The American Community Survey is completed by the US Census Bureau to obtain information about households in the US. One variabl

e of interest is how many people reside in each household (vacant households were recorded as having zero people). Based on data from 2014, here is the partially completed probability distribution of H, the number of people residing in a randomly selected US household:
H 0 1 2 3 4 5+
P(H) ? 0.24 0.30 0.14 0.11 0.09

Answer:

The missing probability is 0.12        

Step-by-step explanation:

We are given the following in the question:

  H:  0      1         2         3       4       5

P(H): x   0.24   0.30   0.14   0.11   0.09

Let x be the missing probability.

Property of discrete probability distribution:

\displaystyle\sum P(x_i) = 1\\\Rightarrow  x+ 0.24+ 0.30+ 0.14 +0.11 +0.09 = 1\\\Rightarrow x + 0.88 = 1\\\Rightarrow x  = 1 - 0.88\\\Rightarrow x = 0.12

Thus, the missing probability is 0.12

Need help in math and explain to me step by step
Rus_ich [418]

Answer:

\left[\begin{array}{cc}x&y&-2&-9&0&-1&2&7&4&15\end{array}\right]

Step-by-step explanation:

Given

y = 4x - 1

Required

Create a function table for inputs -2, 0, 2 and 4

When x = -2

y = 4*-2 - 1 = -9

When x = 0

y = 4*0 - 1 = -1

When x = 2

y = 4*2 - 1 = 7

When x = 4

y = 4*4 - 1 = 15

So, the table is:

\left[\begin{array}{cc}x&y&-2&-9&0&-1&2&7&4&15\end{array}\right]

Need help with number 6 and how did you get it
Soloha48 [4]
A rectangular prism is just a shape that looks like a brick.

If you think about a brick for a few seconds, you'll realize
that it has

-- 2 faces of  (length by width)
-- 2 faces of  (length by height)
and
-- 2 faces of  (width by height).

The dimensions of the brick in question 6 are 8ft, 3ft, and 5ft.
So it has

-- 2 faces of  8ft  by  3ft
-- 2 faces of  8ft  by  5ft
and
-- 2 faces of  3ft  by  5ft .

Can you take over and complete it now ?
