There are 13 clubs in a standard 52 card deck. The first time you draw a club the odds of doing it are
13/52 = 1/4
The second time you draw a club, the number of clubs have gone down by 1 and the number of cards in the deck have also gone down by 1.
So this time the odds are12/51
The probability of both happening, one after the other without replacement is
1/4 * 12/51 = (1*12)/(4*51) = 12/204 = 3/51 = 1/17
1/17 = 0.0588
Answer:
The rule is: y = -10x+85
Step-by-step explanation:
The rule is given by:

Here m is the gradient and b is the y-intercept.
We have to take two pairs of input-output to find the rule
Let the two pairs be:
(x1,y1) = (1,75)
(x2,y2) = (2,65)
Slope is found using the formula:

Putting the values

Putting the value of slope

Putting a pair of input-output in the equation (1,75)

Putting the value of b

Hence,
The rule is: y = -10x+85
I believe that is cubed. sense cubic unit is 3 and that has 3 numbers after the decimal point.

Step-by-step explanation:

13^2 + 2 * 13 * n + n^2 = 18^2
169 + 26n + n^2 = 324
26n + n^2 = 324 - 169
26n + n^2 = 155
n^2 + 26n - 155 = 0
(n - 5)(n + 31) = 0
n - 5 = 0
n = 5
n + 31 = 0
n = -31.....not this one because it is negative
so n = 5 <===
