How I would do it is place a point at 1 then go up 1 over 4 because of your slope 1/4. Same as for going down except down 1 over 4. Hope this helped:)

A vending machine operator has determined that the number of candy bars sold per week by a certain machine is a random variable

docker41 [41]

Answer:

The answer is below

Step-by-step explanation:

Let Y represent the profit per day, and x represent the number of bar sold per day. Hence:

Y = 0.25x - 2

a) The mean is given as:

$\mu_y=E(Y)=E(0.25X-2) = 0.25E(X)-2\\\\But\ E(X)=mean\ of\ machine=125. Hence:\\\\E(Y)=0.25(125)-2=29.25\\\\E(Y)=\$29.25$

b) The standard deviation of y is:

$\sigma_y=var(0.25X-2)\\\\\sigma_y=0.25\sigma(X)\\\\but\ \sigma_X=7,hence:\\\\\sigma_y=0.25(7)=1.75\\\\\sigma_y=\$1.75$

Can anyone help me with this page i can’t find the answers

Dvinal [7]

1) f(x)=2x

when x=3 then f(x) =3×2=6

when x=4 then f(x)=4×2=8

2)At y=35(no. of mangoes),x corresponds to y=60(amount)

so$60, amount he need to spend!

3) f(x)= x+2

for x=1, f(x)=1+2=3

for x=2,f(x)=2+2=4

Can someone help!!! And explain please

vlada-n [284]

Answer:

400(π+2) feet square

Step-by-step explanation:

let x be the diagonal of the cage=40√2 at the same time it is the radius of the circle ( the tiger can go in circle)

but since the cage is part of the circle and not full turn πr²/8

area of the circleπr²+ half area square

(π(40√2)²)/8 +40²/2

3200π/8+1600/2

400π+800

400(π+2) feet square
