Part 1

By the inscribed angle theorem, arc ZY measures 76 degrees.

Part 2

Since angles inscribed in the same arc are congruent, angle YXZ measures 38 degrees.

Part 3

Since diameters form semicircles and the arc of a semicircle measures 180 degrees, arc XYZ measures 180 degrees.

Part 4

Subtracting arc ZY from arc XYZ, we get 104 degrees.

6cos x-6sin x=3.sqrt6

Yakvenalex [24]

Divide by 6
$cos x - sin x = \frac{\sqrt{6}}{2}$

Square both sides
$cos^2 x -2 sin x cos x + sin^2 x = \frac{3}{2}$

Simplify Left side using Trig identities: (Pythagorean, Double Angle)
$1 - sin (2x) = \frac{3}{2}$

Solve for x:
$sin (2x) = -\frac{1}{2} \\ \\ 2x = \frac{7 \pi}{6}, \frac{11 \pi}{6} \\ \\ x = \frac{7 \pi}{12}, \frac{11 \pi}{12}$

While developing x-bar and R charts, the manager took 10 samples each of size 6. The average of sample means was 3.2. The averag

stiv31 [10]

Answer:

Option a. 1.2 is the correct answer

Step-by-step explanation:

Given the data in the question;

sample size n = 10

sub group = 6

The average of sample means x" = 3.2

Average range value R' = 0.6

the value of UCL for the R-chart = ?

To get the value of UCL for the R-chart, we say;

$UCL_R$ = D₄ × R'

from table of constants "Tabular values for x-bar and range charts

for size 6, the factor for control limits for range D₄ = 2.004

so we substitute

$UCL_R$ = 2.004 × 0.6

$UCL_R$ = 1.2024 ≈ 1.2

Hence, Option a. 1.2 is the correct answer.
