Answer:
A school year is 36 weeks long, so 3/4 of the school year is 36 * (3/4) = 27 weeks.
If Sunny works at the library for three weeks longer than three over four of the school year, he works for 27 + 3 = 30 weeks.
So, Sunny works at the library for 30 weeks in the school year.
The number of weeks in the school year that Sonny worked at the library is; 30 weeks
How to solve Algebra Word problems?We are told that Sunny works at the library for three weeks longer than three over four of the school year a school year is 36 weeks long.
Now, since he works three weeks longer than three over four of the school year, then the expression is;
³/₄(36) + 3
= 27 + 3
= 30 weeks
That figure represents the number of weeks in the school year that Sonny worked at the library.

The life span of fruit fly have a bell shaped distribution, with a mean of 32 days and a standard deviation of 5 days. What is the Z score of the fruit flys at 37 ,30 and 47 days
Answer:
The Z-score (also known as a standard score) represents the number of standard deviations a value is away from the mean of a distribution. The formula for the Z-score is:
Z = (X - μ) / σ
Where X is the value of interest, μ is the mean of the distribution, and σ is the standard deviation of the distribution.
Given the information in the problem, we know that the mean of the fruit fly's lifespan is 32 days and the standard deviation is 5 days.
To find the Z-score of a fruit fly whose lifespan is 37 days:
Z = (37 - 32) / 5 = 1
To find the Z-score of a fruit fly whose lifespan is 30 days:
Z = (30 - 32) / 5 = -0.4
To find the Z-score of a fruit fly whose lifespan is 47 days:
Z = (47 - 32) / 5 = 2.4
Therefore, a fruit fly whose lifespan is 37 days has a Z-score of 1, a fruit fly whose lifespan is 30 days has a Z-score of -0.4, and a fruit fly whose lifespan is 47 days has a Z-score of 2.4.

3 c 9 8. following is a statement of a theorem about certain cubic equations. for this theorem, b represents a real number. theorem a. if f is a cubic function of the form f .x/ d x 3 x c b and b > 1, then the function f has exactly one x-intercept. following is another theorem about x-intercepts of functions: theorem b. if f and g are functions with g.x/ d k f .x/, where k is a nonzero real number, then f and g have exactly the same x-intercepts. using only these two theorems and some simple algebraic manipulations, what can be concluded about the functions given by the following
Both f(x) and g(x) have one x-intercept at x = -1/3.
Theorem A states that for a cubic function of the form f(x) = x^3 + x + b, with b > 1, the function f has exactly one x-intercept. Using Theorem B, we can conclude that for any nonzero real number k, the function g(x) = kf(x) = kx^3 + kx + bk also has exactly one x-intercept.
For example, if f(x) = x^3 + x + 5 and k = 2, then g(x) = 2x^3 + 2x + 10. Both f(x) and g(x) have exactly one x-intercept. This can be shown by solving the quadratic equation formed by setting f(x) = 0 or g(x) = 0. Doing this yields x = -1/3. Therefore, both f(x) and g(x) have one x-intercept at x = -1/3.4

Mason is working two summer jobs, making $7 per hour babysitting and making $10 per hour clearing tables. In a given week, he can work at most 12 total hours and must earn no less than $90. If xx represents the number of hours babysitting and yy represents the number of hours clearing tables, write and solve a system of inequalities graphically and determine one possible solution.
Answer: We know that:
x + y = 12 (because he can work at most 12 hours in total)
7x + 10y ≥ 90 (because he must earn no less than $90)
We can graph these inequalities on the coordinate plane.
The equation x + y = 12 represents a line with a slope of -1 and y-intercept of 12. This is the line that separates the region where he works more hours babysitting and the region where he works more hours clearing tables.
The inequality 7x + 10y ≥ 90 represents the region where he earns more than $90.
You can find the solution by finding the intersection of the line and the shaded region. The solution will be a point that lies on both the line and the shaded region.
One possible solution would be for Mason to work 8 hours babysitting and 4 hours clearing tables, earning him $56 from babysitting and $40 from clearing tables, for a total of $96.

{27}$ of his pizza. If the remaining portions from the three pizzas are put together, what fraction of a large pizza do they make? Express your answer as a common fraction.
The remaining portions from the three pizzas together make up 13/27 of a large pizza.
What is the fraction?A fraction is defined as a numerical representation of a part of a whole that represents a rational number.
Shauntee ate 2/3 of her pizza, so she has 1/3 left.
Carlos ate 8/9 of his pizza, so he has 1/9 left.
Rocco ate 26/27 of his pizza, so he has 1/27 left.
To determine the combined fraction of the remaining portions of the three pizzas, we add the fractions that are left:
1/3 + 1/9 + 1/27 = (1/3) + (1/9) + (1/27)
Simplifying this fraction by finding the least common denominator, which is 27:
(1/3) + (1/9) + (1/27) = (9/27) + (3/27) + (1/27) = 13/27

