Answer:
<h2><em>
B. (b+3c)+(b+3c) </em></h2><h2><em>C. </em><em>
2(b)+2(3c)</em></h2>
Step-by-step explanation:
Given this expression 2(b+3c), its equivalent expression is derived by simply opening up the bracket as shown below;
Open the parenthesis by multiplying the constant outside the bracket with all the variables in parenthesis.
= 2(b+3c)
= 2(b)+ 2(3c)
= 2b +2*3*c
= 2b +6c
It can also be written as sum of b+3c in 2 places i.e (b+3c)+(b+3c) because multiplying the function b+3c by 2 means we are to add the function by itself in two places.
<em>Hence the equivalent expression are (b+3c)+(b+3c) and 2(b)+2(3c) or 2b+6c</em>
Answer:
6 days
210 pages
Step-by-step explanation:
As stipulated by the question, let the number of days Amir has been reading be x and the number of pages he had read to be y.
Now since he reads 35 pages per day.
Answer:
The probability distribution of X is given by,
P(X = x) 
0.17 when x = 1
0.22 when x = 2
0.28 when x = 3
0.33 when x = 4
= 0 otherwise
Step-by-step explanation:
According to the question, X is the random variable denoting age of a house to the nearest year in a neighborhood.
From the given data we can construct the following table -
Age of house(X) Frequency Relative frequency
(Almost equal to)
1 15 0.17
2 20 0.22
3 25 0.28
4 30 0.33
So, the probability distribution of X is given by,
P(X = x) 0.17 when x = 1
0.22 when x = 2
0.28 when x = 3
0.33 when x = 4
= 0 otherwise
