Answer:
Sigma is the eighteenth letter of the Greek alphabet. In the system of Greek numerals, it has a value of 200. In general mathematics, uppercase ∑ is used as an operator for summation. When used at the end of a letter-case word, the final form is used
Step-by-step explanation:
The greek letter sigma has many meanings and uses in math.
The uppercase form is written as [tex]\sum[/tex] which looks like a fancy or weird looking letter "E". This form indicates we'll be adding a bunch of items. They can be numbers or algebraic expressions.
The lowercase form is written as [tex]\sigma[/tex] which looks like a rotated letter "b" in a way. This lowercase form is often used for population standard deviations in statistics.
There are many other uses for this greek letter, so you'll need to provide more context and information to the question.

Debbie estimated that a caterpillar was 4.5 cm long. Later, she found its actual length to be 4.8 cm. Find the percent error.
Answer:
Percent error = 6.25%
Step-by-step explanation:
Percentage error can be defined as a measure of the extent to which an experimental value differs from the theoretical value.
Mathematically, it is given by this expression;
[tex] Percent \; error = \frac {experimental \;value - theoretical \; value}{ theoretical \;value} *100[/tex]
Given the following data;
Experimental value = 4.5cm
Theoretical value = 4.8cm
Substituting into the equation, we have;
[tex] Percent \; error = \frac {4.8 - 4.5 }{ 4.8} *100[/tex]
[tex] Percent \; error = \frac {0.3}{4.8} *100[/tex]
[tex] Percent \; error = 0.0625 *100[/tex]
Percent error = 6.25%

Select the 2 pairs of points so that the line between those points has slope 3/4. There are
2 choices that work!
A.
(0,5) and (-4,8)
B.
(6,-1) and (10,2)
C. (1,5) and (4,7)
D.
(0,5) and (-4,2)
E.
(-4,4) and (-1,7)
Answer:
D.
(0,5) and (-4,2)
E.
(-4,4) and (-1,7)
Step-by-step explanation:
To solve this problem, we apply the slope formula and compare with the known slope to see if the answer tallies;
Slope = [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]
A.
(0,5) and (-4,8)
x₁ = 0 y₁ = 5
x₂ = -4 y₂ = 8
Slope = [tex]\frac{8-5}{-4-0}[/tex] = [tex]-\frac{3}{4}[/tex]
B.
(6,-1) and (10,2)
x₁ = 6 y₁ = -1
x₂ = 10 y₂ = 2
Slope = [tex]\frac{10-6}{ 2-(-1)}[/tex] = [tex]\frac{4}{3}[/tex]
C.
(1,5) and (4,7)
x₁ = 1 y₁ = 5
x₂ = 4 y₂ = 7
Slope = [tex]\frac{7-5}{4-1}[/tex] = [tex]\frac{2}{3}[/tex]
D.
(0,5) and (-4,2)
x₁ = 0 y₁ = 5
x₂ = -4 y₂ = 2
Slope = (2-5) / (-4-0) = 3/4
E.
(-4,4) and (-1,7)
x₁ = -4 y₁ = 4
x₂ = -1 y₂ = 7
Slope = [tex]\frac{7-4}{-1-(-4)}[/tex] = [tex]\frac{3}{4}[/tex]
A road side vegetable stand sells pumpkins for $5 each and tomatoes for $3 each. The total sales on a certain day was $98. If they sold 10 pumpkins, write and solve a linear equation to find the number of tomatoes sold.
Answer:
98=50+3t
Step-by-step explanation:
5*10
50
98-50
48
48/3
16
The linear equation is 98 = 50+3t and the no of tomatoes sold is 16.
Given that,
A roadside vegetable stand sells pumpkins for $5 each and tomatoes for $3 each. The total sales on a certain day was $98. And, they sold 10 pumpkins.Here we assume the no of tomatoes sold be t.
Based on the above information, the calculation is as follows:
98 = 50+3t
98 - 50 = 3t
48 = 3t
t = 16
Therefore we can conclude that The linear equation is 98 = 50+3t and the no of tomatoes sold is 16.

Dee's clothing is having a discount of 40% on all shirts. Let x represent the regular price of any shirt in the store. Enter an expression that can be used to find the sale price of any shirt in the store.
Answer:
C=P-0.4xStep-by-step explanation:
Step one:
we want to find the expression for the cost of any type of shirt for an applied discount of 40%.
let the price of any shirt be P
let the cost of any shirt be x
and also the price after discount applied be C
Step two:
The discount is
=40/100*x
=0.4*x
=0.4x
Hence the cost of the shirt will be the initial cost minus the discount
C=P-0.4x

Step-by-step explanation:
you deposit $750 in a savings account the earns a 5% annual interest compounded quarterly.
a. write the function that represents the balance after t years.
b. what is the balance of the account after 4 years?
Answer:
a. [tex]A = P(1 + \frac{r}{n})^{nt}[/tex]
b .$914.85
Step-by-step explanation:
Step one:
given data
principal p=$750
rate= 5%= 0.05
for quarterly compounding n=4
a. the function that represents the balance after t years.
[tex]A = P(1 + \frac{r}{n})^{nt}[/tex]
A = final amount
P = initial principal balance
r = interest rate
n = number of times interest applied per time period
t = number of time periods elapsed
b. when t=4
[tex]A = 750(1 + \frac{0.05}{4})^{4*4}\\\\A= 750(1 +0.0125)^{16}\\\\A= 75(1.0125)^{16}\\\\A= 750*1.2198\\\\A=914.85[/tex]
A= $914.85
The function that represents the balance after t years is FV = $750( 1.0125)^4t.
The balance of the account after four years is $914.92.
What is the function that represents the balance after t years?The formula for calculating future value:
FV = P (1 + r)^nm
Where:
FV = Future value P = Present value R = interest rate = 5%/4 = 1.25% m = number of compounding = 4 N = number of yearsFV = $750( 1.0125)^4t
What is the account balance after 4 years?$750( 1.0125)^(4 x 4) = $914.92

Answer:
The angles from largest to smallest are:
∠A
∠B
∠C
Step-by-step explanation:
We can see in the diagram that
AB = 7
AC = 8
BC = 9
The angles opposite to sides are as follows:
∠A is opposite to BC
∠B is opposite to AC
∠C is opposite to AB
The angle opposite to the largest side of the triangle is the largest and the angle opposite to smallest side of the triangle is the smallest in measurement
Arranging the sides from largest to smallest:
BC, AC, AB
Similarly the angles opposite them will be arranged according to them
∠A, ∠B, ∠C
Hence,
The angles from largest to smallest are:
∠A
∠B
∠C
