Dr. gavin is conducting a 2 x 4 independent-groups factorial design. how many interactions will dr. gavin need to examine?

1 answer:

8 0

For the answer to the question above, I believe the answer is simply 8.

2 groups divided into four participants. So all in all people needed is 8.
I hope this helped you. Have a nice day!

Answer:

5cm

Step-by-step explanation:

Since the pencil would only fit diagonally, the diameter would have to be half its length. The pencil is 10 centimeters long and 5 centimeters would be half of it.

What's the volume? I honestly just need the formula.

Arturiano [62]

Answer:

$v=364.5\ m^3$

Step-by-step explanation:

Volume Of A Regular Solid

When a solid has a constant cross-section, the volume can be found by multiplying the area of the base by the height. The area of a trapezium is

$\displaystyle A_t=\frac{b_1+b_2}{2}h$

where $b_1$ and $b_2$ are the lengths of the parallel sides and h the distance between them.

The figure shows a solid with a trapezoid as the constant cross-section and a height x. The volume of the solid is

$\displaystyle v=A_t\ x$

$\displaystyle v=\frac{b_1+b_2}{2}\ h\ x$

The image doesn't explicitly say if the length of 4.5 is the height of the trapezium or the length of that side. We'll assume the first, so our data is:

$\displaystyle b_1=7m,\ b_2=11m,\ h=4.5m,\ x=9m$

We now compute the volume

$\displaystyle v=\frac{7+11}{2}.(4.5)(9)=364.5$

$\boxed{\displaystyle v=364.5\ m^3}$

NemiM [27]

Answer: Median: 50, Minimum Value: 37, Maxium Value: 63, First Quartile: 44, Third Quartile: 57

Step-by-step explanation:

To find the median we have to line up the number from least to greatest. Since the number is even we have two numbers.

(37, 42, 44, 46, 47, )(49, 51,)(54, 55, 57, 61, 63)

| | |

1st Quartile 2nd Quartile 3rd Quratile

49 + 51 = 100 ÷ 2 = 50

Median = 50

The minimum value is the least number, therefore 37

The maxium number is the greatest number, therefore 63

The first quartile is the middle number in the first quartile, therefore 44

The third quartile is the middle number in the third quartile, therefore 57

I hope this helps!
