Answers:
- prime number = {2,3,5}
- composite number = {4,6}
- number less than four = {1,2,3}
- number more than or equal to three = {3,4,5,6}
====================================================
Explanation:
The list of all possible outcomes on a single standard die is {1,2,3,4,5,6}. The curly braces indicate set notation.
A prime number is a number where its only factors are 1 and itself. The value 1 is not prime, and it's not composite either.
Something like 3 is prime because its only factors are 1 and 3. Something like 4 is composite because 4 = 2*2. A composite value has factors other than 1 and itself.
Parts (iii) and (iv) are fairly straight forward. You simply list items less than four for part (iii) and you list items that are three or greater for part (iv).
Answer:
55 ≤ x ≤100
Step-by-step explanation:
Given the battery life equation: y = -10x +100 where x is hours driving
As we know that the maximum value of y = 100% when x= 0
<=> y ≤100
They are driving from Dallas to San Antonio which is a 4.5-hour drive.
=> x = 4.5 so we substitute x into the equation, we have:
y = -10*4.5 +100
<=> y = -45 + 100 = 55
Hence, the range of this situation is:
55 ≤ x ≤100
Hope it will find you well.
The answer would be 32 because the parenthesis are just there because its negative and 2 negatives multiplied together make a positive :)
