A rational number that is located between -2 ¼ and -2.8 is -2.5.

To determine a rational number between -2 ¼ and -2.8, we need to find a number that is greater than -2 ¼ but less than -2.8.

First, let's convert -2 ¼ to decimal form. ¼ is equal to 0.25, so -2 ¼ can be written as -2.25.

Next, we compare -2.25 and -2.8 to find a number in between them. We can see that -2.25 is greater than -2.8.

Since -2.25 is greater than -2.8 and we want a number between them, we can choose a number that is smaller than -2.25. One such number is -2.5.

Therefore, the rational number -2.5 is located between -2 ¼ and -2.8. It is smaller than -2.25 but greater than -2.8, satisfying the condition of being between the two given numbers.

Answer:

Ok, a system of equations means that we have a given number of equations with the same solutions.

If we only have tables, this means that we need to have one table for each equation:

For example, if we are working only with two variables, x and y, in those tables we can see the pints (x, y) that belong to each equation.

Now, a point (x, y) will be a solution of the system of equations only if it belongs to the data table for each equation

This would mean that if we graph those data sets, the graphs will intersect at the point (x, y) that belongs to all the tables of data.

Other way may be using the data in the tables to construct the equations, but you said that you only want to use the tables, so this method can be discarded.

Step-by-step explanation:

The trapezoid is the only quadrilateral in the given list in which a diagonal does not always divide the quadrilateral into two regions of equal area.

This is because a trapezoid has two parallel sides of different lengths, so the diagonal that connects the non-parallel sides will not bisect the trapezoid's area. In contrast, a rhombus, square, rectangle, and parallelogram all have diagonals that bisect their areas, meaning that each half of the quadrilateral has an equal area.

In a trapezoid, a diagonal does not always divide the quadrilateral into two regions of equal area. Unlike squares, rectangles, and parallelograms, where diagonals create congruent triangles, trapezoids do not guarantee this property. In a trapezoid, diagonals can create triangles with different areas due to the uneven side lengths and angles. Thus, the trapezoid is the quadrilateral in which a diagonal may not always create equal-area regions.

If the height of the triangle is (6x + 10) and the base of the triangle is (3/2) the area of the triangle is 14.25 square units.

What is the area of the triangle?

The area of a triangle is the region bounded by its perimeter or its three sides.

If the height of the triangle is 'h' and the base is 'b', the area of the triangle would be

                   Area = 1/2 × height × base

The base of the triangle is x = 3/2.

Height of the triangle = 6x + 10 = 19.

Area of triangle = 1/2×3/2×19

                          = 14.25 square units.

Hence, If the height of the triangle is (6x + 10) and the base of the triangle is (3/2) the area of the triangle is 14.25 square units.

The estimated change in yy using differentials is -0.00679. This means that if xx is increased by 0.005, then yy is estimated to decrease by 0.00679. The differential of yy is dy=-5sin(5x)dxdy=−5sin⁡(5x)dx. We are given that y=cos(5x)=π/30y=cos⁡(5x)=π/30 and x=0.055x=0.055.

We want to estimate ΔyΔy, which is the change in yy when xx is increased by 0.005. We can use the differential to estimate ΔyΔy as follows:

Δy≈dy≈dy=-5sin(5x)dx

Plugging in the values of y, x, and dxdx, we get:

Δy≈-5sin(5(0.055))(0.005)≈-0.00679

• if b² - 4ac > 0 then 2 real and irrational solutions

• if b² - 4ac > 0 and a perfect square then 2 real and rational solutions

• if b² - 4ac = 0 then 2 real and equal solutions

• if b² - 4ac < 0 then no real solutions

5x² - 2x + 6 = 0 ← in standard form

with a = 5 , b = - 2 , c = 6

b² - 4ac

= (- 2)² - (4 × 5 × 6)

c  =  3.73913043

Step-by-step explanation:

Subtract  3  from -  12.2

Move all terms not containing  c  to the right side of the equation.

− 2.3 c  =  − 8.6

Divide each term in  − 2.3 c = − 8.6  by  − 2.3  and simplify.

In a triangle, the value of angle C by using Law of cosine is,

⇒ C = 32.8°

Since, A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

We have to given that;

A triangle is shown in figure.

