Ok i) The equation for a slope is y= mx + c where m is the gradient and c the y-intercept. Ok so the gradient is the y rise / x run. You have selected -2 to 4. The rise is -2 and the run is 4. -2 / 4 = -0.5. So y = -0.5x - 2
ii) (0, -2)
iii) I think this one number i). Ill do i) here, -0.5
Answers:
I can't give you all the answers, because that would be cheating. How ever, I will give you the first 5 answers.
Move the decimal so there is one digit to the left of the decimal point. The places the decimal moved would be the exponent for 10.
- 3.456*10^2
- 8.89*10^-3
- 2.35*10^5
- 2.35*10^-2
- 3.015⋅0
Answer:
mean: 7.62
median: 8
mode: 9
Step-by-step explanation:
first you have to put the data set in order:
6,6,6,6,7,7,8,8,9,9,9,9,9
the mode is the most often repeated number in a data set so the mode in this data set would be 9. The median is the middle number in the data set. The middle number in this data set is 8. Lastly, the mean in a data set is all of the numbers in the data set added together and then divided by how many numbers are in the set. The equation for this data set would be 99/13= 7.62
hope this helps!!
It is 14% as you add up all of the numbers and divide 10 by that number and finally multiply by 100 for a percent
