The answer is...: x = 10/9
Answer:
Pr(only one of them will pass the driving test) = 0.38
Step-by-step explanation:
The probability that Ben will pass = 0.8
Let Pr = pribability
Pr(Ben pass) = 0.8
Pr(Ben fail) = 1 - Pr(Ben pass) = 1-0.8
Pr(Ben fail) = 0.2
The probability that Tom will pass = 0.7
Pr (Tom pass) = 0.7
Pr (Tom fail) = 1 - Pr (Tom pass) = 1-0.7
Pr (Tom fail) = 0.3
Pr(only one pass) = Pr(Ben pass and Tom fail) + Pr (Tom pass and Ben fail)
Pr(only one pass) = (0.8 × 0.3) + (0.7 × 0.2)
Pr(only one pass) = 0.24 + 0.14
Pr(only one pass) = 0.38
Answer:
X=130
Step-by-step explanation:
Since the two sides are equal, the two angles are equal.
x=180-25-25
x=130
Answer:

Step-by-step explanation:
According to the Definition of Rational Exponents, use this formula to rewrite this as an exponential expression:
![a^{\frac{m}{n}} = \sqrt[n]{a}^{m}](https://tex.z-dn.net/?f=a%5E%7B%5Cfrac%7Bm%7D%7Bn%7D%7D%20%3D%20%5Csqrt%5Bn%5D%7Ba%7D%5E%7Bm%7D)
NOTE: Since we have exponents in our radical, we have to multiply all exponents by one-half, since raising something to its <em>half power</em> is the exact same as taking the <em>square root</em> of something:
![[{n}^{3}{p}^{4}]^{\frac{1}{2}} = {n}^{1\frac{1}{2}}{p}^{2}](https://tex.z-dn.net/?f=%5B%7Bn%7D%5E%7B3%7D%7Bp%7D%5E%7B4%7D%5D%5E%7B%5Cfrac%7B1%7D%7B2%7D%7D%20%3D%20%7Bn%7D%5E%7B1%5Cfrac%7B1%7D%7B2%7D%7D%7Bp%7D%5E%7B2%7D)
* Do not forget to remove the radical in the beginning because you are once again, rewriting this as an exponential expression.
