a. The expected value is 0.40
b. The standard error is 0.0024
Given that:
Sample size, n=100
Population proportion, p=0.40
a) The expected value of the sample proportion is defined as:
E(^p)=p
now,
E(^p)=0.40
b) The standard error of the sample proportion is defined as:
SE(^p) = √p(1-p)/n
SE(^p) = √0.40(1-0.40)/100
SE(^p) = 0.0024
c) The sampling distribution of the sample proportion is normally distributed with the expected value of the sample proportion of 0.40.
Therefore,
E(^p) = 0.40
d) The central limit theorem states that the sample statistic (sample proportion) tends to the population parameter (population proportion) as the sample size tends to infinity (OR n→∞).
^P~N(p, p(-p)/n) as n→∞

The difference of two numbers is 16. The greater number is 4 times the smaller
number minus 5. Find the numbers.
After using the linear equation - The smaller number is 7, and the greater number will be 23.
what is the substitution method?
Mathematicians frequently use the substitution method to resolve an equation system. With this method, you solve the equation for the first variable first, and then plug the answer into the second equation.
what is a linear equation in two variables?
When an equation is written in the form axe + by + c=0 and the coefficients of x and y, i.e., a and b, respectively, are not equal to zero and the greater of the two numbers is four times the smaller number minus 5, that equation is said to be linear in two variables.
Let's assume that "x" is the smaller number, making "4x-5" the greater number. The requirement that the difference between the two numbers be 16 is also included.
thus,
4x - 5 - x = 16
3x -5 = 16
3x = 16 +5
3x =21
x = 21/3
x = 7
for the second number
4x-5
=4(7)-5
=28-5

hence the smaller number is 7, and the greater number will be 23.

A football team scored a total of 50 points in one game. They scored 14 times. The scoring
was made up of touchdowns (6 points each), field goals (3 points each), and PATS (1 point
each). They had 3 more touchdowns than field goals. How many of each type of score did the
team have?
Answer:
Touchdowns: 6
Field goals: 3
PATS: 5
Step-by-step explanation:
6*6 = 36
3*3 = 9
5*1 = 5
9+5+36 = 50 points
6+3+5 = 14 scored times
Answers:
6 touchdowns (TD)
3 field goals (FG)
5 points after touchdown (PAT)
===============================================
Explanation:
Acronyms used in football
PAT = point after touchdownTD = touchdownFG = field goalDefine the following variables
x = number of TDsy = number of FGsz = number of PATs"They had 3 more touchdowns than field goals", so,
TD = FG + 3
x = y + 3
They scored 14 times which means we can say
x+y+z = 14
Let's look at the point breakdown per type of score
TDs give 6 points each. Scoring x of them gives 6x pointsFGs give 3 points each. Scoring y of them gives 3y pointsPATs give 1 point each. Scoring z of them gives 1z pointsThen we can add up those expressions to get us to 6x+3y+1z = 50 points total. This is the same as saying 6x+3y+z = 50.
--------------------------
Here's our system of equations
x = y+3
x+y+z = 14
6x+3y+z = 50
Let's replace each x with y+3 in the second equation. Then solve for z.
x+y+z = 14
y+3+y+z = 14
2y+z = 14-3
2y+z = 11
z = 11-2y
Now replace every x with y+3 in the third original equation
6x+3y+z = 50
6(y+3)+3y+z = 50
6y+18+3y+z = 50
9y+z = 50-18
9y+z = 32
Then plug in z = 11-2y and solve for y
9y+z = 32
9y+11-2y = 32
7y+11 = 32
7y = 32-11
7y = 21
y = 21/7
y = 3 is the number of FGs scored
Use this to find z
z = 11-2y
z = 11-2(3)
z = 11-6
z = 5 is the number of PATs scored
Now let's find x
x = y+3
x = 3+3
x = 6 is the number of TDs scored
--------------------------
Checking the answers:
x+y+z = 6+3+5 = 9+5 = 14 times they scored
6x+3y+z = 6*6+3*3+5 = 36+9+5 = 50 points scored
There are 3 more TDs than FGs since x = y+3 leads to 6 = 3+3 which is a true statement.
All three original equations we set up for the system of equations are true. Therefore, the final answers are confirmed.

