1. I think the underlined number is 2. So It will be hundredths.

2. (8 x 100) + (6 x 10) + (3 x 1) + (1/10) + (4/100) + (1/1000)

Or 800 + 60 + 3 + 0.1 + 0.04 + 0.001

A college student is taking two courses. The probability she passes the first course is 0.67. The probability she passes the sec

andrezito [222]

Answer:

0.58 = 58% probability she passes both courses

Step-by-step explanation:

We can solve this question treating the probabilities as a Venn set.

I am going to say that:

Event A: She passes the first course.

Event B: She passes the second course.

The probability she passes the first course is 0.67.

This means that $P(A) = 0.67$

The probability she passes the second course is 0.7.

This means that $P(B) = 0.7$

The probability she passes at least one of the courses is 0.79.

This means that $P(A \cup B) = 0.79$

a. What is the probability she passes both courses

This is $P(A \cap B)$ .

We use the following relation:

$P(A \cup B) = P(A) + P(B) - P(A \cap B)$

$P(A \cap B) = P(A) + P(B) - P(A \cup B) = 0.67 + 0.7 - 0.79 = 0.58$

0.58 = 58% probability she passes both courses

A rectangular prism measures 7.5cm by 12cm by 15.5 cm what is the volume

Sonbull [250]

Given = rectangular prism of measure 7.5 cm by 12 cm by 15.5 cm.

i.e length = 7.5 cm

breadth = 12 cm

height = 15.5 cm

Find out volume of the rectangular prism.

To proof -

Formula

Volume of the rectangular prism = length× breadth× height

= 7.5× 12× 15.5 cm³

= 1395 cm³

The volume ofthe rectangular prism become 1395 cm³.

Hence proved
