What does the a small MAD tell you about a set of data

Tamiku [17]

Answer:

Mean absolute deviation is the average of the absolute deviations from the mean. It is a measure of variability, which gives us an idea about the spread of data points from mean. Therefore, the small MAD means the data points are less deviated from mean. And the large MAD means the data points are more deviated from mean.

Hence, smaller the MAD lesser the variation in data.

If it took Carlos 30 minutes to cycle from his house to the library yesterday, was the distance that he cycled greater than 6 mi

Ivanshal [37]

Answer:

1) No

2) Yes

Step-by-step explanation:

Given : If it took Carlos 30 minutes to cycle from his house to the library yesterday.

To find : Was the distance that he cycled greater than 6 miles?

Solution :

The relation between speed , distance and time is

$\text{Distance}=\text{Speed}\times \text{Time}$

1) The average speed at which Carlos cycled from his house to the library yesterday was greater than 16 feet per second.

Speed = 16 feet per second

Converting into miles, $s=\frac{16}{5280}$

Time = 30 minute

Converting into seconds, $t=30\times 60$

The distance he covered is

$\text{Distance}=\frac{16}{5280}\times30\times 60$

$\text{Distance}=5.45\text{ miles}$

No, the distance that he cycled is not greater than 6 miles.

2) The average speed at which Carlos cycled from his house to the library yesterday was less than 18 feet per second.

Speed = 18 feet per second

Converting into miles, $s=\frac{18}{5280}$

Time = 30 minute

Converting into seconds, $t=30\times 60$

The distance he covered is

$\text{Distance}=\frac{18}{5280}\times30\times 60$

$\text{Distance}=6.13\text{ miles}$

Yes, the distance that he cycled is greater than 6 miles.

A. Using a protractor, draw a triangle that has two angles of 40°. Label all angle measures on your drawing and include your dra

PtichkaEL [24]

Answer:

Step-by-step explanation:

By terms of angle based conclusion triangle can be Obtuse angled triangle and by considering the sides as all angles are different It will be Scalene Triangle.

Step-by-step explanation:

Given:

Two angles of 40 degree

To Find :

How many triangles are possible Construct the triangle with given condition and Describe it.

Solution:

For Construction ,

Consider Triangle ABC with

∠A+∠B=40

So for 1st possibility as ∠A=10 then ∠B=30

2nd possibility as ∠A=20 then ∠B=20

3rd Possibility as ∠A=30 then ∠B =10

And angle c will remain the same for all three possibility i.e

Sum of all angles in triangle is 180

so angle c=140 degrees.

Hence there 3 Possibilities by which triangles can be made

So both angle A and B are acute angle since they measure less than 90 degree.

And angle C is Obtuse angle always

So angles in triangles are 2 acute and one Obtuse angle.

So One angle is Obtuse then triangle is Obtuse angled triangle

So triangle ABC is Obtuse angled triangle.

we can say that all three side will be different as all angles are different measures

So Triangle ABC is scalene triangle.

hope this helps =)
