Answer:

Option C.

Step-by-step explanation:

Given information: \triangle ABD\sim \triangle CAD, AB=12, BD=x, BC=27.

In triangle ABC and triangle DBA,

\angle BAC=\angle BDA=90^{\circ}

\angle ABC=\angle DBA                   (Reflexive property)

By AA property of similarity triangle ABC and triangle DBA are similar.

The corresponding parts of similar triangles are proportional.

\dfrac{AB}{CB}=\dfrac{BD}{BA}

\dfrac{12}{27}=\dfrac{x}{12}

Multiply both sides by 12.

\dfrac{12}{27}\times 12=\dfrac{x}{12}\times 12

\dfrac{144}{27}=x

\dfrac{16}{3}=x

Therefore, the correct option is C.

Find the size of each of two samples (assume that they are of equal size) needed to estimate the difference between the proporti
hodyreva [135]

Answer:

The sample size n = 4225

Step-by-step explanation:

We will use maximum error formula = \frac{z_{a} S.D}{\sqrt{n} }

but we will find sample size "n"

\sqrt{n}  = \frac{z_{a} S.D}{maximum error}

Squaring on both sides , we get

n  = (\frac{z_{a} S.D}{maximum error})^2

Given 99% confidence interval (z value) = 2.56

given maximum error = 0.02

n  = (\frac{z_{a} p(1-p)}{maximum error})^2

n≤ (\frac{2.56X\frac{1}{2} }{0.02}) ^{2}    ( here S.D = p(1-p) ≤ 1/2

on simplification , we get n = 4225

<u>Conclusion</u>:

The sample size of two samples is  n = 4225

<u>verification</u>:-

We will use maximum error formula = \frac{z_{a} S.D}{\sqrt{n} } = \frac{2.56 1/2}{\ \sqrt{4225} }  = 0.0196

substitute all values and simplify we get maximum error is 0.02

find an equation of the tangent line to the curve at the given point. y=sqrt(x) (1,1) Ive never been good with these equations a
Nady [450]
Equation of a tangent line of a curve is:
y- y0 = f´ (x0) (x - x0 ).   In this case: x0=1, y0=1
f´(x)=\frac{1}{2 \sqrt{x} }(Derivation)
f´(x0)=\frac{1}{2}
y - 1 = 1/2 ( x - 1 )
y - 1 = 1/2 x - 1/2
y = 1/2 x - 1/2 + 1
y =\frac{1}{2}x+ \frac{1}{2}
