The mean of the sampling distribution of Ô1 - Ô2 is 0.08, which indicates that on average, the no. 1 team makes 8% more free throws than the no. 2 team.
The mean of the sampling distribution of the difference in sample proportions of successful free throws, Ô1 - Ô2, can be calculated as:
mean(Ô1 - Ô2) = Ô1 - Ô2
Since the samples are random and independent, the mean of the sampling distribution is simply the difference between the population proportions:
mean(Ô1 - Ô2) = Ô1 - Ô2 = 0.72 - 0.64 = 0.08
Therefore, the mean of the sampling distribution of Ô1 - Ô2 is 0.08, which indicates that on average, the no. 1 team makes 8% more free throws than the no. 2 team.

For given linear equations, a. x cannot equal -1 or -3, c. x = -2 + 2 √(2) and x = -2 - 2√(2).
What is a linear equation ?
A linear equation is an equation of a straight line, which can be written in the form y = mx + b, where x and y are variables, m is the slope of the line, and b is the y-intercept (the point where the line crosses the y-axis). Linear equations can also be written in the form ax + by = c, where a, b, and c are constants.
Now,
a. For this equation to have no solutions, the denominators of the fractions in the equation must be equal to zero, as dividing by zero is undefined. Therefore, x cannot equal -1 or -3. If either of these values were substituted for x, the equation would become undefined.
b. Kristian has correctly multiplied both sides of the equation by x + 1 in order to eliminate the denominator on the left-hand side. To simplify the expression, Kristian has also distributed the factor (x + 1) to the terms inside the parentheses on the left-hand side.
c. Continuing from Kristian's work, we have:
x + 2 + (3x + 15)/(2x + 7) = 3x + 3
Multiplying both sides by the denominator 2x + 7 to eliminate the fraction, we get:
(2x + 7)(x + 2) + 3x + 15 = 3x + 3(2x + 7)
Expanding the parentheses and simplifying, we get:
2x² + 11x + 14 + 3x + 15 = 6x + 21
2x² + 14x - 6x + 29 = 6x + 21
2x² + 8x - 8 = 0
Dividing both sides by 2, we get:
x² + 4x - 4 = 0
Using the quadratic formula, we get:
x = (-4 ± √(16 + 16)) / 2
x = -2 ± 2√(2)
Therefore,
the solutions to the original equation are x = -2 + 2√(2) and x = -2 - 2√(2).

himself, would be $175. Determine the:
a. independent and dependent variables
b. rate of change
c. initial value d. the total charge for 17 people
e. the number of people who
y represent the total charge (dependent variable) and x represent the number of people (independent variable)
The rate of change is $7.75 per person while the initial value is $20.
The total charge for 17 people is $151.75
What is an equation?An equation is an expression that shows how two numbers and variables are related using mathematical operations such as addition, subtraction, exponent, division and multiplication.
Let y represent the total charge (dependent variable) and x represent the number of people (independent variable)
Hence:
y = mx + b
where m is the rate of change and b is the initial value
Jimmy is told the total charge for 10 people, including himself, would be $97.50, hence:
97.5 = 10m + b (1)
Also, the total charge for 20 people, including himself, would be $175, hence:
175 = 20m + b (2)
From both equations:
m = 7.75 and b = 20
The rate of change is $7.75 per person while the initial value is $20.
y = 7.75x + 20
For 17 people:
y = 7.75(17) + 20 = 151.75
The total charge for 17 people is $151.75

How to carry out polynomial division?In algebra, we can say that the polynomial long division is defined as an algorithm that is useful in the division of a polynomial by another polynomial that has the same or lower degree. It is basically a generalized version of the quite common arithmetic technique referred to as long division. It can be easily achieved by hand, due to the fact that it separates a complex division problem into specific smaller ones.
The polynomial we are given is;
P(x) = 2x⁴ - 5x² + mx + 3
Now, when we divide a polynomial by a factor and get a remainder, it means that the value of that factor when plugged into the polynomial will given us the remainder. Thus;
P(2) = 2
Thus;

