I made a fort by two boxes. The first box is 4 meters long, 8 meters wide, and 8 meters high. The second box is 2 meters long, 7

ArbitrLikvidat [17]

Answer:

242 m³ of space is there in the fort.

Step-by-step explanation:

Given that,

The dimensions of first box is 4 meters long, 8 meters wide, and 8 meters high.

The dimensions of the second box is 2 meters long, 7 meters wide, and 1 meter high.

Space left = Volume of first box - volume of second box

= (4)(8)(8) - 2(7)(1)

= 242 m³

So, 242 m³ of space is there in the fort.

An adult can lose or gain two pounds of water in the course of a day. Assume that the changes in water weight are uniformly dist

Levart [38]

Answer:

Standard deviation of the weight over a day is 1.15

Step-by-step explanation:

Since it is given that water weight is uniformly distributed between -2 to 2.

So applying formula for variance of uniformly distribution as follows,

$variance=\dfrac{\left (b-a\right )^{2}}{12}$

From the given data, values of a and b is , $a=-2$ , $b=2$ ..

Substituting the values,

$variance=\dfrac{\left (2-\left (-2 \right )\right )^{2}}{12}$

Now, $-\left ( -2 \right )=2$

$variance=\dfrac{\left (2+2\right )^{2}}{12}$

$variance=\dfrac{\left (4\right )^{2}}{12}$

$variance=\dfrac{16}{12}$

Dividing the fraction by 4,

$variance=\dfrac{4}{3}$

So, the value of variance is $\dfrac{4}{3}$

The formula for standard deviation is given as,

$Standard\:deviation=\sqrt{variance}$

Substituting the value,

$Standard\:deviation=\sqrt{\dfrac{4}{3}}$

$Standard\:deviation=1.15470$

Rounding to 2 decimal places,

$Standard\:deviation=1.15$

So, the value of standard deviation is 1.15.
