Answer:
66 pieces of candy.
Step-by-step explanation:
First I set up the equation: (c/6)-4 = 7
c represents the candy she started with.
6 represent when she split the candy
4 is the number of pieces she has eaten
7 is the number of pieces she has left
after setting up the equation, you want to add four to the other side to get 11
c/6 = 7+4 --> c/6 = 11
Then you want to multiply by 6 to get ride of the fraction to get a total of 66 pieces of candy.
c = 11 x 6 --> c = 66

THE ANSWER IS EQUILATERAL BECAUSE THEY ALL HAVE EQUAL SIDES
Answer:
Question 1:
Here total number of students GPA is given = 50
Number of people who have GPA more than 3.69 = 5
Therefore,
Pr(That a student has GPA more than 3.69) = 5/50 = 0.1
Here X ~ NORMAL (3.12, 0.4)
so Pr(X > 3.69) = Pr(X > 3.69 ; 3.12 ; 0.4)
Z = (3.69 - 3.12)/ 0.4 = 1.425
Pr(X > 3.69) = Pr(X > 3.69 ; 3.12 ; 0.4) = 1 - Pr(Z < 1.425) = 1 - 0.9229 = 0.0771
Question 2
Here GPA would be above 95.54th percentile
so as per Z table relative to that percentile is = 1.70
so Z = (X - 3.12)/ 0.4 = 1.70
X = 3.12 + 0.4 * 1.70 = 3.80
so any person with GPA above or equal to 3.80 is eligible for that.
Yes this is correct. if you do distribution and multiply 2 times x it's 2x. you then multiply 2 times 6 and this equals 12. add twelve and 8 and this equals 20. the answer 2x+20 is correct
