Answer
Step-by-step explanation:
first order them from least to greatest
then keep eliminating one till u get one in the middle thats the median
to find mean u have to find advarge so u take highest and divide by lowest
Answer:
Mean: 522.16
Median: 427.3
Step-by-step explanation:
mean is the average and median is the middle value when you place them from the smallest to greatest
The numbers are 279.18, 271.11, 309.80, 363.45, 409.79, 444.81, 603.53, 695.46, 872.03, 972.42
If we add them all up then it would be 5221.58, then we need to divide it by 10 because there are 10 different sets of number
5221.58÷10=522.158 If we round it up it would be $522.16
Next, we need to put all the number in the order of smallest to biggest
271.11, 279.18, 309.90, 363.45, 409.79, 444.81, 603.53, 695.46, 872.03, 972.42
The number in between are 409.79 and 444.81
We need to find the average of these 2 number
(409.79+444.81)÷2=854.6÷2=427.3
molly’s hair was 20 inches long three years later it was 35 years long what was the percent increase to the nearest hundredth
Answer: 75%
Step-by-step explanation:
PLEASE DON'T SKIP MY QUESTION!!!! SUPER IMPORTANT I AM SO LOST AND CONFUSED At a movie theater, the price of 2 adult tickets and 4 child tickets is $48. The price of 5 adult tickets and 2 child tickets is $64. Let x be the cost of an adult ticket and let y be the cost of a child ticket. Write and solve a system of equations to find the ticket price for one adult and for one child.
The answer is $10 per adult ticket, and $7 per child ticket. Now lets figure out how to get to that answer. Let's create a chart to help visualize this.
- - - - -A- - - - - C- - - - -T- - - - -
: 2 : 4 : $48 :
: 5 : 2 : $64 : Key:
: : : : A = Adult ( The Y)
: : : : C = Child ( The X)
: : : : T= Total
When we look at it, the total cost is less then what the adult would be when multiplied by 10, and you WOULD have to add the children cost to the adult cost, so lets try it.
Lets do the 2 adult tickets first, 2 x 10 is 20. Now we do 48 - 20 to get how much the cost of the children's 4 needs to equal. We get 28 as the answer. Now we have to do 28 divided by 4, we get 7 as that answer.
Now lets plug that in to the $64 problem and see if that gets us the correct answer.
So the amount of adult tickets for this problem is 5, so we do 5 x 1 which is 50.
Now the amount of children tickets is 2, so lets do 2 x 7, which equals 14.
Now to test if it gets us the correct answer, to do that we do 50 + 14, that equals what we want it to, 64.
Therefor, the correct answer is $10 per adult ticket, and $7 per child ticket.
Hope this helps!
If you know the answer to this, pls let me know! Thanks!!!! :))))
Answer:
x= 30
Step-by-step explanation:
3x + 50 = 140
3x = 140 -50
3x = 90
x = 90/3
x = 30
Answer:
x = 30
Step-by-step explanation:
The given angles are vertical and congruent , then
3x + 50 = 140 ( subtract 50 from both sides )
3x = 90 ( divide both sides by 3 )
x = 30

Find the slope of the line that passes through (8,4) and (6,5)
Answer:
-1/2
Step-by-step explanation:
The equation for slope is y2 - y1 and x2 - x1. So you do 5(y2) - 4 (y1) which is 1. And 6(x2) - 8(x1) which is -2. Put 1 as the numerator and -2 as the denominator as you got -1/2. The fraction is negative because the -2 made it that way

A square parking lot has an area of 12,996 square yards. a. What is the length of one side of the parking lot? b. How many yards of fence will it take to enclose the entire parking lot?
Answer:
114 yards
456 yards
Step-by-step explanation:
Given that:
Area of square parking lot = 12,996 square yards
The lenght of one side of the parking lot :
Area of a square = a² ; a = side length
Hence ;
12996 = a²
√12996 = a
114 = a
Hence, length of one side = 114 yards
Yards of fence needed to enclose parking lot :
Perimeter of a square = 4a ; a = side length
Perimeter = 4(114)
Perimeter = 456 yards

Can someone explain this to me?
Answer:
Step-by-step explanation:
a). By applying tangent rule in the triangle,
tanθ = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}=\frac{3}{4}[/tex]
θ = [tex]\text{tan}^{-1}(\frac{3}{4})[/tex]
θ = 36.87°
Therefore, θ < 45°
b). By using cosine rule in this triangle,
cosθ = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}=\frac{18}{18\sqrt{2}}[/tex]
cosθ = [tex]\frac{1}{\sqrt{2}}[/tex]
θ = 45°
c). By using tangent rule,
tanθ = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}=\frac{8}{2}[/tex]
θ = [tex]\text{tan}^{-1}(4)[/tex]
θ = 75.96°
θ > 45°

. Find four consecutive odd integers such that the sum of the first and fourth is 55 greater than the opposite of the third.
Answer:
The four consecutive odd integers = 15, 17, 19, 21
Step-by-step explanation:
Four consecutive odd integers in Mathematics when x is an integer is given as:
x , x + 2 , x + 4, x + 6
Where:.
First integer = x
Second integer = x + 2
Third integer = x + 4
Fourth integer = x + 6
The sum of the first and fourth is 55 greater than the opposite of the third
Hence :
x + x + 6 = -(x + 4) + 55
x + x+6 = (-x - 4) + 55
2x + 6 = -x + 51
Collect like terms
2x + x = 51 - 6
3x = 45
x = 15
Therefore,
First integer = x = 15
Second integer = x + 2 = 15 + 2 = 17
Third integer = x + 4 = 15 + 4 = 19
Fourth integer = x + 6 = 15 + 6 = 21
The four consecutive odd integers = 15, 17, 19, 21
