Answer:

Option C.

Step-by-step explanation:

The original value of  Investment = $3,000

It has a 10% chance of ending up with a value of $2,000.

Chances of loss of $1000 = 0.1

It has a 80% chance of ending up with a value of $3,500.

Chances of profit of $500 = 0.8

It has a 10% chance of ending up with a value of $4,000.

Chances of profit of $1000 = 0.1

Expected change in the value of investment is

Change=(-\$1000)(0.1)+(\$500)(0.8)+(\$1000)(0.1)

Change=-\$100+\$400+\$100

Change=\$400

The expected change in the value of the investment is $400.

The expected value of an original Investment of $3,000 is

\$3000+\$400=\$3400

Therefore, the correct option is C.

The pyramid below has a square base.
zavuch27 [327]

The volume of the pyramid would be 2406.16 cubic cm.

<h3>How to find the volume of a square-based right pyramid?</h3>

Supposing that:

The length of the sides of the square base of the pyramid has = b units

The height of the considered square-based pyramid = h units,

The pyramid below has a square base.

h = 24.4 cm

b = 17.2 cm

Then, its volume is given by:

V = \dfrac{1}{3} \times b^2 \times h \: \rm unit^3

V = \dfrac{1}{3} \times 17.2^2 \times 24.4 \: \rm unit^3\\\\V = 2406.16

Therefore, the volume of the pyramid would be 2406.16 cubic cm.

Can someone help me with this and explain please
Artyom0805 [142]
X/y = 2 so x = 2y
z/x = 4 so z = 4x but x = 2y so z = 4(2y) = 8y

now you have
x = 2y, z = 8y 

x + y + z          2y  + y + 8y             11y              11
------------ = -----------------------= ------------- =   ----------- = 5 1/2
     x                          2y                  2y                  2
