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 
The probability she passes the second course is 0.7.
This means that 
The probability she passes at least one of the courses is 0.79.
This means that 
a. What is the probability she passes both courses
This is
.
We use the following relation:

So

0.58 = 58% probability she passes both courses
Answer: A. 40%
Step-by-step explanation:
to find the percentage decrease, first you have to subtract $6,300 from $10,500, which equals $4,200. This is the amount decreased from the price of the car. Then, to find the percentage that $4,200 is to $10,500, you have to divide 4,200 by 10,500. This should give you 0.4, the percentage is this number multiplied by 100. This should give you the number 40, which means that the percentage decrease of the price of the car; 40%.
Corrine collected 11 1/8 geodes or 89/11 geodes.
Ellen collected 4 5/8 geodes or 27/8 geodes.
Leonda collected 3 3/4 geodes or 15/4 geodes.
Ellen and Leonda collected a total of 27/8 + 15/4 geodes.
They collected 27+30/8 = 57/8 geodes.
Corrine collected 89/11 - 57/8 more geodes.
She collected (89*8 - 57*11)/88 = 85/88 geodes more.
The answer is 65.9 because the place right after the decimal is the tenths place
Answer:
3 x 5
Step-by-step explanation:
The dimension of a matrix is normally represented in form of:
<u>number of rows</u> x <u>number of columns</u>
In the given matrix, there are 3 rows and 5 columns.
=> The dimension of this matrix is 3 x 5
=> Option D is correct
Hope this helps!
