We have two points:
(-3,5) and (2,-3)

I
An equation in oint-slope form has this shape:
y-y₀=m(x-x₀)
m=slope

1) we compute the slope (m) between two points:
Given two points (x₁,y₁) and (x₂,y₂) the slope between these pointw will be.
m=(y₂-y₁)/(x₂-x₁)

In this case, our slope would be:
m=(-3-5)/(2+3)=-8/5

2) we choose one of these points and replace it in the equation, the result will be the same:
(-3,5)
<span>y-y₀=m(x-x₀)
</span>y-5=-8/5(x+3)

Answer: y-5=-8/5(x+3)

15 POINTS PLEASE ANSWER
faust18 [17]

Ok I have no idea if this is what it’s asking but I’ll give it a try

24inch=2 ft

2r=24 then r=12inch=1ft

V=πr^2.h

π.1.40= 40πft^3 so the answer I think is 40π

Determine the number of degrees of freedom for the two-sample t test or CI in each of the following situations. (Round your answ
tekilochka [14]

Answer:

a

  df =  24.32

b

 df = 30.10

c

 df = 30.7

d

df = 25.5

Step-by-step explanation:

Generally degree of freedom is mathematically represented as

          df =  \frac{ [\frac{ s^2_i }{m} + \frac{ s^2_j }{n} ]^2 }{ \frac{ [ \frac{s^2_i}{m} ]^2 }{m-1 }  +\frac{ [ \frac{s^2_j}{n} ]^2 }{n-1 }  }

Considering a

         a) m = 12, n = 15, s1 = 4.0, s2 = 6.0

           df =  \frac{ [\frac{ 4^2 }{12} + \frac{ 6^2 }{15} ]^2 }{ \frac{ [ \frac{4^2}{12} ]^2 }{12-1 }  +\frac{ [ \frac{6^2}{15} ]^2 }{15-1 }  }

         df =  24.32

Considering b

       (b) m = 12, n = 21, s1 = 4.0, s2 = 6.0

          df =  \frac{ [\frac{ 4^2 }{12} + \frac{ 6^2 }{21} ]^2 }{ \frac{ [ \frac{4^4}{12} ]^2 }{12-1 }  +\frac{ [ \frac{6^2}{21} ]^2 }{21-1 }  }

        df = 30.10

Considering c

      (c) m = 12, n = 21, s1 = 3.0, s2 = 6.0

           df =  \frac{ [\frac{ 3^2 }{12} + \frac{ 6^2 }{21} ]^2 }{ \frac{ [ \frac{3^4}{12} ]^2 }{12-1 }  +\frac{ [ \frac{6^2}{21} ]^2 }{21-1 }  }

           df = 30.7

Considering c

        (d) m = 10, n = 24, s1 = 4.0, s2 = 6.0

                df =  \frac{ [\frac{ 4^2 }{10} + \frac{ 6^2 }{24} ]^2 }{ \frac{ [ \frac{4^2}{10} ]^2 }{10-1 }  +\frac{ [ \frac{6^2}{24} ]^2 }{24-1 }  }

               df = 25.5
