Answer:
0.121
Step-by-step explanation:
From the given information:
Let X be a hypergeometric random variable. i.e X \(\sim\) h (x;:6,7,12)
To determine the mean and the standard deviation of X of a hypergeometric random variable; we have:
\(\mu_x = E(X)\)
\(\mu_x = 6 \times \dfrac{7}{12}\)
\(\mu_x =1 \times \dfrac{7}{2}\)
\(\mu_x =3.5\)
The standard deviation is :
\(\sigma _x = \sqrt{(\dfrac{12-6}{12-1}) \times 6 \times (\dfrac{7}{12})\times (1-\dfrac{7}{12})}\)
\(\sigma _x = \sqrt{(\dfrac{6}{11}) \times 6 \times (\dfrac{7}{12})\times (\dfrac{5}{12})}\)
\(\sigma _x = \sqrt{\dfrac{35}{44}}\)
\(\sigma _x = 0.892\)
However, the inequality for the event showcasing how X exceeds its mean value by more than 1 standard deviation is :
\(X \geq \mu_x +\sigma_x\)
\(X \geq 3.5 +0.892\)
\(X \geq 4.392\)
\(X \geq 5\)
∴
\(P(X \geq \mu_x + \sigma_x ) = P(X \geq 5)\)
\(P(X \geq \mu_x + \sigma_x ) = 0.121\)
for time, , in hours, , a bug is crawling at a velocity, , in meters/hour given by use to estimate the distance that the bug crawls during this hour. use left- and right-hand riemann sums to find an overestimate and an underestimate. then average the two to get a new estimate.
The distance, which is determined by integrating the velocity function over the specified time interval, is calculated as 2.98 and 2.58.
We will use left Riemann sum and right Riemann sum to obtain an overestimate and an underestimate. The definite integral, which in this case is a distance, can also be approximated using the average of these estimates.
1 ) The distance the bug crawls obtained by integrating the velocity function v(t) = 4/1+t over the inclined time interval is
\(\int\limits^1_0 \, \frac{4}{1+t} dt.\)
Splitting the interval [0, 1] into sub intervals of length Δt = 0.2, we get the Riemann sum L and the right Riemann sum R:
L = ∑⁴ v(ti) Δt
L = (0.2) (v(0) + v(0.2) + v(0.4) + v(0.6) + v(0.8))
L ≈ 2.98
R = ∑⁵ v(ti) Δt
R = (0.2) (v(0.2) + v(0.4) + v(0.6) + v(0.8) + v(1.0))
R ≈ 2.58
2 )The average of these two Riemann sums gives us a new estimate for the distance :
AVG = (2.98 + 2.58)/2
=2.78.

si la medida de un angulo es tres veces la medida de su suplemento cual es la medida del angulo
Answer:
El ángulo lo representaremos por A
Su suplemento es 180-A
A=3(180-A)
A=540-3A
3A+A=540
4A=540
A=540/4
A=135°
Step-by-step explanation:
135=3(180-135)
135=3(45)
135=135
The measure of the angle is 135 degrees when the measure of an angle is three times the measure of its supplement.
Let's denote the measure of the angle as x.
The supplement of an angle is the angle that, when added to the given angle, equals 180 degrees. So, the measure of the supplement of the angle is 180 - x.
According to the given information, the measure of the angle is three times the measure of its supplement. Mathematically, we can express this as:
x = 3( 180 - x )
Now, let's solve this equation to find the measure of the angle:
x = 3( 180 - x )
x = 540 - 3x
4x = 540
x = 540 / 4
x = 135
Therefore, the measure of the angle is 135 degrees.

Which congruence theorem can be used to prove △WXZ ≅ △YZX? Triangles W X Z and Y Z X share side X Z. Angles W X Z and X Z Y are right angles. Angles X W Z and X Y Z are congruent. AAS ASA SAS HL
Answer:
The correct option is AAS.
Step-by-step explanation:
Consider the diagram below.
It is provided that The triangles △ WXZ and △ YZX share a side XZ.Angles ∠WXZ and ∠XZY are right angles.Angles ∠XWZ and ∠XYZ are congruent.If two angles are congruent it implies that they are same in degrees or radians.
So, the angles ∠XWZ and ∠XYZ are equal.
So, in the diagram below, one of the triangles have two angles that are equal to the corresponding angles on the other triangle and the two triangles share a side.
Then according to the Angle-Angle-Side (AAS) statement the triangles △ WXZ and △ YZX are congruent.
Thus, the correct option is AAS.
The congruence theorem that can be used to prove that △WXZ ≅ △YZX is; AAS
We are told that;ΔWXZ and ΔYZX share side XZ
∠WXZ and ∠XZY are right angles
∠XWZ and ∠XYZ are congruent
Now, from the given parameters, we can say that from reflexive property of congruence, XZ is congruent to itself and thus, we have one side of both triangles that is congruent.Secondly, since ∠WXZ and ∠XZY are right angles, it means they are equal and therefore congruent to each other.Lastly, we are told that ∠XWZ and ∠XYZ are congruent.In summary, we have 2 corresponding angles and one corresponding side that are equal but the corresponding side is not with the included angles and as such the triangles are congruent by AAS Congruency.Read more about AAS Congruency at; https://brainly.com/question/7727792

