Answer:

(Head and D) = 1/10

(Tails and A or D) = 1/5

Step-by-step explanation:

A coin has two sides so that a 50% chance that it will land on heads or tails

A pentagonal spinner has a 40% chance that it will land on D or A.

P (Heads) = 1/2

P (D)= 1/5

1/2 · 1/5 = 1/10

P (Heads and D) = 1/10

____________________________________________________________

P (Tails) = 1/2

P(A or D) = 2/5

1/2 · 2/5 = 1/5

P (Tails and A or D) = 1/5

How do you find the average velocity over an interval?
Artist 52 [7]

If the moving object is undergoing constant acceleration, then

v_{\rm avg}=\dfrac{v_i+v_f}2

(take the average of the initial and final velocities, if they're given)

If you don't know the acceleration or initial/final velocities, then you have to resort to the usual definition,

v_{\rm avg}=\dfrac{\Delta x}{\Delta t}

where \Delta x is the change in position and \Delta t is the duration of the interval.

The range for the Kentucky temperatures is . The range for the Illinois temperatures is . The IQR for the Kentucky temperatures
natima [27]

The boxplot required to answer the questions is attached below :

Answer:

The range for the Kentucky temperature :

(58.3 - 52.2) = 6.1

The range for the Illinois temperature :

(55 - 49.9) = 5.1

The IQR for the Kentucky temperature :

(57.3 - 54.5) = 2.8

The IQR for the Illinois temperature :

(53.3 - 50.9) = 2.4

Step-by-step explanation:

Range = maximum - minimum

Maximum and minimum values are given by the values at the end and start of the whisker.

The range for the Kentucky temperature :

(58.3 - 52.2) = 6.1

The range for the Illinois temperature :

(55 - 49.9) = 5.1

IQR = Q3 - Q1

Q3 = Value at the end of the box

Q1 = value of start of box

The IQR for the Kentucky temperature :

(57.3 - 54.5) = 2.8

The IQR for the Illinois temperature :

(53.3 - 50.9) = 2.4
