Answer: 54.29%
Step-by-step explanation:
Given: The probability that they will win both games is 38%.
i.e. P( both games will win) =0.38
The probability that they will win just the first game is 70%.
P(first game will win) = 0.70
To find : P(second game will win| first game will win)
Using formula: 
So, P(second game will win| first game will win) = 
Hence, the required probability = 54.29%
Answer:
4x+5y=20
Step-by-step explanation:
bc if u subtract your 4x from both sides
then u should end up with 5y= -4x+20
then u divide the 5 from everything
then you end up with y= -4/5x+4
Answer:
The residual of the point 
in the equation 
is 
Step-by-step explanation:
We have been given point where 
.
Now the equation is .
Plugging the value of in the equation of ,
we have to find the predicted value of y and 
.
So y predicted 
.
To find the residual point we have to subtract the actual value from the predicted value.
As actual value of 
along with the points .
Residual point = Actual value - Predicted value.
So the residual for the point is 
.

11x+5y=20
2x+5y=-25
multiply the second equation by - 1 and add the result with the first equation:
11x + 5y = 20
- 2x - 5y = 25
-------------------
9x = 45
=> x = 45 / 9
=> x = 5
Replace in </span><span>2x+5y=-25
=> 2(5) + 5y = - 25
5y = - 25 - 10
5y = - 35
y = - 35 / 5
y = - 7
2)
3x+7y=-21
3x-7y=63</span>
Add the two equations:
3x + 3x + 0 = - 21 + 63
6x = 42
=> x = 42 / 6
=> x = 7
Replace in <span>3x-7y=63
3(7) - 7y = 63
=> 7y = 21 - 63
=-> 7y = - 42
=> y = - 42 / 6
=> y = - 7</span>
Answer:
Four tickets and four snacks comes to a total of $74.00
If she buys x snacks, that cost is 4.50x. so the total for 4 tickets and unknown snacks is 4(14) + 4.5x
Step-by-step explanation:
Nicole + 3 kids is 4 tickets times $14. 4×14=56. Add the snacks. 4×4.50=18. $56+$18=$74
