Solve for y
y+1=-7x-7
minus 1 both sides
y-7x-8

In slope intercept form this would be equal to y=-7x-8. (remember the 7 is negative!)

Answer:

x=10.7

Step-by-step explanation:

Our proportion is

x/4=8/3

We can cross multiply to solve.

This is where you multiply one fraction's numerator with the other fraction's denominator and vice versa.

x*3=4*8

3x=32

Divide both sides by 3.

x=10.6666666667

Round.

x=10.7

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

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.
