1. 9(3)+3 = 27+3 = 30
2. 9( $8^{4}$ ) = 9(4096) = 36864
3. 9-6+3 = 6
4. 6(5)+30 = 30+30 = 60
5. 6( $8^{3}$ ) = 6(512) = 3072
6. ( $8^{3}$ )+84 = 512+84 = 596
7. 200+51 = 251
8. 3(18)+ $18^{2}$ = 54+324 = 378
9. 12(24)-36 = 288-36 = 252
10. 4(11+90)+10 = 44+280+10 = 334
11. 8-8 = 0
12.14(95)-1264+1 = 1330-1264+1 = 66+1 = 67

Plugging 10 for k in the expression gives us
$2(10)^2+5(10)+1$ We simplify this expression to $200+50+1=251$
251 is your answer

Answer:

The 95% confidence interval is $9.15< \mu < 11.45$

Step-by-step explanation:

From the question we are told that

The sample size is n = 26

The mean is $\= x = 10.3$

The standard deviation is $s = 3$

From the question we are told the confidence level is 95% , hence the level of significance is

$\alpha = (100 - 95 ) \%$

=> $\alpha = 0.05$

Generally from the normal distribution table the critical value of $\frac{\alpha }{2}$ is

$Z_{\frac{\alpha }{2} } = 1.96$

Generally the margin of error is mathematically represented as

$E = Z_{\frac{\alpha }{2} } * \frac{\sigma }{\sqrt{n} }$

=> $E = 1.96 * \frac{3}{\sqrt{26} }$

=> $E = 1.1532$

Generally 95% confidence interval is mathematically represented as

$\= x -E < \mu < \=x +E$

=> $10.3 -1.1532 < \mu < 10.3 + 1.1532$

=> $9.15< \mu < 11.45$
