<h3>Answer: Vertical angles</h3>

Explanation:

Ignore the ray that angles 2 and 3 are adjacent to. It might help to copy the drawing but erase that ray in question. All we really care about is the X shape the two lines form along with angles 1 and 4. These two angles are opposite one another. We consider them vertical angles. They don't have to align vertically. They simply have to be opposite one another like this in this X configuration. Vertical angles are always congruent to one another.

A student walked 100 meters north, then 100 meters west. how many more meters did the student walk compared to their total displ
seraphim [82]

Using Pythagorean theorem, the student walked 53.58 meters more compared to the total displacement from the starting point.

If a student walks 100 meters north, then 100 meters west, then the path he travels resembles the sides of a right triangle (see attached photo).

Using Pythagorean theorem, we can solve for the total displacement from the starting point to the end point.

c^2 = a^2 + b^2

where c is the total displacement from the starting point to the end point

a is the distance he walks up north

b is the distance he walks to the west

c^2 = 100^2 + 100^2

c^2 = 10,000 + 10,000

c^2 = 20,000

c = 141.42 meters

Comparing the total distance the student walked and the total displacement from the starting point to the end point by subtraction.

100 meters + 100 meters - 141.42 meters = 53.58 meters

Will AWARD BRAINLIEST! PLEASE HELP! Dasha has 4 times more rose bushes in her garden than Anna. After 39 rose bushes were remove
Lunna [17]

Answer:

d=104

Dasha's garden had 104 originally

Step-by-step explanation:

let d for dasha and a for Anna

d=4a

a=d/4

d-39=a+39

d-39=d/4 +39

d-d/4=39+39

3/4 d =78

3d=4*78

d=(4*78)/3

d=312/3

d=104

Dasha's garden had 104 originally

Ethan is thinking of two numbers. The difference of two numbers is 5. Five times the lesser number minus the greater number is 7
luda_lava [24]
If we write the bigger number as x, and the smaller number as y, we can write it as simultaneous equations.

So, if the difference is 5, we can say that

x-y=5

And if five times the smaller number minus the greater number is 7, then we can write that as

5y-x=7

You can add these together to get 4y=12, and if we simplify, we get y=3.

We know that the difference is 5, so 3+5=8.

Therefore, Ethan's numbers are 3 and 8.

Llana [10]

Answer:

1. mean = 980 median = $895.5

2. 308, 593, 895.5, 1425, 1720

3. 491.7978

4. 895.5

5. 50.28%

Step-by-step explanation:

1. mean $1,589+$593+$1,223+$869+$423+$1,720+$708+$1,425+$922+$308/10

= 9780/10

= $978

median

We first arrange the values in ascending order

308,423,593,708,869,922,1223,1425,1589,1720

number of observation is even so we pick the 2 values in the middle and divide by 2

= 869+922/2

= $1791/2

$895.5

2. five number summary of change

the botom half of th dta set = 308,423,593,708,869

minimum value = 308

n = 5

median = 593 = q1

from 1, q2 = median = $895.5

the upper half of data

922,1223,1425,1589,1720

n = 5

median = $1425

maximum value = $1720

the five number summary of change in cost is therefore

308, 593, 895.5, 1425, 1720

3. standard deviation

s =[\sqrt{x-barx} ]^{2} \frac{1}{n-1}

bar x is the mean = 978

($1,589-978)²+ ($593-978)²+ ($1,223-978)²+ ($869-978)+ ($423-978)²+ $1,720-978)²+($708-978)²+ ($1,425-978)²+ ($922-978)²+ ($308-978)²

= 2176786

=\sqrt\frac{1}{10-1} {2176786} \\\sqrt{ \frac{2176786}{9}

= \sqrt{241865.1}

= 491.7978

4.  middle 50% is spread over the median, which is 895.5

5.  coefficient of variation

= s/bar x * 100

= 491.7978/978 * 100

= 49179.78/978

= 50.28%

6. z score = x - mean/s

x = 1589

= 1589-978/491.7978

= 1.2424

for x = 593

593-978/491.7978

= -0.7828

= 0.7828

for x = 1223

1223-978/491.7978

= 0.4982

for x = 869

869-978/491.7978

= -0.2216

= 0.2216

for x = 423

423-978/491.7978

= -1.1285

= 1.1285

x = 1720

1720-978/491.7978

z = 1.5088

for x = 708

708-978/491.7978

= -0.5490

= 0.5490

for x = 1425

1425-978/491.7978

= 0.9089

for x = 922

922-978/491.7978

= -0.1139

= 0.1139

for x = 308

308-978/491.7978

= -1.3624

= 1.3624
