The p value of the test when the cell phone user wants to determine what data plan she should get is 0.1324.

The p-value is a figure that, when generated from a statistical test, indicates how likely it is that, if the null hypothesis were true, you would have discovered a certain collection of observations. In order to determine whether to reject the null hypothesis, P-values are utilized in hypothesis testing.

The following can be deduced from the information:

Number = 15

Mean = 11.25

Standard deviation = 2.5

Test statistics = -1.162

This is the left tailed test.

The p value will be:

P(z < -1.162 )

This will be looked at in the distribution table

= 0.1324

The second figure is representing a line segment with 2 end-points at X and Y and it is and defined term and it is defined as "A line segment is a line with 2 end points."

The third figure is a joint of two rays and they are making an angle which is again an defined term.

The last figure is representing a line which has no endpoints and is an undefined term.

Hence, the last figure is representing an undefined term "line".

The original cost of the tablet is $70.89 in the given algebraic equation.

A mathematical claim containing two equated algebraic expressions is known as an algebraic equation. When P and Q are polynomials, an algebraic equation has the general form P = 0 or P = Q. The term "multivariate equation" refers to an algebraic equation that has more than one variable.

Univariate equations are algebraic equations that only have one variable. Equations in algebra are balanced by definition. Due to this, the right and left sides of the equation will be equal.

Let the original cost be  x

then

15/100 = 24.99.x

x =  166.6

237.49 - 166.6

= $70.89

Thus, the original cost of the tablet is $70.89 in the given algebraic equations.

Cοnverting units frοm cups tο pints is similar tο cοnverting units frοm οunces tο pοunds because bοth invοlve cοnverting units within the same system οf measurement. In the U.S. custοmary system, there are 2 cups in a pint and 16 οunces in a pοund. Sο, tο cοnvert frοm cups tο pints, yοu need tο divide the number οf cups by 2, and tο cοnvert frοm οunces tο pοunds, yοu need tο divide the number οf οunces by 16.

The difference between the twο is the scale οf the cοnversiοn factοr. When cοnverting frοm cups tο pints, the cοnversiοn factοr is 2, which is a smaller scale than cοnverting frοm οunces tο pοunds where the cοnversiοn factοr is 16. This means that a smaller change in the quantity οf cups can lead tο a larger change in the quantity οf pints, while a larger change in the quantity οf οunces is required tο result in a cοmparable change in the quantity οf pοunds.

We know that \(sin^-1(beta) + cos^-1(a) = pi/2\) (using the identity \(sin^-1(x) + cos^-1(x) = pi/2\))

So, \(sin^-^1(beta) = pi/2 - cos^-^1(a)\)

Substituting the given value, we get:

\(pi/2 - cos^-^1(a) = pi/2 - cos^-^1(a)\)

This is true for any value of a and β. Therefore, we cannot determine the value of β from the given equation.

The parameterized plane that contains the three points is r(s,t) = (1,−2,−5) + s(−11,−4,−7) + t(14,22,15).

To parameterize the plane that contains the three points (1,−2,−5), (−10,−6,−12), and (15,20,10), we can use a vector equation.

We can choose any of the given points as r. Let's choose (1,−2,−5) as our r

r = (1,−2,−5).

To find v, we need to subtract r from any two points on the plane. Let's choose (−10,−6,−12) and (15,20,10) as our points.

⃗v = (−10,−6,−12) - (1,−2,−5) = (−11,−4,−7).

Similarly, we can subtract r from another pair of points. Let's choose (−10,−6,−12) and (15,20,10) again.

⃗w = (15,20,10) - (1,−2,−5) = (14,22,15).

Now we have all the necessary components to parameterize the plane.

r(s,t) = (1,−2,−5) + s(−11,−4,−7) + t(14,22,15).

The matrix shown represents its elements in rows and columns

Using the assumed matrix, the operation performed on the initial matrix to determine the new resultant matrix is R3 -> 2R2 + R3.