Parallelogram EFGH is shown below. Give the coordinates of G.
←*
F (0,s)
E (-1,0)
G (?, ?)
H (u,0)
Answer:
G(u+t, s)
Step-by-step explanation:
Given coordinates E(-1, 0), F(0, s), and H(u, 0) of parallelogram EFGH, you want the coordinates of point G.
Segment lengthSegment FG is a horizontal line. Its length will be the same length as horizontal line EH. Since the lines are horizontal, the length is the difference of x-coordinates.
Point H is (u -(-t)) = u+t units to the right of point E. The x-coordinate of point G will be the same number of units to the right of point F.
The x-coordinate of G is 0 +(u+t) = u+t, the length of EH added to the x-coordinate of F.
Horizontal lineThe y-coordinates of any point on a horizontal line are the same. The y-coordinate of point F is 's'. Point G lies on that same horizontal line, so has the same y-coordinate.
The coordinates of point G are (u+t, s).

The midpoints of the diagonals are the same. This means ...
(E+G)/2 = (F+H)/2
E+G = F+H . . . . . . multiply by 2
G = F +H -E . . . . . subtract E
Using the given coordinates:
G = (0, s) +(u, 0) -(-t, 0) = (0+u+t, s+0+0) = (u+t, s) . . . . as above
All of your "parallelogram" problems are worked the same way. The fourth point has coordinates that are the sum of the coordinates of the end points of the known diagonal, less the known point on the unknown diagonal.
If you work the problem any of several other ways, you get the same answer.
Point E is (u -(-t)) = (u +(-t)) units away from point H. Point G will be located the same amount of units to the right of point F in terms of its x-coordinate. G(u+t, s)
What are the possible coordinates of Parallelogram?You need to know the coordinates of point G in the parallelogram EFGH given the coordinates E(-1, 0), F(0, s), and H(u, 0).
FG is a horizontal segment. It will have a length equal to that of a horizontal line, EH. The length is determined by the difference in x-coordinates because the lines are horizontal.
The length of EH multiplied by the x-coordinate of F yields the x-coordinate of G, which is 0 +(u+t) = u+t.
Horizontal line
In a horizontal line, all points have the same y-coordinates. Point F has the y-coordinate of's'. Point G's y-coordinate is the same because it is located on the same horizontal line.
The coordinates of point G are (u+t, s).

Using the given coordinates:
G = (0, s) +(u, 0) (u, 0) (-t, 0) = (u+t, s) + (u+t, s) + (u+t, s) . . . . As mentioned earlier
Your “parallelogram” issues are all solved in the same manner. The fourth point's coordinates are equal to the sum of the coordinates of the known diagonal's end points, minus the known diagonal's known point.
The solution is the same regardless of how you approach the issue.
Vertical line
Any point on a horizontal line has the same y-coordinates. Point F's y-coordinate is's'. Point G has the same y-coordinate since it is located on the same horizontal line.
Point G's coordinates are (u+t, s).

The diagonals' midpoints are identical. This implies...
(E+G)/2 = (F+H)/2
E+G = F+H, multiply by 2, and so on.
G = F + H -E.... Remove E.
Using the coordinates provided:

Use the motion map to answer the question. A motion map. The position line is a long black arrow pointing right with x as the reference point at left. Above the line are 3 dots with short vector arrows moving toward x, then a dot, then 2 dots with longer vector arrows moving away from x. Describe the position and velocity of the object based on the motion map.
The direction and position of the fourth and fifth arrows indicate that the object then moves towards the origin, with a smaller velocity.
What are Motion maps?Motion maps are used to illustrate the direction and position of an object. Using the motion map, the description of the object position and velocity is as follows:
The object starts its movement from the origin with a large velocity, before moving back to the origin with a smaller velocity. It stops for 1 second in the origin, then moves away with a larger velocity, Finally, it moves back towards the origin with a smaller velocity.
See attachment for the motion map, where the number on each arrow in the map, represents the position of the object.
Note that; the long arrow means large velocity while the short arrow means small velocity.
We analyze the direction and position using the arrows
The first arrow shows that the object starts from the origin with a large velocity.The direction and length of the second arrow show that, the object then returned to the origin with a smaller velocity.There is a dot in front of the second arrow. This dot indicates that the object stops for one second.The third arrow means that, the object moved from the origin with a larger velocityThe direction and position of the fourth and fifth arrows indicate that the object then moves towards the origin, with a smaller velocity.Therefore, the direction and position of the fourth and fifth arrows indicate that the object then moves towards the origin, with a smaller velocity.

