Answer:
A can paint in 3days and B in 6 days
Step-by-step explanation:
From the question we were told
Person A can paint the neighbors house 2 times as fast as Person B
Let A only paint the neighbors house in X days
Let B only paint the neighbors house in 2X days
If we express the given information from the question in terms of fraction we have,
1/X + 1/2X = 1/2
3/2X = 1/2
if we cross multiply we have
6= 2X
X= 6/2
X= 3
Then A can paint the house in 3 days and B in 2(3)= 6days.
Answer:



Step-by-step explanation:
In this case we can calculate the probability using the binomial probability formula

Where p is the probability of obtaining a "favorable outcome " x is the number of desired "favorable outcome " and n is the number of times the experiment is repeated. In this case n = 10 and p = 0.54.
(a) exactly five
This is:

So:


(b) at least six
This is: 


(c) less than four
This is: 


To find three equivalent fractions of a fraction, simply multiply the fraction by a common factor.
For example, multiple both the numerator and denominator of 9/7 by 2.
This will give you a fraction of 18/14, which is equivalent.
You can do this with any number you like to create three equivalent fractions.
Answer:
the first selection is so shaded
Step-by-step explanation:
Each strip is divided into 10 parts. 1/5 will be represented by 2 of those parts, so 2/5 will be represented by 4 of the 10 parts. The 3/10 used on the other gift will be represented by 3 additional parts. So, a total of 7 of the 10 parts of the strip need to be colored to represent the ribbon used.
