Answer:
The expected value of the number of spades are = 4.25
Step-by-step explanation:
As per the question,
W know that in a standard deck of 52 playing card, there are 4 suits, and each suit have 13 playing card.
Since, we know that
Therefore,
Probability of any random card being a spade is
So the expected number of spades we draw are
Hence, the expected value of the number of spades are = 4.25
The first step to solve this problem, you have to compute
first for the total number of students:
6 math classes x 27 students per class = 162 students
Now, you know that there are 162 students all in all in the
school. The next step is to compute for the total cost of both the book and the
calculator per student.
$45.10 (Book) + $57.80 (Calculator) = $102.90 (total cost
per student)
To compute for the total cost that the school will pay, you
have to multiply the total cost per student to the number of students in
school.
$102.90 per student x 162 students = $16,669.80
Therefore, the total cost the school will pay is $16,669.80.
Answer:
She has 100 ounces.
Step-by-step explanation:
Since one bag has 8 apples, two of the bags have 8 apples and the one half bag of apples has 4 apples.
Then, since each apple weighs 5 ounces you multiply:
Equation:
= 2 1/2 × 8
= 5/2 × 8
= 40/2
= 20
20 x 5 = 100
Answer: 15x - 12
Steps: 3 (5x - 4)
3 x 5x - 3 x 4
15x - 3 x 4
15x - 12
You would use the slope equation, (y1-y2)/(x1-x2)
plug in the y coordinates and the x coordinates and you'll get:
-1/7
