Step-by-step explanation:
1410+0515= 1925
Answer:
0.04746
Step-by-step explanation:
To answer this one needs to find the area under the standard normal curve to the left of 5 minutes when the mean is 4 minutes and the std. dev. is 0.6 minutes. Either use a table of z-scores or a calculator with probability distribution functions.
In this case I will use my old Texas Instruments TI-83 calculator. I select the normalcdf( function and type in the following arguments: :
normalcdf(-100, 5, 4, 0.6). The result is 0.952. This is the area under the curve to the left of x = 5. But we are interested in finding the probability that a conversation lasts longer than 5 minutes. To find this, subtract 0.952 from 1.000: 0.048. This is the area under the curve to the RIGHT of x = 5.
This 0.048 is closest to the first answer choice: 0.04746.
2 + 3x = 4 + 2x + x^2
x^2 - x + 2 = 0
(x - 0.5)^2 - 0.25 + 2 = 0
(x - 0.5)^2 = -1.75
x - 0.5 = +/- sqrt 1.75 * i
x = 0.5 + 1.32i , 0.5 - 1.32i answer
Answer:
The computer loses 50%, percent of its value each year.
Step-by-step explanation:
See the graph attached.
A computer is sold for a certain price and then its value changes exponentially over time.
It is clear from the graph that at t = 0, the price was $500, then at t = 1 year, the price was $250 and at t = 2 years, the price was $125 and at t= 3 years, the price was $62.5 and so on.
Therefore, the computer loses 50%, percent of its value each year. (Answer)
Answer:
5.4
Explanation:
a²+b²=c²
2²+5²= 4+25
4+25=29
Now we have to square root the 29 which would make the answer 5.4
