Answer:
26in^2
Step-by-step explanation:
5 time 4 is 20in^2. plus 2 times 3 is 6in^2.
add 20 and 6 then you get 26in^2.
1 true and false question = 1 / 2 chances
2 multiple choice question = 2/8
1/2 + 2/8 =
4/8 + 2/8 = 6/8.
6/8 = 3/4
you have a 75% chance of getting all 3 answers correct and getting a 100% on the quiz
hope this helps :D
Answer:
(2,2) is the solution of the given lines.
Step-by-step explanation:
Given that,
y = x ..(1)
y = 3x-4 ...(2)
We need to find the coordinates of the point of intersection.
From equation (1) and (2).
x=3x-4
4 = 3x-x
4 = 2x
x = 2
Also,
y = 2
<h3>Hence, the coordinates of the point of intersection is (2,2).</h3>
Answer:
The probability of getting two consumers comfortable with drones is 0.3424.
Step-by-step explanation:
The probability that a consumer is comfortable having drones deliver their purchases is, <em>p</em> = 0.43.
A random sample of <em>n</em> = 5 consumers are selected, and exactly <em>x</em> = 2 of them are comfortable with the drones.
To compute the probability of getting two consumers comfortable with drones followed by three consumers not comfortable, we will use the Binomial distribution instead of the multiplication rule to find the probability.
This is because in this case we need to compute the number of possible combinations of two consumers who are comfortable with drones.
So, <em>X</em> = number of consumers comfortable with drones, follows a Binomial distribution with parameters <em>n</em> = 5 and <em>p</em> = 0.43.
Compute the probability of getting two consumers comfortable with drones as follows:
![P(X=x)={5\choose x}\ 0.43^{x}\ (1-0.43)^{5-x};\ x=0,1,2,3...](https://tex.z-dn.net/?f=P%28X%3Dx%29%3D%7B5%5Cchoose%20x%7D%5C%200.43%5E%7Bx%7D%5C%20%281-0.43%29%5E%7B5-x%7D%3B%5C%20x%3D0%2C1%2C2%2C3...)
![P(X=2)={5\choose 2}\ 0.43^{2}\ (1-0.43)^{5-2}](https://tex.z-dn.net/?f=P%28X%3D2%29%3D%7B5%5Cchoose%202%7D%5C%200.43%5E%7B2%7D%5C%20%281-0.43%29%5E%7B5-2%7D)
![=10\times 0.1849\times 0.185193\\=0.342421857\\\approx 0.3424](https://tex.z-dn.net/?f=%3D10%5Ctimes%200.1849%5Ctimes%200.185193%5C%5C%3D0.342421857%5C%5C%5Capprox%200.3424)
Thus, the probability of getting two consumers comfortable with drones is 0.3424.
