Answer:

x=2.4

Step-by-step explanation

Lets take the info already given. 20 is on the larger triangle and 8 is on the smaller. So the side that matches with X is 6. The relationship between 20 and 8 is 2.5. How? 20/8=2.5. then you divide 6 by 2.5. That equals 2.4. So x=2.4. Hope that helps !

b. Find a 99% confidence interval for mean age of ICU patients using the facts that, in the sample, the mean is 57.55 years and

rjkz [21]

Answer:

<em>99% of confidence intervals for mean age of ICU patients</em>

<em>(53.8920 , 61.2079)</em>

Step-by-step explanation:

<u><em>Explanation</em></u>:-

<em>Given sample mean </em> $x^{-} = 57.55$ <em></em>

Given standard error is determined by

S.E = $\frac{S.D}{\sqrt{n} }$

<em>Given data standard error = 1.42</em>

<em>99% of confidence intervals for mean is determined by</em>

$(x^{-} - Z_{0.01} \frac{S.D}{\sqrt{n} } , x^{-} + Z_{0.01} \frac{S.D}{\sqrt{n} } )$

$Z_{\frac{\alpha }{2} } = Z_{\frac{0.01}{2} } = Z_{0.05} = 2.576$

$(x^{-} - 2.576 S.E , x^{-} + 2.576 S.E)$

$(57.55 - 2.576X 1.42 , 57.55+ 2.576 X1.42)$

(53.8920 , 61.2079)

<u><em>Conclusion</em></u>:-

<em>99% of confidence intervals for mean is determined by</em>

<em>(53.8920 , 61.2079)</em>

35A) arc AC = 360-(100+110+80)=

360-290 = 70°

35B) <em>L</em><em> </em>D = ½× 70 = 35°

35C) <em>L</em><em> </em>AEC = ½(100+70)=½×170= 85°

35D) <em>L</em><em> </em>P = ½(100-70) = ½×30 = 15°

A car rental agency advertised renting a car for $26.95 per day and $0.27 per mile. If David rents this car for 3 days, how many

Lapatulllka [165]

Step-by-step explanation:

1 day = $ 26.95

3 days = 26.95 × 3

= $80.85

Remainder = $100 - $80.85

= $19.15

1 mile = $ 0.27

= $19.15 ÷ $0.27

= 71 miles
