Each month, a retail store awards a blue ribbon to its employee of the month. the probability that chloe is the employee of the month is 29% in january and 49% in february. what is the probability that she is awarded a blue ribbon in both january and february? 14.21% 19.51% 10.00% 21.81%

Option A. 14.21%

Step-by-step explanation:

The probability that Chloe is awarded the employee of the month in January  

= 29%  P (J) = 0.29

The probability that Chloe is awarded the employee of the month in February = 49% P (F) = 0.49

As we know that both events are independent so

P ( J & F ) = P (J) × P (F)

P = 0.29 × 0.49 = 0.1421 or 14.21%

Therefore the probability that she is awarded a blue ribbon in both January and February 14.21%

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
