Answer:100B + 50M ? 25000
Step-by-step explanation: CZ 75B has a firing pin block which makes for a longer SA trigger pull. CZ 75 has the superior trigger. Aren't the magazines different (and not interchangeable) as well? IIRC, the older 75 mags are not easy to find, and can be expensive.Apr 22, 2011
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)
Answer:
-1/3 sqrt(21)
Step-by-step explanation:
1/3 sqrt(21) - 2/3 sqrt(3) * sqrt(7)
We know sqrt(a) * sqrt(b) = sqrt(ab)
1/3 sqrt(21) - 2/3 sqrt(21)
Factor out sqrt(21)
sqrt(21) (1/3-2/3)
sqrt(21) (-1/3)
-1/3 sqrt(21)
