44 students would choose computer games because 20+14+24=54 students in total 44 + 14=54
Answer:
(9,-5)
Step-by-step explanation:
The equation of an ellipse can be represented as
![\frac{(x-h)^{2} }{b^{2}} +\frac{(y-k)^{2}}{a^{2}} =1](https://tex.z-dn.net/?f=%5Cfrac%7B%28x-h%29%5E%7B2%7D%20%7D%7Bb%5E%7B2%7D%7D%20%2B%5Cfrac%7B%28y-k%29%5E%7B2%7D%7D%7Ba%5E%7B2%7D%7D%20%3D1)
where (h,k) is the center.
In ![\frac{(y+5)^{2}}{121} +\frac{(x-9)^{2}}{49} =1](https://tex.z-dn.net/?f=%5Cfrac%7B%28y%2B5%29%5E%7B2%7D%7D%7B121%7D%20%2B%5Cfrac%7B%28x-9%29%5E%7B2%7D%7D%7B49%7D%20%3D1)
We can see the h and k values are 9 and -5 respectively, so the center is (9,-5)
Answer:
85 is the answer because it goes down by 3.5.
Step-by-step explanation:
100-.5=99.5, 99.5-1=98.5, 98.5-1.5=97, 97-2=95, 95-2.5=92.5, 92.5- 3= 89.5, 89.5-3.5=85, then 85-4=81, then so on.
