Answer:

Option A- One

Step-by-step explanation:

Given that : The sides of the triangle measuring 6cm, 2cm and 7cm.

We are using : Triangle inequality

The sum of the length of the two sides should be greater than the length of the third side.

So, when we apply this theorem in 6cm,2cm and 7cm

6+2=8>7 , 7+2=9>6 , 7+6=13>2

It satisfy all three possible sets.

Therefore, the given values follows the triangle inequality.

Hence one triangle can be formed.

Therefore, option A is correct.

Step-by-step explanation:

Given

See attachment for chart

Required

Number of off days

To do this, we simply calculate the expected value of the chart.

This is calculated as:

$E(x) = \sum x * f$

Where

x = days

f = chances

So, we have:

$E(x) = 0* 0.3 + 1 *0.2 + 2 * 0.25 + 3 * 0.2 + 4 * 0.02 + 5 * 0.01 + 6 * 0.01 + 7 * 0.01$

$E(x) = 1.56$

$E(x) \approx 2$

A book is in the shape of a right rectangular prism. It measures 8 1/2 inches tall, 7 inches wide, and 2 1/2 inches thick. What

Alenkasestr [34]

Hello!

The formula for volume of a rectangular prism is:

V = lwh

Let's convert the dimensions to decimals, and then use the formula to solve.

8 1/2 = 8.5 as a decimal.

7 = 7 as a decimal.

2 1/2 = 2.5 as a decimal.

Multiply:

V = 8.5 × 7 × 2.5

V = 59.5 × 2.5

V = 148.75

148.75 = 148 3/4 as a fraction because if you convert 3/4 to a decimal by dividing the numerator by the denominator, it equals 0.75.

ANSWER:

The volume of the book is 148 3/4 inches cubed.
