I did this my sophmore year in highschool and I'm trying to remember lol. But first you add all the marbles together. 1+4+3. its eight. and since the marble was put back in this makes it an independant event. i believe the answer would be 2/8 considering that there isnt enough numbers to follow through with the equation of (P(a or b)=P(a)xP(b) . P is the probability and a and b are the variabls that represent the events. You would plug in the numbers of the probabilities into the equation, if you think the question calls for it. sorry it may not have been a staright up answer.

Answer:
Step-by-step explanation:
Given that a nutrition lab tested 40 hot dogs to see if their mean sodium content was less than the 325-mg upper limit set by regulations for "reduced sodium" franks
90% confidence interval is
(317.2, 326.8)mg.
Using confidence intervals,we can check whether null hypothesis is true.
Here

(left tailed test at 10% significance level)
We check whether confidence interval 90% contains the mean value.
We find 325 belongs to the confidence interval
Hence H0 is true
The hot dogs do not satisfy.
Answer:
1/5x^12 * y^8.
Step-by-step explanation:
((5x^8*y^7/25)x^4)(y)
=1/5x^12 * y^8.
Answer: (2,-2)
Step-by-step explanation:
Rotating 90 degrees counterclockwise (about the origin) maps (x,y) onto (-y,x), so the answer is <u>N'(2,-2)</u>
