2 answers:

8 0

The slope-intercept form is y=mx+b y = m x + b , where m is the slope and b is the y-intercept. Find the values of m and b using the form y=mx+b y = m x + b . The slope of the line is the value of m , and the y-intercept is the value of b .

ankoles [38]

Answer:

(0.6430, 0.8170)

Step-by-step explanation:

Given that during a recent drought a water utility in a certain town sampled 100 residential water bills and found out that 73 of the residences had reduced their water consumption over that of the previous year.

Sample size n = 100

Sample proportion p = $\frac{73}{100} =0.73$

q = 1-p = 0.23

Std error of proportion = $\sqrt{\frac{pq}{n} } \\=\sqrt{\frac{0.73*0.27}{100} } \\=0.04440$

95% Z critical value = 1.96

Margin of error = $1.96*0.0444 = 0.0870$

Confidence interval = sample proportion ±margin of error

0.642983946

0.817016054

(0.6430, 0.8170)

son4ous [18]

Answer:

A. 2 ( 10 x − 5 )

D. 10 ( 2 x − 1 )

Step-by-step explanation:

Given expression:

20x − 10

Find the equivalent expression

Check all that applies

A. 2 ( 10 x − 5 )

= 20x - 10

B. 2 ( 2 x − 1 )

= 4x - 2

C. 10 ( 20 x − 10 )

= 200x - 100

D. 10 ( 2 x − 1 )

20x - 10

The correct options are

A. 2 ( 10 x − 5 )

D. 10 ( 2 x − 1 )

Evaluate the surface integral. S x2z2 dS S is the part of the cone z2 = x2 + y2 that lies between the planes z = 4 and z = 5

sammy [17]

The surface $S$ can be parameterized in cylindrical coordinates using

$\mathbf r(u,v)=(x(u,v),y(u,v),z(u,v))=(u\cos v,u\sin v,u)$

where $4\le u\le5$ and $0\le v\le2\pi$ . The surface integral is then equivalent to

$\displaystyle\iint_Sx^2z^2\,\mathrm dS=\int_{v=0}^{v=2\pi}\int_{u=4}^{u=5}(u\cos v)^2u^2\left\|\mathbf r_u\times\mathbf r_v\right\|\,\mathrm du\,\mathrm dv$
$=\displaystyle\sqrt2\int_{v=0}^{v=2\pi}\int_{u=4}^{u=5}u^5\cos^2v\,\mathrm du\,\mathrm dv$
$=\dfrac{3843\pi}{\sqrt2}$
