Answer:
The red team is expected to win 6 fewer games than the blue team
Step-by-step explanation:
In this question, we are concerned with calculating the number of games the red team is expected to win less than what the blue team will win, given the probability of wining of each of the teams and the total number of games
To calculate the total number of games each team is expected to win, what we do is to multiply the probability of wining of each of the teams by the total number of games
For the red team , the probability of wining P(r) = 0.3
The total number of games expected to be won is mathematically equal to 0.3 × 120 = 36 games
For the blue team , the probability of wining P(b) = 0.35
The total number of games expected to be won is mathematically equal to 0.35 × 120 = 42 games
The number of games fewer that the red team is expected to win = number of games expected to be won by the blue team - number of games expected to be won by the red team = 42 games - 36 games = 6 games
I think it’s B I am not sure if it’s wrong sorry :(
To solve for the surface area of the pyramid, we make use
of the formula:
A= l w + l [sqrt ((w / 2)^2 + h^2)] + w [sqrt ((l / 2)^2 + h^2))
where,
l and w are the base of the pyramid = 100 mm
h is the height of the pyramid = 75 mm
Substituting the given values into the equation:
A= 100 * 100 + 100 [sqrt ((100 / 2)^2 + 75^2)] + 100 [sqrt ((100
/ 2)^2 + 75^2))
A = 10,000 + 100 (sqrt 2575) + 100 (sqrt 2575)
A = 20,148.90 mm^2
Therefore the surface area of the pyramid is about 20,149
mm^2.
Klye would receive $0.77 back as change. You have to subtract $20.00 - $19.23
