Answer:

range = (4, 20, 52 )

Step-by-step explanation:

Substitute the given values of x from the domain into the equation and evaluate for y ( the range )

x = 1 : y = 2(1)² + 2 = 2 + 2 = 4

x = 3 : y = 2(3)² + 2 = 18 + 2 = 20

x = 5 : y = 2(5)² + 2 = 50 + 2 = 52

range is y ∈ {4, 20, 52 }

<h3>The probability of winning the lottery is $\frac{1}{10,295,472}$ </h3>

Step-by-step explanation:

Here, the total numbers in the jackpot = 1 to 34

Now, the number that needed to be drawn = 5

The number of ways , 5 number can be drawn from total 34 numbers :

$^{34} C _5 = \frac{34!}{5!(34-5)!} = 278,256$

Also, in separate draw, the correct number drawn = 1

So, the number of ways that can be done = 30 C 5 x 37

= 278,256 x 37 = 10,295,472

Now, P(win) = $\frac{\textrm{Total favorable attempts}}{\textrm{Total attempts}} = \frac{1}{10,295,472}$

Hence, the probability of winning the lottery is $\frac{1}{10,295,472}$

Solve for A ? <br><br> Anyone willing to help me :)

GrogVix [38]

Answer:

Step-by-step explanation:

Use the cosine law:

$BC^2=AB^2+AC^2-2(AB)(AC)\cos(\angle A)$

We have:

$BC=a\\\\AB=4\\\\AC=3\\\\m\angle A=32^o\to\cos32^o\approx0.848$

Substitute:

$a^2=4^2+3^2-2(4)(3)(0.848)\\\\a^2=16+9-20.352\\\\a^2=4.648\to a=\sqrt{4.648}\\\\a\approx2.2$
