Answer:
6%
Step-by-step explanation:
The probability of picking a maths student = 21% = 21/100
The probability of picking a science student = 15% = 15/100 = 3/20
The probability of picking in both = 6/100 = 3/50
The probability that the student is in maths or science = 21/100 - 15/100 = 6/100 = 6%.
10/(10-6)=10/4.
(10*9*8*7*6*5*4*3*2*1)/(4*3*2*1)
Numbers that are in the numerator and denominator are cancelled out
10*9*8*7*6*5=151200 codes
* means multiply if you didn't know
The correct answer is D

Answer:
Step-by-step explanation:
There are 47 acres and the farmer is planting 140,000 per acre.
You got to times 140,000 by 47 but you can multiply 14 by 47 instead and place the zero later.
So take 10 times 47 and that is 470
Then take 4 times 47 and that is 188
Add 470 and 188 and you get 658
Take 658 a place the four zeros and you get 6,580,000 seed
