Jamie is conducting inventory at a public library, so they have to verify that each item from the catalog is in its correct loca

tion. At any given time, 97%, percent of the items are checked into the library (not checked out). Let B be the number of items that Jamie verifies to reach the first item that is checked out. Assume that each item's checked out status is independent.
Find the mean and standard deviation of B.

Given f(x) and g(x) = f(k⋅x), use the graph to determine the value of k<br>2<br>-2<br>1/2<br>-1/2
Umnica [9.8K]

Answer:

Step-by-step explanation:

Using the graph we can notice something

let's take the abscissa  -2 and -4

  • the ordinate that goes with -2 using g is 0
  • the ordinate that goes with  -4 using f is 0

so we can say that :

f(-4)=g(-2)

wait we khow that g(x)=f(k*x)

so x= -2 then let's replace it in the expression : f(k*x)

we get f(-4)=g(-2)=f[k*(-2)]

let's solve the equation: -2k = -4

                                               k = -4/-2

                                                k=2

so finally we get k=2

let's check :

from the graph we get :

  • f(-2)=2
  • g(-1)=2

we have (-1)*2 = -2

so it is true

I really need help. I need to go to sleep but I also need to finish this first plz help
WITCHER [35]
Since it doesn't give us a specific variable to use I'll just use y. and my phone doesn't have the less than or equal to sign so ill just say how to draw it i guess.
41. y (less than sign with line) 4.
42. y × (-7) > 42
43. y ÷3 - 5 (greater than sign with line) 11

and im not 100% sure on 44 so... anyway you probably know what the greater than or equal to sign and the less than or equal to sign are so. yeah hope it helped.
