The coordinates of each point are:
- A (5,2)
- B (2,0)
- C (1, -4)
- D (-5, 2)
- E (0, 6)
- F (-8, -8)
The quadrant or axis where the points are located are:
- A - I quadrant
- B - x-axis
- C - IV quadrant
- D - II quadrant
- E - y-axis
- F - III quadrant
Answer and explanation:
If Sam's base rate is $9 per hour and his hourly rate is $4 per hour initially. If he receives pay rises of 4% and 5% on hourly and base rate respectively, his new hourly rate and base rate would be:
105/100×9= $9.45
104/100×4= $4.16
Assuming normal working hours for a week(mon-fri) =.40 hours
Then Sam worked an extra 2 hours
His base pay= 40×$9.45= $378
Extra Hourly pay = 2×$4.16= $8.32

The coefficient is the number in front of the value.
The margin of error is defined as
where
σ = population standard deviation
n = sample size
z* = aconstant that depends on the confidence level.
At the 95% confidence level, z* = 1.96.
The confidence interval is calculated as
(μ - E, μ + E)
Given:
μ = 3, the mean number of pets,
E = 2.5, margin of error at the 95% confidence level.
Therefore the 95% confidence interval is
(3 - 2.5, 3 +2.5) = (0.5, 5.5)
Because we can only count whole numbers of pets, the confidence interval is (0, 5).
Answer:
At the 95% confidence level, the 5th graders own between 0 and 5 pets.
The distance between two points is P₁(d, q) and P₂(0, 0) is √(d²+ q²).
<h3>What is the distance between two points?</h3>
The distance between two points is defined as the length of the line segment between two places representing their distance. Most significantly, segments that have the same length are referred to as congruent segments and the distance between two places is always positive.
Given that the points P₁(d, q) and P₂(0, 0)
The formula of the distance between two points is P₁(d, q) and P₂(0, 0) is given by:
d (P₁, P₂) = √ (0 – d)² + (0 – q)²
d (P₁, P₂) = √(d²+ q²)
Hence, the distance between two points is P₁(d, q) and P₂(0, 0) is √(d²+ q²).
