Question Given that sin(0) = 2√13 13, and is in Quadrant IV, what is cos(20)? Provide your answer below:

The newborn death rate is calculated by dividing the number of newborn deaths by the number of live births and multiplying by 100.

The newborn death rate, also known as the neonatal mortality rate, is a critical indicator used in public health to assess the health and well-being of newborns. It is calculated by dividing the number of newborn deaths within a specified period by the number of live births during the same period and then multiplying the result by 100.

This calculation is performed to express the newborn death rate as a percentage, making it easier to interpret and compare across different populations or time periods. By dividing the number of deaths by the number of live births, we obtain the proportion of newborns who die within a certain timeframe. Multiplying this proportion by 100 provides the rate per 100 live births, which allows for a standardized measure of comparison.

The newborn death rate is a crucial statistic in assessing the quality of healthcare services, identifying areas with high mortality rates, and monitoring the effectiveness of interventions aimed at reducing neonatal deaths. It serves as a vital tool for policymakers, healthcare professionals, and researchers in evaluating and improving newborn health outcomes.

Answer:

Well on of the properties states that unless there are parenthesis, you multiply and divide first then you add and subtract. So, first we multiply 28*4 and that leaves use with 112, now if there is no more multiplication, division, or parentheses, and there's not. We can continue all we do is add 18+112 and we get our answer of 130.

Answer: Use the distributive property and expand 28, then distribute the 4 to 20 and the 4 to 8. Then you have 18 + 80 + 32. Use commutative property to reverse the order of 32 and 80 so that 18 and 32 are friendly numbers to add.

After solving the given inequality question, we will get  x < -9.

A mathematical sign for comparing two values or expressions is an inequality symbol. Inequality symbols include: (less than), > (greater than), (less than or equal to), and (greater than or equal to). Inequalities can be used to represent connections between two or more variables, for as 5 10 indicating that 5 is less than 10. Inequalities can also be used to define mathematical equations or to describe connections between variables. The equation x + 2 7 can, for example, be used to represent the relationship between x and 7, or to communicate that the value of x must be less than 5 for the equation to be true.

In the given question,

2/3x + 2y < -1/3x + 1

⇒ 2/3x + 2y - (-1/3x + 1) < 0

⇒ 5/3x + 3 < 0

⇒ 5/3x < -3

⇒ x < -9

The second linear equation will be linearly dependent to the first equation. The graphs of the two linear equation will be parallel to each other.

When two systems of linear equation is given and they do not have a solution that means the  first one is depended on the second one or the second equation is depended on the first set of equations.

The system of linear equations that does not posses a solution is called inconsistent form of linear equation where the multiples of the variables are multiples of each other but the constant is completely different.

The samples of size n = 2 that can be drawn from this population is calculated as

Sample = N!/(n! * (N - n)!)

Therefore, the resulting error in the volume of the sphere is approximately 1.13 cubic inches.

To estimate the resulting error in the volume of the sphere, we can use linear approximation. The formula for the volume of a sphere is given by:

V = (4/3)πr³

where V is the volume and r is the radius.

The linear approximation formula is given by:

ΔV ≈ dV/dr × Δr

where ΔV is the resulting error in the volume, dV/dr is the derivative of the volume with respect to the radius, and Δr is the error in the radius.

Taking the derivative of the volume formula with respect to the radius, we have:

dV/dr = 4πr²

Given that the radius is claimed to be 3.0 inches, correct to within 0.01 inch, we can consider the error (Δr) to be 0.01 inch.

Now we can substitute the values into the linear approximation formula:

ΔV ≈ dV/dr × Δr

ΔV ≈ (4π(3.0)²) × 0.01

ΔV ≈ (4π(9.0)) × 0.01

ΔV ≈ (36π) × 0.01

ΔV ≈ 0.36π

Approximating π to be 3.14, we can calculate the resulting error:

ΔV ≈ 0.36π

ΔV ≈ 0.36 × 3.14

ΔV ≈ 1.13 cubic inches

Therefore, the resulting error in the volume of the sphere is approximately 1.13 cubic inches.

When rotating a point 270 degrees counterclockwise about the origin our point A(x,y) becomes A'(y,-x). This means, we switch x and y and make x negative.

