The mode is 3. The median is 3. The mean is 6.45 and rounded to the nearest tenth is 6.5. So the mean is 6.5.
Answer:
-7< x < 6
Step-by-step explanation:
|4x + 2| < 26
The absolute value has a positive and a negative. Remember to flip the inequality when taking the negative
4x+2 < 26 and 4x+2 > -26
Subtract 2 from each side
4x+2-2 < 26 -2 and 4x+2 > -26-2
4x < 24 and 4x > -28
Divide by 4
4x/4 < 24 4x/4 >-28/4
x <6 and x> -7
-7< x < 6
Before I distribute, I solve the inside first:
2/3[8(3)^2+6]
2/3[8(9)+6]
2/3[72+6]
2/3[78]
2*26= 52 is the answer
another way:
2/3[8(3)^2+6]
2/3[8(9)+6]
2/3[72+6]
(2/3)*72+(2/3)*6
2*24+2*2
48+4= 52
