Yes all the points lay in the line.
Insert the x coordinate into x giving you your y
Answer:
x=5
Step-by-step explanation:
Alright you will need to use PEMDAS for this
- Parenthesis
- Exponent
- Multiplication
- Division
- Addition
- Subtraction ( Take note of this )
Step 1
9(3x – 16) + 15 = 6x – 24 You will remove parenthesis here
27x-129=6x-24
Step 2
Then subtract 6x,
27x-129=6x-24
21x-129=-24
Step 3
Then you add 129 to the sides,
21x-129=-24
21x=105
After that, you divide the sides by 21 so that you can get your answer
5
So therefore, your answer will be x=5
Tenths is 73.9 hundredths is 73.91
Answer to first part 1: First you obtain number of intervals you would like to have by getting the square root of the total number of observations. In this case, square root of 14 = 3.74; round up and use 4.0.
Answer to Second part: 2: The interval width is then obtained by dividing the range by the number of intervals. For this case, interval width = (42-9)/4 = 8.25. This can be rounded up to the convenient evenfigure of 10.0.
Hope this helps!!!!
