A job calls for installing 270 lighting fixtures. If 81 fixtures have been installed so far, what percent of the job still has to be done?

70%

Step-by-step explanation:

First find the ones that still need to be installed

270-81

189

Percent to be done = number to be installed / total

                                   =189/270 =.7

Change to percent form = .7 *100% = 70%

A: The correlation is strong and positive

B: The correlation is weak and negative

C: The correlation is strong and positive

D: The correlation is strong and negative

explanation:
