Mathematics
1 answer:
zmey [24]4 years ago
8 0
The closer the set of data is to a line the closer the correlation coefficient is to 1

in a you can see somewhat of a line so you should pick a value between 0.5 and 0.7

in b you can see a line, the value you should estimate should be greater than 0.9

In c you kinda maybe imagine a line, but worse than a.  so you should pick a number between 0.2 and 0.4

Car a is 30 miles ahead of car b car a is going 60 mph and car b is going 70 mph how long will it take car b to catch car a
frez [133]

Answer:

3 hours

Step-by-step explanation:

After one hour, car a will be only 20 miles ahead of car b, after two hours, car a will only be 10 miles ahead of car b, and after 3 hour, they will both be equal. This is because car b is going 10 mph faster than car a, because 70-60=10. every hour, car b will catch up to car a by 10 miles.

Leave a thanks if I am correct

What is the place value of the underlined digit the number is 3,729,760
levacccp [35]

I'm not sure which digit is underlined, so I will give you all of them...

3,729,760 = 3,000,000

3,729,760 = 700, 000

3,729,760 = 20,000

3,729,760 = 9,000

3,729,760 = 700

3,729,760 = 60

3,729,760 = 0

PLEASE RATE AS THE BRAINLIEST ANSWER! THANK YOU! :)

James sees a truck at the dealership for $50,000
vova2212 [387]

Answer: B

Step-by-step explanation:
1. 50000+1700+2200 = 55300

2. To find 80% trade in free, all we have to do is figure out 80% of 5000 (because thats the cost of his original car) which is 4000. (5000/100 x 80 = 4000)

3. Then you want to subtract 55300 - 4000 because hes trading in the car which means to subtract from the price.

4. Lastly there is a 1200$ destination fee, so you add on 51300+1200 which equals to 52500
