Answer:

56 teddy bears

Step-by-step explanation:

If each teddy bear weighs 1/4 pounds, then the total weight of teddy bears that can be put on the display is 1/4 pounds * X teddy bears, where X is the number of teddy bears.

The maximum weight the display can hold is 14 pounds, so we need to find the value of X that satisfies the equation: 1/4 pounds * X teddy bears = 14 pounds.

Dividing both sides of the equation by 1/4 pounds, we get: X teddy bears = 14 pounds / 1/4 pounds = 56 teddy bears.

Therefore, the employee can put 56 teddy bears on the display.

Answer:  56 teddy bears on the display.

Step-by-step explanation: We can find the maximum number of teddy bears that can be put on the display by dividing the maximum weight of the display by the weight of each teddy bear. Since each teddy bear weighs 1/4 pounds and the display can hold 14 pounds, we can put a maximum of 14 / (1/4) = <<14/(1/4)=56>>56 teddy bears on display.

For at least 75% of the data, the spread will be within two standard deviations of the mean.

The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers.

While a high standard deviation suggests that the values are dispersed throughout a wider range, a low standard deviation suggests that the values tend to be close to the established mean.

Generally speaking, the spread will be within two standard deviations of the mean for at least 75% of the data.

The data will be within three standard deviations of the mean for at least 89% of the time.

Data that deviates more than two standard deviations from the mean are deemed "unusual."

By using the formula for the distance between two points we will see that the distance between the two points is √80 is 8.9

The length of the line connecting two places represents the distance between them. Subtracting the different coordinates will reveal the distance if the two points are on the same horizontal or vertical line.

Learn how to apply the Pythagorean theorem to find the distance between two points using the distance formula. The Pythagorean theorem can be rewritten as d=(((x 2-x 1)2+(y 2-y 1)2) to calculate the separation between any two locations.

The general formula for the distance between two points (a, b) and (c, d) is:

Distance = √[(a-d)²+(b - c)²]

In this case, we have the points (-4,1) and (4,5), replacing that in the above formula we get:

Distance = √[(-4-4)²+(1-5)²]

= √80

=8.9

The x-intercept and coordinate of the vertex of the given parabola will be x = 1,7 and (4,-9) respectively.

A pair of numbers that employ the horizontal and vertical distinctions from the two reference axes to represent a point's placement on a coordinate plane. typically expressed by the x-value and y-value pairs (x,y).

As per the given parabola,

y = x² - 8x + 7

At x-intercept, y = 0

x² - 8x + 7 = 0

x² - 7x - x + 7 = 0

x(x - 7) - (x - 7) = 0

(x - 1)(x - 7) = 0

x = 1,7

For the vertex, the slope will be zero,

y' = 2x - 8 + 0 = 0

2x = 8

x = 4

Thus, y = 4² - 8 x 4 + 7

y = -9

Thus, the coordinate of the vertex is (4,-9)

Hence "The given parabola's x-intercept and vertex coordinates are x = 1,7 and (4,-9), respectively.".

If the product of their slopes is -1, these lines are perpendicular to each other.

What is perpendicular ?

The word perpendicular means at right angles and this is because when two lines meet, they form right angles. Perpendicular lines can face in any direction such as up and down, crossways, and side-to-side.

The equation of a straight line that is perpendicular to the line y = x is the line y = −x .

E.g. Take the line y = 2x.

Let's construct a perpendicular to the line y = 2x at the point ( 0,3 )

We can therefore state that for any two perpendicular lines y = mx + c and y = nx + c ,

mn = −1 .

If the product of their slopes is -1, these lines are perpendicular to each other.

4x 5y 20 is not an equation and thus cannot be solved. However, if you are looking to find the product of 4x and 5y, then the answer would be 100xy. To calculate this, you must multiply 4x by 5y. This will give you 20x + 20y, which can be simplified to 100xy. To make sure that you reach the correct answer, it is recommended to double check your work.

The measure of the altitude of the triangle shown in the figure given below is  15 inches .

The Altitude of the triangle is defined as the perpendicular distance from the top vertex of the triangle to the base of the triangle.

Also , the altitude of a right triangle is same as height of triangle.

If in the right triangle , the length of altitude is "a units" ,

the length of base is "b units " , and the length of hypotnuse is "c units" .

So , the altitude can be calculated using the formula : a = √(c² - b²) .

from the figure given below , we can see that , c = 25  and b = 20

we get , a = √(25² - 20²)

a = √(625 - 400)

The term area is defined as the total space taken up by a flat (2-D) surface or shape of an object.

Here we have Given the following values,

r = 4 + 8 sin (θ)

Now, we have to substitute the value of r = 0, then we get

⇒ 0 = 4 + 8 sin (θ)

⇒ 8 sin (θ) = -4

⇒ sin θ = -1/2

⇒ θ = -π/6

Therefore, the limit lies in the interval -π/6 to + π/6

Now, the value of Area of polar region is calculated as,

=> A = ∫

Now, by Substituting the values

A=∫π/6−π/6 (4 + 8 sin (θ)) dθ

The stone face is approximately 57.8512 feet in height.

Height is a mathematical term that refers to the vertical distance between an object's top and base.

Sometimes, it has the designation "altitude."

The measurement of an item along the y-axis in coordinate geometry is referred to as height in geometry.

So, let h be the stone's face's height.

One sight is 750 feet away from the mountain's base, and there is a 33° elevation difference between it and the bottom of the face.

The distance between the mountain's base and the base of the stone face

= 750 * tan33°

= 750 * 0.64940759319

= 487.055694898

A different location, which is 36° in elevation and 750 feet from the mountain's base, can be seen from the summit of the face.

The separation between the mountain's base and the top of the stone face = (h + 487.055694898) ft

Now, using trigonometry:

h + 487.055694898/750 = tan36°

h + 487.055694898 = 0.726542525 * 750

h = 544.906896004 - 487.055694898 = 57.8512011059 = 57.8512
