Andrea has 3 tiles. One is a regular octagon, one is a regular pentagon and one is a regular hexagon. Andrea thinks the 3 tiles

HACTEHA [7]

From calculations, we can say that the given tiles will not fit together perfectly.

<h3>How to find the sum of interior angles of a Polygon?</h3>

If the tiles join perfectly at a point, sum of all angles around the joining point should be 360°.

Expression for the measure of the interior angle of a polygon,

Interior angle of a polygon = [(n - 2) * 180]/n

Interior angle of a pentagon = [(5 - 2) * 180]/5 = 108°

Interior angle of a hexagon = [(6 - 2) * 180]/6 = 120°

Interior angle of an octagon = [(8 - 2) * 180]/8 = 135°

To prove that the given tiles fit together perfectly → Sum of all the angles around the common point should be 360°

Sum of all interior angles = 108° + 120° + 135° = 363°

Therefore, given tiles will not fit together perfectly.

In a grid of a backyard, the vertices of the floor of a shed are (20, 80), (50, 60), (50, 20), and (20, 20). The coordinates are

sdas [7]

Answer:

The area of the floor of the shed is <u>1500 square feet.</u>

Step-by-step explanation:

Given:

The vertices of the floor of a shed are: (20,80), (50,60), (50,20) and (20,20)

Let us plot the given vertices on a graph.

From the graph, it is clear that the given figure is a trapezium with opposite parallel sides being parallel to the y axis. The height of the trapezium is the side that is parallel to x axis.

The area of the trapezium ABCD is given as:

$A=\frac{1}{2}(AB+CD)\times AD$

From the graph, AB = 60 ft, CD = 40 ft, AD = 30 ft

Therefore, the area is given as:

$A=\frac{1}{2}(60+40)\times 30\\A=\frac{1}{2}\times 100\times 30=1500\ ft^2$

Therefore, the area of the floor of the shed is 1500 square feet.

Answer:

a) The mean of the probability distribution = 0.6

b) The variance of the probability distribution = 0.3

c) The standard deviation of the probability distribution = 0.5

Step-by-step explanation:

a) Data and Calculations:

number of dogs per household in a small town

Dogs Probability Expected Mean Diff Mean Diff.

Value Squared

0 0.650 0 -0.569 0.32376

1 0.216 0.216 -0.353 0.12461

2 0.087 0.174 -0.395 0.15603

3 0.026 0.078 -0.491 0.24108

4 0.014 0.056 -0.513 0.26317

5 0.009 0.045 -0.524 0.27458

The mean = 0.569 (Sum of expected value)

Variance = mean of squared differences = 0.27665 (1.38323/5)

Standard deviation = square root of variance = 0.526 = 0.5

Can someone please answer this for me please??

klio [65]

Answer:

15/16

Step-by-step explanation:

Using the order of operations, we need to multiply in the parentheses first...

3/5*25/24=75/120, which simplifies to 5/8.

Next, we need to divide 5/8 by 2/3. To divide, we can actually multiply by the reciprocal, which is flipping the fraction that you are dividing by. In this case, we need to multiply 5/8 by the reciprocal of 2/3. The reciprocal of 2/3 is 3/2, so we need to multiply 5/8 by 3/2.

5/8*3/2=15/16

This is the final answer!

I hope this helped you out!! Have an amazing day φ(゜▽゜*)♪

The side of a square is measured to be 10 ft with a possible error of ±0.1 ft. Use linear approximation or differentials to esti

lorasvet [3.4K]

Answer:

The error in the calculation of the area will be 2 square feet.

Step-by-step explanation:

Let the actual length of the square is L ft.

So, actual area A = L² ......... (1)

Now, if there is an error in measuring length is ΔL, then

(A + ΔA) = (L + ΔL)² {Since if there is an error in length by ΔL, then there will be an error in the calculation of area by ΔA}

⇒ A + ΔA = L² + 2×L×ΔL + (ΔL)²

Now, by linear approximation, neglect the term (ΔL)² as it will be very small.

So, A + ΔA = A + 2×L×ΔL {Since A = L²}

⇒ ΔA = 2×L×ΔL .......... (2)

Now, given that L = 10 ft and ΔL = 0.1 ft.

Hence, ΔA = 2× 10× 0.1 = 2 sq. ft.

Therefore, the error in the calculation of the area will be 2 square feet. (Answer)
