Answer:

SA = 124 cm²

Step-by-step explanation:

The lateral surface area is the area of all sides besides that base, so 93 cm² is the sum of 3 sides of the tetrahedron.

93/3 = 31 cm² per side, there are 4 sides, so 31(4) = 123 cm² is the total surface area

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.

Fed [463]

Answer:

$T_{-6, 1} \circ r_{x-axis}$

Step-by-step explanation:

Reflection over x-axis transforms ABCD into A'B'C'D'. This is symbolized by $r_{x-axis}$

Translation 6 units to the left and 1 unit up, transforms A'B'C'D' into A''B''C''D''. This is symbolized by $T_{-6, 1}$

PLEASE HELP 25 POINTS <br> What is −4√12+√75 in simplest radical form? Enter your answer in the box.

Ber [7]

Answer: $-3\sqrt{3}$

This the expression -3*sqrt(3) or "-3 times the square root of 3"

=================================================

Work Shown:

Factor each term inside the square root so that a perfect square is one of the pieces. Then break up the roots and simplify as shown below.

$-4\sqrt{12} + \sqrt{75}$

$-4\sqrt{4*3} + \sqrt{25*3}$

$-4\sqrt{4}*\sqrt{3} + \sqrt{25}*\sqrt{3}$

$-4*2*\sqrt{3} + 5*\sqrt{3}$

$-8\sqrt{3} + 5\sqrt{3}$

$(-8+5)\sqrt{3}$

$-3\sqrt{3}$
