Assuming that it's at the same angle the whole way, she goes 1.8 meters down in 3.1 meters down the slides, and if we divide 3.1 by 18 we can find how long the slide is for every 0.1 meter down, which is around 0.17. Multiplying that by 42, we get 7.23 (3 repeating) meters of the slide

Motorola used the normal distribution to determine the probability of defects and the number

vovangra [49]

Answer:

a.P<x<9.85 orx>10.15)=0.3174, Total defects=317.4

b.p=0.0026,total defects=2.6

c.Less of the items produced will be classified as defects.

Step-by-step explanation:

a.The standard score,z, is esentially x reduced by process mean then divided my process standard deviation.

$\mu=10,\sigma=0.15\\Therefore:-\\z=\frac{x-\mu}{\sigma}=\frac{9.85-10}{0.15}\approx-1.0\\z=\frac{x-\mu}{\sigma}=\frac{10.15-10}{0.15}\approx+1.0\\P(x10.15)=P(Z+1.0)\\=2P(Z$

Total defects=Production*Probability

=0.3174*1000

$=317.4$

b. $\mu=10,\sigma=0.05$

therefore:-

$z=\frac{x-\mu}{\sigma}=\frac{9.85-10}{0.05}\approx-3.0\\z=\frac{x-\mu}{\sigma}=\frac{10.15-10}{0.05}\approx+3.0\\\\=P(x10.15)=P(Z+3.0)\\=2P(Z$

Defects=Probability*Production

=0.0026*1000

=2.6

c.Reducing process variation results in a significant reduction in the number of unit defects.

The formula for the volume V of a cylinder is , where r is the radius of the base and h is the height of the cylinder. Select th

m_a_m_a [10]

Answer:

Step-by-step explanation:

V = π r² h

where r = 3 cm

V = 36π cm³

solve for h

plugin values into the formula:

36π = π 3² h

h = <u> 36π </u>

π 3²

h = 4 cm

a towns population has been decreasing at a constant rate. In 2007 the population was 5100. by 2011 the population had dropped t

Gelneren [198K]

75, because 300 (5100-4800) divided by 4 ( 2007-2011) is 75. The towns population decreased at a constant rate of 75.
