Select all statements that are true for density curves.
The curve is on or above the horizontal axis.
The total area under the curve is 1
The curve is symmetric and single peaked
The proportion of data values between two numbers and is the area under the curve between a and b.
The curve satisfies the 68.95.99.7% rule.
Answer:
The curve is on or above the horizontal axis ⇒ 1st
The total area under the curve is 1 ⇒ 2nd
The proportion of data values between two numbers and is the area
under the curve between a and b ⇒ 4th
Step-by-step explanation:
* Lets explain the meaning of density curve
- Density curve is a mathematical model for a distribution of a variable
- It is another type of graph that represents a quantitative variables
- It describes the overall pattern of a distribution
- Its area is always on or above the horizontal axis
- Its area under the curve is exactly 1
- It can come in many shapes - symmetric, right-skewed, left-skewed
- The area under the curve and above any range of values on the
horizontal axis is the proportion of all observations that fall in
that range
- Ex: density curve describes the probability distribution of a
continuous random variable
The probability of any event is the area under the curve and above
the values that make up the event.
* Now lets chose the true statements
# The curve is on or above the horizontal axis
# The total area under the curve is 1
# The proportion of data values between two numbers and is the area
under the curve between a and b
While most of the provided characteristics apply to all density curves, namely their position on or above the horizontal axis, their unit area, and the proportion interpretation of the area, they are not necessarily single peaked or symmetric and do not always follow the 68-95-99.7% rule.
Explanation:The given statements about density curves are true:
The curve is on or above the horizontal axis: This indicates that the values of density (frequency per unit measure) are always non-negative. The total area under the curve is 1: This reflects the fact that the total probability of all potential outcomes (as represented by the area of the curve) is 1. The proportion of data values between two numbers a and b is the area under the curve between a and b: This is because the area under the density curve gives the probability, which interprets as the proportion in this context.
However, two of the provided statements have elements that do not apply universally:
The curve is symmetric and single peaked: This is not always the case. A density curve can be skewed or can have multiple peaks. The curve satisfies the 68-95-99.7% rule: This rule applies only to normal (bell-shaped) distributions, not all density curves.Learn more about Density Curves here:https://brainly.com/question/18345488

The question is asking to solve for 'r' in the given equation. After simplifying to 9x - 6 - r = 9x -7 and solving for 'r', we find r = 1.
Explanation:The given equation is 3(2x - 2) - r + 3x = 2(7x + 1) – 5x - 9. To solve for 'r', we first simplify both sides of the equation. Distributing on the left side, we obtain 6x - 6 - r + 3x. On the right side we have 14x + 2 - 5x - 9. After simplifying, we obtain 9x - 6 - r = 9x -7. Subtracting 9x from both sides, we have -6 - r = - 7. Finally, solving for 'r', we add 6 to both side to get r = 1

The number 44.4 is what percent of 74?
Answer:
60%
Step-by-step explanation:
[tex]percentage = \frac{44.4}{74} \times 100\% = 60\%[/tex]
Answer:
60%
Step-by-step explanation:
In questions like these, we take 74 to be the whole. As such, we express the whole as 100%. Then, we take 44.4 as just a portion of the whole. We therefore ask ourselves, what portion of the whole is 44.4.
We take 44.4 as the numerator and the whole, 74, as the denominator. We then express 44.4 as a fraction of the denominator. That is,
44.4/74
To express this as a percent, we multiply the above results by 100.
Thus, (44.4/74) x 100
= 60%

