The total number of students is 14+36, or 50. So the chance that a selected student is female is 36/50, or 18/25.
Answer:
2415 Chinese yuan (rounded off to nearest yuan)
Step-by-step explanation:
£0.13 = 1 Chinese yuan
£314 = 
×1 Chinese yuan
= 2415 Chinese yuan (rounded off to nearest yuan)
One possible system is
1x + 3y = 4
2x + 6y = 8
Note how 2 is twice as large as 1, 6 is twice as large as 3, and 8 is twice as large as 4.
In other words, the second equation is the result of multiplying both sides of the first equation by 2.
1x+3y = 4
2*(1x+3y) = 2*4
2x+6y = 8
Effectively the two equations in bold are the same which produces the same line. The two lines overlap perfectly to intersect infinitely many times. An intersection is a solution.
Answer:
x = 5/42 or 0.119
Step-by-step explanation:
log(6x) + log(14) = 1
log(6x × 14) = 1
log(84x) =
84x = 10¹
84x = 10
x = 10/84
x = 5/42 or 0.119
