Answer:
0.0462 ± 2.131(0.01565)
Step-by-step explanation:
The confidence interval for the slope, :
Slope Coefficient = 0.0462
Slope Coefficient ± Margin of error
Margin of Error = Tcritical * standard error
Standard Error (rotation) = 0.01565
We use T distribution, because sample size is small ; n = 16
Tcritical at 95% ; df = n - 1 = 16 - 1 = 15
Tcritical(0.05, 15) = 2.131
Hence,
Margin of Error = 2.131(0.01565)
Slope Coefficient for rotation = 0.0462
95% Confidence interval :
0.0462 ± 2.131(0.01565)
The 95% confidence interval for the slope of the regression line is 0.0462 ± 0.0333 or (0.01284, 0.07955)
What is the margin of error?The probability or the chances of error while choosing or calculating a sample in a survey is called the margin of error.
Slope coefficient = 0.0462
Slope coefficient ± Margin of error
The margin of error will be given as
[tex]\rm Margin \ of \ error = T_{critical} \times standard \ error[/tex]
Standard error = 0.01565
We use T distribution because the sample size is small
[tex]\rm n = 16 \\\\T_{critical} \ at \ 95\% \ ; df = n-1 = 16- 1 = 15\\\\T_{critical} \ (0.05, 15) = 2.131[/tex]
Then we have
Margin of error = 2.131 × 0.01565
Margin of error = 0.0333
Then the 95% confidence interval will be
0.0462 ± 0.0333

Answer:
Option E
Step-by-step explanation:
GIVEN :-
β ≠ 3γTO FIND :-
Value of xSOLTION :-
[tex]x - \frac{\beta x}{3\gamma} = \alpha[/tex]
Take 'x' common from L.H.S.
⇒ [tex]x ( 1 - \frac{\beta}{3\gamma} ) = \alpha[/tex]
Substract the terms in the brackets
⇒ [tex]x (\frac{3\gamma - \beta }{3\gamma} ) = \alpha[/tex]
Now , take the whole term in brackets to R.H.S.
⇒ [tex]x = \frac{\alpha }{\frac{3\gamma - \beta }{3\gamma} } = \alpha(\frac{3\gamma}{3\gamma - \beta}) = \frac{3 \alpha \gamma}{3\gamma - \beta }[/tex]
CONCLUSION :-
∴ [tex]x = \frac{3 \alpha \gamma}{3\gamma - \beta }[/tex] (Option E)

Step-by-step explanation:
The surface area the sphere is 64π cm².
SphereA sphere is a three-dimensional equivalent of a two-dimensional circle. A sphere is a collection of points in three-dimensional space that are all the same distance r from a particular point. hat given point is the center of the sphere, and r is the sphere's radius
Surface area: 4πr²
How to determine the surface area of the sphere?Given the radius of the sphere is 4 cm.
then apply the formula
surface area = 4π(4)²
= 4π(16)
= 64π cm²
Hence the surface area is 64π cm².

Please!! What is the slope of each line?
Are they the same or different?
Given:
The graph of two lines.
To find:
The slope of each line and check whether they are same or different.
Solution:
If a line passes through two points, then the slope of a line is:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
From the graph 1, it is clear that the line passes through the points (2,175) and (3,165). So, the slope of first line is:
[tex]m_1=\dfrac{175-165}{3-2}[/tex]
[tex]m_1=\dfrac{10}{1}[/tex]
[tex]m_1=10[/tex]
The slope of first line is 10.
From the graph 2, it is clear that the line passes through the points (1,175) and (2,165). So, the slope of first line is:
[tex]m_2=\dfrac{175-165}{2-1}[/tex]
[tex]m_2=\dfrac{10}{1}[/tex]
[tex]m_2=10[/tex]
The slope of second line is 10.
[tex]m_1=m_2[/tex]
Therefore, the slopes of both lines are same, i.e. 10.

For the simple harmonic motion equation d=2 sin(pi/3 t), what is the frequency? If necessary, use the slash (/) to denote a fraction.
Answer:
The frequency is f = 1/T = 1/2 Hz.
Step-by-step explanation:
The frequency of a simple harmonic motion equation can be found by taking the inverse of the period. The period of a simple harmonic motion equation is the time it takes for the motion to repeat itself. In the equation d=2 sin(pi/3 t), the period is T = 2*(pi/3)/(pi/3) = 2 seconds. Therefore, the frequency is f = 1/T = 1/2 Hz.

Function DefinitionA function connects various inputs together or produces a single output from each input. Simply explained, a function is a collection of equations that are linked to a single, identifiable output. A statement, rule, or law which explains the connection between two variables is known as a function in mathematics (the dependent variable). When a rule of this type is applied, there is just one output. by photographer Alex Federspiel.
Here,
=> (1−α)(1−β)(1+α)(1+β)
=>(1−α−β+αβ) /(1+α+β=αβ)
=> (1−(α+β)+αβ ) / ( 1+(α+β)+αβ)
=>(1 + 2/3 + 1/3 )/ (1 -2/3 + 1/3)
=> 2 x 3 /2 =3
=> (1−α)(1+β)+(1−β)(1+α) / (1+α+β+αβ)
=> 3(2−2αβ)/2
=>3(1−αβ)

$34,100 at 4% for 3 years
Simple interest
The 3 year simple interest at 4% will be $38,192.
What is Simple interest?A quick and easy method of calculating the interest charge on a loan is called a Simple interest.
The principal amount = $34,100
Interest rate = 4%
Time = 3 years Now,
Since, We know that;
Where, A is final amount.
P is principal amount.
r is interest rate.
t is time.
Substitute all the values, we get;
A = $34,100 (1 + 4/100)³
A = $34,000 (104/100)³
A = $34,000 × 104/100 × 104/100 × 104/100
A = $38,192
Thus, The Simple interest will be $38,192.
