Consider the following data set: 9,8,8,2,0,0 find the median

The average density of the material in intergalactic space is approximately 2.5 × 10–27 kg/m3. what is the volume of a lead samp

Lesechka [4]

Answer:

e. $1.8\times 10^{-6}m^3$

Step-by-step explanation:

It is given that,

The density of intergalactic space material is $2.5 \times 10^{-27}$ kg per cubic meter.

And the volume of intergalactic space material is $8.0\times 10^{24} m^3$

So the mass of that much intergalactic space material is,

$m= \rho\times v$ , where 'm' is the mass, and 'v' is the volume.

Putting the values we get,

$m=2.5 \times 10^{-27}\times 8.0 \times 10^{24}$

$m=20\times 10^{(-27+24)}=20\times 10^{-3} kg$

It is also given that the mass of lead is the same as the mass of the intergalactic space material. Therefore, the mass of lead is $20 \times 10^{-3}=2 \times 10^{-2}kg$

So the volume of lead is,

$v=\frac{m}{\rho} =\frac{2 \times 10^{-2}}{11300} = 0.00000177 m^3$

$v=1.77 \times 10^{-6}=1.8\times 10^{-6}m^3$

So the volume of lead is $v=1.8\times 10^{-6}m^3$ .

A rectangle has an area of 120 square cm. Its length and width are whole numbers. List the possible dimensions of the rectangle.

Nadusha1986 [10]

Answer: kindly check explanation

Step-by-step explanation:

Given that:

Area of rectangle = 120 cm²

Assume ; Length and width are whole numbers

Possible dimension of the rectangle will be :

Area of a rectangle = Length × width

Area = 120cm²

Possible dimensions :

80cm by 1 cm

40cm by 2cm

20cm by 4cm

10cm by 8cm

5cm by 16cm

Possibility which gives the smallest perimeter :

Dimension = 10cm by 8cm

Perimeter of Rectangle = 2(length + width)

Perimeter of Rectangle :

= 2(10 + 8)cm

= 2(18)cm

= 36cm

Does this table represent a function? Why or why not?<br><br> Answers above

Mashutka [201]

Answer:

No, because a x-value repeats.

Step-by-step explanation:

A function has x-values that correspond to exactly one y-value. In the given table, <u>the number '5' appears twice as an x-value</u>. This means that the relation is not a function, "because one x-value corresponds to two different y-values."
