T us assume the two numbers to be "x" and "y".
Then
2x + y = 310
And
x - y = 55
Let us take the second equation and find the value of x in relation to y.
x - y = 55
x = y + 55
Now let us put the value of x in the first equation, we get
2x + y = 310
2(y + 55) + y = 310
2y + 110 + y = 310
3y = 310 - 110
3y = 200
y = 200/3
= 66 2/3
Now putting the value of y in the second equation, we get
x - y = 55
x - (200/3) = 55
3x - 200 = 55 * 3
3x = 165 + 200
x = 365/3
= 121 2/3
So the value of x is 121 2/3 and the value of y is 66 2/3
we are given
point-A= -7
point-B=8
(a)
opposite of point-A is negative of point-A value
so,
opposite of point-A is -(-7)
opposite of point-A is 7
opposite of point-B is negative of point-B value
so,
opposite of point-B is -8
opposite of point-B is -8
(b)
we can see that
opposite of point-A is 7
opposite of point-B is -8
they are not equal
so, this argument is FALSE.......Answer
Answer: 0.355,0.405)
Step-by-step explanation:
Given : Significance level :
Number of subjects (n) = 2455
Number of surveys returned = 931
The probability of surveys get return will be :-
The confidence interval for proportion is given by :-
Hence, the 99% confidence interval for the proportion of returned surveys : (0.355,0.405)
