a carnival booth duck game offer cash prizes. the booth at 75 plastic ducks floating around in a wading pool. 4 ducks have a green stars on the underside, and you win $10 for selecting a duck with a green star. it costs $1 to select a duck. is this a fair game?
Answers
Answer:
No, it is not fair
Step-by-step explanation:
Here, we want to check if this is a fair game
To win a sum, a duck with a green star on the underside must be selected
The number of ducks with this is 4 out of 75
The probability of selecting one is 4/75
The expected value of selecting is ;
4/75 * 10 = 0.5333
The cost of selecting a duck is $1
The probability that a duck that wins will not be selected is 71/75 which at a price of $1 is 0.9467
Since the price to lose and the amount to win is not the same, then the game is not fair

A video posted on the internet is becoming very popular, and the total number of views is increasing by 40% every hour. If the video currently has 74,300 views, how many views will it have in 9 hours?
Answers
Answer:
74304 approx.Step-by-step explanation:
Step one:
given data
current view of the video is marked at =74300
the rate of increase is 40%
let the number of hours be x
and let the total views be y
hence the linear function for the total is
y=0.4x+74300
Required is the value of y when x=9
Step two:
substitute x=9
y=0.4(9)+74300
y=3.6+74300
y=74303.6
y=74304 approx.
In a lab experiment, 100 bacteria are placed in a petri dish. The conditions are such that the number of bacteria is able to double every 26 hours. How long would it be, to the nearest tenth of an hour, until there are 168 bacteria present?
Answers
9514 1404 393
Answer:
19.5 hours
Step-by-step explanation:
The number in the dish at time t (in hours) can be described by ...
n(t) = 100·2^(t/26)
We want to find t such that ...
n(t) = 168
100·2^(t/26) = 168
2^(t/26) = 1.68 . . . . . . divide by 100
(t/26)log(2) = log(1.68) . . . . . take logarithms
t = 26·log(1.68)/log(2) ≈ 19.459992 . . . . divide by the coefficient of t
t ≈ 19.5 . . . hours
It would be about 19.5 hours until there are 168 bacteria.

A circle has a diameter of 32 m. What is its circumference?
Use 3.14 for it, and do not round your answer. Be sure to include the correct unit in your answer.
Answers
Answer:
[tex]C=32(3.14)=100.48\text{ meters}[/tex]
Step-by-step explanation:
We know that the circle has a diameter of 32 meters.
And we want to find its circumference.
The circumference of a circle is given by the formula:
[tex]C=\pi d[/tex]
Where d is the diameter.
So, we will substitute 32 for d and we will use 3.14 for π. Hence, our circumference will be:
[tex]C=32(3.14)=100.48\text{ meters}[/tex]
Answer:
100.48 m
Step-by-step explanation:
C=2(3.14)r
C=2(3.14)(16)
C= 100.48 m

Considerando las siguientes variables a = ancho y l = longitud, determina su valor, si se sabe que se cuenta con un rectángulo que tiene como perímetro 35 metros, y se sabe que el doble de su ancho es igual a 3 veces su longitud.
Answers
Answer:
La longitud = 7 metros
La anchor = 10.5 metros
Step-by-step explanation:
La fórmula para el perímetro de un rectángulo es
P = 2L + 2W
L = longitud
A = ancho
P = 35 metros
se sabe que el doble de su ancho es igual a 3 veces su largo.
2A = 3L
Ancho = 3L / 2 = 1.5L
Sustituimos 1.5L por W
35 = 2 L + 2 (1.5 L)
35 = 2L + 3L
35 = 5 litros
L = 35/5
L = 7 metros
Por lo tanto, la longitud = 7 metros
Recuerda
A = 1.5 L
A = 1.5 × 7
A = 10.5 metros
La anchor = 10.5 metros

A teacher buys 5 pizzas. Each slice is 1/8 of a pizza. How many slices are there in total?
1/40 slice
4 slices
20 slices
40 slices
Answers
Answer:
40 slices
Step-by-step explanation:
Each slice = 1/8 pizza
Pizza = 8 slices
5 pizza = 5 x 8 slices
5 pizza = 40 slices
The total number of slices in 5 pizzas if each slice is 1/8 of a pizza is 40 slices
Solving equationTotal pizza bought = 5Each slice = 1/8Total slices of pizza = Total pizza bought ÷ Each slice
= 5 ÷ 1/8
= 5 × 8/1
= 40 slices
Therefore, the total number of slices in 5 pizzas if each slice is 1/8 of a pizza is 40 slices

Bill is making accessories for the soccer team. He uses 777.35 inches of fabric on headbands for 32 players and 3 coaches. He also uses 301.76 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player?
Answers
Answer:
Fabric used on a headband for each player = 22.21 inches
Fabric used on a wristband for each player = 9.43 inches
Step-by-step explanation:
Let fabric used on each headband = [tex]h[/tex] inches
Let fabric used on each wristband = [tex]w[/tex] inches
Number of players for which headband is made = 32
Fabric used on 32 players = 32[tex]h[/tex] inches
Number of coaches for which headband is made = 3
Fabric used on 3 coaches = 3[tex]h[/tex] inches
As per question statement:
Total fabric used on headbands = 777.35 inches
[tex]32h + 3h = 777.35\\\Rightarrow 35h = 777.35 inches \\\Rightarrow h = 22.21\ inches[/tex]
Number of players for which wristband is made = 32
As per question statement:
Fabric used on wristbands = 301.76 inches
[tex]32w = 301.76\\\Rightarrow w = 9.43\ inches[/tex]
Therefore, the answer is:
Fabric used on a headband for each player = 22.21 inches
Fabric used on a wristband for each player = 9.43 inches
