The correct answer will be option C. Mode.

Mode is the most frequently occurring value of the data. From the above line plot we can see that the most frequently occurring value is 3. Even if 10 is removed from the line plot, 3 will still be the most frequently occurring value and will be the mode of the data. Thus removing 10 does not changes the mode of the data at all.

The mean will obviously be changed. The range is difference of maximum and minimum value. 10 was initially the maximum value. If 10 is removed, the maximum value will change and so does the Range of the data. Removing 10 changes the total number of data values, so the position of median also changes which changes the value of Median.

Therefore, the correct answer to this question is option C

Julie wrote the rate 108$ in 6 weeks as a unit rate.Find her mistake and correct it.
puteri [66]

Unit rate has 1 in the denominator. $108 in 6 weeks has 6 weeks as the denominator, which isn't one of anything (unless we treat 6 weeks to be a unit). What Julie probably intended as the unit rate was $108/6 weeks = $18 / week.

When the area in square units of an expanding circle is increasing twice as fast as its radius in linear units
alexira [117]

Answer:

r=1/π

Step-by-step explanation:

Area of the circle is defined as:

Area = πr²

Derivating both sides

\frac{dA}{dr}=2πr

\frac{dA}{dt}  =  \frac{dA}{dr} x \frac{dr}{dt}  =  2πr\frac{dr}{dt}

If area of an expanding circle is increasing twice as fast as its radius in linear units. then we have : \frac{dA}{dt}  =2\frac{dr}{dt}

Therefore,

2πr \frac{dr}{dt}  =  2  \frac{dr}{dt}

r=1/π

Cube 1 has a volume of c3. The side lengths of Cube 2 are three units longer than those of Cube 1. What is the volume of Cube 2?
kotegsom [21]
Volume of a Cube:  
<span>Since all of the edges of a cube are of equal length, there is no need to differentiate between the length, width and height.  The volume of a cube is determined by multiplying the length of three edges of the cube.  Let "a" define the length of an edge of the cube.  

Then the volume formula is defined as:</span>
V = a<span> × </span>a<span> × </span>a
<span>This formula is also written as V = a³<span>.

If a = 5 feet, then the volume is found like this:</span></span>
V = (5)³ = 5<span> × </span>5<span> × </span>5 = 125:  Since each value is a measurement of feet, the volume is therefore 125 cubic feet. 

Example 1:<span> Find the volume of a solid cube shape box whose side is 13m.</span>
Solution: 
<span>Given that: side a = 3m
Volume of the cube is therefore:</span>
V = a³
V = 13³
<span>V = 2197 m3</span>

Example 2:<span><span> Find the measure of volume of a cube for the given side length is 20 inches?</span>
<span>Solution:</span> 
<span>Given that: Side a = 20 inches
Volume of the cube is therefore:</span></span>
V = a³
V = 20³
<span>V = 8000 in3</span>
<span>Therefore, volume of a cube is 8000 in3.

</span>
Example 3:<span> Find the volume of a cube for the given side length 12.5 meter?</span>
Solution: 
Given that: Side a = 12.5 m
V = a³
V = 12.5³
<span>V = 1953.125 m3</span>
<span><span>Therefore, the volume of the cube is 1953.125 cubic meter.</span>
