What is 9.286 as a mixed number
marshall27 [118]
9.286 

[To change to mixed number, count the number of digits after the decimal point. There are 3 digits, so the denominator will be 1000]

9.286 = 9 \frac{286}{1000}

Then we simplify the fraction
(286 ÷ 2)/(1000÷2) = 143/500

Therefore,
9.286 = 9 \frac{286}{1000}
9.286 = 9 \frac{143}{500}

pogonyaev

Answer:

51,111%

Step-by-step explanation:

We know that 45% have a dog but no cat.  While 23% have both a dog and a cat.

Then Pr(X has cat|X has dog) = Pr(X has dog and cat)/Pr(X has dog)

= Pr(X has dog and cat)/Pr(X has dog) = 0.23/0.45 = 0.51 ≈ 51,111%

The probability that a student’s family owns a cat if the family owns a dog is 51,111%
