two dice are rolled in succession. determine the probability that their sum is 10 or more,given that the first die is a 5
MrRa [10]
If the first die is a 5, the second must be 5 or more in order to have a sum of at least ten.

Assuming it is a six sided die, the two values that would make this true are 5 and 6.

2 values/6 possible would be a probability of 2/6, which simplifies to 1/3

Final answer: 1/3

algol [13]

Answer:

  • a = ± 2

Step-by-step explanation:

Let the scale factor is k.

<u>Then the transformation is:</u>

  • (x, y) → (kx, ky)

<u>We have:</u>

  • (x, y) → (12x, 3a²y)

<u>The scale factor is k = 12, find the value of a:</u>

  • 3a² = 12
  • a² = 4
  • a = √4
  • a = ± 2

Is this equation a direct variation? Y= 4x + 9
Ket [755]
No it wouldn't because a direct variation is in a  y=kx formula. That equation shown above is in a y=mx+b format,which is a formula for slope intercept form

Solve the equation (x-2)^2/3=9
statuscvo [17]

Answer:

x = 2±3sqrt(3)

Step-by-step explanation:

(x-2)^2/3=9

Multiply each side by 3

(x-2)^2/3 *3=9*3

(x-2)^2=27

Take the square root of each side

sqrt( (x-2)^2)=±sqrt(27)

x-2 = ±3sqrt(3)

Add 2 to each side

x = 2±3sqrt(3)
