Range: the maximum is 11 and the minimum is 3. Range is the max minus the min, so 11-3=8.

Answer:

The correct answer is Range.

Step-by-step explanation:

For box-and-whisker plot, the range is illustrated by the distance between the opposite ends of the whiskers, you ignoring the outliers.

In this case, the whisker starts at 3 and ends at 11.

Range = 11-3 = 8.

Write an equation of the line in slope-intercept form. JY 1 (3, 3) (0, 2) 2 4 y=

stellarik [79]

Correct answer: y = $\frac{1}{3}$ x + 2

To find out the slope, you would need to remember this slope formula: $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$ . We can use the two points provided on the graph to figure out the slope. We can label (3, 3) as $x_{1}$ and $y_{1}$ , and (0, 2) as $x_{2}$ and $y_{2}$ . Now we can plug these numbers into the slope formula to find out the slope:

m = $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$ → $\frac{2-3}{0-3}$ → $\frac{-1}{-3}$ → $\frac{1}{3}$

To find out the y-intercept, just substitute (3, 3) into the slope-intercept formula ( y = mx + b ) with the slope that is substituted for 'm' that we already solved earlier.

y = mx + b

(3) = $\frac{1}{3}$ (3) + b

3 = 1 + b

2 = b

You can also prove this true by looking at the graph provided. The line intersects at the y-axis at 2.

Now we know that m = $\frac{1}{3}$ and b = 2, we can substitute it into the slope-intercept formula. Thus, the answer is y = $\frac{1}{3}$ x + 2.

Hope this helps you! Let me know if you have any more questions related to this problem.

On the weekend for every 2 minutes you spend watching puppy videos you spend 9 minutes watching regular tv. If you spend 572 min

harkovskaia [24]

Answer:

104 mins, 468 mins

Step-by-step explanation:

Let the time spent on puppy videos = 2x

Where x is the number of weekends.

Time spent on regular TV = 9x.

So total time spent is 572 mins

i.e 2x + 9x = 572

i.e 11x = 572

So x = 52.

So time spent on puppy videos = 2 X 52

= 104 mins

So time spent on puppy videos = 9 X 52

= 468 mins.

The volume of a cylinder is given by the formula v= m'h. where r is the radius of the cylinder and h is the height.

Verdich [7]

Answer:

The Volume of cylinder is: $\mathbf{Volume=2\pi x^3-5\pi x^2-24\pi x+63\pi }$

Option B is correct option.

Step-by-step explanation:

We are given:

Volume of cylinder = h = 2x+7

Radius of cylinder = r = x-3

We need to find volume of cylinder

The formula used is: $Volume=\pi r^2h$

Putting values and finding volume

$Volume=\pi r^2h\\Volume=\pi (x-3)^2(2x+7)\\Volume=\pi (x^2-6x+9)(2x+7)\\Volume=\pi (2x(x^2-6x+9)+7(x^2-6x+9))\\Volume=\pi (2x^3-12x^2+18x+7x^2-42x+63)\\Volume=\pi (2x^3-12x^2+7x^2-42x+18x+63)\\Volume=\pi (2x^3-5x^2-24x+63)\\Volume=2\pi x^3-5\pi x^2-24\pi x+63\pi \\$

So, The Volume of cylinder is: $\mathbf{Volume=2\pi x^3-5\pi x^2-24\pi x+63\pi }$

Option B is correct option.
