Answer:
the second paragraph describes better the graph
Step-by-step explanation:
First of all, the rank of the scale is too big for the graph. Water boiles at 100°C so extend it till the 200°C is unnecessary.
The y-axis scale is wrong because the celcius degree component of the graph´s points have a value within 50 and 90. Considering that one point of the graph´s scale is equal to 50°C, the hole set of points will be drawn between two point of the graph´s scale.
The x-scale is correct because the minutes of the points have a value within 0 and 4. The scale separates well the points and the rank is appropiate for the datums
We should do the whole math calculation, but for ease, we know that the percentage contained within 2 std deviations of a normal distribution is:
= 2(13.6) + 2(34.1)
= 95.4%
Total capacity (in litres)
=(x-2) + (x) + (x+2) + (x+4) group like terms
=4x-2+0+2+4
=4x+4 L.
Answer:
-6
Step-by-step explanation:
3(2y+5)=-21
2y+5=-21/3
2y+5=-7
2y=-7-5
2y=-12
y=-12/2
y=-6
The answer is: 63.1538461538461538 ; (round to: 63.154) .
_____________________________________________________
130/100 * n = 82.1 ; Solve for "n" ;
<span>_________________________________________
</span>(1.3) n = 82.1 ;
n = 82.1 / 1.3 ;
n = 82.1 / 1.3 = 63.1538461538461538 ; round to 63.154 .
