Answer:
Range = (237100, 292900)
Step-by-step explanation:
Using Chebyshevs Inequality:
[tex]P(|X - \mu | \le k \sigma )\ge 1 -\dfrac{1}{k^2}= 0.889[/tex]
[tex]1 -\dfrac{1}{k^2}= 0.889[/tex]
[tex]\dfrac{1}{k^2}= 1- 0.889[/tex]
[tex]\dfrac{1}{k^2}=0.111[/tex]
[tex]k = \sqrt{\dfrac{1}{0.111}}[/tex]
[tex]k \simeq 3[/tex]
Thus, 88.9% of the population is within 3 standard deviation of the mean with the Range = μ ± kσ
where;
μ = 265000
σ = 9300
Range = 265000 ± 3(9300)
Range = 265000 ± 27900
Range = (265000 - 27900, 265000 + 27900)
Range = (237100, 292900)

Answer:
a=169 ft
Step-by-step explanation:
Here you are given the angle 25, and the opposite and hypotenuse values.
Opposite/Hypotenuse: the sin(angle 25)=a/400ft.
We need to solve for a, so lets multiply 400 to the other side:
400(sin25)=a. Plug this into your calculator and you will get the answer: a=169.04 ft

Approximately 6.5x10^7 people fly commercially in the United States each month. Approximately how many fly commercially each year?
The number of people that travel commercially each year is 7.8 x 10^8.
How many fly commercially each year?The number of people that travel commercially each year is represented in scientific notation. Scientific notation is used to compress larger numbers into smaller numbers. In order to write a number in scientific notation, the number is written as a decimal number, between 1 and 10 and multiplied by a power of 10.
In order to determine the number of people who flew commercially each year, multiply the number of people who flew each month by 12.
Number of people who fly commercially each year = 6.5x10^7 x 12
= 78 x 10^7
= 7.8 x 10^8

What is an equation of the line that passes through the point (1,-3) and is perpendicular to the line x+3y=21?
Answer:
x + 3y =21 equation 1
let the equation perpendicular to X + 3y = 21 be
3x - y + k = 0 equation 2
since the point ( 1 , -3 ) passes through equation 3x - y +k =0
3× 1 - (-3) + k = 0
or, 3 + 3 + k = 0
or, 6 + k =0
or, k = -6
now,
putting the value of k in equation 2
3x - y + k = 0
or, 3x -y -6=0

What Is The Difference Between 1+1 And 1x1?
Answer:
1+1=2 and 1x1= 1
Step-by-step explanation:
If you add something you take the first number and add it to the second one. If it is multiplication, you take the first number, and multiply by itself, so it would be 1 times itself (1) and it is kind of like 1+0 which equals 1. It doesn't sound like a lot, but when you get into Algebra and Pre-Algebra, etc. it does come along easier.
Answer:
1+1=2 and 1x1= 1

Answer:
The statement at the top says that the triangles are 'similar'. That means that the corresponding angles are equal, and each pair of corresponding sides have the same ratio. From the 4 and the 8, you can see that each side in the small one is 1/2 the length of the corresponding side in the big one. So the missing sides are 1/2 the length of the 7 and the 12.
Roberto uses 150 roses, 120 lilies, and 45 hydrangeas to make bouquets. Each bouquet has the same number of roses, the same number of lilies, and the same number of hydrangeas. i What is the maximum possible number of bouquets he can make? ii How many roses, lilies, and hydrangeas are in each bouquet?
Answer: (i) Maximum possible number of bouquets he can make = 15
(ii) There are 10 roses, 8 lilies and 3 hydrangeas in each bouquet.
Step-by-step explanation:
Given: Roberto uses 150 roses, 120 lilies, and 45 hydrangeas to make bouquets.
(i) Maximum possible number of bouquets he can make = HCF(150, 120 , 45)
Since , 150 = 2 x 3 x 5 x 5 , 120= 2 x 2 x 2 x 3 x 5 , 45 = 3 x 3 x 5
HCF(150, 120 , 45) = 3 x 5 = 15
Now, Maximum possible number of bouquets he can make = 15
(ii) Number of roses in each bouquet = [tex]\dfrac{150}{15}=10[/tex]
Number of lilies in each bouquet = [tex]\dfrac{120}{15}=8[/tex]
Number of hydrangeas in each bouquet =[tex]\dfrac{45}{15}=3[/tex]
Hence, there are 10 roses, 8 lilies and 3 hydrangeas in each bouquet.

It is found that the Statement 1 is true. The Statement 2 is false. The Statement 3 is true.
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
Given that V (T) represent the value of a bank account, and thousands of dollars, T years after the account is open at the bank.
The following statements can be considered true or false in the case;
V(0) = 2 means that the value of the bank account when it is opened is; $2000. Thus, it is TRUE
V(5) = 2.2 means that 2.2 years after the bank account is opened, its value is; $5000. Thus, it is FALSE
V(10) – V(5) = 0.4 means that the bank account grows by, $400 between 5 and 10 years after its opening. Thus, it is TRUE
The function takes the form as given below.
V(t) = Value of account.
Hence, The Statement 1 is true.
The Statement 2 is false.
The Statement 3 is true.
