A) 81
B) 57
C) 36
D) 25
Correct Answer: A
Solution :
(a): If y is the temperature in degree Celsius then the corresponding Temperature in Fahrenheit is given as, \[y=\frac{9}{5}x+32\] \[\therefore \]Variance is multiplied by \[{{\left( \frac{9}{5} \right)}^{2}}\] i.e., by\[\frac{81}{25}\] \[\therefore {{(Var)}_{in{}^\circ F}}=\frac{81}{25}\times {{(Var)}_{in{}^\circ C}}=\frac{81}{25}\times {{5}^{2}}=81\]
