Step-by-step explanation:
Hey user☺☺
Option a is correct
Because the graph has only one solution.
As the graph touches the x-axis at one point that means that it will have only one solution for x. But we know that a quadratic equation has two solutions. So the graph will have two equal solution and therefore the discriminant will be 0.
Hope this will help☺☺
Your answer should be 71. :)
In 2005, 23 is in the second deviation
19 22 25 28 31 33 35
In 1965, 23 is in the third deviation.
12 14 16 18 20 22 24
<span>By the way, 13.5% range from 22 to 25 in 2005, while 2.1% range from 22 to 24 in 1965</span>
