Answer:
The probability density function of <em>X</em> is:

Step-by-step explanation:
A continuous Uniform distribution is the probability distribution of a random outcome of an experiment that lies with certain specific bounds.
Consider that random variable <em>X</em> follows a continuous Uniform distribution and the value of <em>X</em> lies between <em>a</em> and <em>b</em>.
The probability density function of the random variable <em>X</em> is:

Now, in this case it is provided that the amount of salad taken is uniformly distributed between 5 ounces and 15 ounces.
The random variable <em>X</em> is defined as:
<em>Χ</em> = Salad plate filling weight.
The probability density function of the salad plate filling weight is:

A. False. There are 8 texts for every 5 calls made.
B. False. The ratio of texts to calls is 8:5, instead of 5:8
C. True. You just write the numbers 8 and 5 separated with a colon.
D. True. This is the same as saying "forever 8 texts, there were 5 calls"

These statistics are impossible: all students who ride bike and use crossing guard ride a bike, so the proportion of students who ride a bike and use the crossing guard must be less than or equal to the proportion of students who ride a bike. This is not true in the given stats; 0.12 > 0.1
