Answer:
12
Step-by-step explanation:
Answer:
15 students (30% of the students in class) scores a 95 on a quiz.
Therefore the total number of students (100% of the students) in class is:
N = 15 x 100/30 = 50 (students)
(This calculation is inferred from a ratio that 15/N = 30/100).
Denote the number of students who scored a 95 on a quiz is a, the total number of students in class is b.
Then the equation that related a and b is:
b = (100/30) x a

Relative frequency : total number of diamonds / total number of cards drawn = 11/40=0.3
The answer is 30% : C
Answer:
x≥11
Step-by-step explanation:
2(4+x)+2(3x) ≥96
as at least means either greater than or equal to
now simplify as 2 multiplies 4+x
8+2x+6x ≥96
8+8x≥96take 8 on other side
8x≥96-8
8x≥88
x≥88/8
x≥11
