Wewaii [24]

$n=5,x=3,p=0.46,q=0.54$ .

<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 :

⇒ $p=0.46$

And , probability of failure :

⇒ $q=1-p =1-0.46$

⇒ $q=0.54$

Now , n = Number of people randomly selected = 5

x = Number of people exactly comfortable = 3

Therefore , $n=5,x=3,p=0.46,q=0.54$ .

Evangeline is buying a circular shaped rug that covers 78.5 square feet. How far is it from one edge of the rug to the other?

Korolek [52]

Hey there!

In this scenario, we are given the area of the rug. It is asking for the diameter, the distance across the rug. The area is the radius (half of diameter) squared times pi (we will use 3.14).

First, we need to undo the area and find the radius.

78.5/3.14=25

√25=5

Since the diameter is twice the radius, we multiply or radius by two.

5*2=10

Therefore, our edge is 10 feet from one edge to the other.

I hope this helps!
