Answer:
The midpoint is (3/2,0)
Step-by-step explanation:
To find the x coordinate of the midpoint, add the x coordinate of the endpoints and divide by 2
(7+-4)/2 = 3/2
To find the y coordinate of the midpoint, add the y coordinate of the endpoints and divide by 2
(-2+2)/2 = 0
The midpoint is (3/2,0)
Answer:
1/7 ;
0.0034
Step-by-step explanation:
Given that:
X = 1/14, 1/7, 3/14
n = number of observations = 3
Since, probability of X is equally likely ;
P(X) = Σp(x) = 1 ; p(x) = 1/n = 1/3
The mean, m ;
Σx*p(x) = (1/3 * 1/14) + (1/3 * 1/7) + (1/3 * 3/14)
= 1/42 + 1/21 + 3/42
= (1 + 2 + 3) / 42
= 6 / 42
= 1/7
The variance :
Σx²*p(x) - m²
((1/3) * (1/14)^2) + ((1/3) * (1/7)^2) + ((1/3) * (3/14)^2) - (1/7)^2
= 0.0238095 - 0.0204081
= 0.0034014
= 0.0034
The value of the unknown variable x by virtue of the geometric sequence given in the task content is; -27.
<h3>What is a geometric sequence and what is the value of x in the sequence given?</h3>
It follows from the task content above that the variable given above is a member of the geometric sequence.
Hence, since it follows from convention that the geometric sequence in discuss has same common difference across each successive term and hence , we have;
3/x = (-1/3) ÷ 3
x = -27.
Therefore, the value of the unknown variable x by virtue of the geometric sequence given in the task content is; -27.

Answer:
- 4
Step-by-step explanation:
Step 1:
- 2 ( 3x - 4 ) - x - 3 = 33
Step 2:
- 6x + 8 - x - 3 = 33
Step 3:
- 7x + 5 = 33
Step 4:
- 7x = 28
Step 5:
- 28 = 7x
Answer:
- 4 = x
