Answer:

Pr = 0.153

Step-by-step explanation:

Given

p = 15.3\%

Required

Probability of alarm not working

p = 15.3\% implies that the alarm has a probability of not working on a given day.

So, the probability that the alarm will not work on an exam date is:

Pr = 15.3\%

Express as decimal

Pr = 0.153

An ice cream cone with a diameter of 2 inches and a height of 3.5 inches is filled with ice cream and more ice cream on top in t
fomenos

Answer:

11pi/6 in^3 or

5.760 in^3 to the nearest thousandth.

Step-by-step explanation:

Volume of ice cream = volume of the cone + volume of the hemisphere

= 1/3 pi r^2 h + 1/2 * 4/3 pi r^3    

= 1/3 pi 1^2 * 3.5 + 2/3 pi 1^3             (as the radius = 1/2 * diameter)

=  (7/6 + 2/3) pi

= 11pi/6 in^3.

Which graph shows a proportional relationship?<br> A. B. C D.
bonufazy [111]

Answer:

B

Step-by-step explanation:

a proportional relationship must have a straight line when graphed and it must go through the origin (0,0)

Right off the bat we can eliminate answer choice C because the line is not straight

the answer is not a nor d

the line may be straight but it does not go through the origin therefore it is not a proportional relationship

B makes a straight line and the line goes through the origin therefore B is the answer
