Answer:

(0,-5)

Step-by-step explanation:

By the Graph Method, for single solution the solution will be the intersection point of these lines. Each line is defined by an equation. The first one: x+y=-5 and the Second one: -3x-y=5

So, (0,-5) is the solution.

A student studying his classmates' cars' ages reports the 5-number summary as {1, 3, 4, 8, 20}. what is the iqr for his data?
timurjin [86]

IQR for the data {1, 3, 4, 8, 20} is 5.

Interquartile Range(IQR) for a data is defined as the difference between third quartile and first quartile.

denoted by  IQR=Q₃-Q₁              (Q₃ is third quartile and Q₁ is first quartile)

The five number summary of a data set is represented as

{minimum, first quartile , second quartile , third quartile , maximum}..…(1)

According to the question

{1, 3, 4, 8, 20}

On comparing it with equation   …(1)

minimum=1

Q₁ =3    , Q₂=4 , Q₃=8 , maximum =20

IQR=Q₃-Q₁

Substituting the values we get

IQR=8-3=5.

Therefore , Interquartile Range for the data {1, 3, 4, 8, 20} is 5.

What’s the answer???
azamat

Answer:

C = 6.28 in.

A = 3.14 in.^2

Step-by-step explanation:

C = (pi)d

C = 3.14 * 2 in.

C = 6.28 in.

A = (pi)r^2

r = d/2 = 2 in./2 = 1 in.

A = 3.14 * (1 in.^2)

A = 3.14 in.^2
