Hi there!
Since we know that half of the circle is 180 degrees, we start with that. Then, we need to add 40 degrees because of arc DCE. So, the measure of major arc ABD is 220 degrees.
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
Answer:
10 is a constant number, and X is a variable used to hold a specific value.
For number 3.it would be 87/200 and 4. Would be 713/500
I guess you mean that the zeroes are 2 and -3/5.
In factor form the function could be
f(x) = (x - 2)(3x + 5)
expanding we get
f(x) = 3x^2 -x - 10
The situation would come as follows: "During the school fundraiser, did freshman raise more money than seniors?"
The question can only be answered with a yes or no, but it will be done to many first-year students. Which does generate statistics, since it gives the ability to have an inherent variability in the data used to answer the question.
That is, each student will raise a different amount of money. Some first-year students will most likely raise more money than some seniors, and some seniors will raise more than some first-year students.
Therefore, YES is a statistical question.
