Answer:
.22
Step-by-step explanation:
The number of times a 3 was rolled is 44 out of 200
The experimental probability is 44/200 = .22
Answer:
Step-by-step explanation:
a=0 and b=20 in the uniform density function
∴ the mean μ===10 and
the variance ==.
The standard deviation is the square root of the variance, so
Having determined the mean and standard deviation of the uniform distribution, we can conclude that follows a normal distribution with and .
The normal probability distribution is:
So, substituting and
Having approximated sum , we move on to the standardized sum , which is the same as only with μ=0 and σ=1. This means the probability distribution is the standard normal distribution, which is:
Answer:
the graph should be of the line y=5x
Step-by-step explanation:
the x axis should be labeled hours and the y axis should be labeled amount earned or dollars
the coordinates on the graph should be
(1,5) (2,10) (3,15) (4,20) (5,25) (6,30)
I cannot see the answer choices but I hope this information helps you answer the question
To add the two expressions, we can write it as:
4.6x-3 + (-5.3x+9)
We can distribute the plus sign (which means just drop the parenthesis in this case):
4.6x-3-5.3x+9
Now, we can simplify by combining like terms:
-0.7x+6
Answer: y=4x
So on this question you would plug in just one pair of x and y into an equation; just some trial and error
Explanation:
Let’s say you plug in -8 for your y and -2 for your x. Your equation would look like this:
-8= 4(-2)
Then solve
-8= 4(-2)
-8= -8
Once each sides of the equation are equal, that’s when you know that’s the right answer
