Answer: less than 25%
Step-by-step explanation:
The box plot can be read as follows:
The first black dot is the minimum value.
The first half of the rectangle is the lower quartile.
The line that separates the two rectangles is the median.
The second half of the rectangle is the upper quartile
The final point is the maximum.
Knowing that each quartile represents about the 25% of the elements for the set, we can see that both lower and upper quartile (and the 25% of the elements that come after the upper quartile) cost more than $45.
Then we know that at least the (25% + 25% + 25%) = 75% of the cards in the collection cost more than $45.
And we also have elements that are not in the lower quartile that cost more than $45, but we can not determine the percentage that they represent.
So we can only conclude that more than the 75% of the collection costs more than $45.
Now we want to know the percentage of the baseball cards valued at less than $45.
So if more than 75% is valued at more than $45.
Then less than 25% is valued at less than $25.
F(x)=x+c, where c is an arbitrary constant.
if c is positive then translation above
if c is negative then translation down
reflection of f(x)=x^2 across x-axis then
f(x)=-x^2
Answer:
PR = 5 because LP + PR = LR according to the Segment Addition Postulate, and 7 + 5 = 12 using substitution
Step-by-step explanation:
The naming of the segments suggests that point P is between L and R, so that ...
LP + PR = LR
This corresponds to the last choice.
_____
<em>Comments on the alternate interpretation</em>
On the other hand, if point L is between P and R, then the segments are PL and LR. The Segment Addition Postulate would tell you that ...
PL + LR = PR
The Reflexive Property of Congruence would tell you that PL = LP. The Substitution Property would tell you LP can be substituted into this equation, making it ...
LP + LR = PR
and by the commutative property, ...
LR + LP = PR.
Multiple properties of addition and congruence are involved with this interpretation, which more or less matches the third choice. That is, the simple explanation of answer choice 3, by itself, is insufficient to explain why the length of PR should be considered to be 19, not 5.
The answer is B. She sells each orange for $0.50 and the question is asking for the total amount of money she will make by selling a certain amount of oranges. t represents the total so the equation will to equal to t. c is the number of oranges she will sell so c multiplied by $0.50 will give the total amount of money she will make.
