The thickness of a ﬂange on an aircraft component is uniformly distributed between 0.95 and 1.05 millimeters. Determine the foll

Mrrafil [7]

Answer

given,

thickness of a ﬂange on an aircraft component is uniformly distributed between 0.95 and 1.05 millimeters.

X = U[0.95,1.05] 0.95≤ x ≤ 1.05

the cumulative distribution function of flange

F(x) = P{X≤ x}= $\dfrac{x-0.95}{1.05-0.95}$

= $\dfrac{x-0.95}{0.1}$

b) P(X>1.02)= 1 - P(X≤1.02)

= $1- \dfrac{1.02-0.95}{0.1}$

= 0.3

c) The thickness greater than 0.96 exceeded by 90% of the ﬂanges.

d) mean = $\dfrac{0.95+1.05}{2}$

= 1

variance = $\dfrac{(1.05-0.95)^2}{12}$

= 0.000833

Answer:

4096∠0°

Step-by-step explanation:

The polar form of the base value is 2∠120°. Then the 12-th power is ...

(2^12)∠(12×120°) = 4096∠0° . . . . or θ = 0 radians, as you wish

_____

I prefer the simpler notation r∠θ, rather than ...

r(cos(θ) +i·sin(θ)) or r·cis(θ) or r·e^(iθ)

You might not see this notation very often in areas outside of electrical engineering.

The time between a flash of lightning and the sound of its thunder can be used to estimate the distance you are from a lightning

julia-pushkina [17]

If you count the number of seconds between the flash of lightning and the sound of thunder, and then divide by 5, you'll get the distance in miles to the lightning: 5 seconds = 1 mile, 15 seconds = 3 miles, 0 seconds = very close. Keep in mind that you should be in a safe place while counting.

Wht is the value of x in the proportion 2 1/4 ÷ x = 1 1/4 ÷ 3 3/5

balandron [24]

Answer:

$x = \frac{162}{25}$

Step-by-step explanation:

You need to solve the equation for x.

First change all the mixed numbers to improper fractions. Remember that a improper fraction the numerator (top number) is larger than the denominator (bottom number).

$2\frac{1}{4} / x = 1\frac{1}{4} / 3\frac{3}{5}\\\$
