The answer is "c. continuous probability distribution."
"Continuous" means it is a subset of the real numbers set: it can take any value in a specified range. For example, if you break at random a stick with a given length of 12 cm, and then measure the shortest piece, you can get any value in the range (0 cm, 6 cm). This is a continuous random variable.
A random variable is said to be "discrete" if it can only take values from a finite (or countably infinite) set. For example, if you roll a dice, you can get only 1, 2, ..., 6. But you cannot get any vaue in the range [1, 6], because the value must be an integer (e.g., you cannot get the vaue 2.5). This is a discrete random variable.
A somewhat technical explanation:
- A random variable is a mapping from a event space to a number set: it associates a number (a value of the variable) with every event.
- The random variable is said to be continuous if it maps events to numbers from a subset of the set of real numbers.
- The probability distributions corresponding to continuous random variables are called continuous probability distributions.
Answer:
In the case of a Type I error, the null hypothesis would be wrongly rejected and the school district will conclude that the new technology is effective when it is not.
They will start to pay for the software when in fact it does not improve Algebra 1 skills.
Step-by-step explanation:
A Type I error happens when a true null hypothesis is rejected.
The probability of a Type I error is equal to the significance level, as it is the probabilty of getting an sample result with low probability but only due to chance, as the null hypothesis is in fact true.
In this scenario, the null hypothesis would represent the claim that the new technology does not make significant improvement.
In the case of a Type I error, this null hypothesis would be wrongly rejected and the school district will conclude that the new technology is effective when it is not.
They will start to pay for the software when in fact it does not improve Algebra 1 skills.
Answer:
The tank can hold 18.84 cubic feet
Step-by-step explanation:
Given
Shape: Cylinder
-- Diameter
-- Height
Required
Determine the volume
First, calculate the radius (r)
The volume (V) of the tank is:
Substitute values for r and h
<em>Hence, the tank can hold 18.84 cubic feet</em>
Depends on the beginning of the question. if the first one was NOT replaced your answer is 54/1570 BUT if the first one WAS replaced then the answer is 55/1570.
