Answer:

20,000 cm³
54 kg

Step-by-step explanation:

1 m is 100 cm, so the volume is ...

V = LWH

V = (100 cm)(50 cm)(4 cm) = 20,000 cm³ . . . volume

The mass is ...

(20,000 cm³)(2.7 g/cm³) = 54,000 g = 54 kg

The mass of the block is 54 kg.

i forgot how to find equivalent fractions. i know that the bottom would be times by 3 to get 18 but if you times 3 by 3 it would

tester [92]

Set up a proportion. take 3/6 = 20/x
Cross multiply 3 * x = 6 * 20
Simplify 3x = 120
Divide by 3 x = 40
So the denominator of the bottom fraction is 40

If x is uniformly distributed over the interval 8 to 12, inclusively (8 x 12), then the probability, p(13 x 15), is ____________

kap26 [50]

$f_X(x)=\begin{cases}\dfrac1{12-8}=\dfrac14&\text{for }8\le x\le12\\\\0&\text{elsewhere}\end{cases}$

This means $\mathbb P(13\le x\le15)=0$ since this interval lies outside the support of the density function.
