What is the temperature in degrees Celsius that is equivalent to a temperature of 40 F?
Ludmilka [50]
Hi! So given the equation you are given, you plug in 40 for F, making your equation look like this: C=(5/9)(40-32). Using PEDMAS, Subtract 32 from 40 which gives you 8 and then multiply by 8. Your answer as an improper fraction should be 40/9 which you can then reduce to 4(4/9).

If two balls are taken, the probability that at least one has traditional insurance

TN or TM or TT or NT or MT

where T is for traditional insurance

N is for no insurance

M is for managed insurance

the probability that at least one of two people picked without replacement has traditional insurance

= 9/32 * 6/31 + 9/32 * 17/31 + 9/32 * 8/31 + 6/32 * 9/31 + 17/32 * 9/31

= (54 + 153 + 72 + 54 + 153)/992

= 486/992
