Answer:
<u>Option A. 0,1,2,3,4</u>
Step-by-step explanation:
The rest of the question is the results of survey, the results is as following:
Rock 50%
Country 30%
Hiphop 10%
Classical 10%
<u>Solution:</u>
Caleb signs the numbers zero through nine to the music category and uses a random number generator on his calculator.
So, the number of digits from 0 to 9 = 10
Since 50% represents the number of students interested in Rock, So, he want to have 50% of the digits to represent Rock.
50% of 10 numbers is 5 numbers.
So, The option which has 5 digits is option A. 0,1,2,3,4

(Z-4)/12
Answer:
1. d 2. a 3. d 4. a 5. a
Step-by-step explanation:
For 1, d is negative because, if there an even number of negatives, the answer will be positive. a. would have been correct, but you multiply that one by 0. 0 is not negative, so the answer has to be d.
2. is -21. You can multiply 3 times seven then make it negative, or simply add -7 together 3 times.
3. is d because the two negatives cancel each other out. Even numbers of negatives cancel each other out. therefore, 17 times 6 is 102.
4. -120 is the answer because there are 3 negatives. That is an odd number, so we know our answer is negative. -5 times -3 is 15, and 15 times -8 is -120.
5. is a because -1 times 4 is -4, then -4 times -9 is 36. 36 times -3 is then -108.
A and D are correct. To understand this, you need to know that this scenario gives us a total (2 1/2 cups) and a part (1/4). When you have these 2 pieces of information you have either a division problem with a total divided into parts (choice D) or you have one part and a totol shown as a multiplication problem (choice A).