The difference of two numbers is 2 the product of the two numbers is 440 what are the two numbers explain
Final answer:
To solve the student's question, we created a system of equations based on the given conditions, solved for the two numbers using algebraic methods, and verified that the numbers 22 and 20 have a difference of 2 and a product of 440.
Explanation:
The student has asked to find two numbers where their difference is 2 and their product is 440. This problem can be solved by establishing a system of equations and using algebraic methods to find the two numbers.
Let x be the larger number and y be the smaller number. According to the question, we have two equations:
x - y = 2
x × y = 440
From the first equation, y can be expressed as x - 2. Subsequently, by substituting y in the second equation, we get x(x - 2) = 440. Simplifying this yields a quadratic equation: x² - 2x - 440 = 0. Solving the quadratic equation gives us two possible values for x, which we can then use to find the corresponding values of y.
By factoring, we determine the two numbers that satisfy both conditions are 22 and 20. To verify this, we must ensure that the difference between these two numbers is 2 and their product is 440, which is indeed the case: 22 - 20 = 2 and 22 × 20 = 440.
Given that DJ║KE, ∠DBF = 37°, and ∠angle ABC = 46°, find the measure of ∠GCE in degrees.
Check the picture below.
Final answer:
To find the measure of ∠GCE, apply the properties of parallel lines and angles in triangles, leading to a solution of 83°.
Explanation:
Given that DJ║KE, ∠DBF = 37°, and ∠ABC = 46°, we can determine the measure of ∠GCE as follows:
Since DJ║KE, we have alternate interior angles, meaning ∠GCE = ∠DBF = 37°.
Now, ∠ACB is the exterior angle to the triangle ∆FCE, and by the Exterior Angle Theorem, ∠GCE + ∠ACB = ∠FCE = 180°.
Substitute the known values to find ∠GCE: 37° + 46° = 83°. Therefore, ∠GCE is 83°.
solve 3x^2=-12-6x by completing the square
Answer:
x = - 1 ± i [tex]\sqrt{3}[/tex]
Step-by-step explanation:
Given
3x² = - 12 - 6x ( add 6x to both sides )
3x² + 6x = - 12 ( divide through by 3 )
x² + 2x = - 4
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(1)x + 1 = - 4 + 1
(x + 1)² = - 3 ( take the square root of both sides )
x + 1 = ± [tex]\sqrt{-3}[/tex] = ± i [tex]\sqrt{3}[/tex] ( subtract 1 from both sides )
x = - 1 ± i [tex]\sqrt{3}[/tex]

7 1/2 of what number is 12
To find what number 7 and 1/2 of is equal to 12, we can set up an equation and solve for the unknown number.
Explanation:To find out what number 7 and 1/2 of is equal to 12, we can set up an equation.
We can represent the unknown number as x.
So, the equation becomes: 7 and 1/2 * x = 12
Next, we need to convert the mixed number 7 and 1/2 to an improper fraction. 7 and 1/2 is equal to 15/2. So the equation now becomes: (15/2) * x = 12
To solve for x, we can multiply both sides of the equation by the reciprocal of 15/2, which is 2/15.
This cancels out the fractions on the left side of the equation, giving us: x = (12 * 2)/15
By multiplying 12 and 2, we get 24. And by dividing 24 by 15, we get the final answer: x = 24/15, which can be simplified to x = 8/5 or x = 1.6.

lisa has played in 6 soccer matches. Her brother josh has played in 18 soccer matches. lisa saay josh has played in 12 times as many matches as she has. Use the drop-down menus to explain why lisa statement is not correct.
Lisa's assertion that Josh has played twelve times as many soccer matches as her is false. In actuality, Josh has played three times as many matches as Lisa.
Explanation:In the scenario, Lisa claims that her brother Josh has played in 12 times as many soccer matches as she has. To verify this statement, we would have to multipy the number of matches Lisa played by 12. Hence, 6 (Lisa's matches) times 12 equals to 72 matches. However, we know from the question that Josh has only played 18 matches. Therefore, Lisa's statement is incorrect because, in reality, Josh has only played three times as many matches as Lisa (18 divided by 6 equals 3), not 12 times as many.

Lisa's statement is not correct because Josh has played in 3 times as many soccer matches as Lisa.
Explanation:
Lisa's statement is not correct because she says Josh has played in 12 times as many matches as she has, but this is not the case. To determine how many times more matches Josh has played compared to Lisa, we can calculate the ratio of Josh's matches to Lisa's matches.
Josh has played in 18 soccer matches and Lisa has played in 6 soccer matches. To find out how many times more matches Josh has played, we divide Josh's matches by Lisa's matches:
Josh's matches / Lisa's matches = 18 / 6 = 3
So, Josh has played in 3 times as many soccer matches as Lisa. Lisa's correct statement would be that Josh has played in 3 times as many matches as she has.

What Is 5/6 + (-1 1/6)?
The sum of 5/6 and -1 1/6, when understood as fractions, results in the simplified answer of -1/3.
Explanation:To calculate the sum of 5/6 and (-1 1/6), we must first understand the concept of fractions and negative numbers.
5/6 is simply a fraction. The number -1 1/6, however, is a negative mixed number, which consists of an integer (-1) and a fraction (1/6).
We convert this negative mixed number to a simple fraction to make the calculation easier. -1 1/6 becomes -6/6 - 1/6 which equals -7/6.
Now we add the two fractions: 5/6 and -7/6. These two fractions have the same denominator, so we simply add the numerators: 5 + (-7) = -2.
Therefore, 5/6 + (-1 1/6) is equal to -2/6, which simplifies to -1/3.
