Answer:
None of the options are correct.
Step-by-step explanation:
Let the complex number is a + ib
Given distance from origin = 17 units
Now, by distance formula distance of a point from the origin =
1) <u>Check for 2 + 15 i</u>
here, 
≠ 17
2)<u> Check for 17 + i</u>
here, 
≠ 17
3)<u> Check for 20 - 3 i</u>
here, 
≠ 17
4) <u>Check for 4 - i</u>
here, 
≠ 17
Hence, none of the options are correct.
Answer:
The Correct Answer are
- The ordered pair (2, 3) is not a solution to the system of linear equations.
- When (2, 3) is substituted into the first equation, the equation is true.
- When (2, 3) is substituted into the second equation, the equation is false.
Step-by-step explanation:
The Correct Answer are
- When (2, 3) is substituted into the first equation, the equation is true.
3x + 4y = 18 equation ( 1 )
3×2 + 4×3 = 18
6 + 12 = 18
18 = 18
- When (2, 3) is substituted into the second equation, the equation is false.
2x – 2y = 2
2×2 - 2×3= 4 - 6 = -2≠2
- The ordered pair (2, 3) is not a solution to the system of linear equations.
Solution means if we (2, 3) Substitute in both the Equation it Must Satisfy
But in Equation 1 it Satisfy
and in Equation 2 Not satisfy
Therefore It is NOT a solution to the system.

1 mile=1.609 kilometers
Answer:
The standard error of the mean is 0.85.
Step-by-step explanation:
The given standard deviation of a population (σ) = 7.8
sample size (N) = 85
We have to find standard error of the mean.
The formula to find standard error of the mean
= (standard deviation of the distribution) / (square root of sample size)
= (σ) / (√N)
= 7.8 / (√85)
= 7.8 / 9.219544457
= 0.8460
= 0.85 (approximately taken to two decimal places)
We have got the required answer.
The standard error of the mean is 0.85.
There's an equation to find the length between 2 points on a plane.
√[(2-4)2 + (2-7)2] = √29
√[(4-6)2 + (7-2)2] = √29
√[(2-6)2 + (2-2)2] = 4
Therefore, Triangle ABC is an iscoceles triangle!
