Answer:
the answer is 240
Step-by-step explanation:
If 4% are defective, then out of a batch of 250, the number of defective is
4% x 250 = 4/100 x 250 = 10 defective
So, the number of not defective is 250 - 10 = 240 good!
Answer: -3 ≤ x ≤ -1
Step-by-step explanation:
1 ≤ 3 - 4x ≤ 9
1 + 3 ≤ - 4x ≤ 9 + 3; Add 3 on all sides
4 ≤ -4x ≤ 12
1 ≤ -x ≤ 3; Divide 4 on all sides
-1 ≥ x ≥ -3; Multiply -1 on all sides(FYI: When multiplying or dividing negative numbers in inequalities, make sure to reverse the signs as well)
