Compute the range of the box and whisker plot. Type a numerical answer in the space provided. DO not type spaces in your answer.
Answer:
94
Step-by-step explanation:
The range of a dataset is the difference between the maximum and minimum value :
The staring point of the whisker is the minimum = 4
The end point of he whisker is the maximum = 96
The range of the box and whisker plot is Hence,
Minimum = 4
Maximum = 98
Range = 98 - 4
Range = 94
Alejandro compra un terreno de 0,3 hm cuadrados y 0,9 dam al cuadrados a50 euros el metro cuadrado ¿cuanto ha pagado por el terreno?
Answer:
13.5 euros
Step-by-step explanation:
A partir de la pregunta anterior, las dimensiones del terreno se dieron como 0.3 & 0.9 m
El terreno es de forma rectangular.
Paso 1
Encontramos el área de la tierra
Área = Largo × Ancho
Área = 0.3 m × 0.9 m
Superficie = 0.27m²
Paso 2
Nos dijeron
1 m² = 50 euros
0.27m² = x
Multiplicar cruzada
x = 0.27 × 50 euros
x = 13.5 euros
Alejandro ha pagado 13.5 euros por el terreno

Which point has coordinates (-2, 3)?
Answer: I need a picture to go along with it because I see nothing.
Step-by-step explanation:
Andrew has a round trampoline with a diameter of 4 yards. What is the circumference of the trampoline?
You would use this formula for the problem...
(C=2πr) The circumference equals 2 multiplied by pi and radius.
In this problem it says diameter, but the diameter is just twice the length of the radius, so just multiply the radius by 2. Plugin your number.
C=2π(2) since 2 is half of 4, that's your radius.
Your answer is roughly C= 12.57.
You're welcome.

Changing the order of numbers and what
2 operations changes the answer?
Answer:
If you change the order of the numbers when adding or multiplying, the result is the same. Use the commutative properties to rewrite the following expressions: Use the commutative property of addition to change the order. Use the commutative property of multiplication to change the order. Use the commutative properties to rewrite the following:

Find the area explain how you got your answer
Answer:
189.27in^2
Step-by-step explanation:
Area of the rectangle is l*w
15*10= 150
Area of the circle is π r^2
We don't have radius but we have diameter so 10/2 =5
so A= π 5^2
78.53982, but we need half that since its only half a circle.
78.53982/2 = 39.26991
39.26991 + 150 = 189.26991
Write story problem that uses addition and has a solution of 6 (x=6)
Answer:
Let me give you an example of a segment addition problem that uses three points that asks the student to solve for x but has a solution x = 20.
First, I assumed values for each x, y and z and then manipulated their coefficients to get the total at the end of each equation.
20 + 10 +30 = 60
40 + 0 + 40 = 80
40 + 10 = 50
Then exchangeing these numbers into values and we have the following equation.
x + 2y + 3z = 60
2x + 4z = 80
2x + z = 50
If you will solve them manually by substituting their variables into these equations, you can get
x = 20
y = 5
z = 10

QUICKK The Johnson family went to a socially distance movie and paid $30 for two adults and two children the modern family went to the same movie and paid 35 for two adults and three children what was the price of an adult ticket
Answer: adults = $10
Step-by-step explanation:
x = adults
y = children
2x + 2y = 30
2x + 3y = 35
Using the elimination method:
2x + 2y = 30
-2x - 3y = -35 (multiplied by -1, to give 2x -2x = 0)
Solve for y...
2y = 30
-3y = -35
Add together...
-y = -5
Multiply by -1 to give positive value for y...
y = $5
Plug into one of the original equation to find x...
2x + 10 = 30
2x = 20
x = $10

A plane travels 1200 miles from San Diego, Ca to Portland, Oregon. On the way there, the plane traveled with the wind and made it in 4 hours. On the return trip, the plane traveled against the wind and made it in 6 hours. Find the speed of the plane and the speed of the wind.
Answer:
Speed of plane is 250 miles per hour and speed of wind is 50 miles per hour
Step-by-step explanation:
Let x represent the speed of the wind. When travelling with the wind, the plane travels 1200 miles within 4 hours. Hence the speed of the plane with the wind is:
speed = distance / time = 1200 miles / 4 hours = 300 miles per hour
When travelling against the wind, the plane travels 1200 miles within 6 hours. Hence the speed of the plane against the wind is:
speed = distance / time = 1200 miles / 6 hours = 200 miles per hour
Therefore:
300 - x = 200 + x
300 - 200 = x + x
2x = 100
x = 50 miles per hour
The speed of the wind = 50 miles per hour. The speed of the plane = 300 - 50 = 200 + 50 = 250 miles per hour

Find value of 'k' and solve for unknown variable
Answer:
k = 27/4
y = 283.5
Step-by-step explanation:
Let
y = amount of water used
x = number of dogs washed
y = kx
y = 81 gallons
x = 12 dogs
y = kx
81 = k * 12
81 = 12k
Divide both sides by 12
81/12 = 12k/12
k = 81/12
k = 27/4
k = 6.75
Find x when y = 42 dogs
y = kx
y = 27/4 * 42
y = (27*42) / 4
y = 1,134 / 4
y = 283.5
y = amount of water used = 283.5 gallons

Gift Wrapping A gift box has the shape of a rectangular prism. How much wrapping paper do you need to cover the box?
Answer: v= 3360
If you’re looking for the volume V=whl =14 • 16 • 15= 3360
answer:
768 in²
step-by-step explanation:
since the box is being wrapped, you'll need to use the tsa (total surface area) formula-
a=2(w*l+h*l+h*w)
= 2·(6·15+14·15+14·6)
= 768

Is the following expression a monomial, binomial, or trinomial? 2a^2 - 5a + 7
Answer: Trinomial
Step-by-step explanation: This expression has 3 terms (2a^2, -5a, and 7), so it is a trinomial. An easy way to remember this is that 'tri' = 3, 'bi' = 2, and 'mono' = 1. Hope this helped :)
£40 is divided between Jim, Krutika & Natasha so that Jim gets twice as much as Krutika, and Krutika gets three times as much as Natasha. How much does Jim get?
Answer:Jim gets £24
Step-by-step explanation:
Let the amount Natasha gets be represented as x
SO that Krutika getting three times as much as Natasha be represented as 3x
AND Jim getting twice as much as Krutika be represented as 2 x 3x=6x
The equation to show how much each gets can be represented as
x + 3x +6x=40
Solving
x +3x + 6x=40
10x =40
x =40/10 =4
Natasha gets £4
Krutika gets 3x =3x4= £12
Jim gets 6x=6 x4= £24
