GEOMETRIC PROBABILITY URGENT?

Mathematics
1 answer:
morpeh [17]3 years ago
5 0

Find tha area of large and small squares:

A_{large}=15.2\cdot 15.2=231.04,\\ A_{small}=5.98\cdot 5.98=35.7604.

The shaded region has area A_{shaded}=A_{large}-A_{small}=231.04-35.7604=195.2796.

Use the geometric probability to determine the probability that randomly selected point will be in the shaded region:

Pr=\dfrac{A_{shaded}}{A_{large}}=\dfrac{195.2796}{231.04}= 0.8452.

In percent 0.8452 is 84.52%. Round 84.52% to the nearest tenth and get 84.5%.

Answer: 84.5%

Apply the distributive property to create an equivalent expression.
rjkz [21]

Answer:

4x-8+4y

Step-by-step explanation:

We are given that an expression

4(x-2+y)

We have to find an equivalent expression using distributive property .

Distributive property:

a\cdot (b+c)=a\cdot b+a\cdot c

Using the property

4(x-2+y)=4(x-2)+4\cdot y

4(x-2+y)=4x+4(-2)+4y

4(x-2+y)=4x-8+4y

Hence, the equivalent expression  of the given expression is given  by

4x-8+4y

Identify the horizontal asymptote of f(x) = quantity 2 x minus 1 over quantity x squared minus 7 x plus 3. y = 0 y = 1 over 2 y
Ratling [72]
The horizontal asymptote is the value at the y-axis where the graph approaches the line but not necessarily touching it. Hence, the asymptotic characteristic of the graph. The standard form of a function in fraction form is y = (ax^n +...)/(bx^m+...). There are rules to follow to determine the horizontal asymptote of a function.
1) if n = m , then the horizontal equation is y = a/b
2) if n>m, then there is no horizontal equation
3) if n<m, then the horizontal equation is the x axis ; y = 0.

The function given falls on the third rule hence the horizontal asymptote of the function is at y = 0.

Im having a hard time on this question and I hope you can help.
Masja [62]

The answer would be x ≠ 0

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

First start with the left side, doing distributive property

So... -2(x) = -2x and -2(5) = -10 Therefore on the left side you now have -2x -10

Next do the same on the right side

-2(x) = - 2x and -2(-2) = 4 so you have -2x + 4 + 5 and you add 4 and 5, leaving you with -2x + 9

Now that you have simplified both sides the problem now looks like this:

-2x - 10 = -2x + 9

Because you have equal terms on both sides (-2) those cancel out so you have -10 = 9

Just from looking at this we know that the statement is false because -1o does not equal 9

*The symbol, "≠" means not equal to"

Talja [164]

Answer:

1. 7

2. 5/8

3. 5

4. 20

Step-by-step explanation:

There is one burger that weighs 3/8 pounds, four that weigh 1/2 pound, and two that weigh 3/4 pounds. The difference between the heaviest and the lightest is 3/4-1/8=5/8. The total combined weight is 5 pounds. 5/ 1/4= 5*4=20. Hope this helps!
