<h3>
P(call a person not from his neighborhood) = 
</h3>
Step-by-step explanation:
Here, the total number of contacts in the list if Bruce = 25 contacts
The total number of neighbors in the contact = 20 people
Now, let E: Event of calling a person from his neighborhood
So, P(E) = 
So, the probability of calling a person from his neighborhood is 
⇒P(E) =
Now,as we know: P(E) + P(not E) = 1
So, the probability of NOT calling a person from neighborhood
= 1 - probability of calling a person from his neighborhood
⇒P( not E) =
Hence, P(call a person not from his neighborhood) =
Answer: 448
Step-by-step explanation:
f(x) = (x + 7)² - 8
the equation of a quadratic in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
given the quadratic in standard form : y = ax² + bx + c ( a ≠ 0 )
then the x-coordinate of the vertex is
= - 
f(x) = x² + 14x + 41 is in standard form
with a = 1, b = 14 and c = 41
= - 
= - 7
substitute this value into the equation for y- coordinate
y = (- 7 )² + 14(- 7 ) + 41 = 49 - 98 + 41 = - 8
f(x) = (x + 7)² - 8 ← in vertex form
A slope of 3/2 passing through (-3,0) gives us slope intercept form of
y - 0 = (3/2) (x - -3)
y = (3/2) x + 9/2
That's a y intercect of 9/2
