Answer:
Column 1(X) Column 2(mean - X)
125 -13
137 -1
138 0
145 7
145 7
Mean = 138
Mean Absolute Deviation : 5.6
We can set up a proportion since we know the ratio between the # of purple marbles and the # of green marbles.
A ratio is a way to compare two different values: for every 8 purple marbles there are 5 green marbles
<h2>
</h2><h2 /><h2>when we cross multiply, we get 5p = 240 </h2><h2>we divide both sides by 5 to isolate the variable </h2><h2 /><h3><u>There are 48 purple marbles </u></h3>
Discontinuity: x=-4
Zero: x=3/2
Answer:
425733.32
Step-by-step explanation:
3%= 12772×100÷x
3x= 12772×100
x=425733.34
Answer:
x = 4
Step-by-step explanation:
as it is parallelogram opposite sides are equal
so14x -7= 10x-9
14x-7+9=10x
14x -16 = 10x
14x -10x = 16
4x =16
x = 16/4
x = 4
also u can put x = 4 in both expressions and u will get answer of both 49
