7/8
Answers:
14/16- divide the denominator and numerator by 2. 14/2=7, 16/2=8 : 7/8
35/40- divide the denominator and numerator by 5. 35/5=7, 40/5=8 : 7/8
42/48- divide the denominator and numerator by 6. 42/6=7, 48/6=8 : 7/8
49/56- divide the denominator and numerator by 7. 49/7=7, 56/7=8: 7/8
Answer:
It is actually not any of the answers. It is actually 0.76
Step-by-step explanation:
Mean = (40.55 + 41.51 + 42.01 + 38.76 + 36.32 + 34.28 + 35.38 + 37.48 + 40.87 + 48.32 + 41.59 + 42.71)/12 = 39.98 seconds.
In this case, the outlier comes to be the data: 48.32. If we don't consider that data point, the mean equals:
Mean = (40.55 + 41.51 + 42.01 + 38.76 + 36.32 + 34.28 + 35.38 + 37.48 + 40.87 + 41.59 + 42.71)/11 = 39.22
The difference is: 39.98 - 39.22 = 0.76
F(x) is a polynomial so x∈R (all real numbers).
Answer:
f(- 2) = 8
Step-by-step explanation:
To evaluate f(- 2) substitute x = - 2 into f(x) , that is
f(- 2) = 2 - 4(- 2)³ - 11(- 2)² +3(- 2) - 6
= 2(16) - 4(- 8) - 11(4) - 6 - 6
= 32 + 32 - 44 - 12
= 64 - 56
= 8
