- \dfrac{4}{3} x - 6 = -26

//Add 6 to both sides:
- \dfrac{4}{3} x  = -20

//Multiply by -1 on both sides:
\dfrac{4}{3} x  = 20

Multiply by 3 on both sides:
4x  = 60

Divide by 4 on both sides:
x  = 15

Answer: x = 15 (Answer C)

The answer would be C. I found this out by adding 6 to the -6 and the -26. Then you divide -4/3 by -20 which is 15. Hope this helps! :)

Write the equation for a parabola with the focus at
katen-ka-za [31]
The answer is (y - 4)2 = -12(x - 2)
Since the graph is facing the left, the starting equation would be (y - k)2 = -4p(x - h).
(h, k) is the vertex of the graph. If you plot the focus and the directrix, you can see that the distance is 6. Divide 6 by 2, thus the vertex should be 3 squares away from the focus and 3 squares away from the directrix. The vertex is (2, 4). And since the distance from the focus to the vertex and the distance from the directrix to the vertex is 3, P = 3.
Insert the numbers in and you should get the last choice.

Answer:

see below and attached

Step-by-step explanation:

To solve a system of quadratic equations:

  • Equal the equations then rearrange so that it is set to zero.
  • Use the quadratic formula to solve.

I have done this (see attached workings) but cannot get any of the solutions you've provided.  I have even graphed the two functions, and the points of intersection concur with my workings (see attached graph).

SashulF [63]

Answer: 0.0473

Step-by-step explanation:

Given : The proportion of gambling addicts : p=0.30

Let x be the binomial variable that represents the number of persons are gambling addicts.

with parameter p=0.30 , n= 10

Using Binomial formula ,

P(x)=^nC_xp^x(1-p)^{n-x}

The required probability = P(x>5)=P(6)+P(7)+P(8)+P(9)+P(10)\\\\=^{10}C_6(0.3)^6(0.7)^{4}+^{10}C_7(0.3)^7(0.7)^{3}+^{10}C_8(0.3)^8(0.7)^{2}+^{10}C_9(0.3)^9(0.7)^{1}+^{10}C_{10}(0.3)^{10}(0.7)^{0}\\\\=\dfrac{10!}{4!6!}(0.3)^6(0.7)^{4}+\dfrac{10!}{3!7!}(0.3)^7(0.7)^{3}+\dfrac{10!}{2!8!}(0.3)^8(0.7)^{2}+\dfrac{10!}{9!1!}(0.3)^9(0.7)^{1}+(1)(0.3)^{10}\\\\=0.0473489874\approx0.0473

Hence, the required probability = 0.0473
