The formula is : A=6a^2

So lets say its a cube with edge lengths of 4

We first find out the area of each side by multiplying 4*4

They you multiple the answer of that, 16, by 6, for each of the sides.

A = 96 Units ^2

Use complete sentences to analyze the graph of the function f(x) = log 1/3 x.
oksian1 [2.3K]
Y = log (1/3) x
Part 1:
Domain :  x ∈ ( 0, + ∞ ).
Range:  y ∈ R.
General shape: The graph is decreasing.
Part 2 :
We will choose those points: x = { 1/3,  1,  3,  9 }
Ordered pairs ( for graphing the function ) are :
f ( x ) = { ( 1/3, 1 ), ( 1. 0 ), ( 3, - 1 ), ( 9, - 2 ) }. 
There is no y - intercept and x - intercept is 1.

360*2=720 720/40=18
360 is the measure, in degrees of a pizza becasue it is a circle. There are two pizzas, or two circles. Each wedge is 40°, meaning that you need to divide the pizzas by the size of a wedge.

The pmf of the amount of memory X (GB) in a purchased flash drive is given as the following. x 1 2 4 8 16 p(x) 0.05 0.10 0.30 0.
ArbitrLikvidat [17]

Answer:

E(x) = 7.05

Step-by-step explanation:

We are given the following information in the question:

  x:        1              2              4              8              16

p(x):     0.05        0.10          0.30         0.40         0.15

Formula:

E(x) = \sum x.p(x)\\= (1)(0.05) + (2)(0.10) + (4)(0.30) + (8)(0.40) + (16)(0.15)\\= 7.05

Hence, the expectation of the given data is 7.05
