Inequality Interval Notation Graph

Sajan Rai

Solve the inequalities below. Write the solution set in interval notation and graph the solution.

8x−12>158x-12>15

Solution:

Interval notation for the solution:

(-∞,5/8) U (5/8, ∞)

To graph the solution, we need to find the points that make the inequality true and shade the region that corresponds to these points. On the number line, we can start by finding x values that make the inequality equal to zero:

8x - 12 = 0

x = 12/8 = 3/2

and

15 - 8x = 0

x = 15/8 = 9/4

Next, we need to test values that are less than 3/2 and greater than 9/4 to determine the direction of the inequality. If the inequality is true for values less than 3/2, then we shade the region to the left of 3/2. If the inequality is true for values greater than 9/4, then we shade the region to the right of 9/4. In this case, since the inequality is "greater than," the shading goes to the right of 9/4 and to the left of 3/2.

A crate is 3/4 yard long and 2/4 yard wide. The crate is also 2 feet tall. What is the area of the top of the crate?

(please explain the answer step by step if possible.)

Answers

Answer:

The area of the top of the crate can be found by multiplying the length by the width.

First, we need to convert all units to the same unit, either yards or feet. We will convert the length and width to yards:

        3/4 yard = 9/12 yards

        2/4 yard = 6/12 yards

    2. Now we can find the area by multiplying the length by the width:

     Area = 9/12 yards * 6/12 yards = (9/12) * (6/12) = 3/4 * 1/2 = 3/8                         yards^2

So, the area of the top of the crate is 3/8 yards^2.

What is Strictly convex function?

A real-valued function is said to be convex if the line segment connecting any two points on its graph falls above the graph connecting the two points. A function is convex if and only if its epigraph is a convex set.

Since f"(x) > 0 for all x in (0,2), it follows that f is a strictly convex function on that interval, meaning that its second derivative is positive and its first derivative is increasing.

If f is a strictly convex function on [0,2], then f(2-x) is a strictly concave function on [0,2]. The sum of a strictly convex and a strictly concave function is also a strictly convex function.

Therefore, since f''(x) = f(x) + f(2-x), it follows that f''(x) is a strictly convex function on [0,2], which means that its first derivative is increasing.

Answers

The mean is 14.7, the median is 16, and the mode is 16.

To find the mean, we need to calculate the sum of all the data values and divide it by the total number of observations.

The sum of the data values is:

14 x 14 + 15 x 11 + 16 x 23 + 17 x 10 + 18 x 13 = 196 + 165 + 368 + 170 + 234 = 1043

The number of observations is:

14 + 11 + 23 + 10 + 13 = 71

The mean is calculated as follows,

1043 / 71 = 14.7 (rounded to one decimal place)

The median is the central value in the data collection. To find the median, we need to arrange the data values in ascending order and find the middle value. In this case, we have an odd number of observations, so the median is simply the middle value.

14, 14, 15, 15, 16, 16, 16, 16, 16, 16, 16, 17, 17, 18, 18, 18

At Cookout, 4 burgers and 3 containers of fries cost $16.40. Your finger rubbed off part of your receipt but you could see that each burger was $3.20. Find the cost of a container of fries. Explain your thinking.

Answers

The required container of fries costs $1.20, as er the given condition

What are equation models?

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Let's call the cost of a container of fries "x".

We know that 4 burgers cost 4 * $3.20 = $12.80.

So the total cost of burgers and fries is $12.80 + 3x = $16.40.

Subtracting the cost of the burgers from both sides:

3x = $16.40 - $12.80 = $3.60

Dividing both sides by 3:

x = $3.60 / 3 = $1.20

If the hand moves from the 12 o'clock position to the 5 o'clock position, it has traveled a distance is 9.5 cm.

What is the circumference of the circle?

The Circumference of a circle is basically the perimeter of the circle. It is given as (2×π×r) or (π×d).

The hand on a circular clock moves along the circumference of the circle, and the length of the circumference of a circle is given by the formula:

C = 2 * π * r

where C is the circumference, π is Pi (approximately equal to 3.14), and r is the radius of the circle.

