The table to set up a System of equations to solve for the number of laps walked and run if the total distance is 24 laps.the correct answer is not listed among the options given.

The table to set up a system of equations to solve for the number of laps walked and run if the total distance is 24 laps:

3 + 5 = A   (the total number of laps walked and run is equal to A)

B + 10 = C   (the total number of laps walked and run is equal to C)

15 + D = 40  (the total number of laps walked and run for the week is 40)

Simplifying each equation, we get:

A = 8

B = 5

C = 15

D = 25

To find how many laps will the participants walk and run if the total distance is 24 laps, we can set up the following proportion:

3x/8 + 5x/15 = 24

Multiplying both sides by 120 (the least common multiple of 8 and 15), we get:

45x + 40x = 2880

Simplifying, we get:

85x = 2880

Dividing both sides by 85, we get:

x ≈ 33.88

Therefore, the participants will walk approximately:

3x/8 ≈ 12.66 laps

And run approximately:

5x/15 ≈ 21.22 laps

Rounding to the nearest whole number, we get:

They will walk 13 laps and run 21 laps.

Therefore, the correct answer is not listed among the options given.

The vertex is at (1, 4).

The vertex is at (-1, -4).

The axis of symmetry is x = 1.

The axis of symmetry is x = -1.

The x-intercepts are (3, 0) and (-1, 0).

The x-intercepts are approximately (-2.3, 0) and (0.3, 0).

The y-intercept is (0, 3).

The y-intercept is (0, -6).

We have,

To solve the equations using the quadratic formula, we need to rewrite them in the standard form ax² + bx + c = 0.

-x² + 2x + 3 = 0 can be rewritten as -1x² + 2x + 3 = 0

Here, a = -1, b = 2, and c = 3

Using the quadratic formula, we have:

x = (-b ± √(b² - 4ac)) / 2a

x = (-2 ± √(2² - 4(-1)(3))) / 2(-1)

x = (-2 ± √(16)) / -2

x = 1 ± 2

So, x = 3 or x = -1

2x² + 4x - 6 = 0 is already in the standard form with a = 2, b = 4, and c = -6

Using the quadratic formula, we have:

x = (-4 ± √(4² - 4(2)(-6))) / 2(2)

x = (-4 ± √(52)) / 4

x = (-2 ± √(13)) / 2

To find the vertex of each parabola, we can use the formula x = -b / 2a and then substitute the value of x into the equation to find y.

For -x² + 2x + 3 = 0

We have a = -1 and b = 2, so the vertex is at

x = -b / 2a = -2 / (2(-1)) = 1.

Substitute x = 1 into the equation to find y:

y = -1(1)² + 2(1) + 3 = 4.

So the vertex is at (1, 4).

For 2x² + 4x - 6 = 0,

We have a = 2 and b = 4, so the vertex is at x = -b / 2a = -4 / (2(2)) = -1. Substitute x = -1 into the equation to find y: y = 2(-1)² + 4(-1) - 6 = -4.

So the vertex is at (-1, -4).

The axis of symmetry is a vertical line that passes through the vertex.

For -x² + 2x + 3 = 0, the axis of symmetry is x = 1.

For 2x² + 4x - 6 = 0, the axis of symmetry is x = -1.

To find the x-intercepts, we can set y = 0 in each equation and solve for x using the quadratic formula.

For -x² + 2x + 3 = 0, we have:

x = (-2 ± √(2² - 4(-1)(3))) / 2(-1)

x = (-2 ± √(16)) / -2

x = 1 ± 2

So the x-intercepts are (3, 0) and (-1, 0).

For 2x² + 4x - 6 = 0, we have:

x = (-4 ± √(4² - 4(2)(-6))) / 2(2)

x = (-4 ± √(52)) / 4

x = (-2 ± √(13)) / 2

So the x-intercepts are approximately (-2.3, 0) and (0.3, 0).

To find the y-intercept, we need to set x = 0 and solve for y.

Setting x = 0 in -x² + 2x + 3 = 0.

-0 + 0 + 3 = 3

Therefore, the y-intercept is (0, 3).

Setting x=0 in 2x² + 4x - 6.

2(0)² + 4(0) - 6 = -6

Therefore, the y-intercept is (0, -6).

Thus,

The vertex is at (1, 4).

The vertex is at (-1, -4).

The axis of symmetry is x = 1.

The axis of symmetry is x = -1.

The x-intercepts are (3, 0) and (-1, 0).

