ozzi

Substitute the numbers in the equation:

$V=LWH$

Since L=5in, W=4in and H=8in:

$\begin{gathered} V=(5in)(4in)(8in) \\ =160in^3 \end{gathered}$

Therefore, the volume is equal to 160 inches cubed.

Answer:

$Probability = \frac{1}{24}$

Step-by-step explanation:

Given

$Oranges = 3$

$Apples = 5$

$Banana = 2$

$Total = 10$

Required

Determine the probability of 1 orange, 1 apple and 1 banana

Since, order is not important:

$Probability = P(Orange) * P(Apple) * P(Banana)$

$Probability = \frac{3}{10} * \frac{5}{9} * \frac{2}{8}$

<em>The difference in the numerator is as a result of picking the fruit without replacement</em>

$Probability = \frac{30}{720}$

$Probability = \frac{1}{24}$

What is x?? I'm so confused!

LiRa [457]

Answer:

x = 468%

Step-by-step explanation:

I see a proportion here.

we want to solve for the variable x in the proportion:

18% / (2 weeks) = ( x %) / (52 weeks)

here we should multiply 52 to boths sides

(52 weeks) * 18% / (2 weeks) = x %

26 * 18% = x %

x = 468 %
