Answer:
1/4
Step-by-step explanation:
Notice that there are 8 scale divisions between -1 and 0.
So, if you begin at 0 and move one division to the left, you'll be at -1/8.
If you move another division to the left, you'll be at -2/8.
Finally, -2/8 reduces to -1.4 (answer)
Answer: 0.8137
Step-by-step explanation:
As per given , we have

Sample size : n= 47
Let
be the sample mean o.
Then, the probability that the mean of a sample of 47 families will be between 16.6 and 17.6 pounds will be :


[∵
]

[By using p-value calculator]

Hence, the probability that the mean of a sample of 47 families will be between 16.6 and 17.6 pounds= 0.8137
It is the third one on the graph.
Answer:
it should be
C. y = 2x +2
Step-by-step explanation:
Answer:
A) 1/12 lb.
.. (1 2/3)/20 = 1/20 + (2/3)*(1/20)
.. = 1/20 + 1/30
.. = 3/60 + 2/60
.. = 5/60 = 1/12
