Im not sure if you wrote this wrong because (x+y)2 does equal x2+y2. An example would be if x equals 3 and y equals 4 (3+4)2=(3)2+(4)2 (7)2=6+8 14=14.
648 is the three-digit positive integers have three different digits
According to the statement
we have given that there are three positive digit number are formed with three distinct digits.
And we have to find that the how many words are formed with distinct numbers.
So, to solve this type of problem the Combination formula is best.
Because it provides the all possibilities that from how many ways numbers are formed.
So, from a combination formula
here we take 9 two times because first time when we let a number then remaining numbers are 9. and second time remaining numbers are also 9 because we let the distinct number but for third number there will be a probability that choosing number will be same.
So, Three digit positive number become from 9*9*8 =648
So, 648 is the three-digit positive integers have three different digits.

Answer:
To create a histogram of the given data set, we first must check for the frequency of each value.
6, 3, 8, 8, 6, 6, 8, 2, 5, 2, 5, 10, 3, 5
2 - 2
3 - 2
5 - 3
6 - 3
8 - 3
10 - 1
Now that we have the frequencies of each, we need to add them to each range.
0 - 2 : 2
3 - 5 : 5
6 - 8 : 6
9 - 11 : 1
Refer to the image for the histogram.
Answer:
y = - 0.9167 - 0.75x
Step-by-step explanation:
Given the data:
(−1, 0), (1, −2), (3, −3)
X : - 1, 1, 3
Y : 0, - 2, - 3
The regression model is written in the form:
y = C + mx
Where ;
C = intercept ; m = slope / gradient
Using the regression model calculator on the data values given above :
Slope (m) = - 0.75
Intercept (c) = - 0.9167
Hence,
y = - 0.9167 - 0.75x
c
