B / 2 siblings

Step-by-step explanation:

edge 22 , hope it helped

The mean number of siblings for the population rounded to the nearest unit is 2.

Mean is defined as the ratio of the sum of the number of the data sets to the total number of the data.

Gien data is:-

3, 2, 0, 1, 0, 2, 3, 4, 1, 2, 2, 1

The mean will be calculated as:-

Mean = ( 3 + 2 + 0 + 1 + 0 + 2 + 3 + 4 + 1 + 2 + 2 + 1 ) / 12

Mean  = 21  /  12

Mean = 1.75

Mean = 2

Therefore the mean number of siblings for the population rounded to the nearest unit is 2.

Answer:

0.6 multiply by 5250

its 3168

The Conversion of 0.6 miles is equal to 3,168 feet.

To convert 0.6 miles to feet, we need to use the conversion factor that 1 mile is equal to 5,280 feet.

As, 1 mile= 5280 feet

So, we can multiply 0.6 miles by the conversion factor:

= 0.6 miles x 5,280 feet/mile

= 3,168 feet

Therefore, 0.6 miles is equal to 3,168 feet.

Answer:

False

Step-by-step explanation:

8^3=512

512 divded by 2=256

256=250

This is false.

Hence this equation is false

Answer:

False

Step-by-step explanation:

Given the following question:

[tex]8^3[/tex]

To find if the solution is true, we must first convert the exponent into a whole number by multiplying three by itself, three times since three is the exponent.

[tex]8^3[/tex]
[tex]8^3=8\times8\times8[/tex]
[tex]8\times8=64[/tex]
[tex]64\times8=512[/tex]

Now divide:
[tex]512[/tex]
[tex]512\div2=256[/tex]
[tex]=256[/tex]

Which means the following statement 8^3 divided by 2 = 250 is indeed "false."

Answer:

Step-by-step explanation:

Answer:

y = -5x - 1

Step-by-step explanation:

To find the function rule:

We use the equation "y = mx + b"

Function rule: What we need to do to "x" to get "y"

Look at the x-values. You need to know if they are going up by one or if they are skipping.  In this case, they are going up by one.

Next, look at the y-values and see how they are changing. The y-values in this table are going down by 5 every time, which means we will multiply each "x" by "-5".

After that, pick the first 'x" in the table and multiply it by "-5", then figure out what you need to do to make it equal the y-value.

You need to subtract 1. This means the rule is "y = -5x - 1"

To check if this is correct, we do the following:

y = -5x - 1

Substitute the first x and y values into the equation

9 = -5(-2) - 1

Multiply -5 and -2

9 = 10 - 1

Subtract 1 from 10

9 = 9

True

Let's check the second equation

y = -5x - 1

Substitute the x and y values in the second column of the table

4 = -5(-1) - 1

Multiply -5 and -1

4 = 5 - 1

Subtract 1 from 5

4 = 4

True

So, the function rule "y = -5x - 1" is true

Step-by-step explanation:

Hello.

We have a point that the line passes through and its slope.

Let's write the equation in Point-Slope Form:

y-y₁=m(x-x₁)

In this case,

y₁=2

m=[tex]\displaystyle\frac{1}{2}[/tex]

x₁=4

Plug in the values:

[tex]\mathrm{y-2=\displaystyle\frac{1}{2} (x-4)}[/tex]

This is point-slope form. Now, what about Slope-Intercept?

First, we should distribute [tex]\displaystyle\frac{1}{2}[/tex]:

Answer:

D'(2,0), E'(3,3), F'(6,4)

Step-by-step explanation:

The matrix transformation of ΔDEF for a translation 1 unit right and 2 units down for the coordinates D(3, −2), E(4, 1), and F(7, 2) will be D'(2,0), E'(3,3), F'(6,4).

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

It is given that, the coordinates of ΔDEF will be D(3, −2), E(4, 1), and F(7, 2).

For a translation 1 unit right and 2 units down we got the coordinates as D'(2,0), E'(3,3), and F'(6,4).

Thus, the matrix transformation of ΔDEF for a translation 1 unit right and 2 units down for the coordinates D(3, −2), E(4, 1), and F(7, 2) will be D'(2,0), E'(3,3), F'(6,4).