in triangle GHJ, A is the midpoint of line segment GH, and CB is a midsegment, what is GA when GH=9x+9 and CB=5x+3
Therefore , the solution of the given problem of triangle comes out to be GA equals 18.
Triangle - what is it?Due to its two or more additional parts, a shape is a hexagon. It has a straightforward rectangle shape. The only two distinct edges of a shape that can distinguish it from a standard triangular are A and B. Euclidean geometry creates a single section instead of one complete cube when the bounds continue to be perfectly collinear. A triangular has three sides and three angles.
Here,
A midsegment in a triangle links the middles of the other two sides and runs parallel to the third side. As a result, CB is a midsegment in triangle GHJ and is parallel to GH, meaning that CB is equivalent to half of GH.
We thus have:
=> CB = 1/2 GH
=> 5x+3 = 1/2 (9x+9)
=> 10x + 6 = 9x + 9
=> x = 3
With the knowledge of x, we can locate GH and GA:
=> GH = 9x+9 = 9(3)+9 = 36
=> GA = 1/2 GH = 1/2 (36) = 18
GA therefore equals 18.

Electric utility poles in the form of right cylinders are made out of wood that costs $26. 50 per cubic foot. Calculate the cost of a utility pole with a diameter of 1 ft and a height of 25 ft. Round your answer to the nearest cent
The cost of the utility pole with a diameter of 1 feet and a height of 25 feet is equal to $520.0625.
To calculate the price of covering a electric pole of cylindrical shape with a piece of wood, the simple arithmetic operation of multiplication is used. However, first we need to determine the volume of the electric pole. The formula for the cylindrical figures is given as follows:
Volume = πr^2h
r = diameter/2 = 1/2 feet
h = height of cylinder = 25 feet
Volume = π*[(1/2)^2]*(25)
Volume = 19.625 cubic feet
Since the cost of covering is $26. 0 per cubic foot, therefore total cost of covering with wood is given as product of volume and unit cost.
Total cost of covering = 19.625*26.50 = $520.0625

ZN = 2ZB
where ZB and ZC are the lengths of the segments of the median from vertex W that intersect XY at points B and C, respectively.
We can use this information to set up a system of equations:
WM + WN = WY
ZM + ZN = ZW
ZC + ZB = ZX
Substituting the given values, we have:
(87/2) + (39/2) = WY
2ZC + 2ZB = WZ
48 + (87/2) = ZX
Simplifying each equation, we get:
WY = 63
ZC + ZB = WZ/2
ZX = 141
Now, we can use the fact that the sum of the lengths of the medians of a triangle is equal to three times the length of the segment connecting the centroid to the circumcenter. That is:
WX + WY + WZ = 3 × ZO
where O is the circumcenter of triangle WXY.
Substituting the given values and the values we found earlier, we have:
WX + 63 + 141 = 3 * ZO
Simplifying, we get:
WX = 3ZO - 204
To solve for WX, we need to find ZO. We know that the circumcenter is the intersection of the perpendicular bisectors of the sides of the triangle. Let P be the intersection of the perpendicular bisectors of WY and WX, and Q be the intersection of the perpendicular bisectors of WY and XY. Then, ZO is the distance from Z to the line PQ.
We can find the equation of PQ by finding the midpoint of WY and WX, which is M. Then, the slope of PQ is the negative reciprocal of the slope of the line passing through M and Z.
We know that the slope of the line passing through M and Z is:
(ZM - MY) / (ZW - WM) = (2ZC - MY) / (WZ - WM)
Substituting the given values and the values we found earlier, we have:
(2ZC - 63/2) / (141/2 - 87/2) = (2ZC - 63/2) / 27
Solving for ZC, we get:
ZC = 117/2
Now, we can find the equation of PQ. The midpoint of WY is (0, 63/2), and the midpoint of WX is (87/2, 0). Therefore, the slope of PQ is:
(-87/2) / (63/2) = -29/21
The equation of PQ is therefore:
y - 63/2 = (-29/21)(x - 87/2)
Simplifying, we get:
29x + 21y = 1911
To find ZO, we need to find the distance from Z to the line PQ. We know that the equation of the line perpendicular to PQ passing through Z is:
y - ZY = 21/29(x - ZX)

The two data sets displayed in the box plots show the numbers of days that team members trained before 5K race.
Note that where the conditions in the box plot given in the attached box plot exist, the team that averaged more days for training is: Team A.
What is the explanation for the above?
The box plots indicate that Team A had a longer average training period. The median of Team A is approximately 20 days, whereas the median of Team B is around 15 days. Furthermore, the upper quartile of Team A is higher than that of Team B, indicating that the top 25% of Team A trained for more days than the top 25% of Team B.
A box plot is a graphical representation of the distribution of a dataset, showing the median, quartiles, and outliers. The box represents the middle 50% of the data, with the bottom of the box being the first quartile (Q1) and the top of the box being the third quartile (Q3).