Suppose you draw one card, put it back (and re-shuffle), and then draw another. What is the probability that the cards are of different suits
The probability that the two cards drawn are of different suits is approximately 0.3744 or 37.44%.
The probability that the first card drawn is of a particular suit (say hearts) is 13/52, because there are 13 hearts in the deck. The probability that the second card drawn is of a different suit (say diamonds) is 39/52, because there are 13 cards in each of the three remaining suits.
So, the probability that the first card is a heart and the second card is a diamond is (13/52) × (39/52) = 507/2704.
Similarly, the probability that the first card is a diamond and the second card is a heart is also (13/52) × (39/52) = 507/2704.
The probability that the two cards are of different suits is the sum of these two probabilities:
(507/2704) + (507/2704) = 1014/2704 ≈ 0.3744

what are some issues you must consider when choosing the appropriate number of treatment conditions for your experiment? what does it mean to have conditions that are proportional to each other?
When selecting the appropriate number of treatment conditions, it is essential to consider factors such as resources, research complexity, and confounding variables.
Having conditions that are proportional to each other means that the level or intensity of each condition varies in direct proportion to the others, such that if one condition is increased or decreased, the others are also adjusted in a corresponding manner.
When choosing the appropriate number of treatment conditions for an experiment, there are several issues to consider. One of these is the ability to distinguish differences between treatment conditions.
A suitable number of treatment conditions for an experiment should be able to identify important differences between them. If there are too few treatment conditions, differences may not be identified, while if there are too many treatment conditions, resources may be wasted, making it difficult to obtain meaningful results.Another factor to consider is the need for replicability. The more treatment conditions that are used, the more difficult it is to replicate the experiment. A suitable number of treatment conditions should allow for replicability, meaning that the experiment can be repeated with similar results.To have proportional treatment conditions means that the levels of the independent variable (the treatment) are proportionate. This means that the differences between the levels of the independent variable are proportional to each other. This is important because it ensures that the treatment conditions are balanced and that the results obtained are valid. If the levels of the independent variable are not proportional, it can be difficult to interpret the results and draw conclusions.Having conditions that are proportional to each other means that the differences between treatment conditions are consistent across all levels of the independent variable. In other words, if the independent variable increases by a certain amount, the difference between the treatment conditions remains constant. This can be important for ensuring that the treatment effects are interpretable and generalizable to other populations.

A bouncy ball is dropped such that the height of its first bounce is 6 feet and each successive bounce is 60% of the previous bounce's height. What would be the height of the 7th bounce of the ball? Round to the nearest tenth (if necessary).
sorry for the mess
Answer:
The height of the 7th bounce of the ball is approximately 0.28 feet, rounded to the nearest tenth would be 0.3 feet.
Step-by-step explanation:
To find the height of the 7th bounce of the ball, we need to calculate the height of each bounce starting from the first. We know that the first bounce has a height of 6 feet. Each subsequent bounce will be 60% of the previous bounce's height. So we can use the following formula:
height of nth bounce = 0.6^(n-1) * 6
where n is the number of the bounce we want to find the height of.
For the 7th bounce, we have:
height of 7th bounce = 0.6^(7-1) * 6
height of 7th bounce = 0.6^6 * 6
height of 7th bounce = 0.046656 * 6
height of 7th bounce ≈ 0.28 feet
So the height of the 7th bounce of the ball is approximately 0.28 feet, rounded to the nearest tenth would be 0.3 feet.
Answer: 0.279936 ft or 0.3 ft rounded
Step-by-step explanation: Use an exponential function to model this equation. In this case use \(6(0.6)^(x-1)\) where x represents the number of bounces. The -1 is there because it starts at 6 feet after the first bounce. Plug in 7 for x and the result is above.

State the assumption you would make to start an indirect proof of each statement.
PQ ⊕ ST
To start an indirect proof of the statement PQ ⊕ ST, the assumption would be that PQ and ST are both true.
An indirect proof, also known as proof by contradiction, begins by assuming the opposite of what we want to prove and showing that it leads to a contradiction. In the case of the statement PQ ⊕ ST (which represents the exclusive disjunction or XOR between PQ and ST), we want to prove that either PQ or ST is true, but not both.
To begin the indirect proof, we assume that both PQ and ST are true. This assumption implies that either PQ is true and ST is false, or PQ is false and ST is true. However, since PQ and ST are mutually exclusive in an XOR statement, it follows that both PQ and ST cannot be simultaneously true. This creates a contradiction with our assumption, as we assumed both PQ and ST to be true.
By reaching a contradiction, we can conclude that our assumption is incorrect. Therefore, we can deduce that either PQ or ST is true, but not both. This indirect proof establishes the validity of the statement PQ ⊕ ST.
