For each statement, select the correct null hypothesis, h0, and alternative hypothesis, ha, in symbolic form. (a) according to the merck veterinary manual, the average resting heart rate for a certain type of sheep dog is 115 beats per minute (bpm). a montana farmer notices his aging sheep dog has been acting more lethargic than usual and wonders if her heart rate is slowing. he measures her heart rate on 15 occasions and finds a sample mean heart rate of 118.2 bpm.

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system

then

hello there!

i believe the answer is

(cot2+1)/sec2=cot2

    csc2/sec2=cot2

  (1/sin2)/(1/cos2)=cot2

  (1/sin2)(cos2/1)=cot2

  cos2/sin2=cot2

  (1/tan2)=cot2

  (cot2)=(cot2)

hope this !
