<u>Step-by-step explanation:</u>
Here we have , Based on a survey, that 46% of consumers are comfortable having drones deliver their purchases. Suppose that we want to find the probability that when five consumers are randomly selected, exactly three on them are comfortable with delivery by drones. We need to find the values of n,x,p,and q .Let's find out:
According to question , 46% of consumers are comfortable having drones deliver their purchases , So , Probability of success :
⇒ 
And , probability of failure :
⇒ 
⇒ 
Now , n = Number of people randomly selected = 5
x = Number of people exactly comfortable = 3
Therefore , .

Answer:
50
Step-by-step explanation:
she starts with 9 plus the 10. so she has 19. Danny takes 4 so she has 15. then she trades so she gets 3 per marble she trades so it's like 15 times 3 which is 45. plus the 7 her parents gave her which is 52 and she gives 2 to her sister. so it's 50
Answer:
It is b.
Step-by-step explanation:
When x is negative x^5 will also be negative.
f(x) = x^5 - 3x^3 + 2x + 4
As x --> -∞ x^5 will be the main factor for f(x) ---> -∞ .
Similarly x^5 will have the greatest influence when x ---> ∞, so f(x) ---> ∞.
