Sample statistics play a very critical role in determining whether to "reject the null hypothesis" or "do not reject the null hypothesis."
In hypothesis testing, the null hypothesis represents the claim or assumption being tested, while the alternative hypothesis proposes a different claim. The goal is to assess the evidence provided by the sample data to make a decision about the null hypothesis.
To make this decision, statistical tests are performed using the sample data. These tests involve calculating sample statistics, such as means, proportions, or test statistics, which are compared to the expected values under the null hypothesis.
By comparing the sample statistics to the expected values, we can assess whether the observed data is consistent with the null hypothesis or suggests evidence against it. If the sample statistics provide strong evidence against the null hypothesis, we may reject it in favor of the alternative hypothesis. On the other hand, if the sample statistics do not provide sufficient evidence, we do not have enough grounds to reject the null hypothesis.
Therefore, sample statistics play a crucial role in determining whether to "reject the null hypothesis" or "do not reject the null hypothesis" based on the evidence provided by the sample data.

f(x)=x^2−4x+8, [0,4]
when, x = 0
f(x) = x^2 -4x +8
f(0) = y = 0 - 0 + 8 = 8
when, x=4
f(5) = y = 16 - 16+8 =
thus, we have 2 points (0, 8) ; (4, 8)
slope,m = {8-(8)} / {4-0} = 0
hence, we have to calculate all the points,x where 0<x<8 and slope=0
f '(x) = 2x - 4 = 0
or, f '(c) = 2c - 4 = 0
c = 4/2 =2 ( 0<x<4)

TRUE OR FALSE: The alternative hypothesis states that there is no difference/no effect.
The answer is FALSE. The alternative hypothesis is a statement that there is a difference or an effect in the population being studied, and it contradicts the null hypothesis, which is a statement that there is no difference or no effect in the population being studied.
The alternative hypothesis is a statement that contradicts the null hypothesis and is generally the hypothesis that the researcher wants to support. It is a statement that there is a difference or an effect in the population being studied.
In hypothesis testing, the null hypothesis is a statement that there is no difference or no effect in the population being studied. The null hypothesis is typically the default hypothesis, which is assumed to be true unless evidence suggests otherwise. The alternative hypothesis, on the other hand, is a statement that there is a difference or an effect in the population being studied, and it is typically the hypothesis that the researcher wants to support.
For example, if a researcher wants to test the effectiveness of a new drug, the null hypothesis might be that the drug has no effect on the condition being treated, while the alternative hypothesis might be that the drug has a positive effect on the condition being treated.
In summary, the alternative hypothesis is a statement that there is a difference or an effect in the population being studied, and it contradicts the null hypothesis, which is a statement that there is no difference or no effect in the population being studied.

In the expansion of (2a + 4b)8, which of the following are possible variable terms? Explain your reasoning.
a2b3; a8; a5b3; ab8; a3b5; a7b; a6b5; b8
In the expansion of (2a+4b)⁸ the possible variable terms are a⁸, a⁵b³, a³b⁵, a⁷b, and b⁸.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
The expansion is given by the following formula: \(\left(a + b\right)^{n} = \sum_{k=0}^{n} {\binom{n}{k}} a^{n - k} b^{k}\), where \({\binom{n}{k}} = \frac{n!}{\left(n - k\right)! k!}\)
As given to us, a = 2a, b = 4 b, and n = 8.
Therefore, \(\left(2 a + 4 b\right)^{8} = \sum_{k=0}^{8} {\binom{8}{k}} \left(2 a\right)^{8 - k} \left(4 b\right)^{k}(2a+4b)\).
Thus, \(\left(2 a + 4 b\right)^{8} = 256 a^{8} + 4096 a^{7} b + 28672 a^{6} b^{2} + 114688 a^{5} b^{3} + 286720 a^{4} b^{4} + 458752 a^{3} b^{5} + 458752 a^{2} b^{6} + 262144 a b^{7} + 65536 b^{8}.\)
Hence, In the expansion of (2a+4b)⁸ the possible variable terms are a⁸, a⁵b³, a³b⁵, a⁷b, and b⁸.

the perimeter of the triangle below is 38 units. Find the length of side WX. Write your answer without variables
Answer:
5.5
Step-by-step explanation:
Add each side of the triangle.
3z+z+1+4z-3 = 8z - 2
8z - 2 is equivalent to the perimeter.
Since you know the perimeter is 38 units, you can set 8z-2 to 38.
8z-2 = 38
Solve for z. Subtract 2 from each side.
8z = 36
Divide each side by 8.
z = 4.5
Now solve for side WX.
WX = z + 1
WX = 4.5 + 1
WX = 5.5

