A cosmetics company conducted a survey to anticipate potential sales of various new products from its upcoming catalog. The survey was conducted by randomly selecting women from two different age groups with 400 women in each group. The women selected the product that they would most likely purchase when it became available. The results obtained are given in the table shown below.
Products Ages 21 - 30 Ages 31 - 40
Product 1 163 152
Product 2 84 89
Product 3 104 109
Product 4 49 50
Which of the following statements about the data above is true?
A.
The estimates for both age groups show an equal number of women would have voted for Product 3.
Well the first obvious thing is that the axis of symmetry is 0.5, so we can automatically cross out (C).
All the answers have the correct vertex, so lets find the formula for the function.
Fortunately, from my point of view, I can see two points that have their coordinates as integers, (-1, -3) and (2, 3), we can plug these into the already given "formulas" in the options (A), (B), and (D).
Out of the three choices, the formula in option (D) satisfies both coordinates, thus option (D) is correct.
Answer:
A) 390
Step-by-step explanation:
Answer:
C: x = 1/2
Step-by-step explanation:
Set the divisor, 2x - 1, equal to zero and solve for x: 2x = 1, so x = 1/2. Statement C is true.
