Answer:
The probability that exactly three of them are comfortable with delivery by drones is 0.2583.
Step-by-step explanation:
Let <em>X</em> = number of consumers comfortable having drones deliver their purchases.
The probability of the random variable <em>X</em> is, P (X) = <em>p</em> = 0.43.
Then <em>q</em> is, <em>q</em> = 1 - p
A sample of <em>n</em> = 5 consumers are selected.
The random variable <em>X</em> follows a Binomial distribution with parameters <em>n</em> and <em>p</em>.
The pmf of <em>X</em> is:
Compute the value of P (X = 3) as follows:
Thus, the probability that exactly three of them are comfortable with delivery by drones is 0.2583.

Answer:
4 feet on each side.
Step-by-step explanation:
Given :
Width of the wall = 11 feet
Width of the window = 3 feet
Now for the window to be placed in the center of window :
= 4 feet
Therefore, in order to place the window on the center of the wall, 4 feet space must be there on each side of the window.
Answer:
1. 5x+10y=35 x= 5 y= 1
2. 2x+12y=30 x= 3 y= 2
Step-by-step explanation:
1. 5x+10y
10+5=15; 15-10=5; x=5
10/5=2; 2/2=1; y=1
5(5)=25
10(1)= 10
25+10= 35
YAY!
2. 2x+12y
12/2=6; 6/2=3; x=3
12/6=2; y=2
2(3)=6
12(2)=24
24+6= 30
YAY!
