How many did he have at first.
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
Hi there! The answer is -2.
We can find the slope of a formula by using the following formula:

x2 and y2 don't mean squared, but the x and y coordinate of our second point.
First we need to find two points on the line. Ijn this particular case we have (-3, 3) and (1, -5). Now we can fill in the formula.

Therefore, the third answer is correct.
~ Hope this helps you!
Answer:1800 words
Step-by-step explanation:
Multiply how many words per minute she types by how many minutes she types. In this case 60x30=?. The easy way to do this is drop the 2 zeros and do 6x3=18. In the original equation we dropped the 2 zeros. Now we add them back on the back of the 18 and get 1800.
