Sin2alpha+cos2alpha-cos6alpha/sin4alpha+2sin²alpha-1<br><br> if alpha is -135°​
balandron [24]

Answer:

=  \frac{\sin(2 \alpha )  +  \cos(2 \alpha )  -  \cos(6 \alpha ) }{ \sin(4 \alpha )  + 2 { \sin }^{2}  \alpha  - 1}  \\  =  \frac{ \sin( - 270) +  \cos( - 270)  -  \cos( - 810)  }{ \sin( - 540)  + 2 { \sin }^{2}( - 135) - 1 }  \\  =  \frac{1}{ - 2}  \\  =  - 0.5

The graph represents the normal distribution of recorded weights, in pounds, of cats at a veterinary clinic.
ICE Princess25 [194]

Answer:

The weights within this range are:

8.9

9.5

9.8

10.4


Step-by-step explanation:

The graph represents the normal distribution with a mean of 9.5 and a standard deviation of 0.5. Therefore, the range of the values within 2 standard deviations is:

9.5 - 2(0.5) ≤ x ≤ 9.5 + 2(0.5)

8.5 ≤ x ≤ 10.5
