How is 10 2/3 written as a decimal to the nearest hundred
expeople1 [14]

Answer:

10.67

Step-by-step explanation:

The 10 stays as it is.  The 2/3 is approximated by 0.67 (to the nearest hundredth).  Thus, we have 10.67 to the nearest hundredth.

If the slope of PQ is 2/3 and the slope of QR is-1/2 , find the slope of SR so that PQRS is a parallelogram.

Please help and explain how you solved it. Thanks.

Answer:

This is 0.14 to the nearest hundredth

Step-by-step explanation:

Firstly we list the parameters;

Drive to school = 40

Take the bus = 50

Walk = 10

Sophomore = 30

Junior = 35

Senior = 35

Total number of students in sample is 100

Let W be the event that a student walked to school

So P(w) = 10/100 = 0.1

Let S be the event that a student is a senior

P(S) = 35/100 = 0.35

The probability we want to calculate can be said to be;

Probability that a student walked to school given that he is a senior

This can be represented and calculated as follows;

P( w| s) = P( w n s) / P(s)

w n s is the probability that a student walked to school and he is a senior

We need to know the number of seniors who walked to school

From the table, this is 5/100 = 0.05

So the Conditional probability is as follows;

P(W | S ) = 0.05/0.35 = 0.1429

To the nearest hundredth, that is 0.14
