What's the equation with a slope of -4 that goes through (-1,1)? find it

$\Large\maltese\underline{\textsf{B. This problem has been solved!}}$

The equation used, here is $\bf{y-y1=m(x-x1)}$ .

$\bf{y-1=-4(x-(-1)}$ | simplify after putting in the information given

$\bf{y-1=-4(x+1)}$

$\rule{300}{1.7}$

$\bf{Result:}$

$\bf{=y-1=-4(x+1)}$

$\boxed{\bf{aesthetic\not101}}$

Which of the following is not true when using the confidence interval method for testing a claim about μ when σ is unknown? Cho

sp2606 [1]

Answer:

The P-value method and the classical method are not equivalent to the confidence interval method in that they may yield different results ( A )

Step-by-step explanation:

The False statement about using the confidence interval method when testing a claim about μ when σ is unknown is ; The P-value method and the classical method are not equivalent to the confidence interval method in that they may yield different results

This is because sometimes the values gotten from the p-value and confidence interval differs and this occurs mostly when the sample size is very small.

Which of the following is a solution of x2 + 4x = −8?

Vladimir [108]

$x^{2}+4x = -8
\\\\
x^{2}+4x+8 = 0
\\\\
\Delta = b^{2}-4ac
\\\\
\Delta = (4)^{2}-4 \cdot (1) \cdot (8)
\\\\
\Delta = 16-32
\\\\
\Delta = -16$

There's no solution in the set of real numbers.

$\boxed{S = \{ \ \ \}}$

Evaluate the line integral ?Cx2zds, where C is the line segment from (0,5,2) to (2,7,8).

Leno4ka [110]

Parameterize $C$ by

$\mathbf r(t)=(x(t),y(t),z(t))=(1-t)(0,5,2)+t(2,7,8)=(2t,5+2t,2+6t)$
$\implies\mathrm ds=\sqrt{\left(\dfrac{\mathrm dx}{\mathrm dt}\right)^2+\left(\dfrac{\mathrm dy}{\mathrm dt}\right)^2+\left(\dfrac{\mathrm dz}{\mathrm dt}\right)^2}\,\mathrm dt=\sqrt{44}\,\mathrm dt$

So the line integral is equivalent to

$\displaystyle\int_Cx^2z\,\mathrm ds=\sqrt{44}\int_{t=0}^{t=1}(2t)^2(2+6t)\,\mathrm dt=\frac{52\sqrt{11}}3$
