Your equation would be y = 210x + 240
Each time you add a night, the price will go up by 210 so each night will have a common difference of 210. This eliminates options C and D.
Going back to the phrase I used "common difference" not "ratio," this tells you to use an arithmetic sequence.
Your answer should be option A if I'm not mistaken (haven't done arithmetic and geometric sequences in quite some time).
Answer:
D. Randomly draw and replace a card 100 times. Then, observe how close to 20 times a club is drawn.
Step-by-step explanation:
We are given that,
Martha predicts that 'whenever she draws a card from the deck without looking, she will draw a club one-fifth of the time'.
Now, according to the options, we see that,
If she randomly draw and replace a card 100 times and then observe how close to 20 times a club is drawn.
Her prediction is most likely to be true.
As, 20 out of 100 times is th of the total time.
Hence, option D is correct.
Answer:
x = 32/67 y = 36/67
Step-by-step explanation:
5x+3y = 4 ------1
14x-5y = 4 -------2
1×5 ; 25x+15y = 20 --------3
2×3 ; 42x-15y = 12 -------4
3+4 ; 67x = 32
x = 32/67
5×(32/67)+3y = 4
y = 36/37
Answer:
333 inches = 27.75 feet = 9.25 yards
Answer:
if those functions under the radical are multiplied together they can be expanded as:
I=((x1+x2)^2 - 1)*(1-(x1-x2)^2)/8
let u=x1+x2 and v=x1-x2
I = (u ^ 2–1) * (1-v ^ 2)
du = dx1 + dx2; dv = dx1-dx2;
dx1 * dx2 = (du-dx2) * (dx1-dv)
or-or-or ...
int(I)*dx1*dx2=5/2
