If you're trying to find the volume then you'd multiply your Length× Width× Height. so V= L×W×H. By plugging in your numbers it would be.
V= 20 × 20 × 15. All that multiplied would be equal to.. 6,000 cubic in. That would be your formula.

If you're looking for area then it would just be..
$a = l \times w$
which is 20 × 20 = 400 square in.

The amount of time that a surveillance camera will run without having to be reset is a random variable having the exponential di

Evgesh-ka [11]

Answer: The required time is 0.743.

Step-by-step explanation:

Since we have given that

$\lambda=0.02$

We need to find the time above which is 68% of the cameras have to be reset.

So, exponential distribution would be

$f(x)=0.02e^{-0.02}$

So, it becomes,

$P(X$

Hence, the required time is 0.743.

PLEASE FOLLOW THE DIRECTIONS AND SHOW YOUR WORK. IM OFFERING 15PTS (Way more than its worth) AND BRAINLIEST ANSWER. PLEASE HELP

I'll take this challenge since I'm not feeling lazy for once.... x would represent Gavin and y would represent Seiji.

a. $x+y=425, x-y=25$

b. I will solve your system using substitution.
$x+y-425, x-y=25$
Step 1: Solve $x+y=425$ for x
$x+y+-y=425+-y$ (add -y for both sides)
$x=-y+425$
Step 2: substitute $-y+425$ for x in $x+b=25$
$x+y=25$
 $-y+425-y=25$
$-2y+425=25$ (simplify both sides of the equation)
$-2y+425+-425=25+-425$ (add -425 to both sides)
 $-2y=-400$
$\frac{-2y}{-2} = \frac{-400}{-2}$
y=200
step 3: substitute 200 for y in $x=-y+425$
$x=-y+425$
$x=-200+425
$
$x=225$
$x=225, y= 200$

c. Already answered with the picture that is attached.

d. Gavin earned 225 dollars while Seiji earned 200 dollars.
