**Solution :**

Mean time for an automobile to run a 5000 mile check and service = 1.4 hours

Standard deviation = 0.7 hours

Maximum average service time = 1.6 hours for one automobile

The z - score for 1.6 hours = [tex]$\frac{1.6-1.4}{0.7 / \sqrt{50}}$[/tex]

= 2.02

Now checking a normal curve table the percentage of z score over 2.02 is 0.0217

Therefore the overtime that will have to be worked on only 0.217 or 2.017% of all days.

If A is the center of the circle, then which statement explains how segment ED is related to segment FD?

**Answer:**

ED ≅ FD because segment EF is perpendicular to a radius of circle A.

**Step-by-step explanation:**

The statement that explains how ED is related to FD is: ED = FD because segment EF is **perpendicular** to a **radius** of **circle A**.

When a segment is **perpedicular **to the **radius** of a **circle**, it forms a **right angle** at the center of the segment that is intersected by the **radius** of the **circle**.

In the diagram given, based on what **perpedicular mean**, ED = FD because segment EF is **perpendicular** to one of the **radii**, DA, of the **circle**.

Therefore, the statement that explains how ED is related to FD is: ED = FD because segment EF is **perpendicular** to a **radius** of **circle A**.

Find the measure of ∠NED, not ∠CED.

**Answer:**

[tex] m\angle NED = 100\degree [/tex]

[tex] m\angle CED = 80\degree [/tex]

**Step-by-step explanation:**

By exterior angle theorem:

(9x - 8)° = (5x - 10)° + 50°

(9x - 8)° = (5x - 10 + 50)°

(9x - 8)° = (5x + 40)°

9x - 8 = 5x + 40

9x - 5x = 40 + 8

4x = 48

x = 48/4

x = 12

(9x - 8)° = (9*12 - 8)° = (108 - 8)° = 100°

[tex] \implies m\angle NED = 100\degree [/tex]

[tex] m\angle CED = 180\degree - 100\degree [/tex] (Linear pair angles)

[tex] \therefore m\angle CED = 80\degree [/tex]

[tex]\huge{ \mathcal{ \underline{ Answer }}}\: ✓ [/tex]

Measure of Exterior Angle of a triangle is equal to the sum of measures of two opposite interior angles .

**Step-by-step explanation:**

I found the answer button.

The full height is 20, and the height of the parallelogram is 10. So that means the triangles height is 20-10=10. The top and bottom sides of a parallelogram are the same, so the base of the triangle is 18-(6+5)=7. So the area of the triangle is (7x10)/2=35. The area of a parallelogram can be count that same way as a regular rectangle. So 18x10=180. Putting those two together, 35+180=215.

Answer:

Quadratic model

Step-by-step explanation:

Given the data :

(0.1). (1, - 2), (2, - 3), (3,-2), (4.1)

The above data point when plotted using technology gives a quadratic model with the equation : x² - 4x + 1

With the quadratic regression model for the data above, we obtain a correlation Coefficient of 1 ; which means a perfect relationship exists between the x and y variables.

The answer is :

16+d=74

16+d=74

“Sum” is the answer to an addition problem

“Is” always means equals (=)

“d” is the variable representing Delia’s height

So the answer is:

16+d=74

“Is” always means equals (=)

“d” is the variable representing Delia’s height

So the answer is:

16+d=74

A triangle has vertices (0, 2), (3, 1), and (6.2). What is the approximate perimeter of the triangle? Round your answer to the nearest hundredth.

**Answer:**

6 + 2√10 units.

**Step-by-step explanation:**

We can use the distance formula to find the distance between the points. The points are ,

(0,2)(3,1)(6,2)Distance 1 :-

=> D₁ = √{ (x₁ - x₂ )² + ( y₁ - y₂ )² }

=> D₁ = √{ (0-3)² + (2-1)² }

=> D₁ = √{ 3² + 1² }

=> D₁ = √{ 9+1}

**=****>**** ****D****₁ **** ****=**** ****√****1****0**** **

Distance 2:-

=> D₂ = √{ (x₁ - x₂ )² + ( y₁ - y₂ )² }

=> D₂ = √{ (6-3)² + (2-1)² }

=> D₂ = √{ 3² + 1² }

=> D₂ = √{ 9 + 1}

**=****>**** ****D****₂**** ****=**** ****√****1****0**** **

Distance 3 :-

=> D₃ = √{ (x₁ - x₂ )² + ( y₁ - y₂ )² }

=> D₃ = √{ (6-0)²+(2-2)²

=> D₃ = √6²

**=****>**** ****D****₃**** ****=**** ****6**** **

→ Perimeter = D₁ +D₂ + D₃

→ Perimeter = √10 + √10 + 6

**→**** ****Perimeter**** ****=**** ****6**** ****+**** ****2****√****1****0**** ****units **
