Answer:
65.03 meters
Step-by-step explanation:
The line of best fit, for the distance of the winning throw, in x years after 1980 is:
Using the line of best fit, estimate what the distance of the gold medal winning discus throw was in 1980.

Answer: 34
Step-by-step explanation: the ratio is 3:2 we know that there are 51 orange sweets but we don’t know how many are yellow so the current ratio is 51:x we need to find x so if we divide 3 by 51 the answer is 17 so we need to multiply 17 by 2 which is 34 so x is equaled to 34 the final ratio is 51:34
hope it helped :)
