I believe the radius would be 3.39
Hope this helps! Good luck! :)
Your answer would be x = 1.
The rules for a kite shape is that two pairs are of equal length, which means we can say that AD = CD and thus form an equation:
3x + 4 = x + 6
- x
2x + 4 = 6
- 4
2x = 2
÷ 2
x = 1
I hope this helps!
?!?! whaaatt confused lol
Answer:
D. No, because group A is already the control group.
16% percent of the students paid MORE than Jane.
The mean(μ) of money spent on textbooks is 500
The standard deviation(σ) of money spent on textbooks is 50
Money paid by Jane for her books is $550
We will use this formula,
Ζ=x-μ/σ
To find: the percentage of students paid MORE than Jane for the textbooks
=?
Solution:
≤
=
Ζ≤
=1-P(Ζ≤ 1)
=1-0.8413
=0.1587
≈16%
Therefore, 16% percent (approx) of the students paid MORE than Jane.
