Answer: −1−3k
Step-by-step explanation:
Distribute:
(−3+4k)−1(−2+7k)
(-3+4k)+{2-7k}
Eliminate redundant parentheses:
(−3+4k)+2−7k
-3+4k+2-7k
Add the numbers:
−3+4k+2−7k
−1+4k−7k
Add the same term to both sides of the equation:
−1+4k−7k
−1−3k
Answer:
The sample size used to compute the 95% confidence interval is 1066.
Step-by-step explanation:
The (1 - <em>α</em>)% confidence interval for population proportion is:

The 95% confidence interval for proportion of the bank's customers who also have accounts at one or more other banks is (0.45, 0.51).
To compute the sample size used we first need to compute the sample proportion value.
The value of sample proportion is:

Now compute the value of margin of error as follows:

The critical value of <em>z</em> for 95% confidence level is:

Compute the value of sample size as follows:

Thus, the sample size used to compute the 95% confidence interval is 1066.
Answer:
x=-9
Step-by-step explanation:
distribute 4 into the parentheses
8x+36=-44+8
add -44+8
and u get 8x+36=-36
subtract the 36 on both sides and leave u with
8x=-72
divide 8 on both sides
and ur answer is -9
i dont think this make sense but hope this helps
Hi!
This question is about math.



Explanation: You had to used order of operations on this math problems. Then you can also used P-Parenthesis, E-Exponents, M-Multiply, D-Divide, A-Add, and S-Subtract. ("Please Excuse My Dear Aunt Sally".)
For Example: (65+15*8/2)
