.

Two angles are called complementary when their measures add to 90 degrees. Two angles are called supplementary when their measures add up to 180 degrees.

The complementary angle of 68° is calculated as;

θ = 90 - 68°

θ = 22°

sin (22° ) = 0.375

Answer:

The length is 52 meters and the width is 23 meters.

Step-by-step explanation:

Let l stand for length, and w stand for width.

l = 2w + 6

The length is 6 more than twice the width.

2l + 2w = 150

Twice the length plus twice the width is the perimeter of a rectangle.

2(2w + 6) + 2w = 150

4w + 12 + 2w = 150

6w + 12 = 150

6w = 138

w = 23

l = 2(23) + 6

l = 46 + 6

l = 52

Step-by-step explanation:

The probability of getting all 8 questions correct is 1/4096 or approximately 0.024%.

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

The probability of getting a True/False question correct is 1/2, since there are only two possible answers. The probability of getting a multiple-choice question correct is 1/4 since there are four possible answers.

So, for the first 4 True/False questions, the probability of getting them all correct is (1/2)⁴ = 1/16.

For the last 4 multiple-choice questions, the probability of getting them all correct is (1/4)⁴ = 1/256.

The total probability of getting all 8 questions correct is the product of the probabilities of getting each set of questions correct:

(1/16) x (1/256) = 1/4096

So, the probability of getting all questions correct is 1/4096 or about 0.024%.

the width of the frame is 0.806 inches.

The area is the entire amount of space occupied by a flat (2-D) surface or an object's form. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a form on paper is the area that it occupies.

Given this, Travis decided to make a frame for his birthday. The frame will be cut out of a piece of steel, and the final area of the frame should be 30in².

Since,

Area of frame = total area - cut out area

In our case, it is given that,

Total area = (11+2x)(6+2x)in²

cut out area = 11*6 = 66

So,

30 = (11+2x)(6+2x) - 66  

(11+2x)(6+2x) = 96

66 + 12x +22x +4x² = 96

The probability of a day in which the company receives 6 or more complaints is 0.3721 likely, or about 37.21%.

A subfield of mathematics called probability is concerned with the investigation of uncertain events. It is the measure of the likelihood or chance of an event occurring, expressed as a number between 0 and 1. The higher the probability, the more likely it is that the event will occur.

Given that the number of complaints per day follows a Poisson distribution with a rate parameter λ = 5.

Assume X is a random variable that represents the daily complaint rate.

The probability of receiving 6 or more complaints can be calculated as follows:

we can calculate the probability of X being less than 6 complaints per day as follows:

P(X < 6) = F(5) = e^(-λ) * Σ(λ^k / k!, k=0 to 5)

where e is the base of the natural logarithm, Σ denotes the sum from k=0 to 5, and k! denotes the factorial of k.

Substituting the value of λ = 5, we get:

P(X < 6) = e^(-5) * Σ(5^k / k!, k=0 to 5)

= 0.0337 + 0.1404 + 0.1755 + 0.1463 + 0.0916 + 0.0404

= 0.6279

Therefore, the probability of receiving 6 or more complaints in a day is:

The least common multiple of 3 and 5 is 15, so we convert 5 to 15/3.So the answer is 5/3.

The calculation in fractions:

1/3 of 20 = (1/3) * 20 = 20/3

5 subtracted from 1/3 of 20 = 20/3 - 5

To simplify the expression 20/3 - 5, we need to subtract 5 from 20/3 by finding a common denominator between 5 and 20/3. The least common multiple of 3 and 5 is 15, so we convert 5 to 15/3:

20/3 - 5 = 20/3 - 15/3 = (20 - 15)/3 = 5/3

So the answer is 5/3.

Fractions are a way of representing numbers as ratios of two integers. The top number of a fraction is called the numerator, and the bottom number is called the denominator.

Step-by-step explanation:

The probability of an event for rolling a die P(E) is 1/2.

What is the probability of an event?

The probability of an event is a number (always positive) that expresses the likelihood that the event will occur. The likelihood that an event will occur falls between zero and one. A certain occurrence has a probability of one while an impossible event has a chance of zero. As implied by its name, probability deals with uncertainty.

Given, E be the event defined as {3,4,6}

So, the total number of an event E, n(E) = 3

For a die, total events are {1,2,3,4,5,6}

So, the total number of rolls of a die event, n(T) = 6

Then,

P(E) = [tex]\frac{n(E)}{n(T)} = \frac{3}{6} = \frac{1}{2}[/tex]

So, the required value of P(E) is 1/2.

The farmer requests that the pen's length be 20 feet longer than its breadth. If we use the symbol w to indicate width. The length would then equal w + 20.

You play the part of a middle schooler who is attempting to make your family's farm profitable in Farmer Math.

The challenge first asks us to determine the longest length given that the fencing will not exceed 100 feet.

We are aware that a rectangular area's perimeter is 2l + 2w (where l is the length and w the width)

Therefore, 2l + 2w 100 would be required for the fencing.

In order to solve for w, we will use the values for l and w that we mentioned in the beginning:

2l + 2w ≤ 100

2(w+20) +2w ≤ 100

2w + 40 +2w ≤ 100

4w ≤ 100 - 40

4w ≤60

w ≤ 15

The breadth must therefore be less than or equal to 15.

The longest length is achieved when the width is at its greatest value because the length is 20 feet greater than the width.

This makes the length at w = 15 the longest it can possibly be, at 35.

The area of the rectangle would be equal to the sum of the areas of these 12 squares.

The area of a rectangle is a measure of the amount of space it covers. It is calculated by multiplying the length and the width of the rectangle.

For a rectangle with sides of 3 cm and 4 cm, the area can be found by multiplying 3 by 4. The formula for finding the area of a rectangle is

=> A = l * w,

where l is the length and w is the width.

So, for the rectangle with sides 3 cm and 4 cm, the area would be

=> A = 3 * 4 = 12 square centimeters.
