What is the nearest whole numbers of 3.41

1 answer:

6 0

You get the nearest whole number by rounding if the number is 5 or more you round up 4 or less round down...in this case you're rounding the decimal and the first number after the decimal is 4 so you round to....

2.A production process manufactures items with weights that are normally distributed with mean 10 pounds and standard deviation

Vesna [10]

Answer:

Step-by-step explanation:

Given that:

population mean = 10

standard deviation = 0.1

sample mean = 9.8 < x > 10.2

The z score can be computed as:

$z = \dfrac{\bar x - \mu}{\sigma}$

if x > 10.2

$z = \dfrac{10.2- 10}{0.1}$

$z = \dfrac{0.2}{0.1}$

z = 2

If x < 9.8

$z = \dfrac{9.8- 10}{0.1}$

$z = \dfrac{-0.2}{0.1}$

z = -2

The p-value = P (z ≤ 2) + P (z ≥ 2)

The p-value = P (z ≤ 2) + ( 1 - P (z ≥ 2)

p-value = 0.022750 +(1 - 0.97725)

p-value = 0.022750 + 0.022750

p-value = 0.0455

Therefore; the probability of defectives = 4.55%

the probability of acceptable = 1 - the probability of defectives

the probability of acceptable = 1 - 0.0455

the probability of acceptable = 0.9545

the probability of acceptable = 95.45%

4.55% are defective or 95.45% is acceptable.

sampling distribution of proportions:

sample size n=1000

p = 0.0455

The z - score for this distribution at most 5% of the items is;

$z = \dfrac{0.05 - 0.0455}{\sqrt{\dfrac{0.0455\times 0.9545}{1000}}}$

$z = \dfrac{0.0045}{\sqrt{\dfrac{0.04342975}{1000}}}$

$z = \dfrac{0.0045}{\sqrt{4.342975 \times 10^{-5}}}$

z = 0.6828

The p-value = P(z ≤ 0.6828)

From the z tables

p-value = 0.7526

Thus, the probability that at most 5% of the items in a given batch will be defective = 0.7526

The z - score for this distribution for at least 85% of the items is;

$z = \dfrac{0.85 - 0.9545}{\sqrt{\dfrac{0.0455\times 0.9545}{1000}}}$

$z = \dfrac{-0.1045}{\sqrt{\dfrac{0.04342975}{1000}}}$

z = −15.86

p-value = P(z ≥ -15.86)

p-value = 1 - P(z < -15.86)

p-value = 1 - 0

p-value = 1

Thus, the probability that at least 85% of these items in a given batch will be acceptable = 1

What is the perimeter of an equilateral triangular lamina of side length 12 cm

Marina86 [1]

Answer:

It is 36 cm

Step-by-step explanation:

In equilateral triangle, all sides are equal.

${ \sf{perimeter = side + side + side}}$

but side = 12 cm

${ \sf{p = (12 + 12 + 12)}} \\ { \sf{p = 36 \: cm}}$

Describe the transformation from the graph of f(x)=x to the graph of g(x)=1/3x PLEASE HELP!!

andrew11 [14]

The graph is shifted down k k units. Vertical Shift: Down 3 3 Units. The sign of a adescribes the reflection across the x-axis. −a - a means the graph is reflected across the x-axis. Reflection about the x-axis: None. The value of a a describes the vertical stretch or compression of thegraph. a>1 a > 1
