Answer:
80% of the students would vote for Tammy
Step-by-step explanation:
Since a Kimberly took a sample of 30 students from the school and it was found that 24 students said they would vote for Tammy. To determine Kimberly's best estimate of the number of students in the school who would vote for Tammy, we divide the number of students that said they would vote for tammy by the total number of student sample.
number of students who would vote for Tammy = students who said would vote for sammy / number of sample = 24 / 30 = 4/5 = 80%

25% of students like cheesecake
Hello from MrBillDoesMath!
Answer:
One solution (z = -1)
Discussion:
-2(z+3)-z=-z-4(z+2) =>
-2z -6 -z = -z -4z - 8 =>
-3z -6 = -5z -8 => add 6 to both sides
-2z = -5z -2 => add 5z to both sides
3z = -5z +5z -3 =>
3z = -3 =>
z = -1
Thank you,
MrB
