Answer:
1/3
Step-by-step explanation:
39 divided by 13 comes out to 3, meaning that 1 out of 3 students chose to hear the designer speak.
Yesterday's closing price was 7.25.
In order to find this, we take the current price and subtract how much it went up. This will give us the price from before it rose.
7.375 - .125 = 7.25
We want to find one-half of the reciprocal of 7/sqrt(98). Let's write down an expression for this:
![\dfrac{1}{2} \times \dfrac{\sqrt{98}}{7}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B2%7D%20%5Ctimes%20%5Cdfrac%7B%5Csqrt%7B98%7D%7D%7B7%7D)
We can rewrite 98 into ![2 \times 49](https://tex.z-dn.net/?f=2%20%5Ctimes%2049)
![\dfrac{1}{2} \times \dfrac{\sqrt{2 \times 49}}{7}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B2%7D%20%5Ctimes%20%5Cdfrac%7B%5Csqrt%7B2%20%5Ctimes%2049%7D%7D%7B7%7D)
![=\dfrac{1}{2} \times \dfrac{\sqrt{2} \times \sqrt{49}}{7}](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B1%7D%7B2%7D%20%5Ctimes%20%5Cdfrac%7B%5Csqrt%7B2%7D%20%5Ctimes%20%5Csqrt%7B49%7D%7D%7B7%7D)
The square root of 49 is 7
![=\dfrac{1}{2} \times \dfrac{\sqrt{2} \times 7}{7}](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B1%7D%7B2%7D%20%5Ctimes%20%5Cdfrac%7B%5Csqrt%7B2%7D%20%5Ctimes%207%7D%7B7%7D)
![=\dfrac{1}{2} \times\sqrt{2}](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B1%7D%7B2%7D%20%5Ctimes%5Csqrt%7B2%7D)
![=\dfrac{\sqrt{2}}{2}](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B%5Csqrt%7B2%7D%7D%7B2%7D)
