Answer:
5√7 or 15.652
Step-by-step explanation:
is the numbers (-6,5) (8-2) or is it (-6.5) because of it's -6.5 i do not understand how to get that answer (-6,5) the answer is 5√7
That is not a complete question???
The answer is: "42" .

Explanation:
_____________________________________
From the stem-and-leaf plot provided, we can write the following values from the data set, from least to greatest:
____________________________________
{15, 18, 46, 50, 50, 50, 50, 57} ;
____________________________________
To calculate the mean, we take the sum of all the values in the data set; that is, we add up all the values in the data set; and we divide that sum total by the number of values in the data set.
In our data set, we have EIGHT (8) values.
To calculate the mean:
_________________________
{15 + 18 + 46 + 50 + 50 + 50 + 50 + 57} / 8 = the mean {our answer}.
________________________________________________________
→ {15 + 18 + 46 + 50 + 50 + 50 + 50 + 57} / 8 =
→ {336} / 8 = 42 .

The answer is: " 42 " .

Answer:
Step-by-step explanation:
Given a basket, the probability of a ball to end there is (because there are m baskets).
Then, the probability of a ball to end in other basket is .
Finally, the probability of the basket to remain empty after n throws is
This last is because, given n independets events with probability p, the probability for all of them to happen is . In this case
Answer:
(0,7)
Step-by-step explanation:
(I'm assuming you have to solve the system of equations)
3x -10y = -70
4x +9y = 63
Solving by elimination.
Eliminate x first, so we need the x-component of both equations to have the same number but opposite sign. So i'm going to multiply the first by -4 and the second by +3.
//I could have also done +3 to first and -4 to second
-4(3x -10y = -70)
3(4x +9y = 63)
-12x +40y = 280
12x +27y = 189
Add the equations //x's cancel
67y = 469
Divide both side by 67, y=7
Plug in y into any original equation to solve to x
3x - 10(7) = -70
3x -70 = -70
3x = 0
x=0
