Answer:
Option: A is the correct answer.
The number of weeds is decreasing by a multiplicative rate.
Step-by-step explanation:
Clear;y from the scatter plot we could observe that with the increasing value of one variable the other variable is decreasing.
Hence, The number of weeds is decreasing.
Also as we could see that the line of best fit is a curve and not a line Hence, the number of weeds are not decreasing by a additive rate ( since the rate or a slope of a line is constant) it is decreasing by a multiplicative rate.
<em>Based on the graph of a regression model:</em>
<em>Option: A is correct.</em>
Answer:
84 grams; 5 ounces
Step-by-step explanation:
1oz = 28g
3*1oz = 3*28g

Pretty much all angles that add up to be 180
A man invests $2000 into an account that accrues 8.5% interest compounded quarterly. He made the deposit of 2 years , i.e. for 8 quarters ( or 8 compounding periods)
Amount after n years is calculated by following equation :
Amount = Principal * ( 1 + Interest rate per compounding period ) ^ no. of compounding periods
The amount in his account after 2 years = 2000 * ( 1 + 0.085/4) ^ 8
= 2000 * (1.02125 ) ^ 8
= 2000 * 1.18319
= $2366.39
The mean is the average. the median is the middle number. to find the mean, add all the numbers in the list and divide it by how many numbers there are. add 2+ 11 + 11 + 11 + 12 + 12 + 13 + 14 + 14 + 15 and divide them by 10. that’ll be your mean. to find the median, place them all in number order. the middle number is your answer
