GalinKa [24]

Answer:

0.2857

Step-by-step explanation:

We define the time it takes to do these dishes to be uniformly distributed between the time 5 minutes and 12 minutes.

a = 5 minutes

b = 12 minutes

Probability of tonight's dish washing being between 6 and 8 minutes

P(6<X<8)

= 8-6/b-a

= 2/12-5

= 2/7

= 0.2857

The probability it will be better 6 and 8 minutes is therefore 0.2857

What is 12.95p=44 simplified to its lowest value
goblinko [34]

\huge \boxed{\mathbb{QUESTION} \downarrow}

  • What is 12.95p=44 simplified to its lowest value?

\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}

\sf \: 12.95p = 44

Divide both sides by 12.95.

\sf \: p=\frac{44}{12.95}  \\

Expand 44/12.95 by multiplying both the numerator and denominator by 100.

\sf \: p=\frac{4400}{1295}  \\

Reduce the fraction 4400/1295 to its lowest terms by extracting and cancelling out 5.

\boxed{ \boxed{  \bf p = \frac{880}{259} = 3\frac{103}{259} \approx 3.39}}