LaTanya buys 6 yards of blue fabric and 9 yards of green fabric. The blue fabric costs $2 more per yard than the green fabric. She pays a total of $57. What would be the combined cost of 1 yard of blue fabric and yard of green fabric?
The price of 1 yard of blue fabric and 1 yard of green fabric is obtained by solving the system of linear equations and it is $8
Let
x = price of blue fabric per yard
y = price of green fabric per yard
"The blue fabric costs $2 more per yard than the green fabric" means:
x = y + 2 (Equation 1)
" LaTanya buys 6 yards of blue fabric and 9 yards of green fabric and pays $57" means:
6x + 9y = 57 (Equation 2)
Substitute equation 1 into equation 2:
6x + 9y = 57
6 (y + 2) + 9y = 57
6y + 12 + 9y = 57
15 y = 45
y = 3
Substitute y = 3 into equation 1
x = 3 + 2 = 5
Hence, the price of blue fabric is $5 per yard while the green fabric is $3 per yard.
The price of 1 yard of blue fabric and 1 yard of green fabric = x + y = 3 + 5 = $8

Check your work.
Solve for the variable using only the addition property of equality.
Distribute through the parentheses.
Answer:
use the property’s of equality to solve
Step-by-step explanation:
Use the properties of equality to solve, is not a step when we are solving an equation using distributive property.
Distributive property:- In general,
distribute means to divide something or give a share or part of something. According to this property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.
ex:- a(b+c)=ab+ac
a(b-c)=ab-ac ,also valid true for division
(b+c)/a = b/a + c/a
Steps involved while solving equations
1. If you see parenthesis, with more than one term inside, then distribute first.
2. Rewrite your equations with like terms together. Take the sign in front of each term.
3. Combine like terms.
4. Continue solving to get the answer.

the admission fee at an amusement park is $3.50 for children and 13.00 for adults. on a certain day, 240 people entered the park, and the admission fees collected totaled $1,980.00. how many children and how many adults were admitted?
120 children and 120 adults were admitted to the amusement park if the admission fee collected was $1980.00
The number of children and adults that entered the park can be calculated using linear equations.
Considering x to be the number of adults and y to be the number of children;
As 240 people entered the park, therefore;
x + y = 240
As the fee for children is $3.50 and for adults is $13, therefore;
13x + 3.50y = 1980
Determining the value of y in the first equation;
x + y = 240
y = 240 - x
Putting this value of y in the second equation;
13x + 3.50y = 1980
13x + 3.50(240 - x) = 1980
13x + 840 - 3.50x = 1980
9.5x = 1980 - 840
9.5x = 1140
x = 1140 / 9.5
x = 120
To determine the value of y, we Substitute this value of x in the first equation;
y = 240 - x
y = 240 - 120
y = 120
Hence, 120 children and 120 adults entered the park if the admission fee for children was $3.50 and for adults was $13.00

ANSWER
B) y = 1/2x - 6
EXPLANATION
We have that the line passes through (6 -3) and has a slope of 1/2.
To find the point-slope form of the equation, we have to use the formula:
[tex]y-y_1=m(x-x_1)[/tex]where m = slope = 1/2
(x1, y1) = (6, -3)
So, we have:
y - (-3) = 1/2 (x - 6)
y + 3 = 1/2 x - (1/2 * 6)
y + 3 = 1/2 x - 3
=> y = 1/2x - 3 - 3
y = 1/2x - 6

The table below shows the average price of a Miami Marlins baseball ticket between 2006 and 2021.
The equation y=1.67x−3338.5 models this relationship, where x is the year and y is the average ticket price.
Use the model to predict the ticket price for a Miami Marlins baseball ticket in 2030.
$=
By evaluating the equation in x = 2030, we can estimate the price to be $51.60.
How to use the model?We know that the equation:
y = 1.67*x - 3338.5
Models the relationship between the year, x, and the average ticket price of a Miami Marlins baseball ticket.
We know that this relationship works for the years 2006 to 2021, but can be used to estimate the price for years after and before that.
if we use x = 2030, we will get:
y = 1.67*2030 - 3338.5 = 51.6
This will be the price, in dollars, of a game in the year 2030.

The equation of the line is y = -3x + 8.
What exactly is slope?
The slope of a line, or angle between it and the horizontal, is stated numerically. The slope of a line, ray, or line segment in analytical geometry is the ratio of its vertical to horizontal distance between any two locations ("slope equals rise over run").
Given,
x1 = 1
y1 = 5
m = -3
From,
y-y1 = m(x-x1) (x-x1) (x-x1)
y - 5 = -3(x - 1) (x - 1) (x - 1)
y-5 = -3x + 3
y = -3x + 8
