Answer:   63.9

<u>Step-by-step explanation:</u>

ΔEDH ~ ΔEGD

Set a proportion to solve for ED.  

Then set up a proportion to solve for x.

\dfrac{ED}{EH}=\dfrac{EG}{ED}\quad \rightarrow \quad \dfrac{ED}{112}=\dfrac{99.2}{ED}\quad \rightarrow \quad ED^2=112(99.2)\quad \rightarrow \quad  ED=105.4\\\\\\\dfrac{DG}{DH}=\dfrac{EG}{ED}\quad \rightarrow \quad \dfrac{62}{x+2}=\dfrac{99.2}{105.4}\quad \rightarrow \quad 62(105.4)=99.2(x+2)\\\\\\62(105.4)=99.2(x+2)\\\\6535.2=99.2(x+2)\qquad \text{simplified left side}\\\\65.9=x+2\qquad \text{divided both sides by 99.2}\\\\63.9=x\qquad \text{subtracted 2 from both sides}

Answer:

\sqrt{10+4\sqrt{6 } = 4.44948

or = \sqrt{6}  + 2

<em>step by step...solving </em>

<em>10 + 4</em>\sqrt{6}<em />

<em>add/subtract </em>\sqrt{6}<em>² = 6</em>

<em>=10 + 4</em>\sqrt{6}<em> + </em>\sqrt{6}<em>² - 6</em>

<em>Refine</em>

<em>= </em>\sqrt{6}<em> ² + 4</em>\sqrt{6}<em> + 4</em>

<em>rewrite </em><em>↑</em><em> as </em>\sqrt{6}<em>² + 2</em>\sqrt{6}<em> * 2 + 2²</em>

<em>apply Perfect Square Formula (a + b)² = a² + 2ab +²</em>

<em>a = </em>\sqrt{6}<em>, b=2</em>

<em>= (</em>\sqrt{6}<em> + 2)²</em>

<em>= </em>\sqrt \sqrt({6}+ 2)<em>2square    </em>

<em>(the 2 square would not fit like i wanted it to)</em>

<em>apply radical rule </em>\sqrt[n]{a^{n} } = a<em>, assuming a ≥ 0</em>

<em>= </em>\sqrt{6} + 2<em />

posting others as picture (have an account with Symbolab to help me as well.  Just taking too long to type in the step by step if you need it.  all pictures have the decimal result.

Solve the logarithmic equation for x.
aev [14]

Answer:

x = 2   or  x = 4

Step-by-step explanation:

Solve:   2 log x = log 2 + log(3x - 4)

log (x^2) =  log 2 + log (3x - 4)

log (x^2) = log [2*(3x - 4)]

x^2 =  2*(3x - 4)

x^2 = 6x - 8

x^2 - 6x + 8 = 0

factor:

(x - 2 )(x - 4) = 0

x = 2   or  x = 4

Use the given degree of confidence and sample data to construct a confidence interval
ValentinkaMS [17]

Answer:

0.726 < p < 0.874

Step-by-step explanation:

p = 64/83 = about 0.8

confidence interval = p +- z \sqrt{\frac{p (1-p)}{n} }

= 0.8 +- (1.64 x 0.04472)

= 0.8 +- 0.073343

= (0.726656 and 0.873343)

0.726 < p < 0.874
