kap26 [50]

Answer:

B) At alpha = 0.01, there is insufficient evidence to conclude the true mean wind speed at the site exceeds 25 mph.

Step-by-step explanation:

P-value of the test:

The p-value of the test is the probability of finding a sample mean above 25.

We are using the t-distribution, with test statistic t = 1.25 and 43 - 1 = 42 degrees of freedom. This probability is a right-tailed test.

With the help of a calculator, this p-value is of 0.1091.

Since the p-value of the test is 0.1091 > 0.01, at $\alpha = 0.01$ there is insufficient evidence to conclude the true mean wind speed at the site exceeds 25 mph, and the correct answer is given by option B.

Rewrite each expression in the form kkxxnn, where kk is a real number and nn is an integer. Assume x ≠ 0.

labwork [276]

Answer:

The expression will be $2x^5\times x^{10}=2x^{5+10}=2x^{15}$

Step-by-step explanation:

We have given the expression $2x^5\times x^{10}$

We have to write this expression in kkxxnn form , here kk is real number and nn is integer

We know the property of exponent that when two function are multiplied thn their exponent are added

So $2x^5\times x^{10}=2x^{5+10}=2x^{15}$

Here kk = 2 and nn = 15

vampirchik [111]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{2z - 5y}}}}}$

Step-by-step explanation:

$\sf{ - ( - 2z + 5y)}$

Distribute negative ( - ) sign through the parentheses

$\sf{( - ) \times ( - 2z) + ( - ) \times (5y)}$

$\dashrightarrow{ \sf{2z + ( - 5y)}}$

$\dashrightarrow{ \sf{2z - 5y}}$

Hope I helped!

Best regards! :D
