30% percent is what they marked up
Answer:
0.03593
Step-by-step explanation:
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score = 17,340
μ is the population mean = 15,000
σ is the population standard deviation = 1300
z score:
z = 17340 - 15000/1300
z =1.8
Probability value from Z-Table:
P(x<17340) = 0.96407
P(x >17340) = 1 - P(x<17340)
= 1 - 0.96407
= 0.03593
The probability that the life span of the monitor will be more than 17,340 hours is 0.03593

"Cavalieri's Principle. If, in two solids of equal altitude, the sections made by planes parallel to and at the same distance from their respective bases are always equal, then the volumes of the two solids are equal "(Kern and Bland 1948)
both same height both equal in all ways
Answer:
Eli is driving 14.3736 km above the speed limit.
Step-by-step explanation:
First we convert:
1 mile = 1.60934 Km
Next we multiply:
1.60934 * 40 = 64.3736
Lastly we subtract
64.3736 - 50 = 14.3736
So, the answer is 14.3736
Hope this helps! :)
