Let me explain this to you....

7 1/7...to turn this into an improper fraction, take ur whole number (7) and multiply it by ur denominator (7 x 7 = 49), then add ur numerator (1)....49 + 1 = 50....now put that over ur original denominator (7)....resulting in :
50/7. <== ur answer

In summary : (whole number x denominator + numerator) / original denominator.

"A shipment has 20 items. Five items will be picked randomly and checked for quality. If at least one item is defective, then th
Thepotemich [5.8K]

Answer:

1 - \frac{(20-k)(19-k)(18-k)(17-k)(16-k)}{20*19*18*17*16}

Step-by-step explanation:

If k items out of 20 total items are defective, then the number of non-defective item is 20 – k. The probability of choosing 5 items where all of them are non-defective is

- For the 1st slot the chance is (20 – k)/20

- For the 2nd slot the chance is (20-k-1)/(20-1) = (19-k)/19

- For the 3rd slot: (18 – k)/18

- 4th : (17 – k)/17

- 5th: (16 – k)/16

The probability in total would be

\frac{(20-k)(19-k)(18-k)(17-k)(16-k)}{20*19*18*17*16}

So the probability of selecting at least 1 defective item is the inverse of this, which is

1 - \frac{(20- k)(19-k)(18-k)(17-k)(16-k)}{20*19*18*17*16}

jeyben [28]

WHEN GRAPHING

Step 1. Convert to y = mx + b

  • Equation 1: y = 3x/2 - 16/2
  • Equation 2: y = -5 - 2x

Step 2. Graph like normal

  • Find zeros & plot
  • Find y-intercept & plot

Step 3. Shade as indicated by the inequality symbol

  • > or ≥ = above line
  • < or ≤ = below line

Step 4. If  ≤ or ≥ ONLY, then also shade the line

FOR THIS PROBLEM

1. Graph each equation

2. Shade ABOVE line for each

3. Shade line first equation as well

Hope this helps and God bless!

Writing a geometry proof seems to take a very specific kind of skill along with a specialized vocabulary. Yet you have also seen
ANTONII [103]

In geometry proofs, we commonly use step-by-step logic to figure out the proof. This is commonly used in Computer Science for understanding how computers work, process, and store information(I speak from personal experience). This is also commonly used in Law. You use this in Law as a lawyer to deduce information using step-by-step logical processes and logic, otherwise it's just wishful thinking. So, Law also uses the same reasoning skills used in Geometry proofs.
