Two number cubes are rolled. What is the probability that the sum of the numbers rolled is either 3 or 9?

1 answer:

7 0

$|\Omega|=6^2=36\\ |A|=\underbrace{2}_{\text{the sum is 3}}+\underbrace{4}_{\text{the sum is 9}}=6\\\\ P(A)=\dfrac{6}{36}=\dfrac{1}{6}\approx17\%$

Answer:

-20x³ + 0x² + 15x - 20

Step-by-step explanation:

I would have said it the other way.

"Multiply each term in the top row by -5."

4x³ + 0x - 3x + 4

×(-5) ×(-5) ×(-5) ×(-5)

-20x³ + 0x² + 15x -20

Write your answer without using negative exponents. (w^5)^-7

Blababa [14]

Answer:

1/(w^35)

Step-by-step explanation:

According to the rules of exponents, you need to multiply both -7 and 5 such that you get...

w^(-35)

Since you cannot have a negative exponent according to the question, you simplify by...

w^-x means that you do 1/(w^-x)

1/(w^35)

Which equation represents a parabola that opens upward, has a minimum at x = 3, and has a line of symmetry at x = 3?

Licemer1 [7]

Answer:

A. y = x^2 -6x + 13

Step-by-step explanation:

The parabola that opens up and has line of symmetry x=3 and a minimum at x=3 is

$y=x^2-6x+13$

The reason is that, we can write this function in the vertex form to get;

$y=x^2-6x+(-3)^2+13-(-3)^2$

$y=(x-3)^2+13-9$

$y=(x-3)^2+4$

Hence the line of symmetry is x=3 and the vertex is (3,4)