Answer:

Part A

Cone

[tex]\mathsf{volume \ of \ a \ cone=\dfrac13\pi r^2h}[/tex]

(where r is the radius and h is the height)

Given:

[tex]\implies \mathsf{volume \ of \ the \ cone=\dfrac13\pi \cdot a^2\cdot2a=\dfrac23\pi a^3}[/tex]

Hemisphere

[tex]\mathsf{volume \ of \ a \ sphere=\dfrac43\pi r^3}[/tex]

[tex]\implies \mathsf{volume \ of \ a \ hemisphere=\dfrac12 \cdot\dfrac43\pi r^3=\dfrac23\pi r^3}[/tex]

Given

[tex]\implies \mathsf{volume \ of \ the \ hemisphere=\dfrac23\pi a^3}[/tex]

Therefore

volume of cone with radius a = volume of hemisphere with radius a

Part B

[tex]6.82^2\times\sqrt[3]{0.005}[/tex]

Take log of base 10:

[tex]\implies \log_{10}(6.82^2\times\sqrt[3]{0.005})[/tex]

Using log law [tex]\log(a \times b)=\log a+\log b[/tex]:

[tex]\implies \log_{10}(6.82^2)+\log_{10}(\sqrt[3]{0.005})[/tex]

Using low law [tex]\log(a^b)=b \log a[/tex]

[tex]\implies 2\log_{10}(6.82)+\dfrac13\log_{10}(0.005)[/tex]

Log tables

The characteristic of the logarithm of a number is the exponent of 10 in its scientific notation.

The mantissa is found using the log tables and is always prefixed by a decimal point.

The row is the first two non-zero digits of the number, and the column is the 3rd digit of the number

Use the log tables to find [tex]\log_{10}(6.82)[/tex]:

6.82 = 6.82 × 10⁰

⇒ characteristic = 0

log table:  row 68, column 2 ⇒ mantissa 8338 ⇒ 0.8338

characteristic + mantissa = 0 + 0.8338 = 0.8338

Therefore, [tex]\log_{10}(6.82)=0.8338[/tex]

Use the log tables to find [tex]\log_{10}(0.005)[/tex]:

[tex]0.005 = 5.0 \times 10^{-3}[/tex]

⇒ characteristic = -3

log table: row 50, column 0 ⇒ mantissa 6990 ⇒ 0.6990

characteristic  + mantissa = -3 + 0.6990 = -2.301

Therefore, [tex]\log_{10}(0.005)=-2.301[/tex]

Therefore,

[tex]2\log_{10}(6.82)+\dfrac13\log_{10}(0.005)[/tex]

[tex]\implies 2\cdot0.8338 + \dfrac13 \cdot -2.301[/tex]

[tex]\implies 1.6676 - 0.767[/tex]

[tex]\implies 0.9006[/tex]

Therefore,

[tex]\log_{10}(6.82^2\times\sqrt[3]{0.005})=0.9006[/tex]

Using [tex]\log_{a}b=c \implies a^c=b[/tex]

[tex]\implies 6.82^2\times\sqrt[3]{0.005}=10^{0.9006}[/tex]

[tex]\implies 6.82^2\times\sqrt[3]{0.005}=7.954[/tex]

given for cone:

volume of cone:

[tex]\sf \rightarrow \dfrac{1}{3} \pi r^2h[/tex]

[tex]\sf \rightarrow \dfrac{1}{3} \pi (a)^2(2a)[/tex]

[tex]\sf \rightarrow \dfrac{2\pi a^3}{3}[/tex]

no metal wasted means no volume wasted while melting so volume: same.

volume of hemisphere:

[tex]\hookrightarrow \sf \dfrac{2}{3} \pi r^3[/tex]

This is equal to the volume of cone.

[tex]\hookrightarrow \sf \dfrac{2}{3} \pi r^3 = \dfrac{2\pi a^3}{3}[/tex]

[tex]\hookrightarrow \sf a^3 = r^3[/tex]

[tex]\hookrightarrow \sf a = r[/tex]

Therefore shown that radius of cone is similar to radius of hemisphere.
