Step-by-step explanation:
Candies with celias and emmas is 60 and 45 respectively.
<u>Solution:</u>
Given, Getting home from trick or treat celia and emma counted their candies. Half of celias candies is equal to 2/3 of emmas candies.
They had a total of 105 candies altogether.
We have to find how many candies did each of them have.
Let the number of candies with celias be n, then number of candies with emma will be 105 – n.
Now according to given condition.
![\begin{array}{l}{\frac{1}{2} \times \text { celias candies count }=\frac{2}{3} \times \text { emmas candies count }} \\\\ {\rightarrow \frac{1}{2} \times n=\frac{2}{3} \times(105-n)} \\\\ {\rightarrow 3 \times n=2 \times 2 \times(105-n)} \\\\ {\rightarrow 3 \times n=2 \times 2 \times(105-n)} \\\\ {\rightarrow 3 n=4(105-n)} \\\\ {\quad \rightarrow 3 n=420-4 n} \\\\ {\rightarrow 3 n=420-4 n} \\\\ {\rightarrow 3 n+4 n=420} \\\\ {\rightarrow 7 n=7 \times 60} \\\\ {\rightarrow n=60}\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bl%7D%7B%5Cfrac%7B1%7D%7B2%7D%20%5Ctimes%20%5Ctext%20%7B%20celias%20candies%20count%20%7D%3D%5Cfrac%7B2%7D%7B3%7D%20%5Ctimes%20%5Ctext%20%7B%20emmas%20candies%20count%20%7D%7D%20%5C%5C%5C%5C%20%7B%5Crightarrow%20%5Cfrac%7B1%7D%7B2%7D%20%5Ctimes%20n%3D%5Cfrac%7B2%7D%7B3%7D%20%5Ctimes%28105-n%29%7D%20%5C%5C%5C%5C%20%7B%5Crightarrow%203%20%5Ctimes%20n%3D2%20%5Ctimes%202%20%5Ctimes%28105-n%29%7D%20%5C%5C%5C%5C%20%7B%5Crightarrow%203%20%5Ctimes%20n%3D2%20%5Ctimes%202%20%5Ctimes%28105-n%29%7D%20%5C%5C%5C%5C%20%7B%5Crightarrow%203%20n%3D4%28105-n%29%7D%20%5C%5C%5C%5C%20%7B%5Cquad%20%5Crightarrow%203%20n%3D420-4%20n%7D%20%5C%5C%5C%5C%20%7B%5Crightarrow%203%20n%3D420-4%20n%7D%20%5C%5C%5C%5C%20%7B%5Crightarrow%203%20n%2B4%20n%3D420%7D%20%5C%5C%5C%5C%20%7B%5Crightarrow%207%20n%3D7%20%5Ctimes%2060%7D%20%5C%5C%5C%5C%20%7B%5Crightarrow%20n%3D60%7D%5Cend%7Barray%7D)

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:
see below
Step-by-step explanation:
As with many multiple-choice questions, the appropriate choices can often be determined with a simple test. Here, you only need to look at the values of the constants. (Those are ringed in blue.)
