What is the critical value t* which satisfies the condition that the t distribution with 14 degrees of freedom has probability 0

.35 to the right of t*
Mathematics
1 answer:
Oduvanchick [21]2 years ago

Answer:

t_{0.35,14}= 0.3933306

Step-by-step explanation:

From the question we are told that:

Degree of freedom df=14

Significance Level \alpha=0.35

Generally the expression for critical value t is mathematically given by

  t_{\alpha,df}

  t_{0.35,14}

Therefore From Students T Value Table

 t_{0.35,14}= 0.3933306

 T-Value (right-tailed): 0.3933306

How do I do this ? I don't know how to find the midpoint in this problem
finlep [7]
If point A is the midpoint then that means line segments XA and AY are equivalent so you can set:
3x=5x-6
(now you solve for x)
2x=6
(divide by 2 on both sides)
x=3

So BASICALLY,
XA= 3x= 3(3) = 9
AY= 5x-6= 5(3)-6 =9
So now you know the length of both sides, add those together and you get 
XY=18

Find the solution:<br> 3x + 2y = 12<br> -2x + 3y = 5
finlep [7]

Answer:

x = 3

y = 2

Step-by-step explanation:

3x + 2y = 12

-2x + 3y = 5 to find the solution we will use elimination method and for that, multiply second equation with 3 and the first equation with 2

<em>2 * 3x + 2y = 12</em>

<em>6x + 4y = 24</em>

<u>3 * -2x + 3y = 5</u>

<u>-6x + 9y = 15</u>  now find the sum of both equation:

<em>6x + 4y  </em><u>-6x + 9y</u> = 24 + 15 add like terms

13y = 39 divide both sides by 13

y = 3 now that we found the value of y we can use this to calculate the value of x

3x + 2y = 12 replace y with 3

3x + 2*2 = 12

3x + 4 = 12 subtract 4 from both sides

3x = 9 divide both sides by 3

x = 3

Dominik [7]

Answer:

\large \boxed{\$4100.07}

Step-by-step explanation:

The formula for the future value (FV) of an investment earning compound interest is

FV = PV \left (1 + \frac{r}{n} \right )^{nt}

where

PV = the present value (PV) of the money invested

  r = the annual interest rate expressed as a decimal fraction

  t = the time in years

 n = the number of compounding periods per year

Data:

FV = $7100

  r =  8 % = 0.08

  t = 7 yr

 n = 2

Calculation:

\begin{array}{rcl}\\7100& =& PV \left (1 + \dfrac{0.08}{2} \right )^{2 \times 7}\\\\& =& PV (1 + 0.04)^{14}\\\\& =&PV (1.04)^{14}\\& =& PV(1.731676)\\PV& =& \dfrac{7100}{1.731676}\\\\& =& \mathbf{4100.07}\\\end{array}\\\text{The present value of the money is $\large \boxed{\mathbf{\$4100.07}}$}

Please answer !!!!!!!!!!!!!!!!! need it
Montano1993 [528]
B because if you reflect on x= -1 it would look like the “y” line moved to the left one because it’s x= -1, So you reflect along that new line. Then translate down the amount it said to. Hope this made sense
