Answer:
Step-by-step explanation:
Given that the proportion of murders with firearm is 79.2 %
Each murder is independent and there are two outcomes either with fire arm or without fire arm.
Hence X no of murders with fire arm is binomial with n = 200 and p = 0.792
q=1-0.792 = 0.208
a) Expected value of x = np
b) P(X=173) = 0.002289
Since probability is very low it can be concluded it would be unusual to observe 173 murders by firearm in a random sample of 200 murders
The solution of the given system of equation is x = -3 and y = 4 respectively.
<h3>What is a system of linear equations?</h3>
A system of linear equations can be defined as a number of equations needed to solve the equations. For n number of variables n number of equations are required.
The given system of equations is as,
y = 4x + 16 (1)
y = −2x − 2 (2)
In order to solve them, substitute equation (2) into (1) as follows,
4x + 16 = −2x − 2
=> 4x + 2x = -2 - 16
=> 6x = -18
=> x = -3
Then, y = -2 × -3 - 2 = 4
Hence, the solution of the given system of equation is x = -3 and y = 4.

Answer:
Cos<42 sin<16 :)
Step-by-step explanation:
The answer is 3/5 simplified.
Reasoning:
There are 6 solid white and solid black marbles combined.
There are total of 10 marbles.
Of the 10 marbles, you are 6/10 times likely to pull one of the solid black or white marbles.
Simplify 6/10 by dividing it by a number they both share (2) to get the answer of 3/5.
