The given statement is False.
What is median?
'In statistics and probability theory, the median is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution.'
According to the given problem,
Median = 6
Total count = 11
Range = 0
Now, range is the difference between the highest value and the lowest value.
Since, the median is 6, the highest number must be greater than 6. This would not have been possible if the lowest value was 0. If the lowest count had been 0, then the highest count had to be 4.
Hence, we can conclude, the fewest cars sold cannot be 0.

Given:
Consider the below figure attached with this question.
Perimeter of triangle ABC is 13 cm.
Triangle ABC is dilated to create the triangle A'B'C'.
To find:
The perimeter of triangle A'B'C'.
Solution:
We know that, dilated figures are similar.
[tex]\text{Scale factor}=\dfrac{\text{Side of image}}{\text{Corresponding side of preimage}}[/tex]
[tex]\text{Scale factor}=\dfrac{OB'}{OB}[/tex]
[tex]\text{Scale factor}=\dfrac{5+15}{5}[/tex]
[tex]\text{Scale factor}=\dfrac{20}{5}[/tex]
[tex]\text{Scale factor}=4[/tex]
Perimeters of similar figure is proportional to the corresponding sides of that figure or equal to the scale factor.
[tex]\dfrac{\text{Perimeter of }\Delta A'B'C'}{\text{Perimeter of }\Delta ABC}=\text{Scale factor}[/tex]
[tex]\dfrac{\text{Perimeter of }\Delta A'B'C'}{13}=4[/tex]
Multiply both sides by 13.
[tex]\text{Perimeter of }\Delta A'B'C'=13\times 4[/tex]
[tex]\text{Perimeter of }\Delta A'B'C'=52[/tex]
Therefore, the perimeter of triangle A'B'C' is 52 cm.

In the Equation 4x + 3y = 7 which value is a coefficient
The co-efficient value is "4 and 3".
Coefficient equation:[tex]\to 4x + 3y = 7[/tex]
Using the standard form to calculate value:
[tex]\to ax+bx+c=0[/tex]
compare the above value:
[tex]\to 4x + 3y -7=0\\\\\to ax + by +c=0\\\\[/tex]
co-efficient of x = 4
co-efficient of y = 3
constant term= -7
Therefore, the final answer is "4,3".

What is the equation of a parallel line to y = -5x + 2 that passes through the point (-1, 4)?
Answer:
The equation of the Parallel line passes through the point (-1,4) is
y = -5 x -1
Step-by-step explanation:
Explanation:-
Given the equation of the line y = -5 x + 2
Given point (-1 , 4 )
The equation of the parallel line of a given line is 5x + y +k=0 ...(i)
The equation (i) passes through the point (-1,4)
5(-1)+4+k=0
-5 +4 +k =0
-1 + k = 0
k = 1
The equation of the Parallel line passes through the point (-1,4) is
y = -5 x -1
If you draw a card with a value of four or less from a standard deck of cards, I will pay you $162. If not, you pay me $45. (Aces are considered the highest card in the deck.) Find the expected value of the proposition. Round your answer to two decimal places. Losses must be expressed as negative values.
Answer:
the expected value of the proposition is 2.77
Step-by-step explanation:
The computation of the expected value of the proposition
= 162p - 45(1 - p)
= 162 × 12 ÷ 52 - 45 × (1 - 12 ÷ 52)
= 2.77
Hence, the expected value of the proposition is 2.77
So we simply do the above calculation so that the expected value could come

The table shows the proportional relationship y=kx. Which is the unit rate,k?
Pls help
Answer:
[tex]k=\frac{4}{7}[/tex]
Step-by-step explanation:
The equation [tex]y=kx[/tex] represents a proportional relationship that always passes through the origin. Excluding of the origin, you can plug any [tex](x,y)[/tex] coordinate into this function to get [tex]k[/tex].
Using the first coordinate, we have:
[tex]4=k(7),\\k=\frac{4}{7}[/tex]
Verify that [tex]y=kx[/tex] works for the other coordinates [tex]\checkmark[/tex]
Thus, the value of constant [tex]k[/tex] is [tex]\fbox{$\frac{4}{7}$}[/tex].

What percent of 40 is22 ?
Answer: 181.82
Explanation:
Step 1: We make the assumption that 22 is 100% since it is our output value.
Step 2: We next represent the value we seek with x.
Step 3: From step 1, it follows that 100%=22.
Step 4: In the same vein, x%=40.
Step 5: This gives us a pair of simple equations:
100%=22(1).
x%=40(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the left hand side of both equations have the same unit (%); we have
100 percent/X percent = 22/40
Step 7: Taking the inverse (or reciprocal) of both sides yields
100 percent/X percent = 40/22
X = 181.82%
Therefore, 40 is 181.82% of 22.
Hope this helps^-^.
