What’s 45 divided by 14.04

Vladimir79 [104]

Answer:

3.205

Step-by-step explanation:

convert the decimal number to a fraction

$45 \div \frac{351}{25}$

To divide by fraction, multiply by the reciprocal of that fraction

$45 \times \frac{25}{351}$

Reduce the numbers with the greatest common divisor 9

$5 \times \frac{25}{39}$

Calculate the product

$\frac{125}{39}$

Now turn it to a decimal which will be

$3.20513$

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
