In one town 44% of all voters are Democrats if two voters are randomly selected for a survey find the probability that they are
kenny6666 [7]

Answer:

0.194


Step-by-step explanation:

Probability that BOTH are democrats means probability of <u>"one being democrat"</u> AND <u>"another also being democrat"</u>.

The AND means we need to MULTIPLY the individual probability of a person being democrat.

Probability that a voter is democrat is 44% (0.44) -- stated in the problem


Now, Probability BOTH being Democrats is simply MULTIPLYING 0.44 with 0.44

0.44*0.44=0.1936

Rounded to nearest thousandth, 0.194

Last answer choice is correct.

Answer:2516 pounds

Step-by-step explanation:

find the difference in gallons and the difference in the weights

46 - 14 = 32 gallons

2399 - 2191 = 208 pounds

 so 32 gallons of gas weighs 208 pounds

find weight per pound: 208 pounds / 32 gallons = 6.5 pounds per gallon

 round to 6.5 pounds per gallon

64 gallons - 46 gallons = 18 gallons

 18 gallons x 6.5 pounds per gallon = 117 pounds

2399 + 117 = 2516  weight of plane with 64 gallons
