Answer:

169

Step-by-step explanation:

if S(n)=n^2

so,S(13)=13^2

n=13

n^2=13^2

=169

1<br> 2. Verify that (1 - cos^20) CSc^20 =<br> (4 Points)
dolphi86 [110]
(1-cos^2(x)) csc^2(x)=1

one of the trigonometry rules is sin^2(x) + cos^2(x) = 1 if you rearrange this you realize that sin^2= 1-cos^2(x)

we also know that csc^2(x)= 1/sin^2(x) so now you can rewrite your equation as:

sin^2(x) x 1/sin^2(x) = 1

sin^2(x)/sin^2(x) =1

the LHS (left hand side) can cancel down to 1 because the numerator and denominator are the same

so then 1=1 Therefore LHS=RHS

Hope this helps

Of 585 samples of seafood purchased from various kinds of food stores in different regions of a country and genetically compared
Dafna1 [17]

Answer:

a) The 99% confidence interval is from 14.8% to 23.2%.

b) The confidence interval tells us that the true proportion of mislabeled is within 14.8% and 23.2%, with a 99% confidence. In other words, if we take samples of the same size, 99% of the samples will have a proportion within 0.148 and 0.232.

c) The confidence interval calculation take into account the sample size, so the width (or precision) of the interval depends on the sample size.

The only criticism that could be analyzed is to see if the sample is representative of the population.

Step-by-step explanation:

a) We have to calculate a 99% confidence interval for the proportion.

The sample proportion is p=0.19.

 

The standard error of the proportion is:

\sigma_p=\sqrt{\dfrac{p(1-p)}{n}}=\sqrt{\dfrac{0.19*0.81}{585}}\\\\\\ \sigma_p=\sqrt{0.000263}=0.016

The critical z-value for a 99% confidence interval is z=2.576.

The margin of error (MOE) can be calculated as:

MOE=z\cdot \sigma_p=2.576 \cdot 0.02=0.042

Then, the lower and upper bounds of the confidence interval are:

LL=p-z \cdot \sigma_p = 0.19-0.042=0.148\\\\UL=p+z \cdot \sigma_p = 0.19+0.042=0.232

The 99% confidence interval for the population proportion is (0.148, 0.232).

Alekssandra [29.7K]

Answer:

-0.2084

Step-by-step explanation:

log_{b}( \frac{2}{3} )  \\  \\  =  log_{b}(2)  - log_{b}(3)  \\  \\  =0.3562 -  0.5646 \\  \\  = -0.2084
