Find the surface area of the figure below.
PSYCHO15rus [73]
The pyramid given above has four faces. Each of which are in triangular shape. The area of the triangle is calculated through the equation,

                       A = bh / 2
where A is area, b is base and h is the height. 

Substituting the known values,

                      A = (4 inch)(9 inch) / 2 = 18 in²

Multiplying this area by 4 will give us an answer of 72 in².


Then, we also calculate for the area of the square base.
                      A = s²
where s is the measure of each side of the square.

                       A = (4 in)² = 16 in²

Finally, we add up the calculated areas.
                  surface area = 72 in² + 16 in²
                      <em>surface area = 88 in²</em>

Hence, the surface area of the figure is equal to 88 in².

Help! The options are: proportional , not proportional
storchak [24]

Answer:  Not proportional

=======================================================

Explanation:

Let's assume the two fractions are equal.

If so, then,

\frac{0.2}{2.6} = \frac{0.3}{3.6}\\\\0.2*3.6 = 2.6*0.3\\\\0.72 = 0.78

The last equation is false, so the first equation is false.

Therefore, the two ratios are <u>not</u> proportional.

-------------

Another approach:

Calculate the decimal value of each fraction

\frac{0.2}{2.6} \approx 0.07692\\\\\frac{0.3}{3.6} \approx 0.08333\\\\

The two ratios result in different decimal values, so the two ratios are not equal, aka not proportional.

A bag contains 1 red, 3 green, and 5 yellow balls. A sample of four balls is picked. Let G be the number of green balls in the s
Citrus2011 [14]

Answer:

P(Y=r) = 4Cr (5/9)^r (4/9)^{4-r},r=0,1,2,3,4

Step-by-step explanation:

Given that a bag contains 1 red, 3 green, and 5 yellow balls. A sample of four balls is picked, with replacement

When balls are picked with replacement, each time the ball picked up does not depend on the previous outcomes.

Thus given y=2 will not affect the pdf of G

In G, Y no of yellow balls can take values as 0,1,2,3,4

Prob of drawing a yellow ball each time = 5/9

Y = no of yellow balls is binomial with n =4 and p = 5/9

P(Y=0) = (1-5/9)^4 = (\frac{4}{9} )^4

In general,

P(Y=r) = 4Cr (5/9)^r (4/9)^{4-r},r=0,1,2,3,4