In this case, the radius of the circle is half the length of the hand, or 12cm / 2 = 6cm.

So the circumference of the circle is:

C = 2 * π * 6 = 12 * π

Since the hand moves from the 12 o'clock position to the 5 o'clock position, it has traveled an angle of 5 * (360/12) = 150 degrees.

To find the distance traveled along the circumference, we need to multiply the circumference by the fraction of the circle traveled, which is equal to the angle in radians divided by 2π.

To convert from degrees to radians, we can use the formula:

radians = degrees * (π / 180)

So, the distance traveled by the hand is:

distance = C * (150 * (π / 180)) / (2 * π) = 12 * (150 * (π / 180)) / 2 = 9.5 cm (rounded to the nearest cm)

hence, if the hand moves from the 12 o'clock position to the 5 o'clock position, it has traveled a distance is 9.5 cm.

in a convergent geometric series the sum to infinity is 18 and the sum of the first four terms is 130÷9 calculate the common ratio​

Answers

The common ratio is approximately -0.6.

Step by step explanation

Let the first term in the geometric series be "a" and the common ratio be "r". Then, the formula for the sum to infinity of a geometric series is:

S = a / (1 - r)

And the formula for the sum of the first n terms of a geometric series is:

Sn = a * (1 - r^n) / (1 - r)

So, using the information given:

18 = a / (1 - r)

And:

130/9 = a * (1 - r^4) / (1 - r)

Solving for "r" using these two equations:

18 = a / (1 - r) ==> a = 18 * (1 - r)

130/9 = a * (1 - r^4) / (1 - r) ==> 130/9 = 18 * (1 - r) * (1 - r^4) / (1 - r) ==> 130/9 = 18 * (1 - r^4)

Dividing both sides by 18:

7/5 = (1 - r^4)

So:

r^4 = 1 - 7/5 = -2/5

Taking the fourth root of both sides:

r = (-2/5)^(1/4)

Please answer my question. Find the SA (surface area) of the composite shape. Round to the nearest tenth. Please help.

Answers

The total surface area of the composite shape is 488.7 in².

What is a composite shape?

A composite shape is a shape that was produced from two or more fundamental shapes. Composite shapes are also referred to as compound and complex shapes frequently. Every day, composite shapes are around us.

The given composite shape can be divided into multiple shapes, to find the area easily.

For the given question, we can see that the lower portion of the shape is a cuboid and the upper portion is half of the cylinder cut vertically.

We find the areas of the figures separately.

Area of cuboid

Length l = 6 in.

Breadth b = 10 in.

Height h = 8 in.

Area = Area of each faces =  2(lb) + 2(bh) +2(lh)

                                             = 2(6*10) + 2(10*8) + 2(6*8)

                                               = 2*60 +2* 80 + 2* 48

                                                 = 376 in²

Area of cylinder

Radius of semicircles r = 5 in.

Height of cylinder h = 6 in.

Area =  Area of semicircles + Area of half of the curved surface

        =  2 *1/2 * πr² + 1/2 * 2πrh =  πr² + πrh = 3.14 * 5² + 3.14 * 5 * 6

                                                                 = 172.7 in²

The total surface area of the composite shape = Area of cylinder + Area               of cuboid - Area of the common surface(rectangle)

                = 172.7  + 376 - (l *b) = 548.7 - ( 10*6) = 488.7 in²

Hence the total surface area of the composite shape is 488.7 in².

o^2 = ∑(x - u)^2 * p(x) = (0.5 - 2.25)^2 * 0.0625 + (2.5 - 2.25)^2 * 0.125 + (0.25 - 2.25)^2 * 0.25 + (0.25 - 2.25)^2 * 0.25 + (0.25 - 2.25)^2 * 0.25 = 0.5625

So, o = √0.5625 = 3.188

b. The sampling distribution of the sample mean x for a random sample of n=2 measurements from this distribution is given by:

x = (x1 + x2) / n = (2.25 + 2.25) / 2 = 2.25

As n approaches infinity, the sample mean x approaches the population mean u, and the distribution of x becomes more and more concentrated around u.

c. Yes, x is an unbiased estimator of u because its expected value is equal to the population mean: E(x) = u.

