The <em><u>correct answer</u></em> is:
c)75.4 to 94.6
Explanation:
The formula for a confidence interval is:
,
where μ is the mean, z is the z-score associated with the level of confidence we want, σ is the standard deviation, and n is the sample size.
Our mean is 85, our standard deviation is 12, our sample size is 6, and since we want 95% confidence, our z-score is 1.96:

Answer:I think the answer is 6x because
18= 6x3
42= 6x7
30= 6x5
Step-by-step explanation:
18= 6x3
42= 6x7
30= 6x5 And 6x(3x+7x^3+5x^4) it became 18x^2+42x^4+30x^5
Answer:
72.7
Step-by-step explanation:
First multiply 72 by 10
because 72 is 72 10s, making it a whole number.
then add 720 (72 times 10) to 7.
then all of that over 10.
then just divide.
727/10
72.7
this is what you do for all mixed numbers like that one.
<span> A. x²+2 - a polynomial
B.(x⁸-2)/(x⁻²+3) rational function
C. 7x⁷-2x⁻⁴+3 (It has negative value of exponent, so it cannot be a polynomial.)
D.x^x-1 (x is an exponent it cannot be a polynomial)</span>
