1. Invoices are prepared by Shanty, Jenny and Sherry. A sample of 500 invoices are selected. Two hundred were prepared by Shanty, 120 by Jenny and 180 by Sherry. The error rates of Shanty, Jenny and Sherry were found to be 2%, 3% and 4% respectively. From the sample of 500 invoices, one invoices was selected. a. Sketch a Tree Diagram based on the information given in the question. b. Compute the probability that invoice contains error?

aye bru this a great thing your doin here.

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
