Answer: p = 0.56
Step-by-step explanation: from the question, probability she passed the first course = 0.7
Probability she passed the second course = 0.8
Probability she passes both courses means probability she passes the first course "and" probability she passes the second course.
Probability she pass both courses = 0.7 * 0.8 = 0.56
Note that "and" in probability means multiplication.

<h2><u>
Step-by-step explanation:</u></h2>
If 4 of Paiges' marbles are green, then we would write this as the ratio
<u>4:16</u>, or <u>1:4</u>
This means that for every green marble she has, she has 4 total marbles
Therefore, if Natalie has 10 green marbles, we would multiply this by 4 to get a total of <u>40 marbles.</u>
Answer:
15500 pounds
Step-by-step explanation:
The weight of one load is 4 tons and the weight of other load is 7500 pounds.
We know that, 1 ton = 2000 pounds
4 tons = 8000 pounds
Total weight = 8000 pounds + 7500 pounds
Total weight = 15500 pounds
So, the total weight of sand is 15500 pounds.
