2010-2005= 5 years. 14550-12000=2550
2550/5 = ans = 510 cds/year
Answer: cumulative frequency
Step-by-step explanation:
- A frequency is the number of times a data value occurs.
- A relative frequency is the fraction or proportion of times an answer occurs.
- The cumulative frequency analysis is the analysis of the frequency of occurrence of values of a phenomenon less than a reference value.
In a data set, the cumulative frequency for a value x is the total number of scores that are less than or equal to x.
Hence, cumulative frequency represents the number of times all outcomes less than a given outcome occur.
Answer: (4,8) which is choice A
f = 2/3 is the scale factor
x = 6 and y = 12 pair up to get the coordinates for point K's location
multiply f by x and y to get the new location
f*x = (2/3)*6 = (2/3)*(6/1) = (2*6)/(3*1) = 12/3 = 4
f*y = (2/3)*12 = (2/3)*(12/1) = (2*12)/(3*1) = 24/3 = 8
The results we get are 4 and 8. So (6,12) moves to (4,8)
This scale factor 2/3 = 0.667 is less than 1, so the image is smaller compared to the pre-image.
