Answer:
Step-by-step explanation:
500m = profit on mid-sized cars
750s = profit on SUVs
500m + 750s = total profit
You have two conditions:
(1) 500m + 750s ≥ 3500
(2) m ≥ 2s
Let s = 2
Check condition (1)
500m + 750 × 2 ≥ 3500
500m + 1500 ≥ 3500
500m ≥ 2000
m ≥ 4
Check condition (2)
(2) m ≥ 2 × 2
m ≥ 4
Check:
500 × 4 + 750 × 2 ≥ 3500 4 ≥ 2 × 2
2000 + 1500 ≥ 3500 4 ≥ 4
3500 ≥ 3500
OK.
Answer:
ok...............no
Step-by-step explanation:
Area = 1/2 b * h
h = b - 9
b = b
Area = 56cm^2
Area = 1/2 (b - 9) * b
56 = 1/2 (b^2 -9b)
112 = b^2 - 9b
b^2 - 9b - 112 = 0
b = 16 and therefore the height is
h = 26 - 9 = 7
Check
Area = 1/2 * 16 * 7
Area = 8 *7
Area = 56 which checks.
Question;
In the next year, an economist in a particular nation believes that exports will have a mean of 295 and a standard deviation of 12 (in millions of dollars). In addition, he believes that imports will have a mean of 70 and a standard deviation of 14 (in millions of dollars). Finally, he believes that the correlation between imports and exports will be -0.63. Define the trade balance as exports minus imports. Find the mean and the standard deviation of the trade balance (in millions of dollars) ROUND YOUR ANSWERS TO TWO DECIMAL PLACES
Answer:
Mean = mean exports - mean imports = 295 - 70 = 225.00
Standard deviation = 12 - 14 = -2( in million dollars)
1. Exponential
2000 times 2= 4000 (60)
4000 times 2= 8000 (120)
8000 times 2= 16000 (180)
16000 times 2= 32000 (240)
2. pull a 2x out of everything
answer is b
