Answer: Our required probability is 0.167.
Step-by-step explanation:
Since we have given that
n = 15
Probability of success p = 80% = 0.8
Probability of failure q = 20% = 0.2
We need to find the probability that at least fourteen will work.
So, by Binomial distribution, we get that

Hence, our required probability is 0.167.
Hey Jackson!
-4x + 3y = 3
y = 2x + 1
Ok so what we need to do is solving y= 2x + 1 for y.
So let's start by using the substitution method :)
Substitute 2x + 1 for y in -4x + 3y = 3
-4x+ 3y = 3
-4x + 3(2x + 1) = 3
-4x + (3)(2x) + (3)(1) = 3
-4x + 6x + 3 = 3
2x + 3 = 3
Subtract 3 on both sides
2x + 3 - 3 = 3 - 3
2x = 0
x = 0/2
x = 0
So now since we find the number for x, we gonna use it to help us find the value for y.
To find y, we need to substitute 0 for x in y = 2x + 1
y = 2x + 1
y = 2(0) + 1
y = 0 + 1
y = 1
Thus,
The answer is: y = 1 and x = 0
How to graph?
You need to go on the thing where they put the numbers. y is located on top which has the positive numbers. So when you get there, make a line that comes from the top right side all the way to the bottom left sides. Remember that y = 1 so the line must pass through 1
I am not good with explanation. So I'll leave the graph down below then you'll see what I am talking about :)
Let me know if you have any questions. As always, it is my pleasure to help students like you!
-4 is the rate of change otherwise known as the slope
Answer:
Degree of elevation
Step-by-step explanation:
It tells you the climb at a specific angle. For instance, if you climb 5 feet per every 1 foot of travel, you can create a triangle that has two legs and a hypotenuse. You can then use trigonometric functions to come at the conclusion that the degree of inclination is 78 degrees.

Answer:
225 mL
Step-by-step explanation:
The amount Mariana drank was ...
(4.5 mL/s)×(17 s) = 76.5 mL
The original quantity is that amount added to the amount remaining:
original amount = amount drunk + amount remaining
= 76.5 mL +148.5 mL
original amount = 225 mL
