4.70
x 6 ( lbs)
28.20

4.70 divided by 2 is 2.35

28.20 +2.35 = 30.55

Write an example of an equation that’s represents exponential decay

seropon [69]

The equation for exponential decay is given as y = a(1 - r)^x.

<u>Explanation:</u>

The formula for original exponential decay is y = ab^x.

The growth rate (r) is determined as b = 1 + r.

The decay rate (r) is determined as b = 1 - r.

y = ab^x (Where b = 1 - r)

y = a(1-r)^x

a represents the initial value

r represents growth or decay rate

x represents the number of time intervals that have passed.

<em>For example</em>

The population of Home Town is 2016 was estimated to be 35,000 people with an annual rate of increase of 2.4%.

The equation for decay factor y = 35000(1 - 0.024)^x

y = 35000(0.976). (where x = 1)

I am pretty sure you can only make one.
If two sides are known, and one of the angles, then the other bits can be deduced and are fixed.

The area of a playground is 12 square yards. The length of the playground is 3 times longer than its width. Find the length and

marishachu [46]

Answer:

Width is 2 and Length is 6

Step-by-step explanation:

As the data is given, the area of a playground is 12 square yards.
The length of the playground is 3 times longer than its width.
Let width is x, length is 3 times therefore, length = 3x

As we know the formula for area,

Area=length x width.

So by putting values in this formula,

12sq = (3x)(x)

=> 3x2 = 12

=> x2 = 12/3,

=> x2 = 4 ,

by taking square root we get x= 2,

the width is 2 and length is 3 times hence, length is 3(2) = 6.

Let X be a Bernoulli rv with pmf as in Example 3.18. a. Compute E(X2 ). b. Show that V(X) 5 p(1 2 p). c. Compute E(X79).

spayn [35]

The Bernoulli distribution is a distribution whose random variable can only take 0 or 1

The value of E(x2) is p
The value of V(x) is p(1 - p)
The value of E(x79) is p

<h3>How to compute E(x2)</h3>

The distribution is given as:

p(0) = 1 - p

p(1) = p

The expected value of x2, E(x2) is calculated as:

$E(x^2) = \sum x^2 * P(x)$

So, we have:

$E(x^2) = 0^2 * (1- p) + 1^2 * p$

Evaluate the exponents

$E(x^2) = 0 * (1- p) + 1 * p$

Multiply

$E(x^2) = 0 +p$

Add

$E(x^2) = p$

Hence, the value of E(x2) is p

<h3>How to compute V(x)</h3>

This is calculated as:

$V(x) = E(x^2) - (E(x))^2$

Start by calculating E(x) using:

$E(x) = \sum x * P(x)$

So, we have:

$E(x) = 0 * (1- p) + 1 * p$

$E(x) = p$

Recall that:

$V(x) = E(x^2) - (E(x))^2$

So, we have:

$V(x) = p - p^2$

Factor out p

$V(x) = p(1 - p)$

Hence, the value of V(x) is p(1 - p)

<h3>How to compute E(x79)</h3>

The expected value of x79, E(x79) is calculated as:

$E(x^{79}) = \sum x^{79} * P(x)$

So, we have:

$E(x^{79}) = 0^{79} * (1- p) + 1^{79} * p$

Evaluate the exponents

$E(x^{79}) = 0 * (1- p) + 1 * p$

Multiply

$E(x^{79}) = 0 + p$

Add

$E(x^{79}) = p$

Hence, the value of E(x79) is p
