Answer:
27 small cubes
Step-by-step explanation:
Given that,
The volume of the large cube is 
The volume of small cube is 
We need to find how many small cubes make up the large cube. Let there are n small cubes. So, it can be calculated as follows :
So, there are 27 small cubes that make up of the large cube.
Answer:
There is some inforrmation that is missing in this question. It should read:
A container holds 50 electronic components, of which 10 are defective. If 6 components are drawn at random from the container, the probability that at least 4 are not defective is . If 8 components are drawn at random from the container, the probability that exactly 3 of them are defective is .
Answers
Part 1. 0.02
Part 2. 0.0375
Explanation
The probability is a chance of an event happening. It is calculated as;
probability = (Number of favourable outcome)/(Number of available outcome)
Part 1
6 are chosen at random. If 4 are not defective, then 2 are defective.
P(at least 4 are not defective) = 4/40 × 2/10
= 1/10 ×1/5
= 1/50
= 0.02
Part 2
8 are chosen at random. If 3 are defective, the 5 are not defective.
P(3 are defective) = 3/40 × 5/10
= 15/400
= 3/80
= 0.0375
Step-by-step explanation:
If two non-vertical lines are perpendicular, then their slopes are opposite reciprocals giving you -1.
:) Hope this helps.
Distance between Los Angeles and San Francisco = 385 miles
So , if we have to locate 385 miles on the map taking the scale
1 inches = 15 miles
1 miles = 
inches
so, 385 miles = 
→→385 miles = 25.67 (approx)
Option (B) is correct.
