Step-by-step explanation:
total marbles=11+4=15
plastic yellow marbles=4/2=2
P=(plastic marbles)/(total marbles)=2/15
Answer:
a. f<g is one of them. On the number line, g is closest to 0, meaning it is greater than f.
b. h>0 is one answer. H is to the right of 0, meaning that h is greater than 0.
c. im sorry, i dont know.

If this is graded, I hope you get a good grade!
Answer:
The answer is 3.2 E 3 or 3.2 x 10^3
You move back 3 spaces which is 3.2, since you moved back 3 spaces, you put 3 as the power/exponet.
To be more satisfied, 3.2 is your base number, it is the big number Below the power/exponent. The power/exponent is 3, you moved 3 spaces and you moved to the left, so it is represented as a positive power/exponent.
Hope this helps.
The answer is (1/2)xe^(2x) - (1/4)e^(2x) + C
Solution:
Since our given integrand is the product of the functions x and e^(2x), we can use the formula for integration by parts by choosing
u = x
dv/dx = e^(2x)
By differentiating u, we get
du/dx= 1
By integrating dv/dx= e^(2x), we have
v =∫e^(2x) dx = (1/2)e^(2x)
Then we substitute these values to the integration by parts formula:
∫ u(dv/dx) dx = uv −∫ v(du/dx) dx
∫ x e^(2x) dx = (x) (1/2)e^(2x) - ∫ ((1/2) e^(2x)) (1) dx
= (1/2)xe^(2x) - (1/2)∫[e^(2x)] dx
= (1/2)xe^(2x) - (1/2) (1/2)e^(2x) + C
where c is the constant of integration.
Therefore,
∫ x e^(2x) dx = (1/2)xe^(2x) - (1/4)e^(2x) + C
