there are 10 numbers you want either a 4 or 7 ( 2 numbers)
so probability is 2/10 which reduces to 1/5
Answer:
1) Option 3
2) Option 1
3) Option 2
Step-by-step explanation:
To find : Match each number in scientific notation with the number written in standard form and in a step by step process.
Solution :
From scientific to standard we expand the power of 10.
1) 
Remove decimal and open the power,
Therefore, 
Match with Option 3.
2) 
Remove decimal and open the power,
Therefore, 
Match with Option 1.
3) 
Remove decimal and open the power,
Therefore, 
Match with Option 2.
Answer:
48
Step-by-step explanation:
4/6 = 2/3
2/3 times 72 = 48
Lets work backwards, he had $5 after it all, and spent $1.25 on a snack, so we add that to the remainder, which is $6.25. then he spent half of that on whatever stuff he likes, so add $6.25 and $6.25, which is $12.50
So i'm assuming 33^a is saying any number that is a square of 33 inside of 1,313 so first, to find how many even numbers divide 1,313 by two to get 656.5 so if I am not mistaken 656 numbers in 1,313 will be even. Now find all squares of 33 that don't pass 1,313 which is 33 itself and 1,089 because 33^3 is 35,937 so add 2 to 656 to get 668. so the probability is 658/1,313 i believe.
