I would say 13 would be your answer. Hope this helps!
(x,y) = {-2,-5}. I’m pretty sure this is correct. Hope it help!! ❤️
Answer:
1/6
Step-by-step explanation:
jason ate 1/2, so only 1/2 of the pizza is left.
1 ÷ 2 = 1/2
he split it equally between himself and 2 friends (3 people)
1/2 ÷ 3
= 1/2 × 1/3
=1/6
The statement fourth "No, the flowers were not put into groups first and then randomly assigned the two additives would be correct.
<h3>What is random experiment?</h3>
Any well-defined method that yields an observable outcome that cannot be precisely predicted in advance is referred to as a random experiment. To avoid any ambiguity or surprise, a random experiment must be properly defined.
We have:
Total number of flowers selected = 20
And puts in each vase with same amount of water.
10 flowers have been assigned to receive the new additive.
The remaining 10 flowers receive the original additive.
Based on the data, this is not a randomized block design for the experiment because the flowers were not put into groups first and then randomly assigned the two additives.
Thus, the statement fourth "No, the flowers were not put into groups first and then randomly assigned the two additives would be correct.

Answer:
a = 9.849
b = 20.25
c = 491.03
Step-by-step explanation:
By using Pythagoras theorem in the right triangle BDC,
(Hypotenuse)² = (Leg 1)² + (Leg 2)²
BC² = BD² + DC²
a² = 9² + 4²
a = 
a = 
a = 9.8489
a ≈ 9.849 units
By mean proportional theorem,
AD × DC = BD²
b × 4 = 9²
b = 
b = 20.25 units
BY Pythagoras theorem in ΔADB,
AB² = AD² + BD²
c² = b² + 9²
c² = (20.25)² + 9²
c² = 410.0625 + 81
c = 491.0625
c = 491. 063 units
