Answer:
Step-by-step explanation:
use the equation: y =50x-350 where x is the number of hours driving
hrs
1 50 300
2 100 250
3 150 200
5 250 100
7 350 0
6 = -2b (cancel -2b on both sides)
6/-2 = b (divide both sides by -2)
-3 = b (simplify 6/2 to 3)
now switch sides
Answer: b = -3
Try this option:
1] P(S)=0.84;
2] P(S or C, but not both)=0.4;
3] P(C)=0.76;
4] P(S∪C)=0.6;
5] P(C, but not S)=0.16;
6] P(S∩C)=1.00.
Answer:




Step-by-step explanation:
Required
Find n, x, p and q
n always represent the population surveyed;
So:

x represents the sample from the population
So:

p always represents the given proportion

Solving for q
