Answer: 0.62
Step-by-step explanation:
Total people= 47
Let A be the event of selecting person was interested in trying the new drink.
Person not interested in trying a sample of a new soft drink (nA')=18
Person interested in trying a sample of a new soft drink (nA)=47-18=29
Thus probability that a randomly selected person was interested in trying the new drink
P (A) = 29/41 = 0.6170 (or) 0.62
Thus, probability that a randomly selected person was interested in trying the new drink is 0.62.
47-18=29 people interested in the new drink
29/47=0.617
0.617*100=61.7% chance

Answer y-2x+5 or it will be y=-2x+11
Step-by-step explanation:
Answer:
y=-3x^2+10 is a quadratic function, so Yes it is a function.
Part A:
C= a + bn
Make the two equations out of the words:
82 = a + b100 * 2.5 = 205 = a + b250
157 = a+ b250
Subtract the two,
205 = a + b250
- ( 157 = a + b250)
48 = a
Find b by substituting in a:
82 = a + b100
82 = 48 + b100
34 = b100
b = 0.34
Answer for part a: a = 48 , b = 0.34
Part B:
C = a +bn <- when n = 300 , put in a and b, then solve
C = 48 + 0.34(300)
C = 48 + 102
C = 150
