to find the distance between 2 points we should apply the formula
call point q as point 1 for reference in the formula and p as point 2
replace the coordinates in the formula
simplify the equation
the distance between the 2 points is 5 units
Answer:
5.25x - 6
Step-by-step explanation:
<u>1.75x</u> -2 + <u>1.75x</u> -2 + <u>1.75x </u>-2
5.25x <u>- 2 - 2 - 2</u>
5.25x - 6
0.0038 is the probability that the code is 9Z.
<u>Step-by-step explanation:</u>
Here we have , A code consists of a digit chosen from 0 to 9 followed by a letter of the alphabet. We need to find What is the probability that the code is 9Z . Let's find out:
A code consists of a digit between 0-9 , i.e. there are 10 choices . And followed by a letter i.e. from A-Z having 26 choices ! So combinations possible are :
0{A-Z}=26
1{A-Z} = 26
2{A-Z} = 26
3{ A-Z}=26
.......
9{A-Z}=26 or ,
⇒ 10(26)
⇒
Now , 9Z is one combination ! So , probability :
⇒
⇒
Therefore , 0.0038 is the probability that the code is 9Z.
Answer:
13/17
Step-by-step explanation:
Since we have 30 total students and 17 girls you would subtract 30-17 to get 13 and that would be boys, so the ration from boys to girls would be 13/17.
