5*13
that is all answers one through twelve
Step-by-step explanation:
Answer:
i guess it's the second one, 16x2+9y2, since they are both raised to 2 and they are binomial
Answer: a. n= 1068
b. n= 164
Step-by-step explanation:
The formula to find the sample size :

, where p=prior population proportion , z* = critical z-value and E = Margin of error.
Here , let p=proportion of computers that use a new operating system.
Given : Confidence level = 95%
i.e. z* = 1.96 [by z-table]
Margin of error : E = 3% =0.03
a. If p is unknown , then we assume p=0.5
Then, 
i.e. n= 1068
b. p=0.96
Then, 
i.e. n= 164.
Using the correct order of operations, your equation would simplify as:
-36 - 10 = -26
