In the Minnesota Northstar Cash Drawing, you pick five different numbers between 1 and 35. What is the probability of picking th

maw [93]

Answer:

$\frac{1}{324632}$ probability of picking the winning combination

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Since the order is not important, the combinations formula is used to solve this question.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

Desired outcomes:

The correct five numbers from a set of 5. So

$D = C_{5,5} = \frac{5!}{5!0!} = 1$

Total outcomes:

Five numbers from a set of 35. So

$T = C_{35,5} = \frac{35!}{5!30!} = 324632$

Probability:

$p = \frac{D}{T} = \frac{1}{324632}$

$\frac{1}{324632}$ probability of picking the winning combination

Jane has a bag of candy, she gives 8 to her friend. Then jane's grandmother buys 5 more pieces than jane had originally. Now jan

goblinko [34]

Answer:

12 Pieces

Step-by-step explanation:

Number of candies in Jane's bag = x

she gives 8 to her friend;

x - 8

Then jane's grandmother buys 5 more pieces than jane had originally; add (x + 5)

x - 8 + x + 5

Now jane has 27 pieces of candy

x - 8 + x + 5 = 27

Solve for x;

x - 8 + x + 5 = 27

2x - 3 = 27

2x = 27 -3

2x = 24

x = 12

The variable z is directly proportional to x, and inversely proportional to y. When x is 9 and y is 6, z has the value 19.5. Wha

Pavel [41]

Given that, the variable z is directly proportional to x, and inversely proportional to y.

So, we can set up an equation as following:

$z= k \frac{x}{y}$ Where k = constant of variation.

Another information given in the problem is, when x is 9 and y is 6, z has the value 19.5.

So, x = 9, y = 6 and z = 19.5.

Let's plug in these values in the above equation. So,

$19.5= k \frac{9}{6}$

19.5 = k* 1.5

$\frac{19.5}{1.5} =k$ Divided each sides by 1.5 to isolate k.

So, k = 13.

Hence, the equation will be $z= 13 \frac{x}{y}$ .

Now we need to find the value of z when x= 14, and y= 11 . Therefore,

$z= 13*\frac{14}{11}$

$z= \frac{182}{11}$

So, z= 16.5 (Rounded to tenth).

Hope this helps you!