Linea 6: cada 45 minutos linea 15: cada 15 minutos linea 10: cada 30 minutos rapidos por autopista: cada 90 minutos ¿coinciden en algun momentos todas las lineas, menos el rapido? Explica tu respuesta
Answer:
Las tres líneas coinciden cada 90 minutos, es decir, al mismo tiempo que pasa el Rápido, con lo cual en ningún momento coinciden todas las líneas menos el Rápido.
Step-by-step explanation:
Dado que la Línea 6 pasa cada 45 minutos, la Línea 15 pasa cada 15 minutos, la Línea 10 pasa cada 30 minutos, y los Rápidos por autopista pasan cada 90 minutos, para determinar si coinciden en algún momento todas las líneas, menos el rápido, se deben realizar los siguientes cálculos:
Línea 6 = 00:45, 01:30, 02:15, 03:00
Línea 15 = 00:15, 00:30, 00:45, 01:00, 01:15, 01:30, 01:45, 02:00, 02:15, 02.30, 02:45, 03:00
Línea 10 = 00:30, 01:00, 01:30, 02:00, 02:30, 03:00
Rápido = 01:30, 03:00
Así, como puede verse, las tres líneas coinciden cada 90 minutos, es decir, al mismo tiempo que pasa el Rápido, con lo cual en ningún momento coinciden todas las líneas menos el Rápido.

Consider two linear transformations:Rα :R2 →R2 and Rβ :R2 →R2given by rotation counter-clockwise around the origin by α and β, respectively.(a) Describe the composition Rα ◦ Rβ geometrically. What is it doing to the space R2? (b) Find the standard matrix of the composition Rα ◦ Rβ , using your answer to (a).(c) Find the standard matrix of the composition Rα ◦ Rβ a different way.(d) Use your answers to (b) and (c) to derive formulas for sin(α + β) and cos(α + β).
a) The composition Rα ◦ Rβ rotates the space R2 by an angle of (α + β) counter-clockwise around the origin.
b) The standard matrix of Rα ◦ Rβ is \begin{bmatrix} cos(α + β) & -sin(α + β) \ sin(α + β) & cos(α + β) \end{bmatrix}.
c) The standard matrix of Rα ◦ Rβ is calculated by multiplying the standard matrices of Rα and Rβ.
d) The formulas for sin(α + β) and cos(α + β) in terms of sin(α), sin(β), cos(α), and cos(β) are: sin(α + β) = sin(α)cos(β) + cos(α)sin(β) and cos(α + β) = cos(α)cos(β) - sin(α)sin(β).
a) Geometrically, the composition Rα ◦ Rβ is the rotation of R2 counter-clockwise around the origin by an angle of (α + β). This is because Rα rotates R2 counter-clockwise around the origin by an angle of α, and Rβ rotates R2 counter-clockwise around the origin by an angle of β. This composition is therefore rotating the space R2 by an angle of (α + β).
b) The standard matrix of the composition Rα ◦ Rβ is:
\begin{bmatrix}
cos(α + β) & -sin(α + β) \\
sin(α + β) & cos(α + β)
\end{bmatrix}
c) We can also use the properties of matrix multiplication to find the standard matrix of the composition Rα ◦ Rβ. We know that the standard matrices for Rα and Rβ are:
Rα = \begin{bmatrix}
cos(α) & -sin(α) \\
sin(α) & cos(α)
\end{bmatrix}
Rβ = \begin{bmatrix}
cos(β) & -sin(β) \\
sin(β) & cos(β)
\end{bmatrix}
Therefore, the standard matrix of the composition Rα ◦ Rβ is:
Rα ◦ Rβ = \begin{bmatrix}
cos(α)cos(β) - sin(α)sin(β) & -sin(α)cos(β) - cos(α)sin(β) \\
cos(α)sin(β) + sin(α)cos(β) & sin(α)sin(β) + cos(α)cos(β)
\end{bmatrix}
d) By comparing our two standard matrices for Rα ◦ Rβ, we can see that:
sin(α + β) = sin(α)cos(β) + cos(α)sin(β)
cos(α + β) = cos(α)cos(β) - sin(α)sin(β)
Therefore, the composition of Rα and Rβ rotates the space R2 by an angle of (α + β) counter-clockwise around the origin, and its standard matrix is calculated by multiplying the standard matrices of Rα and Rβ.

Write the first five digits of 1/7 in base 9 expression
Compare 1/7 to consecutive multiples of 1/9. This is easily done by converting the fractions to a common denominator of LCM(7, 9) = 63:
1/9 = 7/63
2/9 = 14/63
while
1/7 = 9/63
Then 1/7 falls between 1/9 and 2/9, so 1/7 = 1/9 plus some remainder. In particular,
1/7 = 1/9¹ + 2/63.
We do the same sort of comparison with the remainder 2/63 and multiples of 1/9² = 1/81. We have LCM(63, 9²) = 567, and
1/9² = 7/567
2/9² = 14/567
3/9² = 21/567
while
2/63 = 18/567
Then
2/63 = 2/9² + 4/567
so
1/7 = 1/9¹ + 2/9² + 4/567
Compare 4/567 with multiples of 1/9³ = 1/729. LCM(567, 9³) = 5103, and
1/9³ = 7/5103
2/9³ = 14/5103
3/9³ = 21/5103
4/9³ = 28/5103
5/9³ = 35/5103
6/9³ = 42/5103
while
4/567 = 36/5103
so that
4/567 = 5/9³ + 1/5103
and so
1/7 = 1/9¹ + 2/9² + 5/9³ + 1/5103
Next, LCM(5103, 9⁴) = 45927, and
1/9⁴ = 7/45927
2/9⁴ = 14/45927
while
1/5103 = 9/45927
Then
1/5103 = 1/9⁴ + 2/45927
so
1/7 = 1/9¹ + 2/9² + 5/9³ + 1/9⁴ + 2/45927
One last time: LCM(45927, 9⁵) = 413343, and
1/9⁵ = 7/413343
2/9⁵ = 14/413343
3/9⁵ = 21/413343
while
2/45927 = 18/413343
Then
2/45927 = 2/9⁵ + remainder
so
1/7 = 1/9¹ + 2/9² + 5/9³ + 1/9⁴ + 2/9⁵ + remainder
Then the base 9 expansion of 1/7 is

