The top one is 290° since a circle is 360° and you take away 70° from that you get 290

the second one is 93-25=68 and then 68÷2=34 so 34°

The period T (in seconds) of a pendulum is given by T=2\pi \sqrt((L)/(32)), where L stands for the length (in feet) of the pendu

Vsevolod [243]

The first thing we must do in this case is to rewrite the equation correctly:
T = 2 * pi * root (l / 32)
From here, we clear l:
T / (2 * pi) = root (l / 32)
l / 32 = (T / (2 * pi)) ^ 2
l = 32 * (T / (2 * pi)) ^ 2
Substituting values:
l = 32 * (1.57 / (2 * 3.14)) ^ 2
l = 2 feet
Answer:
the length is:
l = 2 feet

What is the value of x? Trigonometry A) 26.35 B) 26.9 C) 51.96 D) 65.58

maria [59]

Step-by-step explanation:

By Sine Rule,

x/sin42° = 37/sin110°.

Hence x = 37sin42°/sin110° = 26.35 in. (A)

Suppose that a process is currently operating at a 3.5-sigma quality level, and it is planned to use improvement projects to mov

jenyasd209 [6]

Answer:

$11,373 PPM$

Step-by-step explanation:

The following formula is used to compute the Proportion of error-free units given the sigma level in Excel.

The proportion of error-free units = NORMSDIST(Sigma Level - 1.5)

Suppose that a process is currently operating at a 3.5-sigma quality level.

The proportion of error-free units for this process is

NORMSDIST(3.5 - 1.5) = 0.977250

Therefore, the rejection rate is equal to

$1 - 0.977250 = 0.022750$

or 22750 PPM.

Now, consider a 6-sigma level process.

The proportion of error-free units equals

NORMSDIST(6.0 - 1.5) = 0.9999966

and the rejection rate is

$1 - 0.9999966 = 3.4 PPM$

Hence, reduction is PPM required per year , that is

$\dfrac{22750 - 3.4}{2} = 11,373 PPM$

reduction per year
