The amount of time workers spend commuting to their jobs each day in a large metropolitan city has a mean of 70 minutes and a st
Xelga [282]

Answer:

81.85% of the workers spend between 50 and 110 commuting to work

Step-by-step explanation:

We can assume that the distribution is Normal (or approximately Normal) because we know that it is symmetric and mound-shaped.

We call X the time spend from one worker; X has distribution N(μ = 70, σ = 20). In order to make computations, we take W, the standarization of X, whose distribution is N(0,1)

W = \frac{X-μ}{σ} = \frac{X-70}{20}

The values of the cummulative distribution function of the standard normal, which we denote \phi , are tabulated. You can find those values in the attached file.

P(50 < X < 110) = P(\frac{50-70}{20} < \frac{X-70}{20} < \frac{110-70}{20}) = P(-1 < W < 2) = \\\phi(2) - \phi(-1)

Using the symmetry of the Normal density function, we have that \phi(-1) = 1-\phi(1) . Hece,

P(50 < X < 110) = \phi(2) - \phi(-1) = \phi(2) - (1-\phi(1)) = \phi(2) + \phi(1) - 1 =  \\0.9772+0.8413-1 = 0.8185

The probability for a worker to spend that time commuting is 0.8185. We conclude that 81.85% of the workers spend between 50 and 110 commuting to work.

Chris bought six pounds of apples for 10.80. How much would 15 pounds of apples cost at the same price per pound?
love history [14]

Answer: $27

Step-by-step explanation: First we would like to know how much it costs per pound of apples. To find that out simply divide 10.80 by 6 to find the price for one pound. 10.80/6 = $1.80 per pound of apples.

Now, we want to find out how much 15 pounds of apples cost. Simply multiply 1.80 x 15 to find the price of 15 pounds of apples. 1.80 x 15 = $27 for 15 pounds of apples.

9p - 8 + 8 <br> please explain (if you can) :)
11Alexandr11 [23.1K]

Answer:

<h2>9p</h2>

Step-by-step explanation:

9p - 8 + 8

9p - 0

9p

-8 + 8 cancel out.

9p is a variable, and its own term with no like terms. so you leave it alone.

That gives you 9p

Hope that helps!
