Answer:
3/13
Step-by-step explanation:
There are 28 students. 1 studies biology but not art. 1 studies neither subject. Therefore, there are 26 students who study art.
Of the 26 students who study art, 6 also study biology. So the probability is 6/26, which reduces to 3/13.
Answer:
A
Step-by-step explanation:
![\dfrac{1}{3}+\dfrac{3}{5}+\dfrac{2}{3}= \left[ \dfrac{1}{3}+\dfrac{2}{3} \right]+\dfrac{3}{5}\\\\\\=\dfrac{3}{3}+\dfrac{3}{5}\\\\\\=1+\dfrac{3}{5}\\\\\\=\dfrac{5}{5}+\dfrac{3}{5}\\\\\\=\dfrac{8}{5}\\\\\\=1\dfrac{3}{5}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B3%7D%2B%5Cdfrac%7B3%7D%7B5%7D%2B%5Cdfrac%7B2%7D%7B3%7D%3D%20%5Cleft%5B%20%5Cdfrac%7B1%7D%7B3%7D%2B%5Cdfrac%7B2%7D%7B3%7D%20%5Cright%5D%2B%5Cdfrac%7B3%7D%7B5%7D%5C%5C%5C%5C%5C%5C%3D%5Cdfrac%7B3%7D%7B3%7D%2B%5Cdfrac%7B3%7D%7B5%7D%5C%5C%5C%5C%5C%5C%3D1%2B%5Cdfrac%7B3%7D%7B5%7D%5C%5C%5C%5C%5C%5C%3D%5Cdfrac%7B5%7D%7B5%7D%2B%5Cdfrac%7B3%7D%7B5%7D%5C%5C%5C%5C%5C%5C%3D%5Cdfrac%7B8%7D%7B5%7D%5C%5C%5C%5C%5C%5C%3D1%5Cdfrac%7B3%7D%7B5%7D)
If the graph is translated 3 up, reflected across the x-axis, and is narrower than the graph y = x², we have; y = -(x² + 3)
<h3>How to carry out translation of a function?</h3>
We are given the original equation of the function as;
y = x²
Now, when we translate the graph 3 units upwards, it means we add 3 units to the function to get;
y = x² + 3
Now, when we reflect across the x-axis, it means we just change the sign of the function to get;
y = -(x² + 3)
