Answer:

Image of proof attached

Step-by-step explanation:

So it is given that ∠1 ≅ ∠4 and we have to find that ∠3 ≅ ∠2.

I am going to show one way to prove this, but there are likely many more ways to prove this.

I hope this helps. Happy studying.

1,8,5,4,1,8,5,4<br>Mean:<br>Median:<br>Mode:

Lynna [10]

Answer:

1. Mean = 55.8

Median = 23

Mode = None

2. Mean = 2.1

Median = 1.4

Mode 0.5

3. Mean = 4.5

Median = 4.5

Mode = 1,4, 5, 8

4. Mean 68

Median 58

Mode = 0

Step-by-step explanation:

Mean = 17 + 25 + 23 + 200 + 14 / 5 = 279/5 = 55.8

Median= Because its odd you put them in order 17, 14, 23, 25, 200 = 23 because it is the middle number. Mode = None

2. Mean = 0.5 + 1.4 + 3.0 + 7.0 + 0.5 +1.8 + 0.5 = 14.7 = 14.7/7 = 2.1

Median = because it is odd you put them in order 0.5, 0.5, 0.5, 1.4, 1.8, 3.0, 7.0 = 1.4 The mode is 0.5 because it repeats three times

3. Mean = 1 + 8 + 5 + 4 + 1 + 8 + 5 + 4 = 36/8 =4.5

Median = Because its even you divide by the two middle numbers = 1, 1, 4,4, 5, 5 , 8 , 8 = 4+5 = 9/2 = 4.5 Mode = 1, 4, 5, and 8 are the numbers that are repeated most often.

Mean = 0+78+99+58+65+0+47+38+227 = 68 Median, Because there is an odd number you get the odd number from the middle. 0, 0, 38, 47, 58, 65, 78, 99, 227 = 58 Mode = 0 because it repeats more often.

Omg please help ASAP me im stuck!

Gwar [14]

Answer:

x= 3, y = 5

Step-by-step explanation:

(45x -5) + (16x + 2) = 180° (because p and q are parallel )

61x = 180 therefore x = 3

(16x +2) + 26y = 180° (because it's a right angle)

we already kniw x is 3 sp just put the values in place and you will find the answer as 5.

An epidemiologic study examined the incidence of symptomatic Chlamydia infection in a cohort of 2000 young women in a county in

seraphim [82]

a. If no one dropped out of the study and no one developed Chlamydia infection during the study period, the total number of person-years = 10,000 person-years (2,000 x 5 years).

<h3>What are person-years?</h3>

Person-years are the product of the number of people in a study and the amount of time each person spends in the study.

Thus, since there are 2,000 women in this study, who spend 5 years each, the person-years are 10,000 (2,000 x 5) person-years.

b. The estimated incidence rate of Chlamydia infection among women who participated in the study is 0.62 or 620 per 1,000 person-years (6,200/10,000).

<h3>What is an incidence rate?</h3>

An incidence rate describes the quickness of disease occurrence in a population. Since the incidence rate is based on person-time, it has some advantages over an incidence proportion, which measures the probability of developing a disease during the specified period.

<h3>Data and Calculations:</h3>

Sample of young women = 2,000

Period of study = 5 years

Subjects newly diagnosed with infection = 440

Total number of person-years of subjects diagnosed = 6,200

Thus, the total number of person-years in the study is <u>10,000 person-years</u>, while the incidence rate is <u>620 per 1,000</u>.

Last week Macy ran 4 times as many miles as Jackson. They ran a total of 20 miles. How many miles did Macy run? how many morr mi

WITCHER [35]

Macy 5 miles because she ran 4 times more than Jackson in relation to Jackson ran 5 mile, this problem can oftenly be seen as
$j = 20 \div 4$
which would end up in the answer being 5 which is the right answer while someone else can see it as
$j = 20 - 4$
which would equal 16 which is incorrect because the problem didn't say that Jackson ran one mile nor 4 miles which would be 4*4 or 16 when the correct answer is 20/4=5 because 4*5=20
