Sample = 75 printers, Printers used by small businesses = 15

p(15) = 15/75 = 0.2

At 90% limit, Z =1.64

Limit of proportion of printers used by small business = p +/- Z Sqrt [p(1-p)/n]

=0.2 +/- 1.64 * Sqrt [0.2(1-0.2)/75] = 0.2 +/- 0.0757

Limit of proportion => (0.2-0.0757) to (0.2+0.0757) => 0.1243 to 0.2757 or 12.43% to 27.57%

Pleaseeeeee help with math. i’ve gotten no help today. explantion needed!!
Reptile [31]

Answer:

Exactly two distinct zeros

Step-by-step explanation:

y = 2(x-1) (x + 4)

Plug y = 0

0 = 2(x-1) (x + 4)

0/2 = (x-1) (x + 4)

(x-1) (x + 4) = 0

(x-1) = 0 or (x + 4)= 0

x = 1 or x = - 4

Here, x has two distinct roots, therefore given quadratic relation has Exactly two distinct zeros.

I have no idea how to graph g(x)..or why f(x) is relevant..... Steps would be helpful!! I got a final twomorrow ;-;​
SSSSS [86.1K]

When you derive a function from another using the transformation

g(x) = f(x+k)

you're translating the graph of the parent function f(x) horizontally.

More specifically, you translate the graph k units to the left if k is positive, k units to the right if k in negative.

So, starting from the graph of f(x), you have that the graph of

g(x) = f(x+3)

is the same graph of f(x), but shifted 3 units to the left.
