Two answers are possible.
One is with the repetition of digits.
The other is without repetition of digits.
ANSWER 1: With Repetition
Numbers: 1,2,4,5,7,8
There are 4 digits __ __ __ __
1st digit can be filled by any of the 6 numbers.
Similarly 2nd, 3rd and 4th digits.
Hence each digit will have 6 possibilities.
Therefore no.of 4 digit numbers that can be formed are 6 x 6 x 6 x 6 = 1296
ANSWER 2: Without Repetition
4 digits __ __ __ __
Now the first digit can be filled by any of the six numbers. Therefore there are 6 possibilities
The second digit will have only 5 possibilities as one of the numbers gets used up by the 1st digit.
Similarly the 3rd and 4th digits will have 4 and 3 possibilities respectively.
Therefore no.of 4 digit numbers that can be formed are 6 x 5 x 4 x 3 = 360
Assuming the typewriter-looking words are the line names...
1. Line R
2. Line Q (Or R, but it is most likely Q)
3. Points E and F

Joni should have multiplied by 1,000.
Step-by-step explanation:
Mass of the box = 67 decagrams
1 decagram = 1000 centigrams
So, 67 decagrams = 67 x 1000 centigrams
= 67000 centigrams
Joni should have multiplied by 1,000.
The equation to find the slope of a line is "y2 - y1 / x2 - x1"
Our second y coordinate is 5 and our first y coordinate is 2.
5 - 2 = 3.
Our second x coordinate is -7, and our first x coordinate is 12.
-7 - 12 = -19.
We now have 3 / -19
3 / -19 = ~-0.158
Therefore, the slope of the line is ~-0.158
Answer:
2 hrs and 21 mins I think
Step-by-step explanation:
I subtracted 328-147 and got 181 and since their is 60 mins in one hr I made it another hour and after I subtracted 81-60 and got 21 minutes. 2 hrs and 21 mins. Hope this makes sense.
