Scientific notation is where people make ginormous numbers to a number inbeween ten and one. Very small numbers to, here are some examples.
6,000= 6 x 10^3
.0006= 6 x 10^-4. Hope this helped!
Answer:
36000 different ways
Step-by-step explanation:
If we have 5 boys and 3 girls, the total number of people we have will be 5+3 = 8 people. If there are no restrictions, this 8 people can be arranged in 8! different ways.
8! = 8*7*6*5*4*3*2*1
8! = 40,320 ways.
If 3 of the girls are to sit together, then we will take the girls as an entity. The total number of people if the girls are treated as one will be 5 boys and a girl which is 6. They can all be arranged in 6! ways but also note that the 3 girls can be rearranged among themselves in 3! ways. The total number of arrangement if the 3 girls are to sit together will be 6!*3!.
6!*3! = 6*5*4*3*2*3*2
6!*3! = 4320 different ways
The number of different ways if no girls are to seat together = 8!- (6!*3!)
= 40,320 - 4,320
= 36000 different ways
I think the answer is c because Bill is surveying every fourth person who enters the mall, which would be the population surveyed. Hope I helped! (Let me know if I got it wrong)
Answer:
1.33333333333
, simplified to 1.3

Our equation is 2 multiplied by 2 over 3.
Fractions mean division.
So, let's multiply 2 by 2/3.
We get 1.33333333333
That's too long! What can we simplify it to?

Answer:
10 hours
Step-by-step explanation:
Given:
Average speed of submarine = 10 mph
Speed of carrier in the opposite direction = 20 mph
Distance between the submarine and carrier = 300 mi
To find:
The time taken so that the distance between them is 300 mi ?
Solution:
The relative speed when they are traveling in opposite direction = 10+20 = 30 mph
Formula:
So, the answer is <em>10 hours</em>.
