What is the product of 7/16 and -6/13 I will make you the brainlest

mr_godi [17]

Answer:

$\frac{7}{16} *\frac{-6}{13} = \frac{-42}{208}$

Step-by-step explanation:

$\frac{7}{16} *\frac{-6}{13} = \frac{-42}{208}$ . First multiply 7*-6=-42.

Then do 16*13=208.

Simplify by dividing both by 2.

You get $\frac{-42}{208}=\frac{-21}{104}$ .

Your final simplified answer is $\frac{-21}{104}$

I hope this helps!

Solve for n.<br>--42 – 6n = -30

rodikova [14]

N=-2
Add 42 to both sides to get -6n=12
Divide both sides by -6

A shipment of 50 precision parts including 4 that are defective is sent to an assembly plant. The quality control division selec

natali 33 [55]

Answer:

0.3968 = 39.68% probability this shipment passes inspection.

Step-by-step explanation:

The parts are chosen without replacement, which means that the hypergeometric distribution is used to solve this question.

Hypergeometric distribution:

The probability of x successes is given by the following formula:

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}$

In which:

x is the number of successes.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In this question:

50 parts means that $N = 50$

4 defective means that $k = 4$

10 are chosen, which means that $n = 10$

What is the probability this shipment passes inspection?

Probability that none is defective, so:

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}$

$P(X = 0) = h(0,50,10,4) = \frac{C_{4,0}*C_{46,10}}{C_{50,10}} = 0.3968$

0.3968 = 39.68% probability this shipment passes inspection.
