Answer:
15 / 62
Step-by-step explanation:
Since there 32 students, of which 20 are male, the probability of selecting a student and them being male first is 20/32.
The probability of selecting another student and they are female is 12/31, because the male student is counted out of the selection because he is already picked.
This makes the probability 20/32 x 12/31 = 15 / 62
What is the sum of -4 1/2 + 3 1/4?

Answer:
We can see from the table that 1 km is exactly half way between 2 and 3 laps. So it will take 2.5 laps to run 1 km.
Since it takes Angel 2 minutes to run 1 lap, she will take
2.5 laps1 km⋅2 minutes1 lap=5 minutes1 km.
So it takes Angel 5 minutes to run 1 km.
Since it takes Jayden 5 minutes to runs 3 laps, she runs 1 lap in 53 minutes. Thus, it takes Jayden
2.5 laps1 km⋅5 minutes3 laps=52⋅53 minutes/km=256 minutes/km=416 minutes/km.
So it takes Jayden 416 minutes to run 1 km.

i actually dont know what the answer-answer is but i think this will help alot.
Answer:
Step-by-step explanation:
Distance traveled in 2 minutes by Angel = 2/5 kilo meter
Distance traveled in 1 minute by Angel = [tex]\frac{2}{5}[/tex] ÷ 2
[tex]=\frac{2}{5}*\frac{1}{2}[/tex]
= 1/5 kilometer

I learned how to find the area of a triangle with 2 numbers (0.5*b*h), but how do you find the area with 4 numbers?
Answer:
area =12
Step-by-step explanation: you don't need to use all 4 numbers just used the base which is 8 then times it with 3 which gives you 24 then divided it by 2 which gives you 12.
Answer:
Area=12
Step-by-step explanation:
You take the height which is 3 and multiply it by the base which is 8. Then you get 24 and divide it by 2 which gives you 12.

Answer: A is yes. B is no, C is yes
Step-by-step explanation: The reason A is yes, is because the terms are 27b, 12b and 4 because they are separated. The reason B is no, is because the like terms are 27b and 12b because their variables are alike. The reason C is yes, is because 27b+12b=39b+4 is an équation simplified.
Andre is making paper cranes to decorate for a party. He plans to make one large paper
crane for a centerpiece and several smaller paper cranes to put around the table. It takes
Andre 10 minutes to make the centerpiece and 3 minutes to make each small crane. He will
only have 30 minutes to make the paper cranes once he gets home.
1. Andre wrote the inequality to plan his time. Describe what , , 10,
and 30 represent in this inequality.
2. Solve Andre’s inequality and explain what the solution means.
Answer:
10 + 3x </= 30
x </= 6.666
He can make at most 6 cranes before his time runs out. He would be 2/3 through the next small one when time runs out.
Step-by-step explanation:
10 + 3x </= 30
10 is the minutes for the centerpiece
3 is the minutes to make each small crane
x is the number of small cranes he can make
he has less than or equal to 30 minutes to complete them.
10 + 3x </= 30
subtract 10 from both sides
3x </= 20
x </= 6.666
He can make at most 6 cranes before his time runs out. He would be 2/3 through the next small one when time runs out.

Brian received 45 trading cards from his mother and 25 trading cards from his uncle to start a collection.
Each week, Brian uses his allowance to buy a new pack of 15 trading cards to add to his collection.
Write an equation in slope-intercept form to represent the situation. Use x for the independent variable and y for the dependent variable. Identify what both variables represent.
Answer:
The representation of Brian's situation in slope intercept form is:
y= 15x +70
Step-by-step explanation:
Let x be the number of weeks Brian started his collection.
y be the number of cards Brian has at present.
y= 45+25+ 15 x
or, y= 15 x +70
which is in the form of,
y= mx +c (slope intercept form)
where,
m= slope
x= x- intercept
c= constant.
Find the perimeter and the area of the polygon with the given vertices.
A (12,2), B (12,13), C (15,13), D (15,2)
The perimeter is __ units.
The area is __ square units.
Answer:
Step-by-step explanation:
As points A and B have same x-coordinate, length of AB will be given by the difference of y-coordinate
AB = 13 - 2 = 11 units
As points C and D have same x-coordinate, length of CD will be given by the difference of y-coordinate
CD = 13 - 2 = 11 units
As points B and C have same y-coordinate, length of BC will be given by the difference of x-coordinate
BC = 15 - 12 = 3 units
As points A and D have same y-coordinate, length of AD will be given by the difference of x-coordinate
AD = 15- 12 = 3 units
AB = CD = 11 units
BC = AD = 3 units
So,ABCD is a rectangle
Area = 11 * 3 = 33 square units
Perimeter = 11+11+3+3 = 28 units
Answer:
Solution :-At first
Length of AB = 13 - 2 = 11 cm
Length of CD = 13 - 2 = 11 cm
Length of BC = 15 - 12 = 3 cm
Length of AD = 15 - 12 = 3 cm
Now
Perimeter = 11 + 11 + 3 + 3
Perimeter = 22 + 6
Perimeter = 28
Area = 11 × 33 = 33 cm

A community swimming pool has a deep end and a shallow end. The volume of water in the deep end can be represented by (2x2+12x+10) ft3 and the volume of the water in the shallow end can be represented by (4x2−100)ft3.
Write the equivalent expression ("simplified") that represents the total volume of the water in the pool in ft3.
Answer:
The total volume of water in the pool = ( 6x^3 + 12x^2 - 90x ) ft^3
Step-by-step explanation:
The volume of water in the deep end = (2x^3 + 12x2 + 10x) ft^3
The volume of water in the shallow = (4x^3 -100x) ft^3
The total volume of water in the pool = (2x^3 + 12x2 + 10x) + 4x^3 -100x)
= ( 6x^3 + 12x^2 - 90x ) ft^3

Using the two-way table, what percentage of the students that like to travel out of state do not like camping? Round to the nearest whole percent.
Likes Traveling Out of State Does Not Like Traveling Out of State Row totals
Likes Camping 52 38 90
Does Not Like Camping 36 74 110
Column totals 88 112 200
30%
33%
36%
41%
to find a percentage of something you take the fraction and multiply it by a hundred
Step-by-step explanation:
step one
to determine what the fraction would be you just read the question:
first you have to see what they want to calculate the percentage of. In this case it's students who like traveling out of state but don't like camping.
88 students like traveling out of state and 36 of those students don't like camping so the fraction you have to use is 36/88
step two
next you multiply your fraction by 100 to calculate your percentage
36/88 ×100= 40.9%
step three
since you have to round to the nearest whole percent your answer would be 41%
Answer:
