Answer: They will drive 224 miles
Explanation: We know that they can drive 112 miles on 4 gallons
We set that up as 112/4 (miles per gallon)
8 is 4 twice, in other words, 4 times 2
So now we can see that 112 ?
------ -----
4 8
You do what you did on the bottom (times 2 to get 8) to the top (times 2 to get 224)
Hope this helps!
The cell body, also called the soma, is the spherical part of the neuron that contains the nucleus. The cell body connects to the dendrites, which bring information to the neuron, and the axon, which sends information to other neurons.
Can you rephrase the question? :)
Answer:
The random variable W is Normal, with a mean of 48 ounces and a standard deviation of four ounces.
Explanation:
By their properties, mean of μ(4x) = 4 * μ(x) and a standard deviation of σ(4x) = 4 * σ(x).
So the distribution of weight of four loaves of bread, W, still follows a Normal Distribution with a mean of 4*12 = 48 ounces and a standard deviation of 4*1 = 4 ounces.
