75,88,90,96,98,100

minimum = 75
Q1 = 88.....this is where the box begins
Q2 (the median) = (90 + 96) / 2 = 186/2 = 93....this is the line in the box
Q3 = 98....this is where the box ends
maximum = 100
                 
                 88_93______98
75_______|      |              |___100
                   |___|_______|

200m - 100m + 48,250 = 50,250 – 150m
drek231 [11]

200m - 100m + 48,250 = 50,250 - 150m

(Add or subtract common variables)

100m + 48,250 = 50,250 - 150m

(Add 150m to both sides)

250m + 48,250 = 50,250

(Subtract 48,250 to both sides)

250m = 2000

(Divide 250 to both sides to isolate m)

m = 8

Can you figure out the formula
puteri [66]

If "a" and "b" are two values of x-coordinate, and "m" is the midpoint between them, it means the distance from one end to the midpoint is the same as the distance from the midpoint to the other end

... a-m = m-b

When we add m+b to this equation, we get

... a+b = 2m

Solving for m gives

... m = (a+b)/2

This applies to y-coordinates as well. So ...

... The midpoint between (x1, y1) and (x2, y2) is ((x1+x2)/2, (y1+y2)/2)

_____

Jennifer had (x1, y1) = (-4, 10) and (x2, y2) = (-2, 6). So her calculation would be

... midpoint = ((-4-2)/2, (10+6)/2) = (-6/2, 16/2) = (-3, 8)

Brandon had (x1, y1) = (9, -4) and (x2, y2) = (-12, 8). So his calculation would be

... midpoint = ((9-12)/2, (-4+8)/2) = (-3/2, 4/2) = (-1.5, 2)

hi there

40.3

Step-by-step explanation:

28547=100%

11504=R

11504 x 100=1150400/28504

1150400/28504=40.29 = 40.3

Find cos(2* angle ABC) 100 POINTS
Simora [160]

Answer:

3/5

Step-by-step explanation:

We need to use the trig identity that cos(2A) = cos²A - sin²A, where A is an angle. In this case, A is ∠ABC. Essentially, we want to find cos∠ABC and sin∠ABC to solve this problem.

Cosine is adjacent ÷ hypotenuse. Here, the adjacent side of ∠ABC is side BC, which is 4 units. The hypotenuse is 2√5. So, cos∠ABC = 4/2√5 = 2/√5.

Sine is opposite ÷ hypotenuse. Here, the opposite side of ∠ABC is side AC, which is 2 units. The hypotenuse is still 2√5. So sin∠ABC = 2/2√5 = 1/√5.

Now, cos²∠ABC = (cos∠ABC)² = (2/√5)² = 4/5.

sin²∠ABC = (sin∠ABC)² = (1/√5)² = 1/5

Then cos(2∠ABC) = 4/5 - 1/5 = 3/5.
