Yes, the P-value is the probability, assuming H0 is true, of observing a value for the test statistic that is as extreme as or more extreme than the value actually observed.

The p-value is the probability of obtaining a statistic that is more or more extreme than that observed in experiment.

The p-value is calculated assuming the null hypothesis is true. Therefore, the lower the p-value, the stronger the evidence that the null hypothesis is false. That is, the lower the p-value, the stronger the evidence in favor of the alternative hypothesis.

The P-value is the observed test statistic (i.e., the data summary) that is as extreme as or more extreme than the currently observed test statistic under a statistical model that specifically assumes that the hypothesis is being tested. is the probability that It's true.

The simplified expression for representing the area of the circle that has radius (4x + 3) is π(16x² + 24x + 9)

The area of the circle with radius 'r' can be represented by the formula,

Area = πr²

where 'r' is the radius of the circle, π (pi) is a mathematical constant which is approximately equals to 3.14, so to find the area of the circle we must know the radius of the circle.

So Area for a circle with radius (4x + 3), the area can be represented as

= π(4x + 3)²

= π(16x² + 24x + 9)

 A representitive sample can be attained if he looks at the age and gender of the people going to the movies.

Step-by-step explanation:

Ka and Kb are both acid-base equilibrium constants, but they apply to different types of reactions. Ka (acid dissociation constant) is used to describe the dissociation of an acid in water, while Kb (base dissociation constant) is used to describe the dissociation of a base in water.

Specifically, Ka is a measure of the strength of an acid in terms of how easily it donates a proton (H+) to a solvent like water. A higher Ka value indicates a stronger acid, while a lower Ka value indicates a weaker acid. Kb, on the other hand, is a measure of the strength of a base in terms of how easily it accepts a proton (H+) from a solvent like water. A higher Kb value indicates a stronger base, while a lower Kb value indicates a weaker base. There is a mathematical relationship between Ka and Kb for conjugate acid-base pairs, which are molecules or ions that differ by the presence or absence of a single proton. The relationship is expressed by the equation: Ka x Kb = Kw, where Kw is the ion product constant for water, which is 1.0 x 10⁻¹⁴ at 25°C. This relationship shows that the stronger the acid, the weaker its conjugate base, and vice versa.

Answer:

A 0.4kg object rolling at 2 m/s that's d right answer

Answer:

A 0.4 kg object moving at 4 m.

Step-by-step explanation:

The heavier the object is, the faster it goes. Also the faster is goes and the heavier it is, the more momentum it has.

The values of E(X) = 3.25 and Var(X) ≈ 2.238 for the number of spades in a hand of 13 cards chosen at random from a 52-card deck.

To find E(X) and Var(X) for the number of spades in a hand of 13 cards chosen at random from a 52-card deck, we will use the concepts of probability and statistics.

E(X), or the expected value, is the average number of spades you would expect to get in a hand of 13 cards. To find E(X), we can use the formula:

E(X) = (Number of spades in the deck / Total number of cards in the deck) * Number of cards drawn

E(X) = (13 spades / 52 cards) * 13 cards drawn
E(X) = (1/4) * 13
E(X) = 3.25

So, the expected number of spades in a 13-card hand is 3.25.

Next, let's find Var(X), or the variance, which is a measure of how much the number of spades can vary from the expected value. We can use the formula for variance of a hypergeometric distribution:

Var(X) = (Number of cards drawn * Number of spades * Number of non-spades) / ((Total number of cards in the deck)^2 * (Total number of cards in the deck - 1))

Var(X) = (13 cards drawn * 13 spades * 39 non-spades) / ((52 cards)^2 * (52 cards - 1))
Var(X) = (13 * 13 * 39) / (52 * 52 * 51)
Var(X) ≈ 2.238

So, the variance for the number of spades in a 13-card hand is approximately 2.238.

In summary, E(X) = 3.25 and Var(X) ≈ 2.238 for the number of spades in a hand of 13 cards chosen at random from a 52-card deck.