Now, By given triangle,

Sides are,

a = 90

b = 50

c = 55

Since, WE know that;

Law of Cosines:

⇒ c² = a² + b² - 2ab cos C

Substitute all the values, we get;

⇒ 55² = 90² + 50² - 2 × 90 × 50 cos C

⇒ 3,025 = 8100 + 2500 - 9000 cos C

⇒ 9000 cos C = 10600 - 3025

⇒ 9000 cos C = 7575

⇒ cos C = 7575 / 9000

⇒ cos C = 0.84

⇒ C = 32.8°

False, in finding the t-value for a confidence interval, we cannot use the value at either the 20th or 80th percentile.

To find the t-value for a confidence interval, we need to consider the t-distribution, which is a probability distribution that is used when the sample size is small and the population standard deviation is unknown. The t-distribution is symmetric and bell-shaped, similar to the normal distribution, but it has heavier tails.

When constructing a confidence interval, we use the t-distribution to determine the critical value, which corresponds to the desired level of confidence. The critical value is based on the degrees of freedom, which is determined by the sample size. The degrees of freedom represent the number of independent observations available to estimate a parameter.

The t-distribution has a different shape for different degrees of freedom. As the degrees of freedom increase, the t-distribution approaches the shape of the standard normal distribution. The critical values for a given level of confidence are determined from the t-distribution tables or using statistical software.

The t-value corresponds to a specific percentile in the t-distribution. For example, if we have a 95% confidence level, we need to find the t-value that corresponds to the 2.5th percentile (α/2) in each tail of the distribution. This value is not located at the 20th or 80th percentile.

Using the t-value at either the 20th or 80th percentile would be incorrect and would result in an incorrect confidence interval calculation. It is essential to use the correct critical value from the t-distribution table or software based on the desired confidence level and the degrees of freedom associated with the sample size.

In conclusion, when finding the t-value for a confidence interval, we should not use the value at either the 20th or 80th percentile, but rather refer to the appropriate critical value from the t-distribution based on the desired level of confidence and the degrees of freedom.

Answer:JEROME

Step-by-step explanation:

Answer:

This equation is a difference of squares factorization. It states that the difference between the square of x and 7x plus some constant c is equal to the square of (x+a). To solve for a and c, we can expand both sides of the equation:

X^(2) - 7x + c = x^(2) + 2ax + a^(2)

And we can set them equal to each other and solve for a and c:

x^(2) - 7x + c = x^(2) + 2ax + a^(2)

-2ax - a^(2) = -7x + c

a = (7x - c) / 2x

c = x^(2) - 7x + a^(2)

Answer:

Step-by-step explanation:

The angle sum theorem helps you compute the angle inside the triangle. The inscribed angle theorem helps you compute the arc measures outside the triangle.

The Angle Sum theorem tells you the sum of angles in a triangle is 180°. That lets you write the equation ...

  X +Y +Z = 180°

  X +69° +41° = 180°

The Inscribed Angle theorem tells you an inscribed angle has half the measure of the central angle subtending the same arc. The arc and the central angle have the same measure: twice that of the inscribed angle.

  arc ZY = 2×∠X

  arc XY = 2×∠Z

Using the equations we wrote describing the relationships of the unknowns to the known information, we find ...

  X = 180° -110° = 70°

  arc ZY = 2×70° = 140°

  arc XY = 2×41° = 82°

Answer:Angle x=70°

Step-by-step explanation:interior angles add up to 180° so we add 41° and 69°. After addition,you minus from 180° and you get 70°

The relative risk of being alive at 5-years after diagnosis associated between white men and black men is 2.03.

In the US, among a representative group of 6,006 white men and 1,126 black men, ages 70-79 years at diagnosis of stage IV prostate cancer: 2,337 white men and 344 black men were alive after 5 years of follow-up.

In order to calculate the relative risk of being alive at 5-years after diagnosis associated between white men and black men, we can use the following formula:

Relative risk = [ (number of white men alive after 5 years) / (total number of white men) ] ÷ [ (number of black men alive after 5 years) / (total number of black men) ]

Therefore, substituting the values given in the formula we get;

[ (2,337) / (6,006) ] ÷ [ (344) / (1,126) ] = 0.63 ÷ 0.31 = 2.03

Therefore, the relative risk of being alive at 5-years after diagnosis associated between white men and black men is 2.03.
