Medicare Hospital Insurance The average yearly Medicare Hospital Insurance benefit per person was $4064 in a recent year. Suppos

horrorfan [7]

Answer:

The answer is "0.0764"

Step-by-step explanation:

Please find the complete question in the attached file.

$\to \mu = \$ \ 4064\\\\\to \sigma = \$ \ 460 \\\\\to \sigma \bar{x} = \frac{\sigma}{\sqrt{n}}\\\\$

$= \frac{460}{\sqrt{21}}\\\\ = \frac{460}{4.58257569}\\\\=100.3802$

$\to P(\bar{x}< \$ \ 3920) = \frac{P((\bar{x} - \mu \bar{x})}{\frac{\sigma \bar{x}$

$\to P(z < -1.43) = 0.0764 \\\\\to P(\bar{x}< \$ \ 3920) = 0.0764\\\\$

Can someone help me out with this please? I suck at fractions

xxMikexx [17]

164 inches x $\frac{1 foot}{12 inches}$ = $\frac{41}{3}$ ft

147 inches x $\frac{1 foot}{12 inches}$ = $\frac{49}{4}$ ft

2 $\frac{1}{4}$ ft = $\frac{9}{4}$

Perimeter = 2L + 2w - 1doorway

= 2 $(\frac{41}{3})$ + 2( $(\frac{49}{4})$ - $\frac{9}{4}$

= $\frac{82}{3}$ + $\frac{98}{4}$ - $\frac{9}{4}$

= $\frac{82}{3}$ + $\frac{89}{4}$

= $(\frac{4}{4} )$ $\frac{82}{3}$ + $(\frac{3}{3} )$ $\frac{89}{4}$

= $\frac{328}{12}$ + $\frac{267}{12}$

= $\frac{595}{12}$

= 49 $\frac{7}{12}$ ft

******************************************************************************

b) 49 $\frac{7}{12}$ ft ÷ 8ft = 6.2

If a phone charges 3% every five minutes then how long will it take for the phone to charge 100%

postnew [5]

To find out how long it will take a phone to charge 100% if it charges 3% every 5 minutes, you have to put it in a fraction.

3/5

3 is the percent charged and 5 is the time.

You have to find out what 100 divided by 3 is. The answer is 33.3.

So,

3/5 times 33.3 is equal to 99.9/166.5.

It will take 166.5 minutes for the phone to charge to about 100%.

hope it helps.

can you choose mine as the brainliest answer
