Month_1 Value = Month_0 Value * 0.95

Month_2 Value = Month_1 Value * 0.95 = Moth_0 Value * 0.95*0.95 = Month_0 Value * 0.95^2

Month _n Value = Month_0 Value * (0.95)^n

After 2 years ==> n = 24

Month_24 Value = Month_0 Value * (0.95)^24 = 2,000,000 *(0.95)^24 = 583,978.05

Solve the system using substitution:<br> y = -6x + 7<br><br> 3x – 2y = 16<br><br> helppp
bearhunter [10]

Answer:

x=-6 y=-1

Step-by-step explanation:

// Solve equation [2] for the variable  y  

 

 [2]    y = -x - 7

// Plug this in for variable  y  in equation [1]

  [1]    3x - 2•(-x -7) = -16

  [1]    5x = -30

// Solve equation [1] for the variable  x  

  [1]    5x = - 30  

  [1]    x = - 6  

// By now we know this much :

   x = -6

   y = -x-7

// Use the  x  value to solve for  y  

   y = -(-6)-7 = -1  

Solution :

{x,y} = {-6,-1}

What are all solutions to the differential equation dy/dx=sec^2*x ?
zysi [14]

Answer:

y=tanx+C

Step-by-step explanation:

\frac{dy}{dx}  =  {sec}^{2}  \: x \\  \\ dy = {sec}^{2}  \: x \: dx \\  integrating \: both \: sides \\  \\  \int \:1\: dy =  \int {sec}^{2}  \: x \: dx \\  \\  \huge \red{ \boxed{ \therefore \: y = tan \: x + c}} \\

In a hypothesis test, what should we conclude if the data would be very unusual if the original assumption about our parameter w
Triss [41]

We conclude  the hypothesis test as Alternative Hypothesis if the data would be very unusual if the original assumption about our parameter were correct.

  • A hypothesis in statistics is a claim or supposition on the properties of one or more variables in one or more populations. There are two hypothesis to choose between because a statement might either be true or wrong.
  • The null hypothesis is the assertion that we (or someone else) consider to be true. Our hypothesis test will come to one of two conclusions: "reject H0" or "do not reject H0." Remember that until data provide evidence to the contrary, we always proceed under the null hypothesis.
  • If the null hypothesis is incorrect, the alternative hypothesis must be true. The hypothesis test can be different in one of three ways: greater than, smaller than, or just different (not equal). As a result, there will always be an inequality requirement in the notation for H.