Answer:
Based on the motion map, the object starts at the reference point "x" on the left side of the position line. The three dots with short vector arrows moving toward "x" indicate that the object is moving in the direction of the reference point and gaining speed. This suggests that the object is accelerating. Then, there is a single dot, which might indicate a momentary pause or a constant velocity. Afterward, the two dots with longer vector arrows moving away from "x" suggest that the object is decelerating or slowing down. In summary, the motion map shows an object that starts from rest, accelerates towards the reference point, maintains a constant velocity for a brief moment, and then decelerates away from the reference point.

john maintains two separate lines of lobster traps in penobscot bay. the east bay trap produces a mean of 12 pounds of lobsters per day with a standard deviation of 7 pounds. the west bay trap produces a mean of 10 pounds of lobsters a day with a standard deviation of 4.5 pounds. the weight of lobsters produced by each trap is independent of the other. which of the following are the mean and approximate standard deviation of the total weight of lobsters john traps in a day? (a) Mean 11; Standard deviation-2.50 (b) Mean 2; Standard deviation-2.50 (c) Mean-2; Standard deviation- 5.36 (d) Mean- 2; Standard deviation -8.32 (e) Mean 2; Standard deviation 11.50
The mean and approximate standard deviation of the difference in the total weight of lobster john traps in a day are 2 pounds and 8.32 pounds respectively. Hence, option d is the right answer.
Since the weight of lobsters produced by each trap is independent of the other, we can find the mean and standard deviation of the difference in the total weight of lobsters trapped in a day by subtracting the mean and standard deviation of the west bay trap from the mean and standard deviation of the east bay trap.
Mean = 12 pounds (east bay) - 10 pounds (west bay) = 2 pounds
Standard deviation = √(7^2 + 4.5^2) = √69.25 ≈ 8.32 pounds
So, the mean and approximate standard deviation of the difference in the total weight of lobsters trapped in a day is -

exercise 1.2.3 the augmented matrix of a system of linear equations has been carried to the following by row operations. in each case solve the system.1 2 1 3 1 | 10 1 -1 0 1 | 1c = 0 0 0 1 -1 | 00 0 0 0 0 | 0
The presented system of linear equations has no solution.
The final form of the augmented matrix suggests that the system of linear equations has no solution, as the last row represents an equation with 0 = 0, which is always true but doesn't provide any information about the variables.
To see this more clearly, let's use the augmented matrix to write out the system of linear equations:
1x - 1y + 2z = 4
2y + 1z = -1
z = 1
The first two equations are consistent and have a unique solution, but the last equation is trivial and provides no information about x and y. In other words, infinitely many pairs of x and y satisfy the first two equations, but none satisfy the third equation. Therefore, the given system of linear equations has no solution.

The numeric value of the function is given as follows:
2x + h + 9.
How to find the numeric value of a function or of an expression?To find the numeric value of a function or of an expression, we replace each instance of the variable in the function or in the expression by the value at which we want to find the numeric value.
The function in this problem is given as follows:
f(x) = x² + 9x.
At x = x + h, the function is defined as follows:
f(x + h) = (x + h)² + 9(x + h)
f(x + h) = x² + 2xh + h² + 9x + 9h
f(x + h) = x² + 2xh + h² + 9x + 9h.
Subtracting by f(x), we have that:
f(x + h) - f(x) = h² + 2xh + 9h.
f(x + h) - f(x) = h(h + 2x + 9).
Dividing by h, the numeric value is given as follows:
2x + h + 9.
Meaning that the first option is the correct option.

A graph that represents the solution set of the compound inequality is: graph D.
What is an inequality?In Mathematics, an inequality simply refers to a mathematical relation that is typically used for comparing two (2) or more numerical data and variables in an algebraic equation based on any of the following inequality symbols:
Less than (<).Greater than (>).Greater than or equal to (≥).Less than or equal to (≤).Next, we would solve the given compound inequality by making x the subject of formula as follows;
x + 3 < 1/2(4x - 12) < 20
Multiplying all through by 2, we have the following:
2x + 6 < 4x - 12 < 40
Next, we would solve the compound inequality in parts:
2x + 6 < 4x - 12
4x - 2x < 12 + 6
2x < 18
x < 18/2
x < 9.
4x - 12 < 40
4x < 40 + 12
4x < 52
x < 52/4
x < 13.
In conclusion, the line on a number line (graph) should be open when the inequality symbol is greater than (>) or less than (<).

B. In square EFGH, find the length of EG.
Answer:
6√2
Step-by-step explanation:
You want one side of a square whose half-diagonal has length 6.
Right triangleIf X is the center point of the square where the diagonals cross at right angles, triangle EXG is an isosceles right triangle with leg length 6. The hypotenuse of an isosceles right triangle is √2 times the leg length, so ...
EG = 6√2
__
Additional comment
If you like, you can use the Pythagorean theorem to prove that.
EG² + EX² +GX² = 6² +6² = 72
EG = √72 = √(36·2) = 6√2
A square is a rhombus, so the diagonals cross at right angles. A square is a rectangle, so the diagonals are the same length. A square is a parallelogram, so the diagonals bisect each other.

Step-by-step explanation:
1 3/4 cups of pecans per pie = 1.75 cups.
For 5 pies, 5 × 1.75 cups = 8.75 cups are needed.
1 cup = 99 g
8.75 cup × (99 g) / (1 cup) = 866.25 g
Exact conversion: 453.59237 g = 1 lb
866.25 g × (1 lb)/(453.59237 g) = 1.91 lb
Answer: 1.91 lb
