Children-a will allows you to provide for children and the special needs of a loved one.You decide how your assets will be distributed on your death.Smart tax planning- a will can ensure the minimum amount of tax going to the State, unlike in an intestacy situation where there is no discretion.you choose who handles your affairs on death rather than having the law decide.It is cheaper and faster to administer your estate with a will, rather than an intestacy.Making a Will is a responsibility you owe to both yourself and your family. It is a legal document that lets you decide what happens with your estate after you die.

In a class of 147 students, 95 are taking math (M), 73 are taking science (S), and 52 are taking both math and science. One student is picked at random. Find each probability.
P(taking math but not science)
Answer:
The probability that a student taking only math will get picked is approximately 29%
Step-by-step explanation: This is because out of the total number of students taking math (95), 52 of such students are also taking science. In order to get the number of students only taking math you have to do 95-52=43 and to put that against the amount of total students the ratio would be 43:147 or 42/147 and if you plug 42/147 into a calculator you will recieve a long decimal that you can then round to 29%.

Step-by-step explanation:
find the volume thank you :)
Answer:
160 ft^3
Step-by-step explanation:
volume = 1/3 * base area * height
volume = 1/3 * (8*6) * 10
volume = 1/3 * (48) * 10
volume = 16 * 10
volume = 160

For the function f (x) = 4x - e determine
X such that f (x) 0
Answer:
derivative is a function which measures the slope. It depends upon x in some way, and is found by differentiating a function of the form y = f (x). When x is substituted into the derivative, the result is the slope of the original function y = f (x).
There are many different ways to indicate the operation of differentiation, also known as finding or taking the derivative. The choice of notation depends on the type of function being evaluated and upon personal preference.
Suppose you have a general function: y = f(x). All of the following notations can be read as "the derivative of y with respect to x" or less formally, "the derivative of the function."
f'(x) f' y' df/dx dy/dx d/dx [f(x)].
[HINT: don't read the last three terms as fractions, read them as an operation.
For example, read: " dx/dy = 3x"
As: "the function that gives the slope is equal to 3x"
Let's try some examples. Suppose we have the function : y = 4x3 + x2 + 3.
After applying the rules of differentiation, we end up with the following result:
dy/dx = 12x2 + 2x.
How do we interpret this? First, decide what part of the original function (y = 4x3 + x2 + 3) you are interested in. For example, suppose you would like to know the slope of y when the variable x takes on a value of 2. Substitute x = 2 into the function of the slope and solve:
dy/dx = 12 ( 2 )2 + 2 ( 2 ) = 48 + 4 = 52.
Therefore, we have found that when x = 2, the function y has a slope of + 52.
Now for the practical part. How do we actually determine the function of the slope? Almost all functions you will see in economics can be differentiated using a fairly short list of rules or formulas, which will be presented

A hot air balloon is 1,200 feet above the ground. The angle of depression from the basket of the hot air balloon to the base of a monument is 54°.
Which equation can be used to determine the distance, d, in feet, from the basket of the hot air balloon to the base of the monument?
Answer:
c
Step-by-step explanation:
And The opposite of the 54 is 1200s. That 1200 go on top and then below the hypothesis D. So Since it's opposite of hypotenuse opposite over hypotenuse, we signed 54 is 1200 over d. Here's what he says, Another way to look at this is like this 1200 Indians. This dash line drew is also 1200 And when it comes to this 54° angle, it's the same thing opposite. 1200 divided by the hypothesis of D.

Answer:
2.5 gallons of gasStep-by-step explanation:
Note : we have a proportional relationship between the two variables
_______________________________________
He used 3/4 gallon of gas to mow 3/10 of the lawn
Then
He has to use 1/4 gallon of gas in order to mow 1/10 of the lawn
( we divided both sides by 3)
Then
He has to use 10 × 1/4 gallons of gas to mow 10/10 of the lawn
What that means is :
He has to use 10/4 gallons of gas to mow the entire lawn
In other words :
He has to use 2.5 gallons of gas to mow the entire lawn

What is the probability?
Probability is used to calculate the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
The probability of picking a chocolate-covered cherry is zero because there is no chocolate-covered cherry in the bag.
The probability that an a fell on the floor = number of a in the letter / total number of letters

The probability that an s or a o would be picked is = (number of s in the letter / total number of letters) + (number of 0 in the letter / total number of letters)
