Answer:

54 9/10

Step-by-step explanation:

The perimeter is the sum of all the sides

13 1/4 + 12 1/5 + 18 1/4 + 11 1/5

Add up the whole numbers

13+12+18+11 = 54

1/4+1/5+1/4+1/5

2/4+2/5

1/2+2/5

Get a common denominator

1/2*5/5 + 2/5*2/2

5/10 +  4/10

9/10

Add them back together

54 9/10

When finding the margin of error for the mean of a normally distributed population from a sample, what is the critical probabili
svlad2 [7]

Critical probability is the essentially cut-off value. The critical probability when the confidence level of 58% is 0.79.

<h3>What is the critical probability?</h3>

Critical probability is the essentially cut-off value that defines the region where the test statistic is unlikely to lie.

As it is given that the confidence level is 58%. therefore, in order to calculate the critical probability, we need to calculate the margin of error within a set of data, and  it is given by the formula

\rm Critical\ Probability, (P*) = 1-\dfrac{\alpha }{2}

where the value of the α is expressed as,

\alpha= 1 -\dfrac{\rm Confidence\ interval}{100}

Now, as the confidence interval is given to us, therefore, the value of the alpha can be written as,

\alpha= 1 -\dfrac{\rm 58\%}{100} = 0.42

Further, the critical probability, assuming a confidence level of 58% is,

\rm Critical\ Probability, (P*) = 1-\dfrac{\alpha }{2}\\\\\rm Critical\ Probability, (P*) = 1-\dfrac{0.42}{2} = 0.79

Hence, the critical probability is 0.79.

Factor completely, then place the factors in the proper location on the grid.<br> x^2n + 10x^n + 16
postnew [5]

Answer:

(x^n + 2)(x^n + 8)

Step-by-step explanation:

The polynomial x^{2n}+10x^n + 16 can be factored exactly the same as the polynomial x^2 + 10x + 16. Here it factors into two numbers which multiply to 16 but add to 8. These factors are 8 and 2. So it factors into the expression (x+8)(x+2).

For the polynomial x^{2n}+10x^n + 16 it factors into the same factors except x ^n is used instead. The factors are (x^n + 2)(x^n + 8)

Which of these is a complex number? <br><br> A. <br><br> B. <br><br> C. <br><br> D.
Step2247 [10]

Answer:

option D

\frac{8}{3} + \sqrt{\frac{-7}{3} }

Step-by-step explanation:

Given in the question are 4 number

5√1/3 - \frac{9}{\sqrt{7} }

2 - \frac{1}{\sqrt{11} }

9 + 3\sqrt{\frac{5}{2} }

\frac{8}{3} + \sqrt{\frac{-7}{3} }

A Complex Number is a combination of a Real Number and an Imaginary Number

<h3>Example </h3>

a + ib

where a is real number

            b is imaginary number

            i is 'lota' which is √-1

<h3>So according to the definition above </h3>

\frac{8}{3} + \sqrt{\frac{-7}{3} } is complex number in which

\frac{8}{3} is real part

\sqrt{\frac{7}{3} } \sqrt{-1} = \sqrt{\frac{7}{3} } i is the imaginary part
