Question 10 The graph below shows a quadratic function of the form y= ax2+box+c
Which statements about this graph are true? Choose ALL that are correct
The function represented in this graph has a zero of 2
B
The "a" coefficient of the equation represented in this graph is negative.
This graph has two x-intercepts,
D
This araph has a vertex of (-1.61)

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25

homozygous. one is homozygous, while two is heterozygous.

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
