The time it takes me to wash the dishes is uniformly distributed between 5 minutes and 12 minutes. What is the probability that

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

How does knowing the double 6+6=12 help you solve the near double 6+7=13

forsale [732]

Answer:

6 + 7 = 13

Step-by-step explanation:

We are given the following information in the question:

We know that

$6 + 6 = 12$

We need this information to evaluate

$6+7$

The evaluation can be done with the help of using associative property and distributive property.

Associative property: (a + b) + c = a + (b + c)

The evaluation can be shown as:

$6 + 7\\= 6 + 6 + 1\\=(6 + 6) + 1\\= 12 + 1\\=13$

Monique randomly surveyed 30 students from

Naily [24]

Answer:

522

Step-by-step explanation:

Find the percent of students in her class that have a dog or cat:

Set up a proportion: $\frac{18}{30} = \frac{x}{100}$
Cross multiply, then divide: 18 × 100 = 1800, 1800 ÷ 30 = 60
So, 60% have a dog or cat

Find 60% of the total amount of students in Monique's school:

60% of 870 = $\frac{60}{100}$ × $\frac{870}{1}$
$\frac{60}{100}$ × $\frac{870}{1} = \frac{52200}{100}$
$\frac{52200}{100} = \frac{522}{1} = 522$

I hope this helps!
