Answer:
27/64
Step-by-step explanation:
(7×16)+(5×64)64×16
=112+3201/024
=432/1024
Simplifying 432/1024, the answer is
=27/64
The answer to this question is 2.
Why not look up "standard deviation" yourself, to be sure? But yes, the std. dev. is the sqrt of the variance.
Answer:
y = mx + b
-1 = 2/5(-3) + b
-1 = -6/5+b
-1 + 6/5 = -6/5 + 6/5 + b
1/5 = b
y = 2/5x + 1/5
Step-by-step explanation:
- write down the slope-intercept form formula
- identify your x and y of the point
- replace x and y by the point
- multiply m and x
- do addition to get b
- write down the equation by replacing m and b with their values
Assuming the railroad network is properly constructed it would allow for the rapid transportation of large quantities of materials and troops all throughout the nation.
In the event of damage, having enough routes allows rail traffic to be rerouted around damaged rail lines. The ability to get to a location via different routes makes it harder for an enemy to cripple the rail network.
If there is only one line and it gets destroyed, all of the traffic comes to a halt.
