Suppose you are testing the sample is small (n = 6) and the data come from a normal population. the variance, σ2, is unknown. (a) find the critical value(s) corresponding to α = 0.20. (b) you find that t = −1.71. based on your critical value, what decision do you make regarding the null hypothesis (i. e. do you reject h0 or do not reject h0)?

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

step-by-step explanation:

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
