The volume of a square prism is 144x^3 +216x^2 +81x

Svetach [21]

Answer:

Equation for the perimeter of prism's square face: 16x + 12

Step-by-step explanation:

Volume of Square prism = Length * Width * Height

= 144 x^3 + 216 x^2 +81 x

taking 9x common = 9x( 16 x^2 + 24 x + 9)

= 9x ( (4x)^2 + 2(4x)(3) + (3)^2 )

= 9x ( 4x+3)^2

so the length is 9x, width is 4x+3 and height is 4x+3

Now, Perimeter of prism's square face = 2* Width + 2 * Height

= 2* (4x+3) + 2* (4x+3)

= 8x +6 + 8x + 6

= 16x +12

(a) Suppose one house from the city will be selected at random. Use the histogram to estimate the probability that the selected

Mila [183]

Answer:

a) 0.71

b) 0.9863

Step-by-step explanation:

a. Given the mean prices of a house is $403,000 and the standard deviation is $278,000

-The probability the probability that the selected house is valued at less than $500,000 is obtained by summing the frequencies of prices below $500,000:

$P(X$

Hence, the probability of a house price below $500,000 is 0.71

b. -Let X be the mean price of a randomly selected house.

-Since the sample size 40 is greater than 30, we assume normal distribution.

-The probability can therefore be calculated as follows:

$P(X$

Thus, the probability that the mean value of the 40 houses is less than $500,000 is 0.9863

What is the rational number equivalent to 3 point 12 with a bar over 12?

slamgirl [31]

$\frac{12}{100}=0.12$

To get the 0.12 to repeat, the trick is to subtract 1 from the denominator

$\frac{12}{99}=0.12121212...$

Then reduce the fraction.

$\frac{12}{99}={4}{33}$

now add the 3 to get

$3.12121212.... = 3\frac{4}{33}$
