Answer: Assuming you mean that the original cost was doubled and now equals $60, the camera costed $30. Assuming the camera's price has been doubled from $60, it is $120. The wording is a bit unclear, so I'm giving you both answers.
Step-by-step explanation: To find half of the price of $60, simply divide it by 2, which gives you $30.
Answer:
P(B|Y)=0.4
Step-by-step explanation:
We are given with a Venn diagram of a universe with 26 elements and two different outcomes: B and Y
And we are asked to find P(B|Y)
The formula for P(B|Y)= ![\frac{P(B\cap Y)}{P(Y)}](https://tex.z-dn.net/?f=%5Cfrac%7BP%28B%5Ccap%20Y%29%7D%7BP%28Y%29%7D)
From Venn diagram, ![P(B\cap Y)=\frac{n(B\cap Y)}{26} =\frac{8}{26} =\frac{4}{13}](https://tex.z-dn.net/?f=P%28B%5Ccap%20Y%29%3D%5Cfrac%7Bn%28B%5Ccap%20Y%29%7D%7B26%7D%20%3D%5Cfrac%7B8%7D%7B26%7D%20%3D%5Cfrac%7B4%7D%7B13%7D)
And P(Y)=![\frac{n(Y)}{26}=\frac{8+12}{26}= \frac{20}{26}= \frac{10}{13}](https://tex.z-dn.net/?f=%5Cfrac%7Bn%28Y%29%7D%7B26%7D%3D%5Cfrac%7B8%2B12%7D%7B26%7D%3D%20%5Cfrac%7B20%7D%7B26%7D%3D%20%5Cfrac%7B10%7D%7B13%7D)
Hence P(B|Y)=![\frac{(\frac{4}{13})}{\frac{10}{13}} =\frac{4}{10}=0.4](https://tex.z-dn.net/?f=%5Cfrac%7B%28%5Cfrac%7B4%7D%7B13%7D%29%7D%7B%5Cfrac%7B10%7D%7B13%7D%7D%20%3D%5Cfrac%7B4%7D%7B10%7D%3D0.4)

Step-by-step explanation:by the way I like ur pfp
Multiply 2 and -3 getting -6, so z+9=-6 -9 to -6 and the answer is -15
