Answer:
The probability of assembling the product between 7 to 9 minutes is 0.50.
Step-by-step explanation:
Let <em>X</em> = assembling time for a product.
Since the random variable is defined for time interval the variable <em>X</em> is continuously distributed.
It is provided that the random variable <em>X</em> is Uniformly distributed with parameters <em>a</em> = 6 minutes and <em>b</em> = 10 minutes.
The probability density function of a continuous Uniform distribution is:
Compute the probability of assembling the product between 7 to 9 minutes as follows:
![=\frac{1}{4}\times [x]^{9}_{7}\\](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%7D%7B4%7D%5Ctimes%20%5Bx%5D%5E%7B9%7D_%7B7%7D%5C%5C)
Thus, the probability of assembling the product between 7 to 9 minutes is 0.50.
The amount of energy it takes to run a race is most likely to be a function of the; D: Length of the Race
<h3>How to find amount of energy?</h3>
We want to basically find the factor that influences the amount of energy expended by a sprinter.
Now, formula for potential energy is;
P = mgd
where;
m is mass
g is acceleration due to gravity
d is distance covered
Now, the only option that falls into the input that affects energy expended is the distance covered. This is true because the more the distance covered, the higher the energy expended.

The answer is “B” because if you do the work correctly that will be your outcome
To find the experimental probability, you will add the outcomes that resulted in even number and make that a ratio to the total number of outcomes.
<u>(12 + 14 + 18)</u>
(13 + 12 + 12 +14 + 11 + 18)
44/80 = 0.55
0.55 = 55%
The answer is choice D.
Answer:
8 shelves
Step-by-step explanation:
As 28 multiple by 2 is 224 and 28*9 is 252 so she will have 8 full shelves
