Use properties to rewrite the given equation. Which equations have the same solution as 2.3p – 10.1 = 6.5p – 4 – 0.01p? Select two options.
The solution for the equation 2.3p - 10.1 = 6.5p - 4 - 0.01p is p = -4.19/6.1
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 = 9 is an equation.
We have,
2.3p - 10.1 = 6.5p - 4 - 0.01p
Solve for p.
2.3p - 10.1 = 6.5p - 4 - 0.01p
Combining the like terms.
2.3p - 10.1 = 6.49p - 4
4 - 10.1 = 6.49p - 2.3p
-6.1 = 4.19p
p = -4.19/6.1
Thus,
The solution is p = -4.19/6.1

Four friends shared the cost of a pizza dinner. They ordered 1 large pizza for $17.50, 4 sodas for $1.25 each, and 4 salads. Salads normally cost $1.75 but were on sale: "Buy one, get one free." If the friends split the total cost of dinner equally, what was each person's share?
Answer:
$6.50
Step-by-step explanation:
So writing out everything
1 Pizza = $17.50
1 soda = $1.25
1 salad = $1.75
Exception; Salad is buy 1 get 1 free, so only 2 salads were paid for
Now we multiple
1 Pizza * 17.50 = 17.50
4 soda * 1.25 = 5
2 salad * 1.75 = 3.50
Now we add
17.50 + 5 = 22.50 + 3.50 = $26.00
Now lastly, we divide by 4 since there are 4 friends
26/4 = 6.5
Giving us a answer of $6.50
Find the inverse Laplace transforms of the following functions. First, perform partial-fraction expansion on G(s); then, use the Laplace transform table. (a). G(s)= 1 / s(s+2)(s+3) (b). G(s)= 10 / (s +1)^2(s+3) (c). G(s)= [100(s+2) / s(s^2 + 4)(s+1)] e^-x
(d). G(s)= 2(s+1) / s(s^2+s+2) (e). G(s)= 1 / (s+1)^3 (f). G(s)= 2(s^2+s+1) / s(s+1.5)(s^2 +5s+5)
(g). G(s)= [2+2se^(-x) + 4e^(-2x)] / [s^2 + 3s + 2] (h). G(s) = 2s+1 / (s^2 + 6s^2 +11s +6)
(i). G(s) = (3s^3 + 10s^2 + 8s + 5) / (s^4 + 5s^3 + 7s^2 + 5s +6)
The inverse Laplace transform of G(s) is 1 + 2e^(-2t) + 3e^(-3t).
(a). G(s)= 1 / s(s+2)(s+3)
Using partial fraction expansion, we can write G(s) as 1/s + 2/s+2 + 3/s+3. Then, using the Laplace transform table, we can find the inverse Laplace transform of each of these fractions. The inverse Laplace transform of 1/s is 1, the inverse Laplace transform of 2/s+2 is 2e^(-2t) and the inverse Laplace transform of 3/s+3 is 3e^(-3t). Therefore, the inverse Laplace transform of G(s) is 1 + 2e^(-2t) + 3e^(-3t).
(b). G(s)= 10 / (s +1)^2(s+3)
Using partial fraction expansion, we can write G(s) as 5/s+1 + 5/s+3. Then, using the Laplace transform table, we can find the inverse Laplace transform of each of these fractions. The inverse Laplace transform of 5/s+1 is 5e^(-t) and the inverse Laplace transform of 5/s+3 is 5e^(-3t). Therefore, the inverse Laplace transform of G(s) is 5e^(-t) + 5e^(-3t).
(c). G(s)= [100(s+2) / s(s^2 + 4)(s+1)] e^-x
Using partial fraction expansion, we can write G(s) as 50/s + 50/s+1 + 50/s+2 + 50/s+4. Then, using the Laplace transform table, we can find the inverse Laplace transform of each of these fractions. The inverse Laplace transform of 50/s is 50, the inverse Laplace transform of 50/s+1 is 50e^(-t), the inverse Laplace transform of 50/s+2 is 50e^(-2t) and the inverse Laplace transform of 50/s+4 is 50e^(-4t). Therefore, the inverse Laplace transform of G(s) is 50 + 50e^(-t) + 50e^(-2t) + 50e^(-4t)e^-x.

Two points should be noted: The 15% is first calculated using your annual gross wage rather than your take-home pay. Second, the business match is not included in your 15%.
Should I contribute more than 15% to retirement?You probably won't need to save more than 15-20 percent as you get older if you can save 15-20 percent of your salary when you're 30 for retirement. If you stay consistent throughout your professional life, starting early is a tremendous advantage.Your actual monthly contribution will increase when your salary increases if you consistently set aside 15% of your income, which will speed up the accumulation of your retirement savings.If you are under 72 years old and have income from a job or self-employment, you are eligible to make a contribution to your Individual Retirement Account (IRA) of up to $6,000.

