Answer:

No, they are not Pythagorean triple

Step-by-step explanation:

Pythagorean's theorem,

Hypotenuse² = base² + altitude²

              23² =  21² + 9²

             529 = 441 + 81

            529 ≠ 522

As 9 , 21 , 23 doesn't satisfies Pythagorean theorem, they are not Pythagorean triple

Two owners of a cattle ranch, Jo and Val, want to find the average weight for the ranch's 200 cows. Instead of weighing all of t
Zolol [24]

Answer:

The  value  is E =19.6

Step-by-step explanation:

From the question we are told that

  The mean of Jo  cows is  \= x_1 = 1350

  The standard deviation of Jo cow is  s_1 =  50

  The mean of Val  cows is \= x_2  = 1420

   The standard deviation of Val  cows  is  s_2 =  50

    The sample size for both Val  and  Jo  is  n = 25

Let assume that the level of significance is  \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} }

Hence margin of error for Jo is  

=>   E = 1.96 *  \frac{50}{\sqrt{25} }

=>   E =19.6

Which of the following are geometric series?
Temka [501]

Answer:

-256 +64 - 16 + 4 - 1

Step-by-step explanation:

A series is the summation of all the terms in a sequence.

So it is only the last three options that qualify to be a series.

The series 2 +5 + 8 + 11 + 14 + 17 has no common ratio. It is not geometric.

The series 1+1+2+3+5+ 8 +13 +21 also has no common ratio. It is not geometric.

The series -256 +64 - 16 + 4 - 1 has a common ratio of

r=\frac{64}{-256}=-\frac{1}{4}

There the only series that is geometric is.

-256 +64 - 16 + 4 - 1
