That answer is incorrect it is actually D. <span>The ranges for the box plots are the same, but their interquartile ranges are different. </span>

Answer:

The correct option is 4.

Step-by-step explanation:

In a box plot the left side the left corners of he box represents Q₁, the right corners of the box represents Q₃. The line inside the box represents the median of the data.

The end point of the line connecting the box from the left side is representing the minimum value of the data and end point of the line connecting the box from the right side is representing the maximum value of the data.

From the given figure we can say that for Marc's class

Minimum value = 1

Maximum value = 10

Q₁ = 3

Q₂=Median = 5

Q₃ = 9

Range = Maximum value - Minimum value = 10 - 1 = 9

Interquartile Range = Q₃ - Q₁ = 9 - 3 = 6

From Sue's class

Minimum value = 3

Maximum value = 12

Q₁ = 5

Q₂=Median = 9

Q₃ = 10

Range = Maximum value - Minimum value = 12-3 = 9

Interquartile Range = Q₃ - Q₁ = 10 - 5 = 5

Therefore the range for both box plot is same but their interquartile ranges are different. Option 4 is incorrect.

Dmitri wants to cover the top and sides of the box shown with glass tiles that are 5mm square. How many tiles does he need? ( Th

ycow [4]

Answer:

372

Step-by-step explanation:

We are given that the dimensions of the box are,

Length = 15 cm, Width = 20 cm and Height = 9 cm.

We know that the box represents a cuboid.

Since, surface area of a cuboid = L×W + 2×L×H + 2×W×H

Thus, the surface area of the box = 15×20 + 2×15×9 + 2×20×9

i.e. Surface area = 300 + 270 + 360

i.e. Surface area = 930.

Thus, the surface area of the box is 930 cm² i.e. 9300 mm².

Further, the sides of the tiles are 5 mm and the tile represents a square.

So, the surface area of the tile = 5 × 5 = 25 mm².

This gives us that,

Number of tiles required to cover the box = $\frac{9300}{25}$ = 372.

Hence, Dmitri requires 372 tiles to cover the box.

Which of the following equations is of a parabola with a vertex at (0, 6)?

RoseWind [281]

Answer:

y= x^2 + 6

Step-by-step explanation:

y= x2 + 6 (which should be written as y= x^2 + 6) has the form y - k = a(x - h)^2. For y= x^2 + 6, h = 0 and k = 6. Thus the vertex is (0, 6)

A map is laid out in the standard (x,y) coordinate plane. How long, in units, is an airplane's path on the map as the airplane f

xeze [42]

Answer:

Distance between the points A and B is 15.52 units.

Step-by-step explanation:

It has been given in the question that an airplane flies along a straight line from City A to City B.

Map has been laid out in the (x, y) coordinate plane and the coordinates of these cities are A(20, 14) and B(5, 10).

Distance between two points A'(x, y) and B'(x', y') is represented by the formula,

d = $\sqrt{(x-x')^{2}+(y-y')^{2}}$

So we plug in the values of (x, y) and (x', y') in the formula,

d = $\sqrt{(20-5)^{2}+(14-10)^{2}}$

d = $\sqrt{(15)^{2}+(4)^{2}}$

d = $\sqrt{225+16}$

d = 15.52

Therefore, distance between the points A and B is 15.52 units.
