Answer:
Two players of equal skill level each played one game a day for 50 days and their skill level did not change from day to day.
Step-by-step explanation:
(A) The probability of player winning the game depends on the skill level . If skill level increases the probability to win also increases. The probability of success (win) must remain constant for every trial (condition of binomial distribution), hence, this case cannot be modeled by a random binomial probability.
(B) Different skill levels means the probability of success differs between players, the probability of winning each game would differ between players, hence. X can not be a binomial random variable.
(C) Same explanation as B
(D) As both players have same skill set throughout the game, the probability of winning each of the n = 100 games is the cosnat; hence, X can be modeled as a binomial random variable
(E) Same explanation as B and C
For this case we have the following equation of a line:
To find the point of intersection with the x axis, we make y = 0:
We clear the value of "x":
So, the x-intercept of the line is 5.
To find the point of intersection with the y axis, we make x = 0:
We clear the value of "and":
So, the y-intercept of the line is 20.

Answer:
59.6 ft²
Step-by-step explanation:
The surface area of the pillow is the total area of the net.
The net is made up of 3 rectangles and 2 congruent triangles.
Area of a rectangle = width × length
Area of a triangle = 1/2 × base × height
<u>Rectangle 1</u> (left)
area = 4 × 5 = 20 ft²
<u>Rectangle 2</u> (middle)
area = 4 × 5.4 = 21.6 ft²
<u>Rectangle 3</u> (right)
area = 2 × 4 = 8 ft²
<u>Triangle</u>
area = 1/2 × 5 × 2 = 5 ft²
(Be careful here, as it is easy to use the wrong length for the base of the triangle. The base and height of the triangle are perpendicular, so at right angles to each other. Therefore, the base is 5ft and the height is 2ft)
Total area = rectangle 1 + rectangle 2 + rectangle 3 + 2 × triangle
= 20 + 21.6 + 8 + (2 × 5)
= 49.6 + 10
= 59.6 ft²
