Answer:
0.5r
Step-by-step explanation:
If Jerry completed his journey in half the duration that Macy did, it implies Macy's time was twice as lengthy. Assuming Jerry’s speed is r, Macy’s speed would therefore be 0.5r, indicating she travels at half Jerry's pace and takes twice as long to cover the distance.
Answer:

Step-by-step explanation:
A polynomial is in its standard form when arranged in descending order based on the variable involved.
Looking at the provided polynomial

- s is presented in descending powers
- r is in ascending order
Thus, the first term of the polynomial should meet these criteria:
- Power of r is less than 2
- Power of s is greater than 4.
The following meets these requirements:

Answer:
The correct choice is the third one.
Step-by-step explanation:
Answer:

Step-by-step explanation:
Assuming a fair die is rolled.
- The sample space comprises 1, 2, 3, 4, 5, 6, with all results being equally probable.
Let X represent the collection of all outcomes. Let A represent a specific outcome.
<pThus, the probability of event A occurring is:

Considering that the set of all possible outcomes for a singular die roll is:

Notably,

Here,
since 8 is not included in the sample space. Therefore, rolling an 8 is impossible within the defined outcomes.
<pThis leads to the conclusion that the probability is zero.
In other terms,


<pAs a result,
