600 is 10 times larger than 60
Answer:
35 ;
32 + v
51.2
Step-by-step explanation:
If each observations in a particular set is increased or decreased by a uniform or fixed number, the mean of the resulting output will also increase by the same amount
Hence,
For 15 observations whose mean is 32
If each observation is increased by 3, then the resulting mean will also increase by 3 ; hence, new mean = 32 + 3 = 35
If each observation is decreased by v ; the resulting mean would also decrease by v ;
32 - v
If each observation is increased by 60% ; the resulting mean will be ;
(1 + 60%) * initial mean
(1 + 0.6) * 32
1.6 * 32 = 51.2
(4, 3) i think lol goodluck
Answer:
a. There is a causation relationship and positive trend between number of hours on homework and higher test scores.
b. 76
Step-by-step explanation:
a. Since the dots all follow a linear progression and increase closely together this is a positive trend and likely a causation relationship.
b. y=7x+41 can predict a test score. x is the number of hours, so if 5 if the number of hours then y=7(5)+41 = 35+41=76
Thats it option (C). Hope it helps!!
