The ratios 84/105 and 128/160 are proportional
<u>Solution:</u>
Given, two ratios are
and 
We have to give two different reasons to support the answer.
<em><u>Reason 1:</u></em>
Now, we know that, numerators and denominators should be proportional to be two fractions in proportion.

So numerators and denominators are in proportion, then given two fractions are proportion.
<em><u>Reason 2:</u></em>
Now, values of two fractions must be equal:

So, values of two fractions are equal, then they are in proportion.
Hence, the given two fractions are in proportion.
Answer:
This type of data is called Box and Whisker plots
Step-by-step explanation:
This type of data tells you the range of the data as well as the inner quartile range as it shows the minimum, maximum, median, and Q1 and Q3.
The function is all of the ordered pairs (dots/points) on the graph. The definition of a function is that all inputs (x values) have exactly one output (y value). Therefore, this is a function, and the x and y values have been plotted on this graph to more easily visualize the function for you.
Answer:
Blank 1: 0.12
Blank 2: 0.18
Step-by-step explanation:
Out of 50, there are 6 numbers that contain the digit 5, (5, 15, 25, 35, 45, 50)
so when you take 0.06 and multiply it by 2 (because you have to multiply 50 by 2 to get 100), you get 0.12.
For blank 2, there are 9 single digit numbers, (1, 2, 3, 4, 5, 6, 7, 8, and 9) equaling 0.09. Multiply that by 2 and you get 0.18.
Expanding the right side:-
5x - 4 = 5x - 15 + 11
5x - 4 = 5x - 4
left side = right side so there are infinitely many solutions
