Daily low temperatures in Columbus, OH in January 2014 were approximately normally distributed with a mean of 15.45 and a standa
Alona [7]

Answer: 12.10

Step-by-step explanation:

Given : Mean : \mu = 15.45

Standard deviation : \sigma = 13.70

The formula to calculate the z-score :-

z=\dfrac{x-\mu}{\sigma}

For x= 5 degrees

z=\dfrac{5-15.45}{13.70}=-0.7627737226\approx-0.76

For x= 10 degrees

z=\dfrac{10-15.45}{13.70}=-0.397810218\approx-0.40

The P-value : P(-0.76

=0.3445783-0.2236273=0.120951\approx0.1210

In percent , 0.1210\times100=12.10\%

Hence, the percentage of days had a low temperature between 5 degrees and 10 degrees = 12.10%

Here is a cuboid,
Dmitry_Shevchenko [17]

<em>Length = </em><em>80</em>

<em>Breadth = </em><em>30</em><em>  </em>

<em>Height = </em><em>30</em>

<em>Total surface area of a cuboid is= </em>

<em><u>2 ( lb + bh + hl )</u></em>

<em>Putting the values in the formula,</em>

<em>We get,</em>

<em>= 2</em><em> [</em><em> (80 x 30) + (30 x 30) + (30 x 80)</em><em>]</em>

<em>= 2 (2400 + 900 + 2400)</em>

<em>= </em><em><u>8100 cm²</u></em>
