Answer:

A(s) = 1/16 square units

Step-by-step explanation:

Neither of them are correct

If we have a rectangle,  and divide  into 4 equals rows    ( by means of three horizontal lines ) we will get 4 rectangles each of which have 1/4 of total area. If after that we get 4 squares in each row the area of each of these squares is 1/4 of the area we got when dividing the rectangle with our three lines of the first case, therefore the area of each final square is:

A(s) = (1/4)/(1/4)

A(s) = 1/16 square units

A sphere and a cube have equal surface areas. The length of one edge of the cube is 1.11 meters. What is the radius of the spher
Nady [450]

Answer:

  0.767 m

Step-by-step explanation:

The area of a cube of edge length s is given by ...

  A = 6s^2

The area of a sphere of radius r is given by ...

  A = 4πr^2

When these two are equal, we have ...

  6s^2 = 4πr^2

  r^2 = 6s^2/(4π)

  r = s·√(3/(2π)) ≈ s·0.690988

The radius of the sphere is about ...

  r ≈ 0.690899×1.11 m

  r ≈ 0.767 m . . . . approximate sphere radius

It is $84.6. You multiply 1.6 by 13 which equals $20.8. Then you multiply 3.1 by 14 which equals $43.4. Then you multiply 1.2 by 17 which equals $20.4. Add them together and you get $84.6. 

Hope this helps:)<span />

PLEASE HELP SUPER FAST WORTH ALOT OF POINTS

Answer:

1) 78.87%

2) 99.7%

Step-by-step explanation:

The z-score for a normal distribution is given by:

z=\frac{X-\mu}{\sigma}

1- The given data is:

σ = 4 years

μ = 50 years

For X = 45 and X =55

z_1=\frac{45-50}{4}\\z_1=-1.25\\z_2=\frac{55-50}{4}\\z_2=1.25

A z-score of -1.25 corresponds to the 10.57th percentile of a normal distribution, while a z-score of 1.25 is equivalent to the 89.44th percentile.

Therefore, the percentage of the alligators are between 45 and 55 years old is:

P=89.44-10.57=78.87\%

78.87% of alligators.

2- The given data is:

σ = 2 minutes

μ = 17 minutes

For X = 11 and X =23

z_1=\frac{11-17}{2}\\z_1=-3\\z_2=\frac{23-17}{2}\\z_2=3

A z-score of -3.0 corresponds to the 0.135th percentile of a normal distribution, while a z-score of 3.0 is equivalent to the 99.865th percentile.

Therefore, the percentage of people that should be seen by the doctor between 11 and 23 minutes is:

P=99.865-.0135=99.73\%

99.7% of people.
