So, 9 out of 10 students prefer class, so, obviously, it would not be 100. It would be 150. So in conclusion, 50 students prefer lunch over math class, whilst 150 other students prefer math class over lunch.
Answer:
The probability of the tip to be more than 200 is 0.1.
Step-by-step explanation:
As per the given data
Amount of tip Number
0-20 200
20-50 100
50-100 75
100-200 75
200+ 50
____________________
Total= 500
So what is the probability of tip to be more than 200 is given as

From the table the value is 50 for the tip to be more than 200 where as the total occurrences are 500 so substituting values:

So the probability of the tip to be more than 200 is 0.1.
Answer:
B. It makes the graph really narrow.
Step-by-step explanation:
![\displaystyle Y = A[X - H]^2 + K](https://tex.z-dn.net/?f=%5Cdisplaystyle%20Y%20%3D%20A%5BX%20-%20H%5D%5E2%20%2B%20K)
In the Vertex Formula, any <em>fraction</em><em> </em>you store in for <em>A</em><em> </em>will result in a <u>vertical</u><u> </u><u>shrink</u>, widening the graph, whereas any <em>whole number</em> you store in for <em>A</em> will result in a <u>vertical stretch</u>, narrowing the graph.