The difference between the sample means is A = ( 4√10/3 )

Given data ,

Difference between sample means A = (t-statistic) * (estimated standard error) / √(1/n1 + 1/n2)

On simplifying , we get

To find the difference between the sample means, we need to multiply the estimated standard error by the t-statistic and then divide by the square root of the sum of the reciprocals of the sample sizes.

Given that the estimated standard error is 2 points, the t-statistic is 1.500, and the sample sizes are n1 = 8 and n2 = 10, we can substitute these values into the formula:

Difference between sample means = (1.500) x (2) / √(1/8 + 1/10)

Calculating the sum of the reciprocals of the sample sizes:

1/8 + 1/10 = 5/40 + 4/40 = 9/40

Difference between sample means = (1.500) x (2) / √(9/40)

A √(9/40) = √(9) / √(40) = 3 / (2 x √(10))

Difference between sample means = 1.500 x 2 x (2 x √(10) / 3)

Difference between sample means ≈ 4√(10) / 3

Therefore, the difference between the sample means is ( 4√10/3 )

There are 58 Adventure Scouts slept outside on the camping trip.

Let's denote the number of scouts who slept in a cabin, tent, and outside as c, t, and o, respectively. We know that the total number of scouts is 115, so:

c + t + o = 115

We also know that twice as many scouts slept in a cabin as slept in a tent, so:

c = 2t

And we know that the same number of scouts slept outside as slept in a cabin, so:

o = c

We can use these equations to solve for the number of scouts who slept outside:

c + t + o = 115

2t + t + t = 115 (substituting c = 2t and o = c)

4t = 115

t ≈ 28.75

Since we can't have a fractional number of scouts, we need to round this up or down. However, we also know that the number of scouts who slept outside is the same as the number who slept in a cabin, which means that either c or o must be even (since c is twice t). Therefore, we'll round t up to 29 and use that to solve for c and o:

c = 2t ≈ 58

o = c ≈ 58

So, we can conclude that 58 Adventure Scouts slept outside on the camping trip.

The solution is, $85,500 are the total cost savings for Leather Stuff.

Explanation:

In this case, we need to calculate the saving per zipper which is external price minus agreed transfer price.

Then, we will multiply the saving per zipper by the quantity of zipper required by Leather Stuff, which is 90,000 zippers.

Cost saving per zipper

= External price - Agreed transfer price

= $3.50 - $3.25

= $0.25

Total cost saving

Answer:

54300 ml is greater than 54 L. This is because 54300 ml is equivalent to 54.3 L, which is larger than 54 L.

Answer: n = 70

Step-by-step explanation:

The sum of all angles in a triangle is 180 degrees. We know this because the formula for degree measure in a polygon is (180) * (n-2) where n is the number of sides. (ie a square with 4 sides would have 360 total degrees because (180) * (4-2) = 360)

Given the angle of 40 degrees we know that the remaining angles need to add up to 140 degrees. because n = n we can say that 2n = 140 divide by 2 and get n=70

The area of the parallelogram with vertices A(-12, 2), B(6, 2), C(-2, -3), and D(-20, -3) is 90 units².

To find the area of a parallelogram, we need to know the length of one of its bases and its corresponding height. We can find the length of the base by computing the distance between two parallel sides of the parallelogram.

In this case, we can see that sides AB and CD are parallel, and they both have a length of 18 units (6 - (-12) = 18).

To find the height, we need to compute the distance between the parallel sides. We can do this by computing the vertical distance between either AB and CD or AD and BC.

Let's use AD and BC. The vertical distance between A and D is 5 units (2 - (-3) = 5), and the vertical distance between B and C is also 5 units (2 - (-3) = 5). Therefore, the height of the parallelogram is 5 units.

Now we can use the formula for the area of a parallelogram:

Area = base x height

Area = 18 x 5

Area = 90 units²

It's important to note that shifting a function involves changing the corresponding variables (x or y) in the equation to achieve the desired translation.

The parabola y = x^2 represents a standard upward-opening parabola with its vertex at the origin (0, 0). To shift this parabola down by 3 units, we subtract 3 from the y-coordinate of each point on the original parabola. Thus, the equation of the shifted parabola becomes y = x^2 - 3.

Similarly, to shift the parabola to the left by 2 units, we subtract 2 from the x-coordinate of each point on the original parabola. The equation of the parabola shifted down by 3 units and to the left by 2 units is y = (x + 2)^2 - 3.

In the shifted parabola, the vertex will be at the point (-2, -3). The parabola retains its general shape, but its position in the coordinate plane has changed. It is now translated 2 units to the left and 3 units down compared to the original parabola y = x^2.
