If 2 sec2 θ - 9 sec θ + 7 = 0, then what is the value of cos2 θ + sec2 θ ?
The table given below shows the production of bike and truck by five companies.
| Companies | Production | |
| Bike | Truck | |
| A | 300 | 200 |
| B | 175 | 100 |
| C | 200 | 50 |
| D | 75 | 250 |
| E | 100 | 275 |
J1 = The average production of bike by all the 5 companies.
J2 = The average production of truck by all the 5 companies.
What is the value of (J1 : J2)?
What is the value of \(\frac{5}{12}\text{ of }\frac{6}{25}-\frac{5}{6}\times\frac{12}{33}+\frac{5}{11}\div\frac{25}{33}\) \(\frac{6}{6}\div\frac{1}{2}+\frac{6}{6}\times\frac{1}{2}-\frac{1}{2}\text{ of }\frac{1}{6}\) ?
\(\frac{131}{110}\)
\(\frac{125}{117}\)
\(\frac{121}{112}\)
\(\frac{133}{115}\)
