We see that the slope intercept is y = 8x - 20. So if we substitute x with 2, because x represents the amount of necklaces sold and we are analyzing her net profit after selling 2 necklaces, that gives us y = 8(2) - 20. Which simplifies to y = -4. So by the time Jocelyn sells 2 necklaces, her net profit will be at -4.
Answer:
25 because the 8 values must times with 7 and will get 56. when the ninth value added , let the ninth value as y , 56+y , the new mean is 9 . so it will be like this , 56+y over 9 times with 9
Bag weight 1.8 kg
Golf ball weight: 45g
1 kg = 1000g
Total bag weight in grams = 1.8 x 1000 = 1800g
total bag weight / golf ball weight = total balls in bag
1800 / 45 = 40
Total balls in bag = 40.
