Answer:
And the value for n rounded up would be n = 174
Step-by-step explanation:
We have the following info given:
previous estimation for the deviation
the margin of error desired
represent the confidence
The Margin of error is given by:
If we solve for the value of n we got:
For this problem we know that the confidence is 98% so then the significance level would be 
and the critical value would be:
And replacing we got:
And the value for n rounded up would be n = 174
-2x^3 - 2x^2 + 12x
= -2x (x^2 + x - 6)
= -2x(x + 3)(x - 2)
Its D
The last digit of the product of all the numbers between 11 and 29 is 0.
A product is something that has undergone one or more multiplications.
Here, we're looking for the final digit of the product of all whole numbers greater than 11 and less than 29.
Next, we have the product as: 12*13*14*15*16*17*18*19*20*21*22*23*24*25*26*27*28
Now take note of the 20 that is present.
Any number multiplied by 20 will result in a zero, so:
Product = 20*(12*13*14*15*16*17*18*19*21*22*23*24*25*26*27*28)
Using only that, we can infer that 0 represents the final digit in the product of all the numbers between 11 and 29.
