6p + 4 / 7 + 5p - 6 / 2 - 3p / 4 when p = 4
vesna_86 [32]

Step-by-step explanation:

Given p = 4,

substitute p= 4 into the expression

6p+4/7+5p-6/2-3p/4

6(4) +  \frac{4}{7}  + 5(4) -  \frac{6}{2}  -  \frac{3(4)}{4}  \\  = 24 +  \frac{4}{7}  + 20 - 3 - 3 \\  = 44 +  \frac{4}{7}  - 3 - 3 \\  = 38 +  \frac{4}{7}  \\  = 38 \frac{4}{7}

Americans spend an average of 4 hours per day online.If the standard deviation is 26 minutes, find the range in whitch at least
Mamont248 [21]

Answer:

The range in which at least 88.89% of the data will lie is (162,318).

Step-by-step explanation:

Given:

Average time spend online, \bar x = 4 hrs = 240 mins

Standard deviation, s = 26 mins

We have to find the range in which at least 88.89% of the data will lie by using Chebyshev's theorem :

Formula :

Lower range = \bar x-ks

Higher range = \bar x +ks

Now we have to find k values.

We know that the percentage of the data that lies within 'k' standard deviation is at least,1-1/k^2 and k > 1.

⇒ 88.89\% = 0.8889

⇒ 1-\frac{1}{k^2} = 0.8889

⇒ 1-0.8889=\frac{1}{k^2}

⇒ 0.1111=\frac{1}{k^2}

⇒ \frac{1}{0.1111} =k^2

⇒ \sqrt{\frac{1}{0.1111} } =k

⇒ 3=k

Plugging the value of k=3 in the formula above.

The range is \bar x-ks,\bar x+ks .

⇒ 240-3(26), 240+3(26)

⇒ 240-78,240+78

⇒ 162,318

So,

The range in which at least 88.89% of the data will lie is (162,318).
