The discriminant can be determined from the number of roots of the graph.

If Disc> 0, the function has two distinct roots
If Disc = 0, the function has a repeated root
If Disc < 0, the function has no real root.

Since the given graph has no real root, i.e. it does not cross x-axis at any point, so we can say that the discriminant of the given function is negative.

So the answer to this question is option C

Please help i need help on question b
anzhelika [568]

There are 12 possible outcomes.....three of these will be a "7"  ...so...

A "7" should occur  1/4 of the time

If each player pays 20p to play.....the school  will take in  120 * 20  = 2400p

However.......1/4 of the players should win =  30 players.....and each lollipop costs 30p.....so......the school should spend 30 * 30  = 900p for the prizes

So......the school should raise   2400 - 900 = 1500p  if 120 people play the game

dezoksy [38]
Given: Security Service Company:
1.4 1.8 1.6 1.7 1.5 1.5 1.7 1.6 1.5 1.6
Mean: 1.59
Standard Deviation: 0.014333

Other companies: 1.8 1.9 1.6 1.7 1.6 1.8 1.7 1.5 1.8 1.7
Mean: 1.71
Standard deviation: 0.014333

The coefficient of variation for security Service Company:

CV = (Standard Deviation/Mean) * 100.

= (0.14333/1.59) * 100

= 9.01%

The coefficient of variation for other companies:

CV = (Standard Deviation/Mean) * 100.

= (0.014333 / 1.71) * 100

= 8.38%

the limited data listed here show evidence of stealing by the security service company's employees because there is a significant difference in the variation.
