A spinner with 5 equal section labeled 1-5 is spun 50 times. The results are shown in the table below. What is the theoretical probability of spinning an even number
Answer:
18/50
Step-by-step explanation:
The spinner was spun 50 times and both 2 and 4 are even numbers which was landed on 8 and 10 time so therefore 18/50
Answer:
i think its 2/5
Step-by-step explanation:
it says a probability of spinning an even number and there is 2 even numbers so out of the 5 there is 2 of them so it would be 2/5

2x^-2 y^-2 x= 3 and y = –2?
Answer:yes
Step-by-step explanation:
Answer:
1/18.
Step-by-step explanation:
2x^-2 y^-2
x= 3 and y = –2?
Answer is 2(3)^-2 * (-2)^-2
= 2/(3)^2 * 1/(-2)^2
= 2/9 * 1/4
= 2/36
= 1/18.

A hardware store sells 2 gallons of paint and a paintbrush for a total of $45. Last year, Katy bought 4 gallons of paint and a paintbrush in order to paint her porch and paid a total of $85. The system of equations below represents this relationship.
2x+y=45
4x+y=85
This year, Katy needs to paint a shed, so she buys more paint and paintbrushes. She replaces the equation 4x+y=85 with the equation 6x+2y=130, which is the sum of 4x+y=85 and 2x+y=45.
Determine whether each statement below is true. Select (Yes) or (No) for each statement.
The price of a paintbrush this year is $5.
The price of a gallon of paint thi year is $25.
The price of a paintbrush this year is the same as it was last year.
The price of a gallon of paint this year is the same as it was last year.
This year, Kelly buys 6 gallons of paint and 2 paintbrushes for $130.

2x-3y=7
4x-4y=4
Answer:
x=4, y=5
Step-by-step explanation:
You obtain an answer by subtracting the second equation from the first.
Step-by-step explanation:
2x-3y=7-----------(1)
multiply by 2 in first equation
4x-6y=14------------ (2)
4x-4y=4---------------(3)
then, subtracting eqn (3) from (1)
4x-6y=14
4x-4y=4
sin change - + -
_________
-2x=10
x=-5
putting value of x on eqn (3)
4x-4y=4
-20-4y=4
-4y=24
y=-6

Answer:
The average rate of change is 4.
Step-by-step explanation:
Average rate of change is simply a fancy way of saying "find the slope".
So for slope, we use (y2-y1)/(x2-x1).
(3-(-13))/(2-(-2))
16/4
4

9. Write the equation of a line that is PERPENDICULAR to 6x+3y=15 and passes
through the coordinate (12,-5).
Answer:
y = 1/2x - 11
Step-by-step explanation:
Step one convert to y = mx+b form
6x + 3y =15
Isolate Y
3y = -6x + 15
Divde the 3 among the other numbers
y = -2x + 5
That is the equation
perpindiculr to that is y = 1/2x + 5 but solve for the points and plug in
the points are (12,-5)
So -5 = 1/2 (12) +b
-5 = 6 + b
Solve for B
-5 - 6 = b
b = -11
FINAL EQUATION
y = 1/2x - 11

Answer:
[tex]p=\$1.50,\\c=\$0.75[/tex]
Step-by-step explanation:
We can write the following system of equations:
[tex]\begin{cases}3p+2c=6.00,\\2p+3c=5.25\\\end{cases}[/tex]
Multiply the second equation by [tex]-\frac{3}{2}[/tex] to isolate and solve for [tex]c[/tex]:
[tex]\begin{cases}3p+2c=6.00,\\-3p-4.5c=-7.875\\\end{cases},\\-2.5c=-1.875,\\c=\fbox{$\$0.75$}[/tex],
Now plug in [tex]c=0.75[/tex] into any equation to solve for [tex]p[/tex]:
[tex]3p+2(0.75)=6.00,\\3p=4.50,\\p=\fbox{$\$1.50$}[/tex].
Answer:
One Slice of Pizza is $1.50
One cola is $0.75
Step-by-step explanation:
First, we need to define our variables:
x = pizza
y = cola
Next, we need to create two equations (one for Tanisha's order and one for Rachels order) using the information provided in the problem:
3x + 2y = 6.00
2x + 3y = 5.25
Now, we need to use one of the equations to solve for one of the variables:
3x + 2y = 6.00
2y = 6 - 3x
y = 3 - 1.5x
Next, we need to substitute y into one of the equations to find x:
2x + 3 (3 - 1.5x) = 5.25
2x + 9 - 4.5x = 5.25
-2.5x + 9 = 5.25
-2.5x = -3.75
x (or price per slice of pizza) = 1.50
Finally, we need to use the value we found for x to solve for y:
(2 x 1.5) + 3y = 5.25
3 + 3y = 5.25
3y = 2.25
y (or price per cola) = .75
I hope this helps!

how do you Round 96,286 to the nearest thousand.
Answer:
The correct answer is 96,000
Step-by-step explanation:
To round you look at the thousands place and there is a 9 then you look at the number to the right of it which is 2 and it is lower than 5 since it is lower than five it rounds down so the correct answer is 96,000.
HAVE A GOOD DAY!
Answer:
96,000
Step-by-step explanation:
If the number on the right of the nearest thousand is lower than 5 the nearest thousand and the numbers to the left of it stay the same, while the numbers on the right turn into 0(zeros) but if the number in the right of the nearest thousand is 5 or grater then the nearest thousand would go up one digit while the numbers on the left of the nearest thousand stay the same, while the numbers on the right of the nearest thousand turn to zeros.

12. UZ, VX, and TW are medians of Triangle TUV. If YX = 8, find VY.
Answer:
VY = 16
Step-by-step explanation:
The median of a triangle is the segment that joins a vertex and the midpoint of the side opposite to this vertex.The point of intersection of the medians of a triangle, divide each median at ratio 2: 1 from the vertex.In the given figure
∵ TUV is a triangle
∵ UZ, VX, and TW are medians
∵ UZ ∩ VX ∩ TW at point Y
∴ Y is the point of intersection of the 3 medians
→ By using the 2nd rule above
∵ The point Y divide VX at the ratio of 2: 1 from the vertex V
∴ VY: YX = 2: 1
∴ [tex]\frac{VY}{YX}[/tex] = [tex]\frac{2}{1}[/tex]
→ By using cross multiplication
∵ VY × 1 = YX × 2
∴ VY = 2YX
∵ YX = 8
∴ VY = 2(8)
∴ VY = 16

1100 students attend Ridgewood Junior High School. 20% of students bring their lunch to school everyday. How many students brought their lunch to school on Thursday?
Answer:
20% of 1100 is 220, so two hundred and twenty students brought their lunch to school on Thursday (and every other school day).
Step-by-step explanation:
The day of the week is a distraction. All you need to know is that 20% of 1100 students bring their lunch to school every day. 20% of 1100 is 200 + 20, or 220. So 220 students bring their lunch to school every day.
