Answer:
y = 11
x = 8.6
Step-by-step explanation:
The small triangle with 30,32,y looks like right triangle
so according to formula a^2 + b^2 = c^2
so 30^2 + y^2 = 32^2
900 + y^2 = 1024
y^2 = 124 => y = 11
The larger triangle also looks like a right triangle
so according to formula a^2 + b^2 = c^2
(30 + 10)^2 + 22^2 = (32 + x)^2
1600 + 44 = (32 + x)^2
so (x + 32)^2 = 1644
x + 32 = 40.55
x = 40.55 = 32 = 8.55 = 8.6
Answer:
A. Independent samples
Step-by-step explanation:
This experiment is comparing the results between two independent samples. Paired samples consist of data for which each point in one sample would be paired to a specific data point in another sample. In the present study, there are no naturally occurring pairs since only the proportions, for the whole sample, of students with colds were compared. Therefore, the answer is:
A. Independent samples

Answer:
3x
Step-by-step explanation:
The area of a triangle is (base × height)/2.
In this picture, the base is 3.
The height is 2x.
(3×2x)/2
=6x/2
=3x
This is a simple "solve for x" equation.
5k-2k=12
3k=12
k=4
You should try doing some more on your own, as this will be coming up a lot in the future.
