Answer:
0.7455
Step-by-step explanation:
First, we note that there are C
= 220 ways of selecting the defective items.
The probability that the inspector will have to test at least 9 widgets would be 1 minus the probability that the inspector will have to test 8 or less widgets.
This is 1 - P(8 or less widgets have to be checked)
1 - 
= 1 - 56/220
= 1 - 0.2545
= 0.7455
From what I think of this question, i think of 9x37 and 8x37 OR 9/37 and 8/37. either way
8x37=296
9x37=333
9/37=0.2432
8/37=0.2162
Answer:
12
Step-by-step explanation:
6 * 5 is 30 6*2 is 12
Total of area of faces so (20*6+20*4+4*6)*2=448 cm ^2
3,540 grams of ash
If its density is 2.75 g/cc and
density = mass / volume then its volume is
volume = mass / density
volume = 3,540 g / 2.75 g / cc
volume =

<span>
1287.272727 cc
So, rounded it is 1,287.3 cubic centimeters but to keep the same number of significant figures, the volume is
