Question 1(Multiple Choice Worth 1 points)
2 answers:
If you can't tell "by inspection" or by computing the change in y (-16) divided by the change in x (4) as -4, then you can always check to see which of the equations predicts the proper value for y.
1) (1/4)*(-4) = -1, not 16
2) 4*(-4) = -16, not 16
3) (-1/4)*(-4) = 1, not 16
4) -4*(-4) = 16 . . . . as required
The 4th selection is appropriate.

Answer: 0.62
Step-by-step explanation:
Given : A recent Harris Poll survey of 1010 U.S. adults selected at random showed that 627 consider the occupation of firefighter to have very great prestige.
i.e. The sample size of U.S. adults : n= 1010
The number of U.S. adults consider the occupation of firefighter to have very great prestige : x= 627
Now , the probability that a U.S adult selected at random thinks the occupation of firefighters has very great prestige will be :
[ To the nearest hundredth]
Hence, the estimated probability that a U.S adult selected at random thinks the occupation of firefighters has very great prestige = 0.62