Find the zeros and give the multiplicity.
f(x) = x2(5x + 6)9(x − 8)2

Answers

Answer:

Zeroes & Multiplicity:

x = 0        :   Multiplicity = 2

x = -6/5   :   Multiplicity = 9

x = 8        :   Multiplicity = 2

Step-by-step explanation:

The equation provided is: [tex]f(x)=x^2(5x+6)^9(x-8)^2[/tex]

Factored Form:

We're given the polynomial in factored form, which just means the polynomial is broken down into each of its factors. This is a really convenient form to have a polynomial in as we can easily find the zeroes of the polynomial.

This is due to the Zero Property of Multiplication, which essentially states zero times any number results in zero. So we just have to set each factor equal to zero, and solve, since if one of the factors is zero, then the entire thing becomes zero.

So this gives us the following equations:

[tex]x^2=0\implies x = 0\\\\(5x+6)^9=0\implies x = -\frac{6}{5}\\\\(x-8)^2=0\implies x = 8[/tex]

Now for the multiplicity, we just look at the exponent of the factor we set equal to zero. So x^2 gives us a zero of x = 0, and the exponent is 2, which is also the multiplicity of this zero.

The (5x + 6)^9 gives us a zero of x = -6/5, and the exponent is 9, which is also the multiplicity of the zero. Same thing applies for the zero at x = 8, which has a multiplicity of 2.

What is the percent change from 82 to 67

Answers

First find the actual difference:

   82 - 67 = 15

Now divide that difference by the starting value (82 in this case):

    15 / 82 ≈ 0.182927

Convert that to a percent:

   0.182927 = 18.2927%

That's the percent change, a decrease of about 18.2927%

the confidence intervals for the situation is 46%

What is confidence interval?

A confidence interval (CI) for an unknown parameter in frequentist statistics is a range of estimations. The most popular confidence level is 95%, but other levels, such 90% or 99%, are occasionally used for computing confidence intervals. The fraction of related CIs over the long run that actually contain the parameter's true value is what is meant by the confidence level. The degree of confidence, sample size, and sample variability are all factors that might affect the width of the CI. A larger sample would result in a narrower confidence interval if all other factors remained constant. A wider confidence interval would also be required by a higher confidence level and would be produced by a sample with more variability.

the particular week that they had 50 patients the table shows the record numbers of dogs use the given data to complete the sample proportion.

Let's calculate the percentage or proportion of patients that were dogs:

p = (7 + 4 + 5 + 5 + 2)/50 = 23/50 = 0.46

Hence the confidence intervals for the situation is 46%

A park is in the shape of a rectangle 8 miles long and 6 miles wide. How much shorter is your walk if you walk diagonally across the park than along the two sides of it? Round to the nearest tenth if necessary.

Answers

You would need to walk 4 miles less if you walk along the diagonal rather than the two sides.

What is Pythagoras Theorem?

A key concept in mathematics is the Pythagorean Theorem, which describes the relationship between the sides of a right-angled triangle. Pythagorean triples are another name for the right triangle's sides. Here, examples are used to explain the theorem's formulation and proof.

The Pythagorean theorem is mostly used to determine a triangle's angle and the length of an ambiguous side. The base, perpendicular, and hypotenuse formulas can all be derived using this theorem.

Given that, park is in the shape of a rectangle 8 miles long and 6 miles wide.

The diagonal of the park is calculated using the Pythagoras theorem.

The Pythagoras theorem is given as:

c² = a² +b²

c² = 8² + 6²

c² = 64 + 36

c² = 100

c = 10

If you walk along the diagonal you need to walk 10 miles.

If you walk along the two sides the distance is:

d = 8 + 6 = 14 miles

Hence, the difference between the distance is:

14 - 10 = 4 miles.

Hence, you would need to walk 4 miles less if you walk along the diagonal rather than the two sides.
