Answer:
______________the answer is Y=0.25X-3.25_______
8 employees exercise at least three times a week
<em><u>Solution:</u></em>
At the office where Mika works 41% of the 19 employees exercise at least three times a week
To find: Number of people who exercise at least three times a week
From given information,
Total employees = 19
Employees exercise at least three times a week = 41 % of total employees
Therefore, we have to evaluate 41 % of 19
Number of people exercise at least three times week = 41 % of 19
![\rightarrow 41 \% \text{ of } 19 = 41 \% \times 19\\\\\rightarrow 41 \% \times 19 = \frac{41}{100} \times 19 = 0.41 \times 19\\\\\rightarrow 41 \% \times 19 = 0.41 \times 19 = 7.79 \approx 8](https://tex.z-dn.net/?f=%5Crightarrow%2041%20%5C%25%20%5Ctext%7B%20of%20%7D%2019%20%3D%2041%20%5C%25%20%5Ctimes%2019%5C%5C%5C%5C%5Crightarrow%2041%20%5C%25%20%5Ctimes%2019%20%3D%20%5Cfrac%7B41%7D%7B100%7D%20%5Ctimes%2019%20%3D%200.41%20%5Ctimes%2019%5C%5C%5C%5C%5Crightarrow%2041%20%5C%25%20%5Ctimes%2019%20%3D%200.41%20%5Ctimes%2019%20%3D%207.79%20%5Capprox%208)
Thus approximately 8 employees exercise at least three times a week
X^2 - 7x + 12 = 0
x^2 - 4x - 3x + 12 = 0
x (x - 4) -3 ( x - 4) = 0
(x - 4) (x - 3) = 0
x = 3 , 4
Check the answer by plugging in 3 and 4 for x, if the equation equals zero then you have your answer.
What are you asking anyways hope you get a good grade