★ Firstly, we have to find the amount:
According, to the question by using the formula, we get:
\( \longmapsto \: { \bold{ \boxed{\pink{ \rm{A \: = P \left( 1 + \frac{ \frac{r}{2} }{100} \right)^{2n} }}}}}\)
Here,
Amount (A) = A Principal (P) = Rs 5000 Rate of Interest (r) = 10% p.a Time Period (n) = 2 yearsSo by putting their values, we get:
\( { \large{\longrightarrow{ \rm{A = 5000 \left( 1 + \frac{ \frac{10}{2} }{100} \right)^{2 \times 2} }}}}\)
\( { \large{ \longrightarrow{ \rm{A = 5000 \left( 1 + \frac{10}{2} \times \frac{1}{100} \right)^{4} }}}}\)
\( {\large{ \longrightarrow{ \rm{A = 5000 \left( 1 + \frac{10 \times 1}{2 \times 100} \right)^{4} }}}}\)
\({ \large{ \longrightarrow{ \rm{A = 5000 \left(1 + \frac{10}{200} \right)^{4} }}}}\)
\({ \large \longrightarrow {\rm{A =5000 \left( \frac{200 \times 1 + 10}{200} \right)^{4} }}}\)
\({ \large \longrightarrow{ \rm{A = 5000 \left( \frac{200 + 10}{200} \right)^{4} }}}\)
\({ \large{ \longrightarrow{ \rm{A = 5000 \left( \frac{210}{200} \right)^{4} }}}}\)
\({ \large{ \longrightarrow{ \rm{A = 5000 \left( \frac{210}{200} \times \frac{210}{200} \times \frac{210}{200} \times \frac{210}{200} \right)}}}}\)
\({ \large{ \longrightarrow{ \rm{A = 5000 \left( \frac{210 \times 210 \times 210 \times 210}{200 \times 200 \times 200 \times 200} \right)}}}}\)
\({ \large{ \longrightarrow{ \rm{A = 5000 \left( \frac{1944810000}{1600000000} \right)}}}}\)
\({ \large{ \longrightarrow{ \rm{A = 5000 \times \frac{1944810000}{1600000000} }}}}\)
\({ \large{ \longrightarrow{ \rm{A = 5000 \times \frac{194481}{160000} }}}}\)
\({ \large{ \longrightarrow{ \rm{A = 5 \times \frac{194481}{160} }}}}\)
\({ \large{ \longrightarrow{ \rm{A = \frac{972405}{160} }}}}\)
\({ \large{ \longrightarrow{ \rm{A = 6077.53 \: (approx.)}}}}\)
Hence, the amount is Rs 6078.
★ Now, we have to find the compound Interest:
According, to the question by using the formula, we get:
\({ \large{ \dashrightarrow{ \boxed{\green{ \rm{Compound \: Interest = A \: - \: P}}}}}}\)
Here,
Amount (A) = Rs 6078 Principal (P) = Rs 5000So, by putting their values we get:-
\( { \large{ \dashrightarrow{ \rm{Compound \: Interest = Rs \: 6078 \: - \: Rs \: 5000}}}}\)
\({ \large{ \dashrightarrow{ \rm{Compound \: Interest = Rs \: 1078}}}}\)
Hence, Compound Interest is Rs 1078.

find the slope of the tangent line at t = -1. b) find the points where the tangent is vertical or horizontal.
To find the slope of the tangent line at t = -1, we need to take the derivative of the function with respect to t and evaluate it at t = -1. We have the derivative, we substitute t = -1 to find the slope of the tangent line at that point.
The points where the tangent line is vertical or horizontal occur when the derivative is either undefined or equal to zero.
To find the slope of the tangent line at t = -1, we differentiate the given function with respect to t. Let's assume the function is denoted by y(t). We calculate dy/dt, which represents the derivative of y with respect to t. Once we have the derivative, we substitute t = -1 to find the slope of the tangent line at that point.
To find the points where the tangent line is vertical or horizontal, we set the derivative equal to zero and solve for t. This will give us the values of t where the tangent line is horizontal. To find the points where the tangent line is vertical, we look for values of t where the derivative is undefined. These points correspond to vertical tangents on the graph of the function.
