Answer:

11.218  - 11.812 feet

Step-by-step explanation:

The factory manager does not want to use the rods from the bottom 20% and the top 15%. In other words, the factory manager doesn't want percentile 0-20 and percentile 85-100.

To solve this question, you need to know the z score of percentile 20 and 85.  

Z-score of percentile 20 is -0.94, then the calculation will be :  

x=  11.5 feet+ 0.3 feet* z-score  

x=  11.5 feet+ 0.3 feet* (-0.94)

x=  11.5 feet-  0.282 feet

x=  11.218 feet  

Z-score of percentile 85 is +1.04 then the calculation will be :  

x=  11.5 feet+ 0.3 feet* z-score  

x=  11.5 feet+ 0.3 feet* 1.04

x=  11.5 feet+ 0.312 feet  

x=  11.812 feet

The range for the rod will be  11.218  - 11.812 feet

Calculate the perimeter to the nearest tenth​
fomenos

Answer: the perimeter is 40.9 ft

Step-by-step explanation:

The given figure is a trapezium. It is made up of a rectangle and a right angle triangle.

The perimeter of the trapezium is the distance around the figure. This means that the inner dimensions are not included.

Since the opposite sides of the rectangle are equal, it means that the base of the trapezium would be

10 + 4 = 14 ft

Therefore, the perimeter of the trapezium would be

8 + 10 + 8.9 + 14 = 40.9 ft

If AJKL = ARST, which congruences are true by CPCTC? Check all that apply.
evablogger [386]

Based on the CPCTC theorem, the congruences that are true about the given triangles are:

B. ∠K ≅ ∠S

C. KL ≅ ST

D. JK ≅ RS

<h3>What is the CPCTC Theorem?</h3>

According to the CPCTC theorem states that if two triangles are congruent to each other, then, all their corresponding parts will be congruent to each other.

Given that triangles JKL and RST are congruent to each other, therefore:

∠J ≅ ∠R

∠K ≅ ∠S

∠L ≅ ∠T

JK ≅ RS

KL ≅ ST

JL ≅ RT

Therefore, the congruences that would be true by CPCTC are:

B. ∠K ≅ ∠S

C. KL ≅ ST

D. JK ≅ RS