Step-by-step explanation:

This is a contradiction, which means that our initial assumption that there are n children is incorrect. Therefore, there is no solution to this problem that satisfies the given conditions.

Let's assume that there are n children in the Smith family.

We know that the father is 48 years old, so the sum of the ages of the mother and children is:

Total age = (n + 1) * 20 (as there are n children and 1 father)

And we also know that the average age of the mother and children is 16, so we can write:

Total age / (n + 1) = 16

Combining these two equations, we get:

(n + 1) * 20 / (n + 1) = 16

Simplifying, we get:

20 = 16

Now we proceed to present the graphs of the polygon and its image with the help of a graphing tool. The original polygon is highlighted in red and the image is highlighted in blue.

DIlations are defined by the follwing operation:

\(P'(x,y) = O(x,y) + k\cdot [P(x,y)-O(x,y)]\) (1)

Where:

If we know that \(O(x,y) = (1,1)\), \(k = 0.5\), \(J(x,y) = (3,1)\), \(K(x,y) = (5, -3)\), \(L(x,y) = (5,5)\) and \(M(x,y) = (3,7)\), then the coordinates of the new polygon are:

\(J'(x,y) = (1,1) + 0.5\cdot [(3,1)-(1,1)]\)

\(J'(x,y) = (1,1)+0.5\cdot (2,0)\)

\(J'(x,y) = (1,1) +(1,0)\)

\(J'(x,y) = (2,1)\)

\(K'(x,y) = (1,1) + 0.5\cdot [(5,-3)-(1,1)]\)

\(K'(x,y) = (1,1) +0.5\cdot (4,-4)\)

\(K'(x,y) = (1,1) +(2,-2)\)

\(K'(x,y) = (3,-1)\)

\(L'(x,y) = (1,1) + 0.5\cdot [(5,5)-(1,1)]\)

\(L'(x,y) = (1,1) + 0.5\cdot (4,4)\)

\(L'(x,y) = (1,1) + (2,2)\)

\(L'(x,y) = (3,3)\)

\(M'(x,y) = (1,1) + 0.5\cdot [(3,7)-(1,1)]\)

\(M'(x,y) = (1,1) +0.5\cdot (2,6)\)

\(M'(x,y) = (1,1) +(1,3)\)

\(M'(x,y) = (2,4)\)

Now we proceed to present the graphs of the polygon and its image with the help of a graphing tool. The original polygon is highlighted in red and the image is highlighted in blue.

Answer:

The answer is √26

Step-by-step explanation:

Let the point be A and B i.e.,

A = (11, 7)

B = (16, 6)

Now, The distance between A and B

AB = √(x₂ – x₁)² + (y₂ – y₁)²

AB = √(16 – 11)² + (6 – 7)²

AB = √(5)² + (-1)²

AB = √25 + 1

AB = √26

The expression is written with parentheses and the signs will be 5 + 23 + 18 x (8 - 4) = 100.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

5 + 23 + 18 x (8 - 4) = 100

Simplify the expression, then we have

5 + 23 + 18 x (8 - 4) = 100

43.36% of the scores fall between 690 and 900 on the collegiate mathematics readiness assessment.

To determine the percentage of scores between 690 and 900, we need to calculate the area under the normal distribution curve between these two values.

First, we need to standardize the scores using the formula z = (x - μ) / σ, where x is the score, μ is the mean, and σ is the standard deviation.

For the score 690:

z1 = (690 - 680) / 120 = 0.0833

For the score 900:

z2 = (900 - 680) / 120 = 1.8333

Next, we need to find the area between these two standardized scores. We can use a standard normal distribution table or a statistical calculator to find the corresponding probabilities.

From the standard normal distribution table, we find that the area to the left of z1 is approximately 0.5328 and the area to the left of z2 is approximately 0.9664.

To find the area between z1 and z2, we subtract the smaller area from the larger area:

Area = 0.9664 - 0.5328 = 0.4336

Finally, we convert the area to a percentage by multiplying by 100:

Percentage = 0.4336 * 100 ≈ 43.36%

Therefore, approximately 43% of the scores fall between 690 and 900 on the collegiate mathematics readiness assessment.
