The answer is D f(x)=2(4^x)+3
No the answer is 89 because 97 - 8 is 89
Hey there! I'm happy to help!
When rotating a point 90 degrees clockwise about the origin, our original point (x,y) becomes (-y,x), because it is now at a negative y-value.
We see that our point P is at (1,2). We can use this rotation formula to find the coordinates of P' (the new spot where P is)/
(x,y)⇒(-y,x)
(1,2)⇒(-2,1)
Therefore, the coordinates of the point P' are (-2,1).
Have a wonderful day! :D
The frequency refers to how many times a test scores within that particular range.
To find this answer, we must divide the number of scores we are interested in by the number of total scores, aka (n/500).
We are interested in the range of 70-89, and we notice there are 2 boxes included in this range: 70-79 and 80-89.
In the 70-79 range we see that there are 172 out of 500 scores.
In the 80-89 range we see that there are 105 out of 500 scores.
If you add these scores, you are given 277 out of 500 scores, aka (277/500), which gives us 0.554
You were on the right track with the answer you chose but you just forgot to include the 80-89 range. Hope this helps!
