Answer:
[tex]\lambda=10000[/tex] miles
Step-by-step explanation:
We are given that
[tex]\beta=10000 miles[/tex]
Exponential distribution function
[tex]f(x)=\frac{1}{\beta}e^{-\frac{x}{\beta}}, x\geq 0[/tex]
0, otherwise
Using the formula
[tex]f(x)=\frac{1}{10000}e^{-\frac{x}{10000}},x\geq0[/tex]
0, otherwise
[tex]E(x)=\int_{-\infty}^{\infty}xf(x) dx[/tex]
Using the formula
[tex]\lambda=E(x)=\frac{1}{10000}\int_{0}^{\infty}xe^{-\frac{x}{10000}}dx[/tex]
[tex]\lambda=\frac{1}{10000}([-10000xe^{-\frac{x}{10000}}]^{\infty}_{0}+10000[-10000e^{-\frac{x}{10000}}]^{\infty}_{0})[/tex]
Using formula
[tex]\int u\cdot vdx=u\int vdx-\int (\frac{du}{dx}\int vdx)dx[/tex]
[tex]\lambda=\frac{1}{10000}(0-(10000)^2(0-1))=10000[/tex]
Hence, the value of [tex]\lambda=10000[/tex] miles

Answer:
x = 24.52
Step-by-step explanation:
Since this is a right triangle, use Pythagorean Theorem to solve for the hypotenuse.
Pythagorean Theorem: a² + b² = c²
24² + 5² = x²
576 + 25 = x²
601 = x²
√601 = x
If a number reads the same forwards or backwards, like 404 and 1221, then it's called a palindrome. The first palindrome greater than 9999 is 10 001. What is the fifth palindrome greater than 9999?
Answer:
The fifth Palindrome greater than 9999 is 10,401
Step-by-step explanation:
Here, we want to get the fifth palindrome greater than 9999
To get this, we are going to write out the palindromes that are greater than 9999
we have them as follows to the fifth
10,001
10,101
10,201
10,301
10,401
So the fifth Palindrome greater than 9999 is 10,401

If point A is located at -8 on a number line and point B is located at 3 what is the distance between the two points?
Answer:
5
Step-by-step explanation:
you just have to subtract 3 by 8 and then you get 5
Answer:
11
Step-by-step explanation:
You are finding the space between them so we are going to make them absolute values and then add them:
|-8| + |3| = 8+3 = 11
Write an equation of the locus of all points equidistant from the x axis and the y axis and whose coordinates have the opposite signs.
Answer:
y=-x
Step-by-step explanation:
Since the y-axis and x-axis are intersecting lines then you need to apply the locus of intersecting lines which would be the angle bisector and since the problem is asking for the opposite signs you need to make it -x instead of x.

Associative
Step-by-step explanation:
Suppose you have a population in which 60% of the people approve of gambling. Is the value 0.60 a parameter or a statistic
Answer:0.60 is a parameter .
Step-by-step explanation:
In statistics, a parameter is a number that summarize the data for a whole population.
On the other hand , statistic gives a measure for sample of population.
Given: We have a population in which 60% of the people approve of gambling.
60% = 0.60
Since it is a measure for the population , it is denoted as population parameter.
Hence, 0.60 is a parameter not statistic.
Helpppppp meeee please and thank you
What is the solution of the following systems of equations? y = 1/2x
y = -x -3
Answer:
x = -2, y = -1
Step-by-step explanation:
System of Equations
Solve the system:
y = 1/2x
y = -x - 3
Multiplying the first equation by 2:
2y = x
Substituting x in the second equation:
y = -2y - 3
Adding 2y:
3y = -3
y = -3/3
y = -1
And x = 2*(-1) = -2
Solution: x = -2, y = -1

In the figure below, k || o. Find the values of y and z.
Answer:
y = 112
z = 27
Step-by-step explanation:
Alright,
So we know that a straight line adds up to 180. And looking at the figure, it looks like 68 + y = 180 if you do some visualization.
So, we can already calculate y.
y = 180 - 68
y = 112
Now we find z. z here is represented in an expression. We can see that y and the expression z is in are congruent to each other which means they will equal each other. And since we know that y = 112, we know that the expression z is in is also equal to 112.
So we set up an equation like so:
112 = 3z + 31
And start to simplify:
81 = 3z
Finally we divide:
27 = z
Therefore, z is 27

