Answer: 6
Step-by-step explanation:
since they are both negative the answer is positve and the you divide
Answer:
TRUE
Step-by-step explanation:
A complex number is represented as z = x + iy
Given the complex number -5i, this can also be written as;
z = 0-5i
Get the modulus
|z| = √0²+(-5)²
|z| = √25
|z| = 5
Get the argument
theta = arctan(y/x)
theta = arctan(-5/0)
theta = arctan(-∞)
theta = -90degrees
Since tan is negative in the 2nd and fourth quadrant
in the fourth quadrant, theta - 360 - 90
theta = 270 degrees
Express in polar form;
z = |z|(cos theta + i sintheta)
z = 5(cos270°+ison270°)
Hence the statement given is TRUE
Answer:
0.3830,0.6170
Step-by-step explanation:
Given that a process for manufacturing an electronic component yields items of which 1% are defective.
n =100 and p = 0.01
Here X no of defectives is binomial since independence and two outcomes.
Approximation to normal would be
X is N(
X is N(1,0.995)
a) the probability that the process continues given the sampling plan described
=
(with continuity correction)
=
b) the probability that the process continues even if the process has gone bad (i.e., if the frequency of defective components has shifted to 5.0% defective)
1-0.3830
=0.6170