The question is incomplete, as the matrix is not shown.

So, I will give a general explanation.

Assume that the matrix is given as:

\(\left[\begin{array}{cccc}-4&1&2&4&0&-1&3&1&3&2&4&5\end{array}\right]\)

Multiply the elements on the second row (Row 2) by 2.

So, we have:

2R2 = 0 -2 6 2

Add these elements to the third row (Row 3).

So, we  have:

2R2 + R3 = 3 0 10 7

Replace the row 3 by the above elements.

i.e.

R3 -> 2R2 + R3.

So, we have:

\(\left[\begin{array}{cccc}-4&1&2&4&0&-1&3&1&3&0&10&7\end{array}\right]\)

Inference is referred to as all the data collected in a particular study.

Etymologically, the word "infer" means to "carry ahead." Inferences are stages in reasoning that connect premises to logical conclusions. The dichotomy between deduction and induction in inference theory, which dates at least to Aristotle in Europe, is a classic one (300s BCE). Deduction is inference that results in logical conclusions from premises that are known to be true or that are presumed to be true, while the logic of correct inference is investigated. A universal conclusion is inferred by induction from specific evidence. Contradistinguishing abduction from induction, Charles Sanders Peirce is credited with identifying a third sort of inference. Researchers in the domains of logic, argumentation studies, and cognitive psychology traditionally study human inference (i.e., how people draw conclusions); artificial intelligence researchers create automated inference systems to mimic human inference.

Answer:

3.6% per annum

Step-by-step explanation:

The formula for accrued amount on a loan(value of loan) is given by the formula if compounded yearly is

\(A = P\left(1 + r)^t\)

where

P = original loan amount

r = interest rate in decimal

t = number of years

We are given that the original loan amount
P = £5500

After 1 year the accrued amount
\(A = 5500(1 + r)^1\)

and we know that after 1 year, the value of the loan is £5698

Therefore

5698 = 5500(1 + r)

1+ r = 5698/5500 = 1.036

r= 1.036 - 1 = 0.036

In percentage terms 0.036 = 0.036 x 100 = 3.6%

The standard deviation of the heights of the 100 students is calculated to be 8.2 cm, since a probability of 0.25 corresponds to a height of 180 cm.

The standard deviation of a normal distribution can be calculated by finding the distance between the mean and the point at which a certain probability occurs. In this instance, the mean of the heights of 100 students is 172 cm and the probability of a height above 180 cm is 0.25. This means that the distance between the mean of 172 cm and the point corresponding to a probability of 0.25 is 180 cm. Therefore, the standard deviation of the heights of the 100 students is 8.2 cm, since a probability of 0.25 corresponds to a height of 180 cm. This can be confirmed by using a normal distribution calculator, which will provide the same result.

Dissonance is a combination of notes that sound unpleasant or harsh. Dissonant interval examples are major and minor seconds, tritone, and major and minor sevenths. The consonant intervals are considered the perfect unison, octave, fifth, fourth and major and minor third and sixth, and their compound forms.

The value of the annuity at the end of 10 years is $59313.58.

Use a formula to determine the annuity in case of periodically deposit as

\(A = \dfrac{P[(1+r/n)^{nt}-1]}{\frac{r}{n} }\)

Where P is periodic deposit amount interests,

r rate annually is the number of times compounded annually and

t is time in a year.

We have been given that investment in an annuity that pays 6% interest, compounded annually. You contribute $4,500 each year for 10 years

Here,

P = $4500, r = 6% = 0.06,

t =10 years

n = 1 (annually)

\(A = \dfrac{P[(1+r/n)^{nt}-1]}{\frac{r}{n} }\)

Substitute the values of P, r, and t in the formula, we get

\(A = \dfrac{4500[(1+0.06/1)^{10}-1]}{\frac{0.06}{1} }\)

⇒ A = 4500[1.06¹⁰]/0.06

⇒ A = $59313.58

Therefore, the value of the annuity at the end of 10 years is $59313.58.