In each figure for what values of x and y is the figure a parallelogram
The values of x and y that makes the figure a parallelogram are x = 17 and y = 26
How determine what values of x and y makes the figure a parallelogram?
A parallelogram is a four-sided geometric shape that has opposite sides that are parallel to each other.
The opposite sides of a parallelogram have the same length, and the opposite angles are also equal. The opposite sides of a parallelogram are also known as the bases, and the other two sides are known as the legs.
Since the opposite sides of a parallelogram are equal in length, we can say:
3x + 6 = 4 - x
3x + x = 4 - 6
4x = -2
x = -2/4
x = -1/2 = -0.5
y + 2 = 2y - 3
2 + 3 = 2y - y
5 = y
y = 5
Likewise, the opposite angles of a parallelogram are equal, so we can say:
(4x - 12)° = (3x + 5)°
4x - 12 = 3x + 5
4x - 3x = 5 + 12
x = 17
(3y + 46)° = (5y - 6)°
3y + 46 = 5y - 6
46 + 6 = 5y - 3y
52 = 2y
2y = 52
y = 52/2
y = 26
Thus, x = 17 and y = 26 makes the figure a parallelogram

(the student moves her hand out of the way.)
It takes 0.7143 seconds for the ball in the air to hit the ground.
Therefore the answer is 0.7143 s.
The time it takes for the ball to hit the ground can be calculated using the formula for vertical motion with constant acceleration (g = 9.8 m/s²):
t = √(2 * h / g)
where h is the height the ball is thrown and t is the time it takes to hit the ground.
Plugging in the values to find time:
t = √(2 * 2.50 m / 9.8 m/s²)
t = √(0.51) s
t = 0.7143 s

A confidence interval for estimating the cricket's true probability of landing on its feet is more narrow after the final 10 jumps than it was before the final 10 jumps. Thus, the correct answer is option D.
A confidence interval is a range of values that is likely to contain the true population parameter (in this case, the true probability of the cricket landing on its feet) with a certain level of confidence. The width of the interval depends on the sample size and the level of confidence.
In the first 50 jumps, the cricket landed on its feet 35 times out of 50, giving a proportion of 0.7. Based on this sample, a 95% confidence interval for the true probability of the cricket landing on its feet can be calculated. However, this interval will be relatively wide due to the small sample size.
In the final 10 jumps, the cricket landed on its feet only twice out of 10, giving a proportion of 0.2. Based on this sample, a 95% confidence interval for the true probability of the cricket landing on its feet can be calculated. However, this interval will be relatively narrow due to the large sample size.
When comparing the two intervals, it is clear that the interval based on the final 10 jumps is narrower than the interval based on the first 50 jumps.

the distribution of the time it takes for different people to solve a certain suduko puzzle is strongly skewed to the right, with a mean of 30 minutes and std of 15 minutes. the distribution of z-scores for those times is:
The distribution of z-scores would be a normal distribution centered at 0, with a standard deviation of 1.
The distribution of time it takes for people to solve a certain Sudoku puzzle is strongly skewed to the right. This means that most people take a shorter amount of time to solve the puzzle, but some take a longer amount of time. The mean (average) of this distribution is 30 minutes and the standard deviation is 15 minutes.
To find the distribution of z-scores, we need to convert the times into z-scores, which is done by subtracting the mean (30) from each time and then dividing by the standard deviation (15). This gives us a new distribution of z-scores, which is centered at 0 (since the mean of the times was subtracted from each time) and has a standard deviation of 1.

The proportion of electric toothbrush prices are between 104.60 dollars and 108.20 dollars are 0.0099.
What is Normal Distribution?A normal distribution in statistics is defined as the type of continuous probability distribution where the datas are arranged in a symmetrical bell shaped graph.
Given that,
Mean, μ = 87
Standard deviation, σ = 8
We have to calculate P (104.60 < x < 108.20).
For that find z score.
z = (x - μ) / σ
At x = 104.60, z = (104.60 - 87) / 8 = 2.2
At x = 108.20, z = (108.20 - 87) / 8 = 2.65
From the z table,
P(z < 2.65) = 0.9960 and P(z < 2.2) = 0.9861
P (104.60 < x < 108.20) = 0.9960 - 0.9861 = 0.0099

Solve the system of linear equations by substitution.
5x+2y=9
x+y=-3
problem solving you go on a hayride to take photographs of landmarks. the map shows your path and two landmarks. each unit in the coordinate plane corresponds to 10 yards. approximate your minimum distance from the giant pumpkin. if necessary, round your answer to the nearest tenth.
The minimum distance from the giant pumpkin is 8.9 yards.
We will use the minimum distance formula between a line and a point to obtain the distance in this case.
A linear function is given according to the standard notation by:
Ax+By+C=0
A point with 'x' and 'y' coordinates are given by:
P(x*,y*)
The formula to find the shortest distance between a point and a line is denoted by the formula:
d=|Ax*+By*+C|/√(A²+B²)
In this issue, the path's line includes:
When x = 0, and y = 0, the intercept is 0.
0.5 slope means that when x rises by 4, y rises by 2.
Thus, y=1/2x
-1/2x+y=0
or, -x+2y=0
The coefficients of the line are:
A=-1 and B=2
Coordinates of the giant pumpkin is (x*,y*)=(-4,-3)
Therefore, the minimum distance is:
d=|(-1)(-4)+2(-3)|/√5
or,d=2/√5
or, d=0.89 units
We know, 1 unit=10 yards
or, 0.89 units=8.9 yards
Thus, the minimum distance between a point and a line is 8.9 yards.

find an equation for the surface consisting of all points p for which the distance from p to the x-axis is 3 times the distance from p to the yz-plane.
The surface consisting of all points p for which the distance from p to the x-axis is 3 times the distance from p to the yz-plane.
The equation for the surface consisting of all points p for which the distance from p to the x-axis is 3 times the distance from p to the yz-plane is given by -
x = 3y2 + 3z2
To explain this equation, let us consider a point P(x, y, z) on the surface. The distance from this point P to the x-axis is given by |x|, and the distance from P to the yz-plane is given by √y2 + z2.
Now, the given condition states that the distance from P to the x-axis is 3 times the distance from P to the yz-plane. This can be written as |x| = 3√y2 + z2. By squaring both sides, we get x2 = 9(y2 + z2), which can be rearranged to give the equation x = 3y2 + 3z2.
This equation thus gives the surface consisting of all points p for which the distance from p to the x-axis is 3 times the distance from p to the yz-plane.
