Answer:
1020 students
Step-by-step explanation:
the key word is at least, this means anything under that number will not qualify. So that leaves 68 out of the 100 sample students. So if you want to have the same thing but with 1,500 students. Take off the 2 zeros at the end of 1500 and multiply by 68 getting your answer. This is because there is 2 zeros in 100, so to cancel out the 2 zeros in 100, just take out the 2 zeros in 1500 making it a lot easier.
The students in the school would be expected to do household chores for at least two hours every week with 1020 students.
We have given
Time (in hours) 0– 1 2–3 4–5 6–7
Number of Students 32 64 3 1
What is the random sample?
A simple random sample is a subset of a statistical population in which each member of the subset has an equal probability of being chosen.
The keyword is at least, this means anything under that number will not qualify.
So that leaves 68 out of the 100 sample students.

500 SQ Foot House Is The Answer.
Step-by-step explanation:
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

Help asap pls. The mean of a math test took by 50 students is 85% Two students got a 10% on the test. If those outliers were removed, what would the new mean be? Pls don't answer for points. And also DONT ANSWER TO ASK A QUESTION COMMENT IT. it takes away a chance for people who actually know the answer to answer
Answer:
okay I'm not 100% sure but I have a good idea (it's okay if u remove me it's just an educated guess)
89%
Step-by-step explanation:
if there were 100 students that would mean 1 student represented 1% of the results. so if there were 50 students 1 student would represent 2% of the results. so if two students were removed then that would mean the result would improve by a total of 4% which would get you 89%
Note: A maximum number of 4 points are available for this question. Part A is worth 1 point. Part B is worth 1 point. Part C is worth 2 points.
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.
Please help! More math sorry!
Answer:
x = 15, Angles are both 130!
Step-by-step explanation:
Since this is an example of Alternate Exterior Angles, you could set these equal to eachother!
9x-5 = 7x + 25
-7x -7x
Subtract 7x from both sides.
2x - 5 = 25
+5 +5
Add 5 to both sides.
2x = 30
Divide by two to get x by itself .
x = 15, now you can plug this in for X and get the angle
9(15) - 5 = 130
Answer:
Since this is an example of Alternate Exterior Angles, you could set these equal to each other! its 125
Step-by-step explanation:
9x-5 = 7x + 25
-7x -7x
Subtract 7x from both sides.
2x - 5 = 25
+5 +5
Add 5 to both sides.
2x = 30
Divide by two to get x by itself .
x = 15, now you can plug this in for X and get the angle
9(15) - 10 = 125

What is the solution
Please help
Answer:
Step-by-step explanation:
1.)
3x=3
x=1
2+y=0
y=-2
solution: (1,-2)
2.)
6y = -36
y = -6
-4x+12 = -12
-4x=-24
x = 6
solution: (6,-6)
Answer:
Top: x=1, y= -2
Bottom: x= 6, y= -6
Step-by-step explanation:
Top:
Isolate x for y: 2(3+y) + y = 0
Simplify: 6+3y=0
Isolate y for 6+3y=0: y = -2
For x= 3 + y: x = 1
Bottom:
Isolate x for : -4x - 2y= -12: x= [tex]\frac{-6 + y}{2}[/tex]
Simplify: 6y+ 12 = -24
Isolate y for 6y+ 12 = -24: y = -6
For x= [tex]-\frac{-6 -6 }{2} = 6[/tex] : x = 6

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.
Step-by-step explanation:
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
A spinner has 6 sectors, half of which are red and half of which are black. If the radius of the spinner is 3 inches, what is the area of the red sectors?
Answer:
b
Step-by-step explanation:
area= (radius)^2.pi:2
= 3.3.3.14:2
= 14.13 (in)^2
the area in red ishalf the area of the circle with a radius of three
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
