if heart disease death rate were expressed as deaths per 1,000 people instead of as deaths per 100,000 people, how would the correlation r between wine consumption and heart disease death rate change?

Rounded to the nearest whole number, the probability that the two cards dealt to Annika will both be diamonds is 9.52%. The concept that is used to answer this question is probability.

To calculate the probability that Annika gets two diamond cards dealt to her, we need to find the number of favorable outcomes (getting two diamond cards) and divide it by the total number of possible outcomes (getting any two cards from the remaining 15 cards in the deck).

Since the cards are dealt without replacement, the total number of possible outcomes will be (15 choose 2) = 105.

To find the number of favorable outcomes, we need to find the number of ways to choose 2 cards from the 5 remaining diamond cards. This can be calculated as (5 choose 2) = 10.

So the probability of getting two diamond cards dealt to Annika is: (Number of favorable outcomes) / (Total number of possible outcomes) = 10/105

To express the probability in percentage format, we multiply the fraction by 100

10/105 * 100 = 9.52%

The correct answer is B. $1,000. According to a survey conducted by Bankrate in 2019, 48% of Americans reported having less than $1,000 in savings.

This can be calculated using the following formula:

Percentage of Americans with less than $1,000 in savings = (Number of Americans with less than $1,000 in savings / Total number of Americans surveyed) x 100

Using the data from the survey, the formula can be expressed as follows:

Percentage of Americans with less than $1,000 in savings = (11,094 / 23,064) x 100 = 48.1%

This means that nearly half of all Americans reported having less than $1,000 in savings. This is a concerning statistic, as it indicates that many Americans are not preparing adequately for financial emergencies.

The distance between the point A and B is 15 units.

The distance between two points can be found using Pythagoras's principle.

Point A is located at (7,4), and point B is located at (-8,4). Let's find the distance between point A and B as follows:

Therefore,

d = √(y₂ - y₁)² + (x₂ - x₁)²

Hence, using (7, 4) (-8, 4)

x₁ = 7

x₂ = -8

y₁ = 4

After solving the linear system of equations given, the result shows it has infinitely many solutions.

In mathematics, a collection of two or more linear equations containing the same variables is referred to as a system of linear equations. Here, one might say that linear equations are those of the first order, where the maximum power of the variable is 1. One variable, two variables, or three variables can all be included in a linear equation.

Systems of equations known as linear systems are those in which the variables are always multiplied solely by constants before being added together. Both static and dynamic relationships between variables are described by linear systems.

105 joule/second is the power generated in a body moving at a velocity of 15m/s with a force of 7N in 2s​

The word "force" has a specific meaning in science. At this level, calling a force a push or a pull is entirely appropriate. A force is not something an object "has in it" or that it "contains." One thing experiences a force from another. There is no distinction between living and non-living things in the concept of a force.

Given, a body moving at a velocity of 15m/s with a force of 7N in 2s​

From the general formula of Power

Power = force * velocity

In our case

force = 7N

velocity = 15 m/s

Thus,

Power = 7 * 15 Nm/s

Power generated in body = 105 Nm/s or joule/s

Therefore, the power generated in a body moving at a velocity of 15m/s with a force of 7N in 2s​ is 105 joule/second.

Answer:

Attached, [tex]p \geq 4[/tex]

To solve, you must isolate the variable. It means moving the variable and it's coefficient to the other side of the equation by itself.

If you multiply, divide, add, subtract, square root, exponent both sides of the equation by the same value, that end value stays the same. That is how you solve for it.

However, if you divide or multiply by a negative number by both sides in an inequality, you must flip the sign.

For example:

> to <

to

Divide -4 on both sides.

[tex]\frac{-16}{-4} \geq \frac{-4p}{-4}[/tex]

[tex]4 \geq p[/tex]

Flip the sign.

[tex]4\leq p[/tex]

[tex]p\geq 4[/tex]

When the line is pointing right, it means the variable is greater than the said number. If the dot is filled in, it means greater than or equal to or less than or equal to. If it is not filled in, it means greater than or less then.

The answer is:

4 ≤ p

Work/explanation:

The inequality is:

[tex]\sf{-16\geqslant-4p}[/tex]

To solve, divide each side by -4. Since we're dividing by a negative number, we will reverse the inequality sign.

The formula of v is equal to the ratio of 10u to (u+10) that is 10u/(u+10).

The given formula is an equation that relates two variables, u and v, in an experiment on lenses. The equation states that the ratio of (u - v) to (uv) is equal to 1/10.

That is,

u-v / uv = 1/10

To solve for v, we can use algebraic manipulation techniques. By multiplying both sides of the equation by (uv), we get

(u - v) = (uv) / 10.

Then, by adding v to both sides, we get,

u = v + (uv) / 10

u = v (1 + u/10)

10u = v (u+10)

Finally, by dividing both sides by (u+10), we arrive at the final solution:

v = (10u/(u+10))

Aaron's weight is $118$ pounds - $54$ pounds = $64$ pounds more than Levi's weight.

Weight is a measure of the gravitational force of attraction between an object and the Earth, or between two objects. It is measured in Newtons (N) or kilograms (kg). Weight is created by the force of gravity that pulls objects toward the center of the Earth. The greater the mass of an object, the greater the force of gravity and thus the greater its weight. Weight is an important factor in determining the motion of an object and its interaction with other objects.

Aaron's weight is $10$ pounds more than twice Levi's weight, so Levi's weight is $\frac{1}{2}(118 - 10) = 54$ pounds. This means that Aaron's weight is $118$ pounds - $54$ pounds = $64$ pounds more than Levi's weight.
