Answer above is wrong!!! You couldn’t have popped 5 since you just stated that you popped3 in fifteen minutes.
To get the right answer you divide the number of bags you popped by the time. This being: 3 divided by 15=0.2
You popped 0.2 bags per minute!
Answer:
1. 5
2. 5
3. -3
4.y= -1
5. 5
Step-by-step explanation:
1.)x- 2y= -25 ; y=3x
x-2(3x)=(-25)
x-6x=(-25) ; -5x=(-25) ; x=5
2.) 5x+3y =40; x=y
8y=40; y=5
3.) 4x-3y= -27; x=3y
4(3y)-3y= -27; 12y-3y=-27; 9y=-27; y=-3
4.)x-y=9; x=-8y; -8y-y=9; -9y=9; y=-1
5.) 2x+2y=30; y=2x ; 2x+2(2x)=30; 6x=30; x=5
Answer:
The confidence interval is , in which n is the size of the sample.
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Z-table as such z has a p-value of .
That is z with a pvalue of , so Z = 1.96.
Now, find the margin of error M as such
In which is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is
The upper end of the interval is the sample mean added to M. So it is
The confidence interval is , in which n is the size of the sample.
Question:
Solution:
Let the following function:
if we evaluate this function at the point d=1, we get:
note that there is no number that multiplied 4 times gives you -1. Therefore, the value of this function does not exist.
Then, by problem notation, we get that the correct answer is:
