Solve: 6(t-3) = 2(9 - 2t)<br> T=
Bogdan [553]

6(t-3)=2(9-2t)=

We move all terms to the left:

6(t-3)-(2(9-2t))=0

We add all the numbers together, and all the variables

6(t-3)-(2(-2t+9))=0

We multiply parentheses

6t-(2(-2t+9))-18=0

We calculate terms in parentheses: -(2(-2t+9)), so:

2(-2t+9)

We multiply parentheses

-4t+18

Back to the equation:

-(-4t+18)

We get rid of parentheses

6t+4t-18-18=0

We add all the numbers together, and all the variables

10t-36=0

We move all terms containing t to the left, all other terms to the right

10t=36

t=36/10

<h2>t=3+3/5</h2>

In one method of a procedure called acceptance sampling, a sample of items is randomly selected without replacement and the enti
jekas [21]

Answer:

X \sim Hyp (N = 810, M=102, n=4)

P(X=0) = \frac{(102C0)(810-102 C 4-0)}{810C4}  

And solving we got:

P(X=0)= \frac{(102C0) (708C4)}{810C4} = 0.583

So then for the problem given the probability that the entire bath will be accepted (none is defective among the 4) is 0.583

Step-by-step explanation:

For this case we can model the variable of interest with the hypergeometric distribution. And with the info given we can do this:

X \sim Hyp (N = 810, M=102, n=4)

P(X=k)= \frac{(MCk)(N-M C n-k)}{NCn}  

Where N is the population size, M is the number of success states in the population, n is the number of draws, k is the number of observed successes  

And for this case we want to find the probability that none of the scales selected would be defective so we want to find this:

P(X=0)

And using the probability mass function we got:

P(X=0) = \frac{(102C0)(810-102 C 4-0)}{810C4}  

And solving we got:

P(X=0)= \frac{(102C0) (708C4)}{810C4} = 0.583

So then for the problem given the probability that the entire bath will be accepted (none is defective among the 4) is 0.583

Parent Functions
jekas [21]

The graph of the parent function is given below;

<h3>What is Function?</h3>

The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

Here, the given function is;

         1, if -1<x≤0

f(x) = 2, if 0<x≤1

          3, if 1<x≤2

Now, the graph of given function is given below.
