4x +5y = -20
for an equation in standard form, you can write the equation for the perpendicular line by swapping the x- and y-coefficients and negating one of them. you need the x-coefficient to be positive, so it is needed to negate that one here. This gives you the equation ...
4x +5y = (some constant)
You find the value of the constant by evaluating the expression at the given point:
4x +5y = 4(5) +5(-8) = -20
The equation is 4x +5y = -20

Answer:
20 measured and 10 used
Step-by-step explanation:
Total number of participants is given as n = 10.
Number of treatment conditions = 2
Total measurements is therefore 2 × 10 = 20
Therefore, in total, 20 scores will be measured in the given study.
Now there are two samples and for each sample, for each sample we need to calculate the mean = Sum of value(measures)/Number of measures
mean = Sum of value(measures)/10
Therefore, we are going to have 20 measured and 10 used to calculate the sample mean and the sample variance.
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.
