Answer:

Prime Factorization of 576

576=2\times 2\times 2\times 2\times 2\times 2\times 3\times 3

Prime Factorization of 64

64=2\times 2\times 2\times 2\times 2\times 2

The Expression in simplest form is

\sqrt{\dfrac{576}{64} }=\dfrac{3}{1}

Step-by-step explanation:

Simplify:

\sqrt{\dfrac{576}{64} }

Now,

Prime Factorization of 576

576=2\times 288\\576=2\times 2\times 144\\576=2\times 2\times 2\times 72\\576=2\times 2\times 2\times 2\times 36\\576=2\times 2\times 2\times 2\times 2\times 18\\576=2\times 2\times 2\times 2\times 2\times 2\times 9\\576=2\times 2\times 2\times 2\times 2\times 2\times 3\times 3

Prime Factorization of 64

64=2\times 32\\64=2\times 2\times 16\\64=2\times 2\times 2\times 8\\64=2\times 2\times 2\times 2\times 4\\64=2\times 2\times 2\times 2\times 2\times 2

Now,

\sqrt{\dfrac{576}{64} }=\sqrt{\dfrac{2\times 2\times 2\times 2\times 2\times 2\times 3\times 3}{2\times 2\times 2\times 2\times 2\times 2} }\\ \sqrt{\dfrac{576}{64} }=\sqrt{\dfrac{3\times 3}{1}}\\\therefore \sqrt{\dfrac{576}{64} }=3

The Expression in simplest form is

\sqrt{\dfrac{576}{64} }=\dfrac{3}{1}

The length of an aquarium, which has the form of a rectangular solid, is equal to 5 decimeters, and the width is 4/5 the length.
Oksanka [162]

Answer:

Given the statement: The length of an aquarium, which has the form of a rectangular solid, is equal to 5 decimeters, and the width is 4/5 the length.

Since, aquarium is in the form of a rectangular solid.

Length of an aquarium(l) = 5 dm

Width of an aquarium(w)= \frac{4}{5}\times 5 = 4 dm

It is also given that when you put 40 liters of water into the aquarium, it was full to \frac{2}{3} its volume.

Volume of Rectangular solid(V) is given by;

V = l \times b \times h where l is the length , w is the width and h is the height of the rectangle respectively.

Volume(V) of an aquarium = \frac{3}{2} \times 40 = 60 liter.

Using volume formula to calculate the height(h);

60 = 5 \times 4 \times h

60 = 20h

Divide both sides by 20 we get;

h =  3 dm                      [ 1 liter = 1 cubic dm]

We have to find the what part of length makes up the height of the aquarium.

h = \frac{3}{5} l       where l = 5 dm

therefore, \frac{3}{5} part of the length makes up the height of the aquarium.

The blueprint of a concrete patio has a scale of 2 in. = 3 ft You want to find the dimensions of a new blueprint of the patio wi
LenKa [72]

Answer:

If\ old\ scale\ is\ taken:\ Length=45\ ft,\ Width=42\ ft\\\\If\ new\ scale\ is\ taken:\ Length=36\ ft,\ Width=33.6\ ft

Step-by-step explanation:

Older Scale:

2\ in=3\ ft\\\\\Rightarrow 1\ in=\frac{3}{2}\ ft\\\\Length=30\ in\\\\Length=30\times \frac{3}{2}\ ft\\\\Length=45\ ft\\\\Width=28\ in\\\\width=28\times \frac{3}{2}\ ft\\\\width=42\ ft

New scale:

4\ in=5\ ft\\\\\Rightarrow 1\ in=\frac{5}{4}\ ft\\\\Length=30\ in\\\\Length=30\times \frac{5}{4}\ ft\\\\Length=36\ ft\\\\Width=28\ in\\\\width=28\times \frac{5}{4}\ ft\\\\width=33.6\ ft

The following function is probability mass function. f left-parenthesis x right-parenthesis equals StartFraction 2x plus 1Over 2
lora16 [44]

Answer:

a) Mean  = 2.6

B) Variance = 9.2

Step-by-step explanation:

We are given the following probability mass function in the question:

F(x) = \dfrac{2x+1}{25}, x = 0,1,2,3,4

a) Mean of random variable

\mu = \displaystyle\sum x_iF(x_i)\\\\=0(\dfrac{1}{25}) + 1(\dfrac{2+1}{25}) + 2(\dfrac{4+1}{25}) + 3(\dfrac{6+1}{25}) + 4(\dfrac{8+1}{25})\\\\=\dfrac{3+10+21+36}{25} = \dfrac{70}{25} = 2.8

b) Variance of the random variable

\sigma^2 = \displaystyle\sum x_i^2F(x_i)\\\\=0^2(\dfrac{1}{25}) + 1^2(\dfrac{2+1}{25}) + 2^2(\dfrac{4+1}{25}) + 3^2(\dfrac{6+1}{25}) + 4^2(\dfrac{8+1}{25})\\\\=\dfrac{3+20+63+144}{25} = \dfrac{230}{25} = 9.2
