Wren and Jenni are reading the same book. Wren is on page 12 and reads 4 pages every night. Jenni is on page 4 and reads 5 pages every night.

Answers

The equation represents the pages after x nights.

Wren:

12 + 4x

Jenni:

4 + 5x

After 8 nights Wren and Jenni will be on the samepage of the book.

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equalsign.

We have,

Wren and Jenni are reading the same book.

Wren is on page 12 and reads 4 pages every night.

This can be written as an equation.

12 + 4x _____(1)

x = number of nights.

Jenni is on page 4 and reads 5 pages every night.

This can be written as an equation.

4 + 5x _______(2)

x = number of nights.

The number of nights after which both of them will be on the samepage.

From (1) and (2) we get,

12 + 4x = 4 + 5x

12 - 4 = 5x - 4x

8 = x

x = 8

Thus,

The equation represents the pages after x nights.

Wren:

12 + 4x

Jenni:

4 + 5x

After 8 nights Wren and Jenni will be on the samepage of the book.

The standard normal curve shown here is a probability density curve for a continuous random variable. This means that the area underneath the entire curve is 1. What is the area of the shaded region between the two z-scores indicated in the diagram?

Answers

Answer with explanation:

The Curve given here is a probability density curve for a continuous random variable.

Area under the entire region of the curve = 1

Using the Standard normal table to obtain area occupied when Z values are given

Area of the normal curve, when ,Z =0.88, is =0.8106

Area occupied by normal curve ,when Z= -1.26, is =0.1038

So, Area of shaded Region

     Z_(0.88)-Z_(-1.26)=0.8106-0.1038\n\n=0.7068

Option D:→ 0.7068    

I used one of the statistical functions on my trusty TI-83 Plus calculator:


normcdf(-1.26, 0.88) = 0.707


Note that this is, as expected, between 0 and 1.
