Answer:

0.74

Step-by-step explanation:

A <u>tree diagram</u> is a visual way of showing combinations of <u>two or more events</u>. The outcome of each branch is labelled at the end of the branch line and its probability is written alongside the branch.

To calculate the probabilities of each combination, follow the branches and <u>multiply the probabilities</u> together.

There are two possible combinations to get a final outcome of D:

  • A and D = 0.6 × 0.7 = 0.42
  • B and D = 0.4 × 0.8 = 0.32

Therefore, the probability of D is:

⇒ P(D) = P(A and D) <u>OR</u> P(B and D):

⇒ P(D) = 0.42 + 0.32

⇒ P(D) = 0.74

What is the quotient of -42 and 7?
viktelen [127]
When you find the quotient of two numbers it means you're dividing them. So, you can solve this by dividing -42 by 7.
Seven will go into forty-two 6 times, but whenever you divide a negative number by a positive number, the answer will also be negative. So, the quotient of -42 and 7 is -6.

What is an equation of the line that passes through the point (3,-1) and (8, 9)?
Evgesh-ka [11]

Answer:

4) y = 2x - 7

Step-by-step explanation:

First we have to find the slope by using the following formula....

let (3, - 1) be (x_{1}, y_{1} ), let (8, 9) be (x_{2} ,y_{2} ), and m be the slope, then....

m = \frac{y_{2} -y_{1} }{x_{2} - x_{1} } = \frac{9 + 1}{8 - 3} = \frac{10}{5} = 2

Now that we know the slope we can find the equation of the function by using point-slope for of the function which look like this.....

y -y_{1} = m(x - x_{1} )\\y + 1 = 2(x - 3)\\y + 1 = 2x - 6\\y = 2x - 7
