Do the top please, been trying for hours to solve
scoray [572]

Answer:

2x+30

Step-by-step explanation:

The perimeter of a rectangle is

P = 2(l+w)

The length is 2/3 x+10  and the width is 1/3x +5

P = 2(2/3x +10 + 1/3x +5)

Combine like terms

P = 2(2/3x + 1/3x +10+5)

   = 2(x +15)

Distribute the 2

   = 2x+30

Suppose a claim is that the average pulse rates of women is μ = 73 and we wish to test this against an alternative hypothesis th
Pachacha [2.7K]

Answer:

P = 0.018

Step-by-step explanation:

In this problem, the null and alterantive hypothesis are:

H_0: \mu=73\\H_1: \mu \ne 73

If the sample has a size of n = 40, the degrees of freedom are 40-1 = 39.

If the value of the test statistic is t = 2.463, we can look up in a t-table to find the p-value. In this test, because the mean can be bigger than 73 or smaller than 73, we have to do a two-tailed test.

For a two-tailed test for t = 2.463 and df = 39, the P-value is P = 0.018.

Find the characteristic polynomial of the matrix a=[−83−310].
rosijanka [135]
Assuming the matrix is

\mathbf A=\begin{bmatrix}-8&3\\-3&10\end{bmatrix}

we have characteristic polynomial given by the equation

\det(\mathbf A-\lambda \mathbf I)=0\iff\begin{vmatrix}-8-\lambda&3\\-3&10-\lambda\end{vmatrix}=0
(-8-\lambda)(10-\lambda)-(-9)=0
\lambda^2-2\lambda-71=0
