The x value for the third quartile for this distribution is 106.8
Z score
The z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:
z = (x - μ) / σ
where μ is the mean, x = raw score and σ is the standard deviation.
Given μ = 100, σ = 10.
The third quartile correspond with a z score of 0.675, hence:
0.675 = (x - 100) / 10
x = 106.8
The x value for the third quartile for this distribution is 106.8

A railroad track rises 10 feet for every 400
feet along the track. What is the measure-
ment of the angle the track forms with the
horizontal?
Answer:
1.43 degrees
Step-by-step explanation:
Think of this as a triangle with an x (horizontal) value of 400 and a y (vertical) value of 10.
Using this train of thought, we can use SOHCAHTOA to find that the tan of some angle (we will use Ф to represent this angle) is equal to the opposite (vertical) value divided by the adjacent (horizontal) value.
As an equation, it looks like this: tan (Ф) = 10/400.
We can use the arctan to find Ф from this equation: arctan (10/400) = Ф
Therefore, Ф is about 1.43 degrees.

The cat weighs 7 3/4 pounds.The cats weight is 2/3 the weight of the dog.How much does the dog weigh!
Answer:
11.625 pounds
Step-by-step explanation:
x = weight of dog
7 3/4 = 2/3(x)
7 3/4 divided by 2/3 = x
x = 11.625 pounds
Answer:
11 5/8
Step-by-step explanation:
let 'd' = dogs weight
7 3/4 equals 2/3d
change 7 3/4 to an improper fraction: 31/4
to isolate 'd', each side needs to be multiplied by 3/2
31/4 × 3/2 = d
93/8 = d
11 5/8 equals dogs weight

The value of x in the equation [tex]3^2^x = 9^3^x^-^4[/tex] is 2.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equation is [tex]3^2^x = 9^3^x^-^4[/tex]
We need to find the value of x.
We can write the given equation as below to make the bases same.
as 9 is equal to 3²
[tex]3^2^x = 3^2^(^3^x^-^4^)[/tex]
Apply distributive property in exponential part.
[tex]3^2^x = 3^(^6^x^-^8^)[/tex]
Now compare the exponential part as the bases are same
2x=6x-8
8=6x-2x
8=4x
Divide both sides by 4
x=2
Hence, the value of x in the equation [tex]3^2^x = 9^3^x^-^4[/tex] is 2.

4 tons of mulch cost $28,080.00 what is the price per pounds
Step-by-step explanation:
in the strange US system there is suddenly a metric relationship :
1 ton = 2000 pounds.
FYI - an actual (metric) ton is 1000 kg, which is
2,204.6226218488 pounds.
anyway, as 1 ton = 2000 pounds, then 4 tons = 4×2000 = 8000 pounds.
8000 pounds cost $28,080.00.
1 pound costs therefore
28080/8000 = $3.51

Nicole has a machine that will produce a number from 1 through 50 when she pushes a button. If she pushes the button, what is the probability of:
a. P(multiple of 10)
b. P(not 100)
C. P (not a multiple of 4)
d. P (one-digit number)?
Answer: Number from 1 through 50. 50 possible numbers. multiple of 10 : 10, 20, 30, 40, 50. 5 possible events. multiple of 4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48. 12 possible events one-digit number: 1, 2, 3, 4, 5, 6, 7, 8, 9. 9 possible events P(multiple of 10) = 5/50 or 1/10 P(not 100) = 50/50 or 1 P(not a multiple of 4) = 38/50 or 19/25 P(one-digit number) = 9/50
Answer: See below
Step-by-step explanation:
Test 1:
5 numbers that are a multiple of 10
Total amount of numbers = 50
Probability = 10/50
P = 1/5 or 20%
Test 2:
None of the numbers from 1 to 50 are 100, so obviously the probability will be 1 or 100%
Test 3:
12 multiples of 4 in all 50 numbers, since we want numbers that are not multiples of 4 we subtract the total number of them from 50
50 - 12 = 38
Probability = 38/50
P = 19/25 or 76%
Test 4:
There are 9 one-digit numbers in total
Probability = 9/50
P = 9/50 or 18%
Find the perimeter of the triangle whose vertices are the following specified points in the plane.
(0,−4),(−1,−2),(5,-3)
Answer:
Perimeter = 5.67
Step-by-step explanation:
AB = sqrt{-1 - (0)} + (-2 - (-4)}
Multiply -1 by 0
sqrt(-1 + 0 - 2 - (-4)
-1 by -4
sqrt(-1 + 0 - 2 + 4
Add -1 and 0
sqrt(-1 - 2 + 4)
Subtract 2 from -1
sqrt(-3 + 4)
Add
Sqrt(1) > 1
BC = sqrt{5 - (-1)} + {-3 - (-2)}
Multiply -1 by -1
sqrt(5 + 1 - 3 - (-2)
-1 by -2
sqrt(5 + 1 - 3 + 2
Add 5 and 1
sqrt(6 - 3 + 2)
Add 3 and 2
Sqrt(5) > 2.23
AC = sqrt{5 - 0} + {-3 - (-4)}
Multiply -1 by 0
sqrt(5 + 0 - 3 - (-4)
-1 by -4
sqrt(5 + 0 - 3 + 4)
Add 5 and 0
sqrt(5 - 3 + 4)
Subtract 3 from 5
sqrt(2 + 4)
Add
Sqrt(6) > 2.44
Perimeter = AB + BC + AC
Sqrt(1) + Sqrt(5) + Sqrt(6) = 1 + 2.23 + 2.44 = 5.67
