Line D and C shows direct variation because the line goes through the origin my good sir or ma'am :)
Five eights or 5/8 ( Hope This Helped)
Answer: (1,-1)
Step-by-step explanation:
Midpoint of BC=(6+4)/2, (3–1)/2. =(5,1)
Slope of BC is (3+1)/4–6)= 4/-2 = -2
Slope of perpendicular bisector of BC =+1/2
Eqn of perpendicular bisector is : Y-1 =1/2 (x-5)
Y=1/2 •(x-5) +1
Midpoint of AB. (6–2)/2, (3–1)/2 ={2,1)
Slope of AB is(3+1)/(-2–6) = 4/-8 =-1/2
Slope of perpendicular bisector = +2
Eqn of perpendicular bisector is Y-1. =2( X-2)
Y=2X-4+1 = 2X -3
Solving Y=(X-5)/2 +1
& Y=2X-3
2X-3 =(x-5/2)+1
2X-4 =(x-5/2)
4X-8 = x-5
3X =3
X=1
Y= 2×1–3= -1
Circumcentre is(1,-1)
Answer: 
Step-by-step explanation:
You can calculate the area of a kite with the following formula:
Where 
is the length of a diagonal and 
is the length of the other diagonal.
In this case, you can identify that:
Therefore, the final step is to substitute the values into the formula.
Then, the area is:
Answer:
14.6%
Step-by-step explanation:
Use binomial probability:
P = nCr pʳ (1−p)ⁿ⁻ʳ
where n is the number of trials,
r is the number of successes,
and p is the probability of success.
Here, n = 10, r = 4, and p = 1/4.
P = ₁₀C₄ (1/4)⁴ (1−1/4)¹⁰⁻⁴
P = 210 (1/4)⁴ (3/4)⁶
P ≈ 0.146
There is an approximate 14.6% probability that exactly 4 of the 10 adults are on a diet.
