As part of a new advertising campaign, a beverage company wants to increase the dimensions of their cans by a multiple of 1.12.
olga_2 [115]

Answer:

The new can can hold upto volume of 476.69 cubic centimeters.

Step-by-step explanation:

Diameter of the can = d = 6 cm

Radius of the can = r = 0.5d = 0.5 × 6 cm = 3 cm

Height of the can = h = 12 cm

Company wants to increase the dimensions of their cans by a multiple of 1.12. So, the new dimension will be:

r'= 3 cm × 1.12 = 3.36 cm

h' = 12 cm × 1.12 =13.44 cm

Volume of the = can = V

Volume of a cylinder = \pi r^2h

V=\pi r'^2h'

=3.14\times (3.36 cm)^2\times 13.44 cm=476.6808 cm^3\approx 476.68 cm^3

The new can can hold upto volume of 476.69 cubic centimeters.

Approximately 9 out of every 50 people who saw a movie this week say they watched it on Netflix. Suppose we want to find the pro
uysha [10]

Answer:

<u></u>

  • <u>1. As a fraction: 9/50</u>
  • <u>2. As a proportion: x/1 = 9/50</u>
  • <u>3. As a percentage: 18%</u>

<u></u>

Explanation:

<u>1. As a fraction:</u>

Depart from the definition of probability: probability is the number of favoragle outcomes divided by the total number of possible outcomes:

  • Probability = number of movie-goers who say they watched a movie on Netflix this week / number of movie-goers that saw a movie this week

  • Probability = 9 / 50

<u>2. As a proportion:</u>

A proportion is the equality of two ratios. In this case you must set the ratio of people who say they watched it on Netflx, x, per every people who saw a movie this week, 1, equal to the ration 9 /50.

Hence, the proportion that shows the probability is:

  • x / 1 = 9 / 50

Where x is the probability.

<u>3. As a percentage</u>

You just have to multiply the probability by 100:

  • (9/50) × 100 = 18%
