When two six-sided dice are rolled, there are 3636 possible outcomes.

1 answer:

4 0

Total number of possible outcomes = 36

Total number of outcomes with sum not 4 = 33
not [1 + 3, 2 + 2, 3 + 1]

P(not sum of 4) = 33/36 = 11/12

Answer: 11/12

Factorise polynomial<br> 27y3 + 125z3<br><br>

tresset_1 [31]

Answer:

$27y^{3} +125z^{3} =(3y)^{3} +(5z)^{3}$

Apply the formula for sum of cubes: $a^{3}+b^{3}=(a+b)(a^{2}-ab+b^{2})$

Therefore:

$\left(3y\right)^3+\left(5z\right)^3=\left(3y+5z\right)\left(3^2y^2-3\cdot \:5yz+5^2z^2\right)$

$=\left(3y+5z\right)\left(9y^2-15yz+25z^2\right)$

Nick estimates 1/10+6/10 is about 1. Is his estimate reasonable? If not, estimate the sum

Margaret [11]

Answer:

His estimate is reasonable

Step-by-step explanation:

1/10 + 6/10 = 7/10, which can be rounded to 1

1/10, 2/10, 3/10, 4/10, 5/10, 6/10, 7/10, 8/10, 9/10, 1

As you can see, 7/10 is very close to 1.

Hope this helps!
