(-4)^-6*(-4)^7 = (-4)^1 = -4
answer a. -4
The mean proportion is p = 36/120 = 0.3.
The standard deviation of the proportion will be sqrt(p*(1-p)/n) = sqrt(0.3*0.7/120) = 0.0418. We multiply this by the z-score of 1.645 to get a deviation of 0.0688.
Therefore, the confidence interval is (0.3 - 0.0688, 0.3 + 0.0688), which is
(0.2312, 0.3688).
Solve for y and then graph it on a graphing calculator or since it doesn’t have a exponent you know it’s just a line because it would be the like y=4 which is a horizontal line at 4
Answer:
Therefore, the exact value of Tan 60 degrees is √3. We can also derive the values of tan 0°, 30°, 45°, 90°, 180°, 270° and 360° in the same way
Answer:
150 lb
Step-by-step explanation:
138lb/23 gal = x/25 gal
cross multiply and solve for x
23x = 138·25
x = 3450/23
x = 150 lb
