Answer:
There should be 18 blue marbles in the representative sample.
Step-by-step explanation:
Given that a bag contains 9 white and 54 blue marbles, if a representative sample contains 3 white marbles, to determine how many blue marbles would you expect to contain the following calculation must be performed:
9 = 3
54 = X
54 x 3/9 = X
162/9 = X
18 = X
Therefore, there should be 18 blue marbles in the representative sample.
Answer:
tan²A
Step-by-step explanation:
1+tan²A/1+cot²A Simplify 1+tan²A first
sec²A/1+cot²A Now simplify 1+cot²A
sec²A/csc²A Simplify sec²A and csc²A
/
Simplify the fraction
sin²A/cos²A = tan²A

<span>x : y is equal to 12 : 8. These can be reduced or cancelled down to 3 : 2 in the same proportions. Therefore, when y is 12, you have to multiply the smallest value y can be by 6, and must do the same to the smallest x value to retain the proportions. x = 18 when y = 12.</span>
Answer:
(x-3)(x-6)
Step-by-step explanation:
Fill in g into f and simplify:
(x-2)²-5(x-2)+4 =
x² - 4x + 4 - 5x + 10 + 4 =
x² - 9x + 18 =
(x-3)(x-6)
