Answer:
X=-12
Step-by-step explanation:
9-16-5=X
-12=X
X=-12
To find the first blank, just replace x in the equation with 12 and solve.
a(12) = 50 - 1.25(12) = your answer for blank 1
For blank 2: because x represents the number of apps on her phone, and x is given 12 for this problem, she bought 12 apps.
For blank 3: You would mention how many apps she got twice, so not the first option or the third option. It should be the answer from the first blank because the equation represents how much money is in her account.
All you have to do to solve this problem is insert the integer for the variable in the expression.
So, instead of having the variable expression r+s+t, you would have the integer expression 26-12-8.
If you combine 26 and -12, you get 14-8.
If you subtract 14-8, you get 6.
Your final answer is a. 6.
I think the value of y would be 9
because if you put 3 in place of x the equation would be
6.4(3)+2.8y then you would simplify it to 19.2+2.8y
19.2-44.4=25.5
25.2/2.8=9 which is the value of y
answer=9
Answer:
0.3950
Step-by-step explanation:
Any team team will win the championship with probability 63% that is
P(W)=0.63
when teams win the championship, they win the first game of the series 72% of the time that is
P(F|W)=0.72
When they lose the championship, they win the first game 27% of the time.
P(F|W')=0.27
The probability that they will win the World Series when the first game is over and your team has lost that is
P(W|F')
Now, By Bayes theorem
![\begin{array}{l}P\left(W | F^{\prime}\right)=\frac{P\left(F^{\prime} | W\right) P(W)}{P\left(F^{\prime} | W\right) P(W)+P\left(F^{\prime} | W^{\prime}\right) P\left(W^{\prime}\right)} \\\quad=\frac{[1-P(F | W)] P(W)}{[1-P(F | W)] P(W)+\left[1-P\left(F | W^{\prime}\right)\right][1-P(W)]} \\\quad=\frac{[1-0.72] \times 0.63}{[1-0.72] \times 0.63+[1-0.27][1-0.63]} \\\quad=\frac{0.28\times 0.63}{0.28\times 0.63+0.73 \times 0.37} \\=0.3950\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bl%7D%3C%2Fp%3E%3Cp%3EP%5Cleft%28W%20%7C%20F%5E%7B%5Cprime%7D%5Cright%29%3D%5Cfrac%7BP%5Cleft%28F%5E%7B%5Cprime%7D%20%7C%20W%5Cright%29%20P%28W%29%7D%7BP%5Cleft%28F%5E%7B%5Cprime%7D%20%7C%20W%5Cright%29%20P%28W%29%2BP%5Cleft%28F%5E%7B%5Cprime%7D%20%7C%20W%5E%7B%5Cprime%7D%5Cright%29%20P%5Cleft%28W%5E%7B%5Cprime%7D%5Cright%29%7D%20%5C%5C%3C%2Fp%3E%3Cp%3E%5Cquad%3D%5Cfrac%7B%5B1-P%28F%20%7C%20W%29%5D%20P%28W%29%7D%7B%5B1-P%28F%20%7C%20W%29%5D%20P%28W%29%2B%5Cleft%5B1-P%5Cleft%28F%20%7C%20W%5E%7B%5Cprime%7D%5Cright%29%5Cright%5D%5B1-P%28W%29%5D%7D%20%5C%5C%3C%2Fp%3E%3Cp%3E%5Cquad%3D%5Cfrac%7B%5B1-0.72%5D%20%5Ctimes%200.63%7D%7B%5B1-0.72%5D%20%5Ctimes%200.63%2B%5B1-0.27%5D%5B1-0.63%5D%7D%20%5C%5C%3C%2Fp%3E%3Cp%3E%5Cquad%3D%5Cfrac%7B0.28%5Ctimes%200.63%7D%7B0.28%5Ctimes%200.63%2B0.73%20%5Ctimes%200.37%7D%20%5C%5C%3C%2Fp%3E%3Cp%3E%3D0.3950%5Cend%7Barray%7D)
