Answer:
2012.87
Step-by-step explanation:
Increased amount = 17% of 2024 = 0.17 * 2024 = 344.08
Amount after increment = 2024 + 344.08 = 2368.08
Decreased amount = 15% of 2368.08
= 0.15 * 2368.08
= 355.212 = 355.21
Final amount = 2368.08 - 355.21 = 2012.87
1 meter = 100 centimeters
Therefore 4.6 metres = 4.6 * 100
= 460 centimeters (answer)
Part (a)
P(A) = 0.5
P(B) = 0.4
P(B/A) = 0.6
P(A and B) = P(A)*P(B/A)
P(A and B) = 0.5*0.6
P(A and B) = 0.3
<h3>Answer: 0.3</h3>
==========================================
Part (b)
We'll use the result from part (a)
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = 0.5 + 0.4 - 0.3
P(A or B) = 0.6
<h3>Answer: 0.6</h3>
===========================================
Part (c)
A and B are not independent since P(B) does not equal P(B/A). The fact that event A happens changes the probability P(B). Recall that P(B/A) means "probability P(B) based on event A already happened". A and B are independent if P(B) = P(B/A).
Events A and B are not mutually exclusive since P(A or B) is not zero.
<h3>Answer: Neither</h3>
Let us say that the number of weeks is "x" and the number of chores is "y".
If we state an algebraic expression for Janie's allowance it would be
3x+2y=13
However, there are two variables, hence many answers. To solve this problem, there must be more information about the relation between x and y.
3.5, it is the coefficient and describes how many n there are
