A bakery asks 75 customers to vote for a new bagel flavor. Onion flavor receives 33 votes. Cheddar flavor receives 42 votes. Use
m_a_m_a [10]

Using proportions, it is found that:

  • The fraction that shows the proportion of customers who voted for cheddar flavor is \frac{42}{75}
  • 56% of customers voted for cheddar flavor.

  • A proportion is the <u>number of desired outcomes divided by the number of total outcomes</u>.
  • A percentage is the <u>proportion multiplied by 100%</u>.

In this question, 42 out of 75 customers voted for the cheddar flavor, hence:

p = \frac{42}{75}

That is, the fraction that shows the proportion of customers who voted for cheddar flavor is \frac{42}{75}

The percentage is:

\frac{42}{75} \times 100\% = 56\%

56% of customers voted for cheddar flavor.

Answer:

A) A dilation by a scale factor of 2, centered at the origin, followed by a 180° clockwise rotation about the origin.

Step-by-step explanation:

a dilation by a scale factor of 2, centered at the origin will double its size and move point A from (-2,2) to (-4,4). Then the clockwise rotation of 180° degrees will rotate the figure so that it's point A (now called point D) will be at (4,-4).
