The perimeter and area of the polygon are 72 feet and 300 feet.

"A polygon is a plane shape with straight sides. Polygons are 2 - dimensional shapes. They are made of straight lines, and the shape is closed."

From the given polygon

Perimeter of the polygon = Sum of all sides of the polygon

P = 15 + 16 + 8 + 17 + 16

P = 72 feet

Area of the polygon

A = [tex](\frac{16+16+8}{2}[/tex] × [tex]15)[/tex]

A = 20 × 15

A = 300 feet

Hence, the perimeter and area of the polygon are 72 feet and 300 feet.

Answer:

Step-by-step explanation:

Feet is the unit of measurement. One feet of measurement is equal to the 12 inches.The length of the each rod made by the 5 feet long pipe is 7.5 inches.

The length of the pipes is 5 feet.

Total number of roads made by the pipes is 8.

We need to convert the length of the feet into the inches.

Feet is the unit of measurement. One feet of measurement is equal to the 12 inches.

As it is known that the one feet has the twelve inches. Thus the number of inches in 5 feet is,

[tex]=5\times12[/tex]

[tex]=60[/tex]

Thus the length of the pipe is 60 inches.

Now the total number of roads made by this pipe is 8. Suppose the length of the each rod is [tex]x[/tex] inch. Thus,

[tex]x=\dfrac{60}{8}[/tex]

[tex]x=7.5[/tex]

Thus the length of the each rod made by the 5 feet long pipe is 7.5 inches.

Step-by-step explanation:

Subtract the area of the triangle from the rectangular area. AT=bh/2 and AR=LW so

A=12(10)-7(6)/2

A=120-21

A=99 ft^2

Answer:

Step-by-step explanation:

Now e have two figures

1 is ABCD and other is APQD ,

Now to find g and f,

Now the are both figure is ,

Area = length * width

Area ABCD = 39 cm^2

AB* BC = 39

Again,

Area APQD = AP*QD= 16 cm ^2

from here f =16/g  putt it in above equation we get ,

(g+7)*16/g = 39

16*g-39*g+96 =0

-23g +96 = 0

g = 96/23

g =3 cm

Now for f putt in one of the above equation ,

f =16/3

f =5.33 cm

Answer:

f = 3cm g = 6cm

Step-by-step explanation: to find f

Subtract the area of APQD from ABCD then divide by 7

f = (39 - 18)/7

f = 21/7

f = 3

To find g, divide the area of APQD by 3

18/3 = 6

We can do this because of the givens: ABCD is a rectangle, PQ is parallel to AD, so BC=AD=PQ

Answer:

CD=16

Step-by-step explanation:

If XY is median then CD equals 16

Length of CD = 16 .

An isosceles trapezoid can be defined as a trapezoid in which non-parallel sides and base angles are of the same measure.

Given,

Isosceles trapezoid ABCD with median XY.

Median cuts the non-parallel lines of trapezoid in two equal parts.

then,

AX = 8

AB = 2 × AX

AB = 2 × 8

AB = 16

ABCD is isosceles trapezoid

So, Unparallel lines are equal,

AB = CD

⇒ CD = 16 unit.

Hence, 16 unit is length of CD.

Answer:

B, D, and E

Step-by-step explanation:

B. Five hundred thousand = 500,000/ three hundred = 300/ sixty-eight = 68.

D. 5 hundred thousands = 500,000/ 3 hundreds = 300/ 6 tens = 60/ 8 ones = 8.

E. 500,000 + 300 + 60 + 8 = 500,368.

Answer:

(-9, 0)

Step-by-step explanation:

When a point is reflected over the x-axis, the x-coordinate stays the same but the y-coordinate turns into its opposite. So, the x-coordinate would stay as -9. Because zero is neither negative nor positive, it doesn't have an opposite. So, the y-coordinate would still be 0.

Answer:

Step-by-step explanation:

I assume that "side length" means the slant height of one of the triangular faces.

area of a triangular face = ½(base)(side length) = ½(7)(11.5) = 40.25 in

lateral area = all four triangles = 161 in²

base area = 7² = 49 in²

total surface area = lateral area + base area = 161+49 = 210 in²

The area of the pyramid is  1.4625 ft²

If the base of the pyramid is in the shape of a square (base with 4 sides), then it is called a square pyramid. As the square has 4 sides, then the square pyramid has the following properties: No. of Faces: (4+1) = 5 No.of Vertices: (4+1)= 5 No. of Edges: 2(4) = 8

Given here: The height is 11, the base is 7 in, and the side length is 11.5 inches of a pyramid.

The surface area of a square pyramid is the sum of the areas of its square base and four triangular faces:

SA = BA + (4 × FA)

     =[tex]a^2+a\sqrt{a^2+4h^2}[/tex]

Where a= base length and height = h

Thus inputting the values we get

SA= 7²+7[tex]\sqrt{7^2+4.11^2}[/tex]

   =49+7√533

    =210.60 in²

Thus in ft.² we have 1.4625 ft²

Answer:

D

Step-by-step explanation:

Answer:

A score of 150.25 is necessary to reach the 75th percentile.

Step-by-step explanation:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

A set of test scores is normally distributed with a mean of 130 and a standard deviation of 30.

This means that [tex]\mu = 130, \sigma = 30[/tex]

What score is necessary to reach the 75th percentile?

This is X when Z has a pvalue of 0.75, so X when Z = 0.675.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]0.675 = \frac{X - 130}{30}[/tex]

[tex]X - 130 = 0.675*30[/tex]

[tex]X = 150.25[/tex]

A score of 150.25 is necessary to reach the 75th percentile.

Answer:

0.2275 = 22.75% probability that you actually won that round

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Fireworks going off

Event B: You won

Probability of fireworks going off.

100% of 1/35 = 0.0286(when you win)

10% of 34/35 = 0.9714(you lost). So

[tex]P(A) = 0.0286 + 0.1*0.9714 = 0.12574[/tex]

Probability of you winning and fireworks going off:

100% of 1/35, so [tex]P(A \cap B) = 0.0286[/tex]

If you failed to see the outcome of a round, but you see the fireworks going off, then what is the probability that you actually won that round?

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.0286}{0.12574} = 0.2275[/tex]

0.2275 = 22.75% probability that you actually won that round
