Answer: It would take 9 hours to 3 people to plough the field

Step-by-step explanation:

Hi, first we have to calculate how much time spends 1 person to plough the field.

We have to divide the number of hours spent by the number of people.

2 /6 = 3 hours per people

So, we have the rate. Now we simply multiply it by 3 to answer the question.

3 x3 = 9 hours

It would take 9 hours to 3 people to plough the field

How would you find the vertices of an image of a figure was rotated 270 degrees clockwise? 15 POINTS! DESPERATE

Rotation Coordinate Notation About the Origin:

90–degree counterclockwise: (x, y) → (-y, x)

180–degree counterclockwise: (x, y) → (-x, -y)

270–degree counterclockwise: (x, y) → (y, -x)

Use this to help you..

Example -

The vertices of a triangle are

( 1 , 3 ) ( 3 , -4 ) , ( - 6 , -8 )

270 degrees , clockwise , rotated from origin ( x , y ) - ( y , -x )

The first vertice = ( 1 , 3 )

after rotation - ( 3 , - 1 )

The second vertice = ( 3 , -4 )

After rotation - ( -4 , -3 )

The third vertice = ( -6 , - 8 )

After rotation - ( -8 , 6 )

Hope my answer helps!

Both sets of values have an average of 13. Is Set A's standard deviation smaller, larger, or about the same as Set B's? (Note: T

polet [3.4K]

Hi there!

<u>Set A has a LARGER standard deviation. </u>

A set's standard deviation is equivalent to:

$\sigma = \frac{\sqrt{\Sigma (x - \mu)^2 }}{n-1}$

σ = standard deviation

x = value

μ = mean

n = # of observations

Basically, standard deviation is calculated using how far apart EACH value is from the set's mean. If more values are FARTHER away from the mean, the standard deviation increases and vice-versa.

Set A has a GREATER RANGE and its values are farther from 13 on both sides compared to Set B which has a SMALLER RANGE and its values are closer to 13.

Therefore, Set A will have a larger standard deviation.
