3x+4y+6z=15 Solve for x.

aalyn [17]

Answer:

Step-by-step explanation:

<h3>Question:-</h3>

To solve for x

<h3>Equation:-</h3>

3x + 4y + 6z = 15

<h3>Solution:-</h3>

=> 3x + 4y + 6z = 15

[On subtracting both sides with 4y]

=> 3x + 4y + 6z - 4y = 15 - 4y

[On Simplification]

=> 3x + 6z = 15 - 4y

[On subtracting both sides with 6z]

=> 3x + 6z - 6z = 15 - 4y - 6z

[On Simplification]

=> 3x = 15 - 4y - 6z

[On dividing both sides with 3]

$= > \frac{3x}{3} = \frac{15 - 4y - 6z}{3}$

[On Simplification]

$= > x = 5 - \frac{4}{3} y - 2z \: (ans)$

A pharmaceutical company receives large shipments of aspirin tablets. the acceptance sampling plan is to randomly select and tes

Mrac [35]

For a really large shipment, and a relatively high "success" rate (i.e. selecting the defectives), we may assume that sampling without replacement does not change the probability, hence binomial distribution may be used, with which
$P(x)=C(n,x)p^x(1-p)^{n-x}$
where $C(n,x)=\frac{n!}{x!(n-x)!}$ and
n=26, p=0.44

In the given case, n=26, we need
P(0)+P(1)
$=C(26,0)0.44^0(1-0.44)^{26-0}+C(26,1)0.44^1(1-0.44)^{26-1}$
$=0.0000002837+0.0000057950$
=0.000006080
with a 4% error compared with the exact answer (for a population of 5000), or 0.42% error if the population is 50,000, as follows

Exact solution by hypergeometric distribution taking into account of selection without replacement, assuming a population of only 5000
P(x)=C(A,a)C(B,b)/(C(A+B,a+b)
a={0,1}
b={26,25}
A={2200,2199}
B={2800,2800}

P(0)+P(1)
=C(2200,0)C(2800,26)/C(5000,26)+C(2200,1)C(2800,25)/C(5000,26)
=0.0000002695+0.0000055557
=0.00058252

Similarly, for a 50000 population,
=C(2200,0)C(2800,26)/C(5000,26)+C(2200,1)C(2800,25)/C(5000,26)
=0.0000060539
