ACME manufacturing company has developed a fuel-efficient machine that combines pressure washing with steam cleaning. It is adve

rtised as delivering 5 gallons of cleaner per minute. HOWEVER, a machine delivers an amount at random anywhere between 4.95 and 5.15 gallons per minute.Assume that Y, the amount of cleaner dispensed per minute, is a uniform random variable with probability density function [p.d.f.], f(y), given below. { 5 4.95 <= y <= 5.15f(y) = { { 0 otherwise(a) Find the probability that Y, the amount of cleaner dispensed per minute,is greater than 5 gallons per minute.(b) Find the expected value of Y, E(Y).(c) Find the variance value of Y, VAR(Y).

Answer:

a) 0.75

b)5.05

c)0.02

Step-by-step explanation:

a)

P(Y>5)=?

This part is solved in the given picture.

b)

The mean of a uniform distribution is (a+b)/2.

Where a=4.95 , b=5.15.

E(Y)=(4.95+5.15)/2

E(Y)=10.1/2

E(Y)=5.05.

c)

The variance of a uniform distribution is (b-a)²/2.

V(Y)=(5.15-4.95)²/2

V(Y)=0.2²/2

V(Y)=0.04/2

V(Y)=0.02.

Poppy, felix and Alexi sell 700 raffle tickets between them. Poppy sells twice as many tickets as Felix, and Alexi sells 25 more
slavikrds [6]
Let give Poppy = P, Felix = F, Alexi = A
so P+ F + A = 700 ----(1)
P = 2F ----(2)
A = 25 + P ---(3)
we will think in term of P

from (2) F = P/2

from (1) P + F + A = 700
P + P/2 + 25 + P = 700 ---(4)
(4) multiplied by 2
2P + P + 50 + 2P = 1400
5P + 50 = 1400
5P = 1350
so P = 270

so Poppy sold 270 tickets
Felix sold 135 tickets
and Alexi sold 295 tickets //

HELP FAST The circumference of the smaller circle is 30% of the circumference of the larger circle. Find the circumference of th
ollegr [7]

Answer

I attach the image of the circle in the picture below

Circumference larger circle = 62.831 in

Step-by-step explanation:

The perimeter of a circle is defined as

P = 2* pi* r

where

r corresponds to the radius of the circle.

In this case,

r = d/2 = 3 in

The perimeter of the smaller circle results

P1 = 2*(3.1416)*(3 in) = 18.8495 in

The circumference of the smaller circle is 30% of the circumference of the larger circle, so

P1 = 0.3* P2

P2 = 18.8495 in / 0.3 = 20\pi = 62.831 in
