Answer:
[tex]\huge\boxed{\sf k = 2}[/tex]
Step-by-step explanation:
Coordinate = (x,y) = (2k-1,k)
This means that:
x = 2k - 1 and y = k
Put it in the given equation: 5x - 4y = 7
5(2k-1) - 4k = 7
10k - 5 - 4k = 7
6k - 5 = 7
Adding 5 to both sides
6k = 7+5
6k = 12
Divide both sides by 6
k = 2

Ten voltage measurements in a circuit have produced the following values: 49.3, 50.1, 48.9, 49.2, 49.7, 50.5, 49.9, 49.3, 49.8, 50.2 If the standard deviation for the above data set is 0.50 V, Which of the values can be rejected:
Answers
Answer:
48.9 and 50.5 are rejected.
Step-by-step explanation:
Since the standard deviation shows the spread of the values of the voltages, we need to find the mean of the values and use the standard deviation to find the minimum and maximum voltage allowed.
So mean μ = Σx/N where x = individual values of voltage and N = number of values = 10
So, μ = Σx/N
= (49.3 + 50.1 + 48.9 + 49.2 + 49.7 + 50.5 + 49.9 + 49.3 + 49.8 + 50.2)/10
= 496.9/10
= 49.69
≅ 49.7 V
So, the acceptable values of voltage are in the range μ ± σ where σ = standard deviation = 0.50 V.
So, the acceptable values of voltage are in the range 49.7 ± 0.50 V
So, minimum value = 49.7 V - 0.50 V = 49.2 V
and maximum value = 49.7 V + 0.50 V = 50.2 V
So any voltage outside the range 49.2 V ≤ x ≤ 50.2 V is rejected.
There are two values outside this range which are 48.9 and 50.5. So these two values are rejected.

segment Y prime Z prime has endpoints located at Y'(0, 3) and Z'(−6, 3). segment YZ was dilated at a scale factor of 3 from the origin. Which statement describes the pre-image?
Answers
Answer:
YZ is located at Y (0, 1) and Z (-2, 1) and is one-third the size of Y'Z'.
Step-by-step explanation:
Since Y'Z' was dilated from the origin at a scale factor of 3, you can divide its X and Y coordinates by 3 to find the coordinates of YZ.
The statement fourth "segment YZ is located at Y (0, 1) and Z (−2, 1) and is one-third the size of segment Y prime Z prime" is correct.
What is dilation?The transformation dilation is used to resize an item. Dilation is a technique for making items appear larger or smaller. The image created by this transformation is identical to the original shape.
The question is incomplete.
The complete question is:
Segment Y prime Z prime has endpoints located at Y'(0, 3) and Z'(−6, 3). segment YZ was dilated at a scale factor of 3 from the origin. Which statement describes the pre-image?
segment YZ is located at Y (0, 9) and Z (−18, 9) and is three times the size of segment Y prime Z prime.segment YZ is located at Y (0, 3) and Z (−6, 3) and is the same size as segment Y prime Z prime.segment YZ is located at Y (0, 1.5) and Z (−3, 1.5) and is one-half the size of segment Y prime Z prime.segment YZ is located at Y (0, 1) and Z (−2, 1) and is one-third the size of segment Y prime Z prime.As we know, in the dilation image of the two-dimensional figure can be larger or smaller depending on the dilation factor.
We have:
segment Y prime Z prime has endpoints located at Y'(0, 3) and Z'(−6, 3).
After dilation:
Y (0, 1) and Z (−2, 1)
Thus, the statement fourth "segment YZ is located at Y (0, 1) and Z (−2, 1) and is one-third the size of segment Y prime Z prime" is correct.

Number of practice days in a week = 5
The total number of practice days.
= 5 x 5
= 25 days
Total time for 25 practice days = 37.5 hours.
The number of hours each practice day.
= 37.5 ÷ 25

Angle a is 5/3 of Angle b.
Find Angles a and b plz
Answers
Answer:
Angle a = 112.5°
Angle b = 67.5°
Step-by-step explanation:
Angle a + angle b = 180° (Supplementary Angles/angles on a straight line)
Let x = m<b
m<a = ⁵/3(x)
Therefore:
⁵/3x + x = 180
[tex] \frac{5x}{3} + x = 180 [/tex]
[tex] \frac{5x + 3x}{3} = 180 [/tex]
[tex] \frac{8x}{3} = 180 [/tex]
Multiply both sides by 3
[tex] \frac{8x}{3} \times 3 = 180 \times 3 [/tex]
[tex] 8x = 540 [/tex]
Divide both sides by 8
x = 67.5°
Angle a = ⁵/3(x) = ⁵/3(67.5) = 112.5°
Angle b = x = 67.5°
