Answer:

Choice D

Step-by-step explanation:

The distance increases at a steady rate from time = 0 to time = 1.

Then no progress is made between time = 1 and time = 2.

Then the distance increases at the same steady rate from time =2 to time = 3.

Finally, no progress is made between time = 3 and the end of the graph.

Eliminate Choices A, B and C immediately, because none of these scenarios involves a stop and wait.

That leaves only Choice D as a reasonable verbal description of what's happening here.

Answer:

Outliers are often extreme values that are not as representative of the data set as the other points in the cluster. If the outliers are included, a description of the data set might be misrepresented.

An open box with a square base is to be made from a square piece of cardboard 24 inches on a side by cutting out a square from e

laila [671]

Answer:

x=4 Inch

Step-by-step explanation:

Length of the Square = 24 Inches

If a Square of Length x cm is cut out from each corner

Length of the Box = 24-x-x=(24-2x) Inches

Width of the Box =24-x-x=(24-2x) Inches

Height of the box = x inches

Volume of a Cuboid = Length X Width X Height

V(x)= x(24-2x)(24-2x)

Simplifying

V(x)=4x(12-x)(12-x)

To determine the value of x at which V is largest, we take the derivative of V(x) and solve for the critical points.

V(x)=4x(12-x)(12-x)

$V^{'}(x)=12(x-12)(x-4)$

Set the derivative equal to zero to obtain the critical points

$V^{'}(x)=12(x-12)(x-4)=0\\Since \: 12\neq 0\\(x-12)(x-4)=0\\x-12=0 \:or\: x-4=0\\x=12 \:or\: x=4$

x cannot be equal to 12 as it divides the length of the square cardboard into exactly two equal parts.

When x=4

V(4)=4*4(12-4)(12-4)=16*8*8=1024 Cubic Inches

When x=4 Inch, the volume, V of the open box is largest.

Solve for x. -3.5x = -35

r-ruslan [8.4K]

Answer:

$- 3.5x = - 35 \\ x = \frac{ - 35}{ - 3.5}( - \div - = + ) = \frac{35}{35 \times .1} \\ = \frac{1}{.1} = 10 \\ x = 10 \\ thank \: you$
