A
Explanation-
Domain is the X, which is also independent. So you look at the first circle, or in more detail, the circle that has arrows pointing AWAY from it.
Answer:
The correct option is (C) (2.769, 3.231).
Step-by-step explanation:
The confidence interval for mean when the standard deviation is not known is:
Given:
Compute the critical value as follows:
**Use a <em>t</em>-table.
The 95% confidence interval for true mean length of the bolt is:
Thus, the 95% confidence interval for true mean length of the bolt is (2.769, 3.231).
The correct option is (C).
Answer:
208
Step-by-step explanation:
First let's find out what each container weighs..
Blue = 4 x 103 = 412
Red = 102 x 2 = 204
Now, Let subtract Blue container by Red Container..
412-204=208
Hence, the blue container weighs 208 more than the red container.
Answer:
The slope is 3/2
Step-by-step explanation:
The first step would be to find two clear points on the graph. You cant really get an exact reading on points between values so you want to get ones that are right on the mark.
On your graph I can clearly see the points (30,60) and (50,90).
From here you just use the formula to find the slope. ((y2-y1)/x2-x1))
90-60=30
50-30=20
30/20 can then be reduced to 3/2.
Hope this made sense!
