Answer:
1455
Step-by-step explanation:
0.03% x 1500 = 45
therefore, 45 students were late
1500 - 45 = 1455 punctual
Answer: LAST OPTION
Step-by-step explanation:
The complex numbers shown have the form:
![a+bi](https://tex.z-dn.net/?f=a%2Bbi)
By definition, the distance can the distance of the complex number from the origin on the complex plane can be calculated with the formula shown below:
![d=\sqrt{a^2+b^2}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7Ba%5E2%2Bb%5E2%7D)
Substitute values of each option. Then:
1) ![d=\sqrt{2^2+15^2}=\sqrt{229}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B2%5E2%2B15%5E2%7D%3D%5Csqrt%7B229%7D)
2) ![d=\sqrt{17^2+1^2}=\sqrt{290}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B17%5E2%2B1%5E2%7D%3D%5Csqrt%7B290%7D)
3) ![d=\sqrt{20^2+(-3)^2}=\sqrt{409}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B20%5E2%2B%28-3%29%5E2%7D%3D%5Csqrt%7B409%7D)
4)
(CORRECT OPTION)
I don’t know what the answer is I wish I could help
14x Is the answer Because 7 times two is fourteen and plus four (X) would be sixteen then subtracted by two so it would be 14x
Answer: Choice B
![x+5y = 11\\4x-6y = -3](https://tex.z-dn.net/?f=x%2B5y%20%3D%2011%5C%5C4x-6y%20%3D%20-3)
=====================================
Explanation:
The given matrix is
![\left[\begin{array}{cc|c}1&5&11\\4&-6&-3\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7Cc%7D1%265%2611%5C%5C4%26-6%26-3%5Cend%7Barray%7D%5Cright%5D)
The numbers to the right of the vertical bar represent the values on the right hand side of each equation in the final answer.
The numbers to the left of the bar represent the x and y coefficients of the equations. The first number of any given row is the x coefficient. The second number is the y coefficient.
For instance, the first row has
to indicate the x coefficient is 1, and the y coefficient is 5. We end up with 1x+5y or simply x+5y. Putting everything together, the first equation would be x+5y = 11
Through similar steps, the second equation is 4x-6y = -3
