a) Assume that nothing is known about the percentage of computers with new operating systems. n= (Round up to the nearest integer.) b) Assume that a recent survey suggests that about 87% of computers use a new operating system. (Round up to the nearest integer.) c) Does the additional survey information from part (b) havo much of un offect on the sample size that is required? OA. Yes, using the additional survey information trom part (b) dramatically reduces the sample size. O B. Yes, using the additional survey information from part (b) dramatically increases the sample size. OC. No, using the additional survey information from part (b) does not change the sample size. O D. No, using the additional survey information from part (b) only slightly increases the sample size.

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