Answer:

389

Step-by-step explanation:

20 - 11 = 9

29 - 20 = 9

This is a geometric sequence with a common difference of 9.

a_1 = 11

a_2 = 11 + 9

a_3 = 11 + 2 × 9

...

a_n = 11 + (n - 1) × 9

a_43 = 11 + (43 - 1) × 9

a_43 = 11 + 42 × 9

a_43 = 389

Hence, the \(43\)rd term is \(389\).

What is the sequence?

A  sequence is a list of objects, typically numbers, in which order matters, repetition is allowed, and the same elements can appear multiple times at different positions in the sequence.

Here given sequence is \(11, 20, 29, ...\)

Here,

\(a=11\\\\d=a_2-a_1\\d=20-11\\d=9\)

The general formula is

\(a_n=a+(n-1)d\)

where,

\(a_n\) is the \(n\)th term

\(a\) is the first term

\(n\) is the number of terms

\(d\) is the common difference

Substituting the values in the general formula

\(a_n=a+(n-1)d\\\\a_{43}=11+(43-1)9\\\\a_{43}=11+(42)9\\\\a_{43}=11+378\\\\a_{43}=389\)

Hence, the \(43\)rd term is \(389\).

Answer: Cold length 7+days and medicine taken is 0.24, the box under is 0.76. Cold length 7+days and medicine not taken is 0.69 and the box under is 0.31. It should look like: 0.24 0.69

0.76. 0.31

Step-by-step explanation: the box is vertical, the total is on the bottom and not the side. This means that you would have to add 6 and 19 together to get 25. 6/25 is 0.24 and the box under would be the rest of the number to get to 1.00 (0.76) because the total is on the bottom. If the total was on the side then you would do 6+27=33, then 6/33 = 0.18 and the remaining amount needed to get to 1.00 is 0.82. Furthermore, if the table has the total at the bottom then, the numbers you add are on the bottom and top box. If the table has the total on the side then, the numbers you add are the boxes that are on the left and right. Remember to round to the nearest hundredth. Your welcome.

The two-way column relative frequency table is,

cold length (< 7 days)                10.76                               0.31                

           Total                                1.00                                 1.00                        

"It is a way to display relative frequencies (percentages or ratios), instead of just frequency counts."

For given example,

we have been given a two-way frequency table on whether medicine was taken and cold length.

We need to find the column relative frequency table.

First we find the total of each column.

                                        Medicine taken      Medicine not taken  

cold length (≥ 7 days)                6                                  27                

cold length (< 7 days)                19                                 12                

           Total                               25                                39                  

Now, divide each element of column by its respective total.

                                         Medicine taken           Medicine not taken  

cold length (≥ 7 days)                 6/25                                  27/39                

cold length (< 7 days)                19/25                                 12/39                

           Total                               25/25                                39/39

Therefore, the two-way column relative frequency table would be,

                                           Medicine taken        Medicine not taken  

cold length (≥ 7 days)                 0.24                                0.69                

cold length (< 7 days)                10.76                               0.31

The speed of the second runner is x = 40/9 miles per hour. The speed of the first runner is (4/5)x = (4/5)*(40/9) = 16/9 miles per hour.

Let the second runner's speed be x. Then the first runner's speed is 4/5 * x = (4/5)x.Therefore, the speed of the first runner is (4/5)x and the speed of the second runner is x.After running for 30 minutes, the first runner would have covered a distance of (4/5)x * 1/2 = (2/5)x miles.

The second runner would have covered a distance of x * 1/2 = (1/2)x miles. Since the runners are 2 miles apart, we can write an equation:(2/5)x + (1/2)x = 2. Multiplying both sides of the equation by 10 to eliminate fractions, we get: 4x + 5x = 40.

Simplifying the equation, we get: 9x = 40. Dividing both sides of the equation by 9, we get: x = 40/9. Therefore, the speed of the second runner is x = 40/9 miles per hour. The speed of the first runner is (4/5)x = (4/5)*(40/9) = 16/9 miles per hour.
