Answer:

See below

Step-by-step explanation:

32. w + 5 = -20

w = -20 - 5

w = - 25

33. x - 17 = -32

x = -32 + 17

x = - 15

34. t + 7.2 = 1.65

t = 1.65 - 7.2

t = - 5.55

35. -0.4 = g - 4.9

g = - 0.4 + 4.9

g = 4.5

36. y - 2/5 = 1 3/5

y = 1 3/5 + 2/5

y = 1 5/5 or 2

37. -5 1/6 = 2 1/3 + p

p = - 5 1/6 - 2 1/3 convert 1/3 to x/6 for a common denominator

1/3 converts to 2/6

p = -5 1/6 - 2 2/6

p = - 7 3/6 or - 7 1/2

38. You were given that

Simone = $65.35 + Dan

Simone = Carly - 37.50

Carly = 127.75

So Simone = 127.75 - 37.50 = 90.25

Simone = 65.35 + Dan or Dan = Simone - 65.35

Dan = 90.25 - 65.35 = 24.90

Write an expression for the lengths of the rectangle in terms

Snowcat [4.5K]

Answer:

l = A/w

Step-by-step explanation:

Let 'A' equal area. If the formula for the area of a rectangle is A = lw, you need to get 'h' alone. Divide 'h' by 'l' and by V to get the answer, l = A/w.

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

y = -2x + 4

2x + y = 4

Step 2: Solve for x

Substitution

Substitute in y: 2x + (-2x + 4) = 4
Combine like terms: 4 = 4

Here we see that 4 does indeed equal 4.

∴ the systems of equations has an infinite amount of solutions.

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.
