A group of students collect a number of shells on the beach. They sort the shells into three piles based on the size of each shell. Pile 1 has half as many shells as the total amount they collected. Pile 2 has 10 fewer shells than the first pile. Pile 3 has the remaining shells. Write an expression that represents the number of shells in Pile 2.
Answer:
Three piles
Let No. of shells =S
pile1=0.5 S
pile2=0.5S-10
pile 3=10
The required expression is [tex]y=x-10[/tex]
Computation:
Let us that,
The number of shells in pile 1 be[tex]'x'[/tex]
The number of shells in pile 2 be [tex]'y'[/tex]
The number of shells in pile 3 be [tex]'z'[/tex]
Now,
The number of shells in pile 2 is 10 fewer than the number of shells in pile 1.
So, the expression is, [tex]y = x - 10[/tex]

What is the mean absolute deviation of the following set of data?
10
20
12
4
18
8
14
18
Answer:
The mean absolute deviation of the following set of data is 4.5
Step-by-step explanation:
We need to find the mean absolute deviation of the following set of data.
10,20,12,4,18,8,14,18
For finding mean absolute deviation, first we need to find the mean of the given data set.
The formula used to calculate mean is: [tex]Mean=\frac{Sum\:of\:all\:data\:points}{Number\:of\:data\:points}[/tex]
Sum of all data points: 10+20+12+4+18+8+14+18 = 104
Number of data points = 8
So, mean is:
[tex]Mean=\frac{Sum\:of\:all\:data\:points}{Number\:of\:data\:points}\\Mean=\frac{104}{8}\\Mean=13[/tex]
Now, we will subtract 13 from the given data points:
10 - 13 = -3
20 - 13 = 7
12 - 13 = -1
4 - 13 = -9
18 -13 = 5
8 - 13 = -5
14 - 13 = 1
18 - 13 = 5
We will take absolute values i.e |-a|=a
So, now the numbers will be:
3,7,1,9,5,5,1,5
We will now find absolute mean deviation by finding mean of newly calculate values
Sum of all data points = 3+7+1+9+5+5+1+5
Number of data points = 8
[tex]Mean=\frac{Sum\:of\:all\:data\:points}{Number\:of\:data\:points}\\Mean=\frac{36}{8}\\Mean=4.5[/tex]
So, the mean absolute deviation of the following set of data is 4.5

Question #3: Complete the statement below to show the correct value of 100%. Part A: The expression 100 3 = 10 because 100 = 102 and = 101 = 10. Po Part B: When simplified, the answer is rational irrational
Answer:
Step-by-step explanation:
Part A.
Expression [tex](100)^{\frac{1}{2}}[/tex] = 10
Because 100 = [tex](10)^{2}[/tex] and [tex][(10)^2]^{\frac{1}{2}}=10^1=10[/tex]
[Since, [tex](a^{2})^{\frac{1}{2}}=a^{2\times \frac{1}{2}}=a^1[/tex]]
Part B.
When simplified, the answer is RATIONAL.
[Since, 10 can be written as [tex]\frac{10}{1}[/tex]]

Answer:
y = - 2x
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{1}{2}[/tex] x + 3 ← is in slope- intercept form
with slope m = [tex]\frac{1}{2}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{2} }[/tex] = - 2
The perpendicular line passes through the origin ⇒ c = 0
The equation of line L₂ is
y = - 2x + 0 , that is

A box of granola weighs 24 ounces and a box of bran flacks weighs 6/8 as much as the ronal A box of Corn Pops weighs 1 1/8 as much as the ronal what is the least number of ounces found in either box or ronal bran flakes or Corn Pops
Answer:
54 ounces
Step-by-step explanation:
A box of granola weighs 24 ounces and a box of bran flacks weighs 6/8 as much as the ronal
The number of ounces of the bran flakes = 6/8 of the box of the granola
= 6/8 × 24 ounces
= 18 ounces
A box of Corn Pops weighs 1 1/8 as much as the granola
Hence, the number of ounces of the box of corn pops =
1 1/8 of the granola box
= 9/8 × 24 ounces
= 27 ounces
The least number of ounces found in either box or ronal bran flakes or Corn Pops is calculated as:
We solve using LCM Method
Multiples of 18:
18, 36, 54, 72, 90
Multiples of 27:
27, 54, 81, 108
Therefore,
LCM(18, 27) = 54
The least number of ounces found in either box or ronal bran flakes or Corn Pops is 54 ounces

Given: x + 2 <-5.
Choose the solution set.
OXIXER,<-7)
OXIXERX <-3)
OxIXER X<3)
OXIXER X<7)
Answer:
The solution set is {x : x ∈ R, x < -7} ⇒ A
Step-by-step explanation:
The solution set of the inequality x > a is {x : x ∈ R, x > a}The solution set of the inequality x < a is {x : x ∈ R, x < a}The solution set of the inequality x ≥ a is {x : x ∈ R, x ≥ a}The solution set of the inequality x ≤ a is {x : x ∈ R, x ≤ a}Let us solve the question
∵ x + 2 < -5
→ Subtract 2 from both sides of the inequality
∴ x + 2 - 2 < -5 - 2
∴ x + 0 < -7
∴ x < -7
→ By using the second rule above
∴ The solution set is {x : x ∈ R, x < -7}
Suppose that scores on a particular test are normally distributed with a mean of 140 and a standard deviation of 18. What is the minimum score needed to be in the top 5% of the scores on the test? Carry your intermediate computations to at least four decimal places, and round your answer to one decimal place.
Answer:
153.16
Step-by-step explanation:
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score = ???
μ is the population mean = 140
σ is the population standard deviation = 8
Top 5% means the score is in the 95th percentile
The z score of 95th percentile = 1.645
1.645 = x - 140/8
Cross Multiply
1.645 × 8 = x - 140
13.16 = x - 140
x = 13.16 + 140
x = 153.16
Therefore, the minimum score needed to be in the top 5% of the scores on the test is 153.16

The cost, y y , for x x pounds of nails can be represented by the equation y=3.20x y = 3.20 x . What is the constant of proportionality of the equation?
Answer:
3.20
Step-by-step explanation:
If y is proportional to x as represented as;
y = 3.20x
This means that the relationship between y and x is a direct proportionality
y = kx
k is the constant of proportionality
Comparing with the given equation we will see that k = 3.20
Hence the constant of proportionality is 3.20