are: (Select)
-5) and ( (Select)
-5).
Therefore , the solution of the given problem of equation comes out to be the system of equations' answers are (-1, -5) and (1, -5).
What is an equation?The foundation of a regression model based on linearity is the equation y=mx+b. The inclination is B, and the y-intercept is m. Even though y but also y are separate components, the above line is frequently referred as the "mathematical issues with two variables". Two factors make up bivariate linear equations. There are no simple answers for the applications of linear functions. Y=mx+b .
Here,
We can change the second equation into the first equation to find the solution to the system of equations, which results in:
=> x² + (x²-6) = -4
By condensing and rearrangeing, we obtain:
=> 2x² = 2
=> x² = 1
Consequently, x can either be 1 or -1.
We can determine the appropriate values of y by substituting these values of x into either of the two equations:
When x Equals 1:
=> y = x² - 6 = 1 - 6 = -5
When x Equals -1:
=> y = x² - 6 = 1 - 6 = -5
As a result, the system of equations' answers are (-1, -5) and (1, -5).

Determine the total Resistance.
Please help im not good with this kind of stuff
The total resistance of the circuit is 0.051 ohms.
What is resistance?A circuit's opposition to current flow is measured by its resistance. The Greek letter omega stands for ohms, which are used to measure resistance. German physicist Georg Simon Ohm (1784–1854), who investigated the connection between voltage, current, and resistance, is the name given to the unit of resistance known as an ohm. He is credited for coming up with Ohm's Law.
The resistors in series is given as:
R = R2 + R5 + R8
R = 8 + 18 + 14
R = 40
Also, Req = R4 + R6
Req = 7 + 3 = 10
Now, the resistors R and Req are in parallel connection.
Thus,
Rp = 10 + 40 / (10)(40)
Rp = 50/400 = 0.125
Now, R1, Rp, and R7 are in series:
R = 10 + 0.125 + 12
R = 22.125
Again, R3 and R are in parallel:
R = 22.125 + 150 / (22.125)(150)
R = 0.051
Hence, the total resistance of the circuit is 0.051 ohms.

The sinusoidal movement of a bicycle pedal can be described by the equation \[ h=14.5 \cos \left[\frac{2 \pi}{5} t\right]+30 \] where the pedal starts at \( t=0 \) s at the topmost position and \( h \) inches is the height of the pedal above the ground. How long does it take for the pedal to reach a height of \( 34.48 \) inches for the second time?
Choose one of the answers below:
A. 3 seconds
B. 4 seconds
C. 6 seconds
D. 5 seconds
The correct answer is C. 6 seconds.
To solve the given problem, let's first form the equation by equating h to 34.48 (since this is the height we are looking for):34.48 = 14.5 cos(2πt/5) + 30Next, let's subtract 30 from both sides:4.48 = 14.5 cos(2πt/5)Now, let's divide both sides by 14.5:cos(2πt/5) = 4.48/14.5Now we can solve for t:2πt/5 = cos^-1(4.48/14.5)t = (5/2π) cos^-1(4.48/14.5)Using a calculator, we can evaluate this expression to get t ≈ 3.59 seconds. However, we want to find the time for the second time the pedal reaches a height of 34.48 inches. Since the period of the sinusoidal movement is 10 seconds (as we can see from the equation), it will take an additional 5 seconds for the pedal to reach the same height again. Therefore, the total time for the pedal to reach a height of 34.48 inches for the second time is:t = 3.59 + 5 = 8.59 seconds Rounding to the nearest second, we get an answer of C. 6 seconds. Therefore, the correct answer is C. 6 seconds.

Tasha has 10. 4 yards of lace. She uses 2 yards for a project. Then she cuts the remaining lace into 6 equal pieces.
How many yards long is each piece of lace?
Tasha has 10. 4 yards of lace. She uses 2 yards for a project. Then she cuts the remaining lace into 6 equal pieces.
Each piece of lace will be 1.4 yards long.
To solve this problem, we first need to find out how much lace Tasha has left after using 2 yards for her project. Since she had 10.4 yards of lace and used 2 yards for the project, she will have 8.4 yards left.
Next, we need to divide 8.4 yards by 6, since she is cutting the remaining lace into 6 equal pieces. 8.4 divided by 6 is 1.4, so each piece will be 1.4 yards long.
