The Pentagon's ABCDE & PQRST Are Similar Find The Length X Of QR Please Help I Will Give 50 Points

Answers

Answer 1

Answer:

x = 3.2

Step-by-step explanation:

Since they are similar the ratio of the side lengths must be the same

Using the bottom side and the unknown side from the left figure and the right figure

5            4

----- = --------

4            x

Using cross products

5x = 4*4

5x = 16

Divide by 5

x = 16/5

x =3.2

Answer:

x = 44.3°

Step-by-step explanation:

Redrawing the triangle,

To obtain x, we can apply the trigonometric relation :

Sin x = opposite / hypotenus

Opposite side = 6.5

Hypotenus = 9.3

Sin x = 6.5/9.3

x = sin^-1(6.5 / 9.3)

x = 44.34

x = 44.3°

Suppose a large shipment of telephones contained 21% defectives. If a sample of size 498 is selected, what is the probability that the sample proportion will differ from the population proportion by less than 3%

Answers

Answer:

[tex]P(-3\% < x < 3\%) = 0.901[/tex]

Step-by-step explanation:

Given

[tex]p = 21\%[/tex]

[tex]n = 498[/tex]

Required

[tex]P(-3\% < x < 3\%)[/tex]

First, we calculate the z score

[tex]z = \sqrt{p * (1 - p)/n}[/tex]

[tex]z = \sqrt{21\% * (1 - 21\%)/498}[/tex]

[tex]z = \sqrt{21\% * (79\%)/498}[/tex]

[tex]z = \sqrt{0.1659/498}[/tex]

[tex]z = \sqrt{0.000333}[/tex]

[tex]z = 0.0182[/tex]

So:

[tex]P(-3\% < x < 3\%) = P(-3\%/0.0182 < z <3\%/0.0182)[/tex]

[tex]P(-3\% < x < 3\%) = P(1.648 < z <1.648)[/tex]

From z probability, we have:

[tex]P(-3\% < x < 3\%) = 0.901[/tex]

7y - 4 = 11

7y - 4 + 4 = 11 + 4

7y = 15

7y ÷ 7 = 15 ÷ 7

You randomly select two poker chips from a bag containing 7 poker chips: 4 red, 1 blue, 1 green, and 1 white. Consider the following events:

Event A: You select a green poker chip

Event B: You select a white poker chip.

Determine whether the following statement is True or False: Events A and B are statistically independent.

Answers

Answer:

P[You select a green poker chip] = 1/7

P[You select a white poker chip] = 1/7

Step-by-step explanation:

Given:

Number of chips beg contain = 7 chips

Number of red chips = 4 chips

Number of blue chips = 1 chips

Number of green chips = 1 chips

Number of white chips = 1 chips

Find:

Event A: You select a green poker chip  

Event B: You select a white poker chip

Computation:

P[You select a green poker chip] = Number of green chips / Number of chips beg contain

P[You select a green poker chip] = 1/7

P[You select a white poker chip] = Number of white chips / Number of chips beg contain

P[You select a white poker chip] = 1/7

Mason had struggled all week trying to find the perfect gift, but nothing seemed right. He first thought about getting her a dress, only to realize that he had no idea what size she wore. Then he thought hed get her a book, since his mother loved to read. But the book shop was large, and Mason couldnt be sure which books she had already read. He thought to himself, I don't know what Mom likes. I want to get her something that will make her happy. Thats when he saw Little Potters Florist and Gardening Shop. His mother loved gardening! Mason ran over to the store. The owner of the store, Angela, was surprised to see Mason. Mason told her he was there to get a gift for his mother. Angela wrapped up five packets of seeds, five planters, and a new weeding fork. She also put together a fresh bouquet of roses for Mason to give to his mother. When the time came to present his gift to his mother, Mason grew anxious. He didnt know whether or not she would like the gardening supplies. He wondered if he should have bought a dress like he had initially planned. Of course, it was too late to make a change, so he went to the kitchen where his mom was busy preparing a chicken dinner. Mason sneaked behind her and placed the gift on the table. He held out the bouquet and shouted, "Happy Birthday, Mama!" His mother was startled, but she accepted the bouquet with a smile. As she began to open the package, Mason could feel nervousness creeping up on him again. His mom remained silent as she removed the contents of the package. She then turned and hugged Mason with tears in her eyes. Mason knew his mother loved the gifts. She always cried when she was really happy.
