Answer:

8.885

Step-by-step explanation:

Given that :

Sample size, n = 10

The average range, Rbar for all samples = 5

The upper control limit, UCL for the R-chart is :

UCL L= D4Rbar

From the control chart constant table, D4 = 1.777

Hence,

UCL = 1.777 * 5

UCL = 8.885

The UCL for the R-chart is 8.885

A student claims that the expression “9 times the sum of a number and 13” is translated to the algebraic expression 9n + 13. Is
Vanyuwa [196]

Answer: The student is wrong. The correct algebraic expression is 9(n + 13)

The algebraic expression is represented as follows:

The sum of a number and 13 is represented as follows:

Let

n = the number

Therefore,

The sum of a number and 13 is:

n + 13

9 times the sum of a number and 13” can be translated as follows:

9(n + 13)

Therefore, the student is wrong.

If KL = 8 and KM = 12, what is KN? Round your answer to the nearest tenth.
WITCHER [35]

Answer:

5.3

Step-by-step explanation:

Use the right triangle altitude theorem.

KM/KN = KL/KN

12/8 = 8/KN

1.5 = 8/KN

1.5KN = 8

KN = 8/1.5

KN = 5 1/3

Find the measure of each angle if c||d show work
weeeeeb [17]

Answer:

Part a) <1=72°

Part b) <2=108°

Part c) <3=72°

Part d) <4=108°

Step-by-step explanation:

step 1

Find the measure of angle 1

we know that

<1+108°=180° -----> by supplementary angles

so

<1=180°-108°=72°

step 2

Find the measure angle 2

we know that

<2=108° -----> by corresponding angles

step 3

Find the measure angle 3

we know that

<3=<1-----> by corresponding angles

so

<3=72°

step 4

Find the measure angle 4

we know that

<4=108° -----> by alternate exterior angles
