Answer:
1.125
Step-by-step explanation:
1. Area=2.7*1.5;
2. Area=h*3.6;
3. 2.7*1.5=3.6*h; ⇒ h=2.7*1.5/3.6=1.125 units
Option A is correct answer
V=Bh so you would do 25.4 x 17 which equals 431.8
Answer:
x= 5/2, 1/3
Step-by-step explanation:
(2x – 5)(3x – 1) = 0
(2x – 5) = 5/2
(3x-1) = 1/3

Answer:
a) The mean of the probability distribution = 0.6
b) The variance of the probability distribution = 0.3
c) The standard deviation of the probability distribution = 0.5
Step-by-step explanation:
a) Data and Calculations:
number of dogs per household in a small town
Dogs Probability Expected Mean Diff Mean Diff.
Value Squared
0 0.650 0 -0.569 0.32376
1 0.216 0.216 -0.353 0.12461
2 0.087 0.174 -0.395 0.15603
3 0.026 0.078 -0.491 0.24108
4 0.014 0.056 -0.513 0.26317
5 0.009 0.045 -0.524 0.27458
The mean = 0.569 (Sum of expected value)
Variance = mean of squared differences = 0.27665 (1.38323/5)
Standard deviation = square root of variance = 0.526 = 0.5