A woman purchased a used car for $3,000. She decided to sell the car for 20% above her purchase price. She could not sell the car so she reduced asking price by 20%. If she sells the car at the reduced price, she will have a profit or a loss or will she break even?
10.1 #17
Answer:
She will have a loss of $ 120
Step-by-step explanation:
Purchase price of car = $ 3000
20% of 3000 = [tex]\frac{20}{100}*3000[/tex]
= 20 * 30
= $ 600
Selling price = 3000 + 600 = $ 3600
Reduction price = 20% of 3600
[tex]\frac{20}{100}*3600[/tex]
= 20 * 36
= $ 720
Current selling price after reduction = 3600 - 720
= $ 2880
Loss = 3000 - 2880
= $ 120

Step-by-step explanation:
Answer:
We are asked to find the area of the rectangle that has side lengths of 3/4 yard and 5/6 yard.
We know that area of rectangle is width times length.
To find the area of the given rectangle we will multiply both side length as:
Area of regatangle = width x Lenghth
Area of regtangle = 3/4 x 5/6 yard to the 2 power
Area of regtangle = 1/4 x 5/2 yard to the 2 power
Area of regtangle = 1 x 5/ 4x2 yard to the 2 power
Area of regtangle = 5/8 yard to the 2 power
Therefore, the area of the given rectangle would be 5/8 square yards.

As pointed out, you lose if the pile has 1, 6, 11 or 16 sticks. How many sticks are needed in the next two piles for you to lose
Answer:
21 and 26 totaling 47sticks
Step-by-step explanation:
Th number of sticks form an arithmetic progression
1, 6, 11, 16...
The nth term of an arithmetic progression is expressed as;
Tn = a+(n-1)d
a is the first term = 1
d is the common difference
d = 6-1 = 11-6 = 5
n is the number of terms
The next two terms are the fifth and sixth term
T5 = 1+(5-1)5
T5 = 1+4(5)
T5 = 1+20
T5 = 21
T6 = 1+(6-1)5
T6 = 1+5(5)
T6 = 1+25
T6 = 26
Hence the number of sticks needed in the next two piles are 21 and 26 totaling 47sticks
Use the Distributive Property to expand 2 (-3x + 5).
Answer:
-6x+10
Step-by-step explanation:
The distributive property states that multiplying each term will yield the same product as multiplying the sum. This means to expand this expression multiply both addends by 2 then add together. So, the new expression is, 2 * -3x + 2 * 5, which simplifies to -6x+10.
Answer:
Step-by-step explanation:
-6x+10
What is the area of the regular hexagon ABCEF? Explain your reasoning.
Answer:
1350[tex]\sqrt{3}[/tex] units²
Step-by-step explanation:
The regular hexagon consists of 6 equiangular triangles
The area (A) of a equilateral triangle is calculated as
A = [tex]\frac{s^2\sqrt{3} }{4}[/tex] ( s is the side length )
Here s = 30 , then
A = [tex]\frac{30^2\sqrt{3} }{4}[/tex] = [tex]\frac{900\sqrt{3} }{4}[/tex] = 225[tex]\sqrt{3}[/tex] units²
Thus the area of the regular hexagon is
area = 6 × 225[tex]\sqrt{3}[/tex]
= 1350[tex]\sqrt{3}[/tex] units² ← exact value
≈ 2338.3 units² ( to 1 dec. place )
Nathaniel's car used 10 gallons to travel 360 miles. How far can he travel on 16 gallons?
Answer:
16 gallons will get you 576 miles
Step-by-step explanation:
We use ratios to solve this question
10 gallons : 360 miles
Divide both sides by 10 to find 1 gallon
1 gallon:36 miles
multiply both sides by 16
16 gallons : 576 miles
Answer:
576 miles
Step-by-step explanation:
If Nathaniel's car uses 10 gallons to travel 360 miles, then the car can drive 36 miles per 1 gallon (360/10=36).
If he has 16 gallons and he can drive 36 miles per gallon, he can travel 576 miles (36*16=576).
