Answer:
C
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
Here [ a, b ] = [ - 10, 10 ], thus
f(b) = f(10) = 10² + 9(10) + 18 = 100 + 90 + 18 = 208
f(a) = f(- 10) = (- 10)² + 9(- 10) + 18 = 100 - 90 + 18 = 28, thus
average rate of change = 
= 
= 9
Answer:
C: 2; Allison, Richard, and Hope are right because the graph can have 0,1, or 2 x-intercepts.
X. 1. 2. 3. 4. 5. 6 are all the possible events when rolling a die. If it is a fair die then the probability of rolling any number is 1/6. So the probability of rolling at most a two is p(1)+ p(2)= 2/6 or 1/3
Answer
1. 90% 2. 10%
Step-by-step explanation:
50 /10=5 which means that 5 people equal 1 percent
45/50=.9
.9*100=90 which is the percent of right handed people
