The problem is not shown clearly therefore i am not sure if my answer will be correct, but, this inequality is already solved. all this means is that y is more than or equal to 4.5 (meaning that y can be 4.5, 5, 6, 7, 8 and so own but never a number less than 4.5), the "I I" only mean that y will never be a negative.
Answer:
A. 51.15.
Step-by-step explanation:
Number of ears, n = 20
Samples = 49, 52, 48, 52, 54, 51, 53, 53, 53, 51, 52, 52, 50, 51, 51, 53, 52, 46, 48, 52
Average = summation of sample/n
= (49 + 52 + 48 + 52 + 54 + 51 + 53 + 53 + 53 + 51 + 52 + 52 + 50 + 51 + 51 + 53 + 52 + 46 + 48 + 52)/20
= 1023/20
= 51.15
R=red
blue=b
g=green
r+g+b=33
r=4g
b=g/2
we must convert to a common unit which could be the smallest unit so we must convert to blue
b=g/2 or g=2b
r=4g
r=4(2b)
r=8b
r=8b
g=2b
b=b
r+g+b=33=8b+2b+b=11b
11b=33
divide both sides by 11
b=3
g=2b
g=2(3)
g=6
r=8b
r=8(3)
r=24
r=24
g=6
b=3
I believe your answer is A for this question
