PLEASE ANSWER QUICKLY: SURFACE AREA If you don't know the answer please don't guess.

dusya [7]

Well for one, the floor and the ceiling do not need wallpaper. So you would only find the surface area each side. (48, 48, 80, 80) Then you would add all four together. (256ft squared)

The answer is 'C.'

natulia [17]

when u have a common a denominator then you just add the numerator that would be 7 and 9. 7 + 9= 16

A nurse infuses a dose in 50 minutes. She needs to infuse the dose at a 20% faster rate. How much time does she need ?

dexar [7]

Answer: She would need 40 minutes to infuse a dose.

Step-by-step explanation:

Since we have given that

Number of minutes a nurse takes to infuse a dose = 50 minutes

Rate faster by 20%

So, if the initial rate = 100%

After increasing the rate,

rate becomes 100%-20% = 80%

So, Number of minutes taken to infuse a dose now is given by

$\dfrac{80}{100}\times 50\\\\=0.8\times 50\\\\=40\ minutes$

Hence, she would need 40 minutes to infuse a dose.

In the survey of 891 US adults who follow baseball in a recent year, 184 said that the Boston red sox would win the world series

Norma-Jean [14]

Answer:

90% confidence interval for the population proportion of US adults who follow baseball

( 0.1842 , 0.22880)

Step-by-step explanation:

Explanation:-

Given data the survey of 891 US adults who follow baseball in a recent year, 184 said that the Boston red sox would win the world series.

The sample proportion $'p' = \frac{184}{891} = 0.20650$

q = 1-p = 1- 0.20650 =0.79350

Confidence intervals

90% confidence interval for the population proportion of US adults who follow baseball 

 $(p-Z_{\alpha } \sqrt{\frac{pq}{n} } , p + Z_{\alpha } \sqrt{\frac{pq}{n} } )$ 

The tabulated value Z₀.₉₀ = 1.645

 $(0.20650-1.645\sqrt{\frac{0.20650X0.7935}{891} } , 0.20650 + 1.645\sqrt{\frac{0.20650X0.7935}{891} } )$ 

(0.20650 - 0.02230 , 0.20650+0.02230)

( 0.1842 , 0.22880)

Conclusion:-

90% confidence interval for the population proportion of US adults who follow baseball

( 0.1842 , 0.22880)
