Answer:

X as an angle will be equal to 140°

Step-by-step explanation:

As AO = BO, AOB is an Isosceles triangle which has 2 equal angles OAB=OBA=20°, therefore BOA is equal to 140°

x is the angle opposite to BOA which will have the same angle measure.

Suppose that you collect data for 15 samples of 30 units each, and find that on average, 2.5 percent of the products are defecti

Korvikt [17]

Answer:

The UCL is $UCL = 0.054$

The LCL is $LCL \approx 0$

Step-by-step explanation:

From the question we are told that

The quantity of each sample is n = 30

The average of defective products is $p = 0.025$

Now the upper control limit [UCL] is mathematically represented as

$UCL = p + 3 \sqrt{\frac{p(1-p)}{n} }$

substituting values

$UCL = 0.025 + 3 \sqrt{\frac{0.025 (1-0.025)}{30} }$

$UCL = 0.054$

The upper control limit (LCL) is mathematically represented as

$LCL = p - 3 \sqrt{\frac{p(1-p)}{n} }$

substituting values

$LCL = 0.025 - 3 \sqrt{\frac{0.025 (1-0.025)}{30} }$

$LCL = -0.004$

$LCL \approx 0$

-(y + 2) + 8 = 3<br> I’m so confused on this, please send help

Hoochie [10]

Don't be worried friend :)

-(y + 2) + 8 = 3

=> -(y + 2) = -5

=> y + 2 = 5

=> y = 3
