Electronics Unlimited sells TVs. There are 110 TVs on display in the showroom, and each TV is turned on to a random channel from

Lynna [10]

Answer:

Option B. There will be close to 40 TVs but probably not exactly 40 TVs not showing a sports channel.

Explanation:

There are a total of 7 sports channels and 4 non-sports channels out of 11 channels.

The probability that one TV will be not be showing a sports channel, P(not S), is:

P(not S) = number of non-sports channels / number of channels.

P(not S) = 4/11.

The best prediction on how many TVs will not be showing a sports channel is, the expected value, which is equal to the number of TVs mulitplied by P(not S):

P(not S) = 110 × 4/11 = 40.

Since this is a random variable, the expected value is not the exact number of TV but just a probability.

Hence, the answer is the option B: There will be close to 40 TVs but probably not exactly 40 TVs not showing a sports channel.

$\sqrt[4]{(4a^{2})^{6}} = \sqrt[4]{4096a^{12}} = 8a^{3}$

$\sqrt[7]{(b^{\frac{5}{3}})^{8}} = \sqrt[7]{b^\frac{40}{3}} = b^{\frac{40}{21}} = \sqrt[21]{b^{40}} = \sqrt[21]{b^{21} * b^{19}} = \sqrt[21]{b^{21}} \sqrt[21]{b^{19}} = b\sqrt[21]{b^{19}}$

$\sqrt[3]{\frac{c^{9}}{c^{3}}} = \sqrt[3]{c^{6}} = c^{2}$

$\sqrt[3]{27d^{6} * 8d^{-4}} = \sqrt[3]{27d^{6} * \frac{8}{d^{4}}} = \sqrt[3]{216d^{2}} = 6\sqrt[3]{d^{2}} = 6d^{\frac{2}{3}}$
