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

Answer:
The image coordinates are D'(8, 5), E'(12, 3) and F'(10,0)
Step-by-step explanation:
Given the vertices of △ DEF are D (2, 5), E (6, 3), and F (4, 0). We have to translate the triangle using the vector (6, 0)
Now, translation by vector (6, 0)
D (2, 5)=D'(2+6, 5+0)=D'(8, 5)
E (6, 3)=E'(6+6, 3+0)=E'(12, 3)
F (4, 0)=F'(4+6, 0+0)=F'(10,0)
Now, we have to label the coordinate of the triangle or to get image of triangle after translation.
Hence, The image coordinates are D'(8, 5), E'(12, 3) and F'(10,0)
Answer:
<u>12.5% ≈ 13%</u>
Step-by-step explanation:
The rest of the question is: There are 75 pills in the batch.
The current batch of pills is the first of the day and our goal is to produce a total of 600.
If there are 75 pills in the batch so percentage of goal completed will be
[(number of pills in the batch)/(Total pills)] * 100
≈ 13% to the nearest whole number
