Jenna grabs a sample of trail mix from a bag. The mix contains peanuts, almonds, raisins, cashews, and chocolate chips. She wants to guess how many chocolate chips are in the bag (they're her favorite). Help Jenna choose which sample size will give the best indication of how many chocolate chips are in the bag. Arrange the sample sizes starting with the sample that will give the most accurate prediction and ending with the sample that will give the least accurate prediction. a sample of 10 pieces a sample of 5 pieces a sample of 40 pieces

10 5 40

Step-by-step explanation:

if it is a sample and there are 5 diffrant things that is supposed to be in there,  the 5 would be just rediculus, if it is 10, that would make more sense. 40, that would be more like the regular versian of it

hope this helps!!!

step-by-step explanation:

equation

you are asked to write the equation

  expression = 0

using the given expression. when you do that, you have

  2x^2-2x-12 = 0

factoring

you can see that each of the coefficients is even, so a factor of 2 can be removed immediately.

  2(x^2 -x -6) = 0

if you multiply the binomials (x+a)(x+b), you get

  (x +a)(x +b) = x^2 +(a+b)x +ab

this tells you the coefficient of x is the sum of two factors of the constant term. here, that means -1 is the sum of two factors of -6. we want to know those factors so we can factor the trinomial.

  -6 = -1×6 = -2×3 = -3×2 = -6×1

the factor pair that sums to -1 is {-3, 2}, so our factorization is

  2(x -3)(x +2) = 0

solutions

the solutions to this equation are the values of x that make the product zero. a product is zero only when only of the factors of the product is zero. here, that means

  x - 3 = 0

  x = 3 . . . add 3 to both sides of the equation

or

  x +2 = 0

  x = -2 . . . add -2 to both sides of the equation

the solutions to the equation are x=3 or x=-2. both of these values of x satisfy the equation—they make it be true.

answer: for each 3 girls there is 2 boys . 3: 2
