to figure out this equation, all you need to do is combine like terms!

x = 1x

4x = 4x

6x = 6x

1x + 4x + 6x = 11x

Hope this helped! :D

The mean height of an adult giraffe is 17 feet. Suppose that the distribution is normally distributed with standard deviation 0.

BARSIC [14]

Answer:

Median =17

Step-by-step explanation:

Given that the mean height of an adult giraffe is 17 feet. Suppose that the distribution is normally distributed with standard deviation 0.9 feet.

Let X be the height of a randomly selected adult giraffe.

X is a random variable.

a) X is N(17, 0.9)

b) Median giraffe height = 17 ft since in normal distribution mean = median

c) When x = 18.5, Z = $\frac{18.5-17}{0.9} =0.1667$

d) $P(X$

e) $P(16.9$

f) 75th percentile for z is 0.675

$x=17.9+0.9(0.675)\\= 18.5075$

How would the expression x^3+64 be written using sum of cubes

Hunter-Best [27]

$\bf \textit{difference and sum of cubes}
\\\\
a^3+b^3 = (a+b)(a^2-ab+b^2)
\\\\
a^3-b^3 = (a-b)(a^2+ab+b^2)\\\\
-------------------------------\\\\
\boxed{64=4^3}\qquad \qquad x^3+64\implies x^3+4^3\implies (x+4)(x^2-4x+16)$

A theater company charges $5.50 per ticket for people of all age groups. If c represents the total number of children who bought

harina [27]

The theater charges $5.5 per ticket per person of any age group.
Your expression would not have $5.5c or $5.5a as they have a price for only one variable.
Your expression would be 5.5(a+c).
Your first option is the correct one.
