The best information we can use is the ratio of defectuosity, 2/150
Applying it to the size of the batch
N=3000*2/150 = 40
Answer: out of the batch of 3000 products, likely 40 products are defective, if the products are drawn from the same production run.

Letter B is the answer

Number of sides (n) = 8
Apothem (a) = 18.11 units
Side (s) = 15 units

Area of Octagon = (1/2)n*a*s
A of O= (1/2)*8*18.11*15
A of O= 1086.6 units^2


Area of Square = s^2
A of S = 15^2
A of S = 225 units^2


Area of Shaded Region = A of O - A of S
A of S.R. = 1086.6 units^2 - 225 units^2
A of S.R. = 861.6 units^2
A of S.R. = 862 units^2

What is the greatest common factor of 117 & 351
Ivan
So we factor out the number and find the number in both numbers so
117=3*3*13
351=3*3*13*3
so the greatest common factor of 117 and 351 is 3*3*13=117

35=7*5
149=prime=149 (prime means no whole factors)

Sara has 20 sweets.
nalin [4]

Answer:

The probability that the two sweet will not be same type is \frac{111}{190}

Step-by-step explanation:

P(two sweets not same) = 1 - P( two sweets will be same)

There are 3 possible outcomes where two sweets will be same.

1. it can be two liquor-ice, 2. it can be 2 mint and 3. it can be two humbug

P(two liquor-ice) =\frac{12}{20} \times\frac{11}{19}= \frac{33}{95}

P(two mint) =\frac{5}{20} \times \frac{4}{19} =\frac{1}{19}

P(tow humbug) =\frac{3}{20} \times\frac{2}{19} =\frac{3}{190}

Now we have:

P(two sweets not same) = 1 - P( two sweets will be same)

                                  =1- \left(\frac{33}{95}+ \frac{1}{19}+ \frac{3}{190} \right)

                                   1-\frac{79}{190}

                                   =\frac{111}{190}

Therefore, the probability that the two sweet will not be same type is \frac{111}{190}
