The result is C. 12,600. A rough estimate can be performed by calculating the room's volume and the volume of a single basketball, then dividing the former by the latter. However, this will yield an inflated estimate due to the spacing between the balls. The room volume calculates as V = L * W * H = 15 * 20 * 10 ft^3 = 3,000 ft^3. Then, the volume of one basketball is obtained from its circumference of 29 in. Using the formula for circumference, we derive the radius. Therefore, we reformulate to find the volume of a ball and divide the room’s volume by it. The final estimate is about 12,587, thus the closest answer is C. 12,600.

A direct variation function contains the points (–8, –6) and (12, 9). Which equation represents the function? y = –4/3x y = –3/4
Zina [12379]

Answer:

First, we must calculate the slope

m=Y2-Y1/X2-X1

= 9 - (-6) / 12 - (-8)

= 15/20

= 3/4

Therefore, the equation with the slope of 3/4 is Y=3/4x

To get the best deal on a microwave oven, Jeremy called six appliance stores and asked the cost of a specific model. The prices
babunello [11817]

Answer:

Step-by-step explanation:

The prices he received quotes for are as follows: $663, $273, $410, $622, $174, $374

To begin, we will find the average.

Average = total of data points/ number of data points.

Total of data points =

663 + 273 + 410 + 622 + 174 + 374

= 2516

Total count = 6

Average = 2516/6 = 419.33

Standard deviation = √summation(x - m)^2/n

summation(x - m)^2/n = (663 - 419.33)^2 + (273 - 419.33)^2 + (410 - 419.33)^2 + (622 - 419.33)^2 + (174 - 419.33)^2 + (374 - 419.33)^2

= 179417.9334/6 = 29902.9889

Standard deviation = √29902.9889

= 172.9

Question 10 Multiple Choice Worth 1 points)
lawyer [12517]

Answer:

The increase is linear since the data indicates that sunflowers grew by a consistent amount each month.

Step-by-step explanation:

Referring to the table

\begin{array}{lcccc}\text{Month}&1&2&3&4\\ \\\text{Sunflowers}&15&17.2&19.4&21.6\end{array}

Observe that the months progress incrementally (21-1, 3-2=1, 4-3=1).

Moreover

17.2-15=2.2\ [\text{from month 1 to month 2}]\\ \\19.4-17.2=2.2\ [\text{from month 2 to month 3}]\\ \\21.6-19.4=2.2\ [\text{from month 3 to month 4}]

This indicates a linear increase in sunflower count, as the data shows a consistent monthly rise.

At a small coffee shop, the distribution of the number of seconds it takes for a cashier to process an order is approximately no
Leona [12618]

Answer:

The correct answer is;

A. 0.17

Step-by-step explanation:

Here are the provided details;

The average time taken for a cashier to handle an order, μ = 276 seconds

The deviation from the average, σ = 38 seconds

The z-score for an order processing time of x = 240 seconds can be calculated as follows;

Z=\dfrac{x-\mu }{\sigma }

Thus;

Z=\dfrac{240-276 }{38 } \approx  -0.9474

The resulting probability

P(z = -0.9474) = 0.17361

Hence, the estimated proportion of orders processed in under 240 seconds is roughly 0.17361 or 0.17 when rounded to two decimal places.

A section of a tessellated plane is shown. Which type of symmetry does the tessellated plane have?
lawyer [12517]

Response:

(A)

A symmetrical outcome occurs when both figures are identical.

The half section of the illustration is tilted downward; therefore, to achieve symmetry, we must shift the figure upwards.

Then, we reflect upon the inverted image.

Thus, we achieve reflectional and translational symmetry.
