Question attached plz answer

Answer:

x = - 2.5

Step-by-step explanation:

Given that the sketch represents

y = x² + bx + c

The graph crosses the y- axis at (0 , - 14), thus c = - 14

y = x² + bx - 14

Given the graph crosses the x- axis at (2, 0), then

0 = 2² + 2b - 14

0 = 4 + 2b - 14 = 2b - 10 ( add 10 to both sides )

10 = 2b ( divide both sides by 2 )

b = 5

y = x² + 5x - 14 ← represents the graph

let y = 0 , then

x² + 5x - 14 = 0 ← in standard form

(x + 7)(x - 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 7 = 0 ⇒ x = - 7

x - 2 = 0 ⇒ x = 2

The x- intercepts are x = - 7 and x = 2

The vertex lies on the axis of symmetry which is midway between the x- intercepts, thus

the x- coordinate of the turning point is \frac{-7+2}{2} = \frac{-5}{2} = - 2.5

Probability is a measure of how likely an event is to occur. write the probability of the following statements:
attashe74 [19]

Step-by-step explanation:

This is a probability related question, let the event be E

We know that the likelihood of an event happening is given as

Pr(E)=1

if an event will not occur the probability is

Pr(E)=0

a. This event is impossible: Pr(E)=0

b.This event will occur more often than not, but is not extremely likely:  

Pr(E)=0<E>0.5

c.This event is extremely unlikely, but it will occur once in a while in a long sequence of trials:

Pr(E)=0<E<0.5

d.This event will occur for sure: Pr(E)=0
