Answer with Step-by-step explanation:
Since we have given that
Some students in my class use e-mail.
It is a type of 'E' statements.
Its negation should be No students in my class use e-mail.
Because if we use "Some students in my class do not use e-mail”.
It also implies some students in my class still use e-mail.
But negation contains only opposite of given statement.
So, Some students in my class do not use e-mail” is not true.
X 1 2 3 4
p(x) 0.40 0.20 0.15 ?
If the items are only 4. The total of the probability must be 1 or 100%
1 - 0.40 - 0.20 - 0.15 = 0.25
The probability of 4 is 0.25.
A cheesecake has equally sized slices. Each slice is a different flavor. The cheesecake has 12 slices.
<h3>What is the area of the circle?</h3>
The area of the circle is defined as the product of the pie and the square of the radius.
The area of the circle = πr²
In order to calculate the total area of the cheesecake, since it's a circle its area is given by:
cheesecake area = πr²
cheesecake area = π(10/2)² = π(5)²
cheesecake area = 25 π square inches
Therefore the number of slices is the ratio of the cheesecake total area by the area of each slice:
The number of slices = 25 π/(25 π/12)
The number of slices = 12
The cheesecake has 12 slices.
