Find the volume of a pyramid with a square base, where the area of the base is 7.9 m^2

Fofino [41]

The pyramid formula:
$\frac{1}{3} \times base \times height$

The volume in this case would be:

1/3×7.9×4
=79/30×4
=10.5333...
≈10.5 m^3

Steps to sloving -2(x+3)=-10

FromTheMoon [43]

Answer:

Step-by-step explanation:

$-2(x+3)=-10$ <em>divide both sides by (-2)</em>

$\dfrac{-2(x+3)}{-2}=\dfrac{-10}{-2}$

$x+3=5$ <em>subtract 3 from both sides</em>

$x+3-3=5-3$

$x=2$

The time (in minutes) required to learn the procedure for performing a certain task is uniformly distributed on the interval fro

PtichkaEL [24]

Answer:

$P( X > 46) = 0.7 \ minute$

$\mu = 42 \ minute$

Step-by-step explanation:

From the question we are told that

The procedure for performing a certain task is uniformly distributed on the interval from( a = 32 )minutes to (b= 52) minutes

Generally the cumulative distribution function for continuous uniform distribution is

$F(x) = \left \{ {{0 \ \ \ \ \ for \ x \ x < a} \atop {\frac{x-a}{b-a} } \ \ for \ a \le x \ge b} \atop {1 \ \ \ \ \ \ \ for \ x > b }\right.$

Generally the probability that it takes more than 46 minutes to learn the procedure is mathematically represented as

$P( X > 46) = F(46) = \frac{46 - 32}{52-32}$

=> $P( X > 46) = 0.7 \ minute$

Generally the average time required to learn the procedure is mathematically represented as

$\mu = \frac{a + b}{2}$

=> $\mu = \frac{32 + 52}{2}$

=> $\mu = 42 \ minute$
