The value of 7 in 67098 is 7000 and the value of 7 in 74702 is 70000 or 700 so it is either 10 times or 1/10th of the the value.
Answer:


Step-by-step explanation:
<u>Given function</u>:

If (x + 2) is a factor then:

Expand:



To find <em>a</em>, compare the coefficients of x³:

To find <em>b</em>, substitute the found value of <em>a</em> into the coefficient for x² and compare:



To find <em>c</em>, compare the constants:


Therefore:

Now factor (3x²-8x+5):



Therefore the factored function is:

<u>Zero Product Property</u>

To find the zeros, set each factor equal to zero and solve for x:



Therefore, the zeros of the function are:

White block(s) = 2
Red block(s) = 1
Purple block(s) = 3
Total = 2 +1 + 3 = 6 blocks
a) P(white) =

P(red) =

P(purple) =

b)Not white block:
1 -

OR

Because, when they say no white blocks, we simply do not count them and add the rest to find that probability without white blocks.
c) The probability stays the same: lets say now we have
4 white blocks, 2 red, and 6 purple, total will be 12
P(white)=

which is still

d) We get two more blocks in the numerator: lets say we have 4 white blocks, 3 red, 5 purple (after adding 2 of each color), total will be 12
P(purple)=

(im not quite sure if my explanation here helps you though)
e) 1 more of white and purple, 5 more of red
white = 3, purple = 4, red = 6, total = 12
(you can either add 2 to white or purple but make sure you add 5 of red)
P(red)=
