Answer:

y = - $\frac{1}{6}$ x - $\frac{8}{9}$

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Rearrange 3x + 18y = - 16 into this form

Subtract 3x from both sides

18y = - 3x - 16 ( divide all terms by 18 )

y = - $\frac{3}{18}$ x - $\frac{16}{18}$ , that is

y = - $\frac{1}{6}$ x - $\frac{8}{9}$ ← in slope- intercept form

Hatshy [7]

Answer:

X=125/64

Step-by-step explanation:

x^2+4 x-5=0

x^2+4x=5

4x^3=5

x^3=5/4

x=5^3/4^3

x=125/64

Verify the identity. cotangent x equals StartFraction 1 plus cosine 2 x Over sine 2 x EndFractioncot x= 1+cos2x sin2x Use the ap

lutik1710 [3]

Answer with Step-by-step explanation:

We are given that

RHS

$\frac{1+Cos2x}{Sin2x}$

We have to verify the identity.

We know that

$1+Cos2x=2Cos^2 x$

$Sin2x=2SinxCos x$

Using the formula

$\frac{2Cos^2x}{2SinxCosx}$

$\frac{Cosx}{Sinx}$

$Cot x$

By using the formula

$Cotx=\frac{Cosx}{Sinx}$

LHS=RHS

Hence, verified

Find the critical value of x2 based on the given information H1 >3.5 n=14 a=0.05

egoroff_w [7]

Answer:

The degrees of freedom are given by:

$df = n-1=14-1=13$

The significance level is $\alpha=0.05$ and then the critical value can be founded in th chi square table we need a quantile that accumulates 0.05 of the area in the right tail of the distribution and for this case is:

$\chi^2_{\alpha}= 22.362$

And if the chi square statistic is higher than the critical value we can reject the null hypothesis in favor of the alternative.

Step-by-step explanation:

We have the followign system of hypothesis:

Null hypothesis: $\sigma^2 \leq 3.5$

Alternative hypothesis: $\sigma^2 >3.5$

The degrees of freedom are given by:

$df = n-1=14-1=13$

$\chi^2_{\alpha}= 22.362$

And if the chi square statistic is higher than the critical value we can reject the null hypothesis in favor of the alternative.
