Winning the jackpot in a particular lottery requires that you select the correct five numbers between 1 and 34 and, in a separa

Marina CMI [18]

<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 $\frac{1}{10,295,472}$

PLEASE HELP! [99 POINTS] !! SERIOUS ANSWERS ONLY !!!

umka21 [38]

Hello!

We can find out our answer by plugging in the point (1,1) to see which equation works.

y=1.4(1.2)≠1
y=1.2≠1
y=0.5+0.3≠1
y=0.2+1.2≠1

As you can see, none of these answers are correct. You could make the last equation true by switching 0.2 to -0.2. It may have been a typo, so I would say the best answer is D.

I hope this helps!

Answer:

x = -2

Step-by-step explanation:

Equation is given as;

4 x - 5 = 2 + 3 ( x - 3 )

Step 1: Expand the brackets

4x - 5 = 2 + 3x - 9

Step 2: Collect like terms

4x - 3x = 2 - 9 - (-5)

Step 3: Simplify

x = 2 - 9 + 5

x = -2
