21. The odd numbers on a regular die are painted red. On a second regular die, the numbers that are one less than a perfect squa
ivanzaharov [21]

The chance that both come up red is 2/3.

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

First regular die :

The total outcomes are {1,2,3,4,5,6} = 6

Painted red are odd numbers {1,3,5} = 3

Second regular die :

The total outcomes are {1,2,3,4,5,6} = 6

Painted red are one less than perfect square which is 4-1 is {3} = 1

  • Probability (both red) = (red in 1st die / total outcome) + (red in 2nd die / total outcome)

P(both red) = 3/6 + 1/6

⇒ 4/6

⇒ 2/3

Determine all numbers at which the function is continuous. <br> Picture provided below
Ne4ueva [31]

Answer:

Choice D

Step-by-step explanation:

The function will be continuous everywhere except where the function in the denominator is 0. We, therefore determine the value(s) of x for which the function will be 0;

x^{2} -6x+8=0\\x^{2} -2x-4x+8=0\\x(x-2)-4(x-2)=0\\(x-4)(x-2)=0\\x=4\\x=2

Therefore, the points x= 2 and x =4 are points of discontinuity

The excluded values of a rational expression are –3, 0, and 8. Which of the following could be this expression?
e-lub [12.9K]
Excluded values are -3, 0 and 8, so denominator will be:

(x-(-3))\cdot(x-0)\cdot(x-8)=(x+3)\cdot x\cdot(x-8)=(x+3)(x-8)x=\\\\=(x^2-8x+3x-24)x=(x^2-5x-24)x=\boxed{x^3-5x^2-24x}

Answer A.
