The sum of two numbers is 48.<br>the second number is seven times the first number

dusya [7]

Answer:

$\huge\boxed{\sf x =6,\ y = 42}$

Step-by-step explanation:

Let the numbers be x and y

<h3>Given condition:</h3>

x + y = 48 --------(1)

y = 7x -------------(2)

Put Eq. (2) in (1)

x + 7x = 48

8x = 48

Divide 8 to both sides

x = 48/8

Put x = 6 in Eq. (2)

y = 7 (6)

$\rule[225]{225}{2}$

A and B are independent events. P(S) = 0.40 and P(B) = 0.30. What is P(A and B)

n200080 [17]

The value of the probability P(A and B) is 0.12

<h3>How to determine the probability?</h3>

The given parameters are

P(A) = 0.40

P(B) = 0.30

Given that the events are independent events;, we have:

P(A and B) = P(A) * P(B)

So, we have:

P(A and B) = 0.40 * 0.30

Evaluate

P(A and B) = 0.12

Hence, the value of the probability P(A and B) is 0.12
