Answer:

The most common score is 89.

Step-by-step explanation:

The dot plot is attached to this question with frequency on the y-axis and the test scores on the x-axis.

One canned juice drink is 15% orange juice another is 10% orange juice how many liters of each should be mixed together in order
vfiekz [6]
\bf \begin{array}{lccclll}&#10;&quantity(L)&concentration&&#10;\begin{array}{llll}&#10;concentrated\\&#10;quantity&#10;\end{array}\\&#10;&-----&-------&-------\\&#10;\textit{15\% juice}&x&0.15&0.15x\\&#10;\textit{10\% juice}&y&0.10&0.10y\\&#10;-----&-----&-----&-----\\&#10;mixture&5&0.14&(5)(0.14)&#10;\end{array}

whatever the amounts of "x" and "y" are, they must add up to 5Liters
thus x + y = 5

and whatever the concentrated quantity is in each, they must add up to (5)(0.14)

notice, that we use the decimal notation for the amount of juice concentration, that is, 15% is just 15/100 or 0.15, and 14% is just 14/100 or 0.14 and so on, recall that "whatever% of something" is just (whatever/100)*something

thus    \bf \begin{cases}&#10;x+y=5\implies \boxed{y}=5-x\\\\&#10;0.15x+0.10y=(5)(0.14)\\&#10;----------\\&#10;0.15x+0.10\left(\boxed{5-x}  \right)=(5)(0.14)&#10;\end{cases}

solve for "x", to see how much of the 15% juice will be needed

what about "y"?  well, y = 5 - x
