Step-by-step explanation:
4x+6+3=-8
4x+9=-8
-9 -9
4x=-17
÷4 ÷4
X=-17⁄4
If you are asking for the price, then the jeans would cost $32
Question 4:
OOOOOHHH a breakthrough! I was confused when I read this question but now I get it!
Okay when dividing this equation I would do this
5^4
25
Since 25 is 5 x 5 I would mark it as 5^2, and then I can subtract!
5^4
5^2 =
5^2
If you do it like this then it would be the first choice.
a. Use the inclusion/exclusion principle.
![P(A_1\cap A_2)=P(A_1)+P(A_2)-P(A_1\cup A_2)=0.55+0.65-0.80=0.40](https://tex.z-dn.net/?f=P%28A_1%5Ccap%20A_2%29%3DP%28A_1%29%2BP%28A_2%29-P%28A_1%5Ccup%20A_2%29%3D0.55%2B0.65-0.80%3D0.40)
b. By definition of conditional probability,
![P(A_2\mid A_3)=\dfrac{P(A_2\cap A_3)}{P(A_3)}=\dfrac{0.50}{0.70}\approx0.7143](https://tex.z-dn.net/?f=P%28A_2%5Cmid%20A_3%29%3D%5Cdfrac%7BP%28A_2%5Ccap%20A_3%29%7D%7BP%28A_3%29%7D%3D%5Cdfrac%7B0.50%7D%7B0.70%7D%5Capprox0.7143)
