People at the state fair were surveyed about which type of lemonade they preferred. The results are shown below:
Pink Lemonade: 156 males, 72 females
Yellow Lemonade: 104 males, 48 females
Answers
Answer
Step-by-step explanation:
You would require the table with the number of males and females who prefer either pink or yellow lemonade at the state fair.
Pink Lemonade Yellow Lemonade TOTAL
Male 156 104 260
Female 72 48 120
TOTAL 228 152 380
P(pink lemonade | female) = 72 / (48 + 72) = 72 / 120 = 0.6
P(pink lemonade) = (156 + 72) / (156 + 72 + 104 + 48) = 228 / 380 = 0.6
Therefore, The event "prefers pink lemonade" and "female" are independent because P(pink lemonade | female) = P(pink lemonade) = 0.6
Independents events are events that can happen independently on their own. Events A and B are independent if P(A|B) = P(A).
The "prefer pink" event and "female" event are independent because [tex]P(P|F) = P(P) = 0.6[/tex]
To do this, we make the following representations:
[tex]P \to[/tex] Pink Lemonade
[tex]Y \to[/tex] Yellow Lemonade
[tex]M \to[/tex] Male
[tex]F \to[/tex] Female
The "prefer pink" event and "female" event are independent if:
[tex]P(P|F) = P(P)[/tex]
[tex]P(P|F) \to[/tex] the probability that a selected person prefers pink provided that the person is female
[tex]P(P) \to[/tex] the probability that a selected person is female
P(P| F) is calculated as:
[tex]P(P| F) = \frac{n(P\ n\ F)}{n(F)}[/tex]
i.e. the number of females who prefers pink divided by the number of females
From the table, we have:
[tex]n(P\ n\ F) = 72[/tex]
[tex]n(F) = 72 + 48 =120[/tex]
So, the probability is:
[tex]P(P| F) = \frac{72}{120}[/tex]
[tex]P(P| F) = 0.6[/tex]
[tex]P(P)[/tex] is calculated as:
[tex]P(P) = \frac{n(P)}{Total}[/tex]
i.e. the all people who prefer pink divided by total number of people
From the table, we have:
[tex]n(P) = 156 + 72 = 228[/tex]
[tex]Total = 156 + 72 + 104 + 48 = 380[/tex]
So, the probability is:
[tex]P(P) = \frac{228}{380}[/tex]
[tex]P(P) = 0.6[/tex]
Recall that:
The "prefer pink" event and "female" event are independent if:
[tex]P(P|F) = P(P)[/tex]
And we have:
[tex]P(P| F) = 0.6[/tex]
[tex]P(P) = 0.6[/tex]
Hence, the events are independent because:
[tex]P(P|F) = P(P) = 0.6[/tex]
Option (a) is correct

Cecilia watched 1 2 of a movie in the morning, and she watched some more at night. By the end of the day, she still had 1 3 of the movie left to watch. How much of the movie did Cecilia watch at night?
Answers
Answer: 1/6 of the movie.
Step-by-step explanation:
First, she watches 1/2 of the movie.
This means that if the movie lasts N minutes, the time left is:
N - (1/2)*N = (1/2)*N.
Then she watches another part of the movie, let's call it as a*N, and after that, she has 1/3 of the movie left, we can write this situation as:
(1/2)*N - a*N = (1/3)*N
we can divide by N in both sides to get
(1/2) - a = (1/3)
(1/2) - (1/3) = a
3/6 - 2/6 = a
1/6 = a
So we can conclude that she watched 1/6 of the movie at night.

Leon is using an area model to multiply 38×14. First, he makes a rectangle that is 38 units long and 14 units tall. Then, he breaks it into smaller parts using place value to make it easier to multiply. Use the drop-down menus to show the area of each part.
Answers
Answer:
300, 120, 80 and 32 respectively.
Step-by-step explanation:
To break it down for easy multiplication, write
38 as 30 + 8
14 as 10 + 4
Now let's multiply
(30 + 8)(10 + 4) = 300 + 120 + 80 + 32
So the areas of each part would be
300, 120, 80 and 32 respectively.

A car rental offers two options for renting a car. Plan A costs $200 per week plus $0.35 for each mile driven during that week. Plan B costs $180 per week plus $0.55 for each mile driven that week. How many miles of driving would result in both plans costing the same amount for that week
Answers
Answer:
100 miles
Step-by-step explanation:
Two plans are being offered for the renting of cars.
Plan A:
Cost per week = $200
Cost for each mile = $0.35
Plan B:
Cost per week = $180
Cost for each mile = $0.55
To find:
Number of miles for which the cost is same ?
Solution:
Let the number of miles driven so that the cost becomes the same = [tex]m[/tex] miles
First of all, let us find the cost for each plan as per [tex]m[/tex] miles.
Cost as per plan A = Cost per week + Cost for [tex]m[/tex] miles = $200 + $0.35[tex]m[/tex]
Cost as per plan B = Cost per week + Cost for [tex]m[/tex] miles = $180 + $0.55[tex]m[/tex]
Now, putting both the costs equal to find the value of [tex]m[/tex]:
[tex]200 +0.35m = 180 +0.55m\\\Rightarrow 20 = 0.20m\\\Rightarrow m = \bold{100\ miles}[/tex]
Therefore, after 100 miles the cost from each plan will be the same.
A middle school took all of its 6th grade students on a field trip to see a play at a theater that has 3100 seats. The students left 1395 seats vacant. What percentage of the seats in the theater were filled by the 6th graders on the trip?
Answers
Answer: 55% of the seats in the theater were filled by the 6th graders on the trip.
Step-by-step explanation:
Given: Total seats = 3100
Seats vacant= 1395
Seats occupied by 6th graders = 3100-1395 = 1705
The percentage of the seats in the theater were filled by the 6th graders on the trip = [tex]\dfrac{\text{Seats occupied by 6th graders}}{\text{Total seats}}\times100[/tex]
[tex]=\dfrac{1705}{3100}\times100\\\\= 55\%[/tex]
Hence, 55% of the seats in the theater were filled by the 6th graders on the trip.
