Answer 1

Answer:

2 people's 2222222222222222

Answer 2
The ratio of people in the survey who took Echinacea is 27/100The ratio of participants who took vitamin C reported having a cold in the last 30 days is 15/100 or 3/20The ratio of people who reported having a cold took zinc is 5/100 or 1/20.

What are the types of surveys?

Surveys can be used for more than just gathering data from a group of individuals. Surveys give you a clear understanding of your client's attitudes toward your business, products, and services. Online surveys, in-person interviews, focus groups, panel sampling, telephone surveys, post-call surveys, mail-in surveys, pop-up surveys, mobile surveys, and kiosk surveys are the ten most popular survey techniques.

Given, A friend surveyed 100 individuals who used vitamin C, zinc, or echinacea supplements to ward off the common cold. If they had a cold or not in the previous 30 days was the question posed to the participants. Hence,

The ratio of people in the survey who took Echinacea

= people took echinacea/ total people

= 27/100

The ratio of participants who took vitamin C reported having a cold in the last 30 days = 15 / 100 = 3/20

The ratio of people who reported having a cold took zinc = 5/100 = 1/20.

Therefore, 27/100 respondents in the Survey reported using echinacea.  3/20 people who took vitamin C reported having a cold within the previous 30 days. 1/20, of those who took zinc, also reported having a cold.

1. Find the surface area of a triangular prism with height
30 inches, and a right triangle base with side lengths 15 inches and 20 inches, and hypotenuse length 25 inches.

2. What is a hypotenuse length in the most simple terms that you can explain it

Answers

Hey love! <3

Answer:

1. 2100 inches^2

Step-by-step explanation:

Let's solve this together! First you have to find the lateral area.

The lateral area is the product of the perimeter of the base and the height.

The perimeter of the base is 15 in.+20 in.+25 in.=60 in... So the lateral area is 60 in.⋅30 in.=1800 in.2.

Now the base area is 12⋅20 in.⋅15 in.=150 in.2.

There are two bases, so the surface area is 1800 in.2+150 in.2+150 in.2=2100 in.2.

2. A hypotenuse is the longest side of a right-angled triangle.

Step-by-step explanation:

Hypotenuses are the side opposites of the right angle. The length of the hypotenuse of a right triangle can be found using the Pythagorean theorem, which states that the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides in a geometric equation.

To balance a seesaw, the distance a person is from the fulcrum is inversely proportional to his or her weight . Roger , who weighs 120 pounds is sitting 6 feet from the fulcrum . Ellen weighs 108 pounds . How far from the fulcrum must she sit to balance the seesaw ? Round to the nearest hundredth of a foot .

Answers

Answer:

[tex]d_e =6.67ft[/tex]

Step-by-step explanation:

From the question we are told that:

Weight of Roger [tex]W_r=120\ pounds[/tex]

Distance of Roger from fulcrum [tex]d_r=6 ft[/tex]

Weight of Ellen [tex]W_e=120\ pounds[/tex]

Generally the equation for distance-weight relationship is mathematically given by

  [tex]d\alpha \frac{1}{W}[/tex]

  [tex]\frac{d_1}{d_2} =\frac{W_2}{W_1}[/tex]

  [tex]\frac{d_r}{d_e} =\frac{W_e}{W_r}[/tex]

Therefore

 [tex]\frac{d_e}{d_r} =\frac{W_r}{W_e}[/tex]

 [tex]d_e =\frac{W_r*d_r}{W_e}[/tex]

 [tex]d_e =\frac{6*120}{108}[/tex]

 [tex]d_e =6.67ft[/tex]

Therefore the distance from the fulcrum she must sit to balance the seesaw is given as

[tex]d_e =6.67ft[/tex]

Question: Find m HK...

Answers

Answer:

104degrees

Step-by-step explanation:

From the given diagram, line LJ bisects KN, hence arcKL = arcHJ

Given

arHJ = 4x

arc KJ = x+39

Equating both

4x = x+39

4x - x = 39

3x = 39

x = 39/3

x = 13

Since arcHK = arcHJ + arcKJ

arcHK = x+39+4x

arcHK = 5x+39

arcHK = 5(13) + 39

arcHK = 65+39

arcHK = 104degrees

Hence the measure of arcHK is 104degrees

Find X and Y using the image.

Answers

Answer:

x = 59°

y = 130°

Step-by-step explanation:

Find x:

Recall: the measure of an inscribed angle = ½(measure of intercepted arc), based in the inscribed angles theorem

Therefore,

x = ½(118°)

x = 59°

Find y:

y = 2(180 - (56 + x)) => inscribed angles theorem

Plug in the value of x

y = 2(180 - (56 + 59))

y = 2(180 - 115)

y = 2(65)

y = 130°
