A florist wants to determine if a new additive helps extend the life of cut flowers longer than the original additive does. The florist selects 20 flowers of different types and puts each flower in its own vase with the same amount of water. She positions the vases so they also receive the same exposure to light. She numbers the flowers 1–20, and places these numbers on equal-sized slips of paper. The slips are placed in a hat and mixed thoroughly. A slip is chosen and the corresponding flower receives the new additive. After the hat is shaken, another slip is chosen and the corresponding flower also receives the new additive. This procedure continues until 10 flowers have been assigned to receive the new additive. The remaining 10 flowers receive the original additive. Is this a randomized block design for this experiment?

Yes, each flower is randomly assigned to the treatments.
Yes, the flowers were placed in their own vases, and received the same amount of water and light.
No, only 20 flowers were used in the experiment.
No, the flowers were not put into groups first and then randomly assigned the two additives.

ok

step-by-step explanation:

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2
